Year-Long NASA On The Air Event Kicks off on December 11

Wed, 11/22/2017 - 11:55

The Amateur Radio clubs at National Aeronautics and Space Administration (NASA) centers around the US have invited the Amateur Radio community to join the NASA On The Air (NOTA) special event. NOTA gets under way in December 2017 and continues through December 2018. In addition to being the agency’s 60th anniversary, 2018 will mark 50 years since NASA orbited the first human around the moon, and 20 years since the first elements of the International Space Station (ISS) were launched into low-Earth orbit.

 

Starting on Monday, December 11, 2017 (UTC), Amateur Radio club stations at various NASA centers and facilities will be on the air with special event operations to celebrate these monumental achievements, as well as current milestones. Some clubs will offer commemorative QSL cards, and a special certificate will be available indicating the number of NASA club stations worked on various bands and modes.

 

“We plan to have a web-based system for you to check your points total and download a printable certificate at the end of the event in December 2018,” the NASA announcement said. “Points will be awarded for each center worked on each band and mode (phone, CW, digital, and ‘space’ modes — satellites, meteor scatter, EME, ISS APRS).” That would, of course, include contacts with any of the Amateur Radio stations on the ISS.

 

Key anniversaries during NOTA include the 45th anniversary of Apollo 17 on December 11, 2017, which kicks off the event; NASA’s founding on July 29, 1958; the 20th anniversary of the ISS first element launch on November 20, 1998; the 20th anniversary of the ISS Node 1 Launch on December 4, 1998, and the 50th anniversary of Apollo 8 — launched on December 21, 1968, and returned on December 27 — marking the end of the event.

 

Ham radio clubs at various NASA facilities will sponsor their own special events to commemorate and celebrate specific events.

 

“We hope to be on the air for casual contacts and contests as well. All contacts with NASA club stations will count toward your total,” the announcement said. “QSL cards can be requested from each club you work and details will be on the individual QRZ.com profile page for each club call sign.”

Mysterious Signals Did Not Come from Missing Submarine ; MF/HF Frequencies Listed

Mon, 11/20/2017 - 13:23

Satellite signals heard over the weekend did not come from a missing Argentine Navy submarine San Juan that went missing on November 15, dashing hopes that the vessel could be located. The submarine had reported a malfunction, had surfaced, and was headed back to its base when the Navy lost contact with it. The sub, built in Germany in the 1980s, carries a crew of 44.

Vessels from Argentina, the US, Great Britain, Chile, and Brazil have joined other vessels and aircraft looking for the submarine.

A Naval commander told media today that the submarine had surfaced and reported “an electrical problem” before it disappeared some 270 miles off the South American coast on its return to its base at Mar del Plata.

Over the weekend, Argentina’s Defense Ministry reported receiving seven “failed satellite calls” that officials thought might be coming from the missing submarine. No contact was made, and no transmissions occurred. Poor weather has complicated the search.

Over the weekend, IARU Region 2 News Editor Joaquín Solana, XE1R, issued a list of marine frequencies, suggesting that radio amateurs and SWLs listen for any signals that could be related to the missing San Juan. Frequencies are 2,065.0 kHz; 2,182.0 kHz; 3,023.0 kHz; 3,860.6 kHz; 4,125.0 kHz; 4,143.6 kHz; 6,218.6 kHz, and 8,528.0 kHz on HF, as well as 42.395 MHz, 43.040 MHz, and 84.470 MHz. The MF emergency frequencies of 416 kHz, 437 kHz, and 500 kHz also were suggested.

IRN – International Radio Network

Mon, 11/20/2017 - 06:52

The IRN (International Radio Network) is a VoIP/RoIP system using Teamspeak 3 (TS3) that allows radio users to TX/RX using RF around the World using  different devices (Mobile Phones, Tablets, Computers etc) for free.

The system also allows users to create private talkgroups for point to point or private group QSO’s.
If you would like to add your link, repeater or hub to the IRN system, please use the contact us section to drop us a line.
TS3 is available on Apple, Android, PC, Mac and Linux. The IRN has it’s own private server allowing hundreds of connections at once. There are different talkgroups (channels) within that allow users full RX/TX capabilities across different radio networks and systems from across the globe.
To make it more interesting, you can use PTT-enabled smartphones like the ones listed below. Most of the hams use PTT-enabled phones, so they can use the IRN with the same style as they use a handheld radio. The IRN talk groups can be accessed via GPRS / 3G / 4G / Wifi or RF (depending on the repeaters).

Please note: This system is free to use for both non-licensed* & licensed hams. Live ham-radio repeaters can only be accessed by licensed hams.

*Non-licensed users must apply for membership of IRN in order to have a callsign generated for them (Don’t worry, it’s also free).

The following devices have a dedicated PTT button that will make your experience even better when using the IRN.

New InnovAntennas Quads

Mon, 11/20/2017 - 06:35

NEW FOR 2018!

Following on from our successful LFA-Q compact quads, we are adding a more traditional looking quad to our range which boasts two of the features of the LFA-Q. It is a Rigid quad using tubes rather than wires (which enhances gain) and uses twin booms top and bottom to complete a very sturdy package. The antenna looks more like a traditional quad too being very square in appearance although the height of the quad elements are the same, just the element width changes in length.

The example pictured is for 50MHz and has a boom length of just 53cms yet packs a mighty punch with 7.6dBi forward gain and 18dB F/B and like all G0KSC designed antennas has a direct 50Ohm feed so no matching device losses or noise and no input power limit!

This first-of-breed Quads is installed at G0KSC for testing and a full range down to 21MHz will be applied to the range for the coming year.

IARU Participation in ITU-Radiocommunication Consultations Called “Mutually Beneficial”

Sun, 11/19/2017 - 10:00

International Amateur Radio Union (IARU) President Tim Ellam, VE6SH/G4HUA, has praised the value of the IARU’s participation over the years in International Telecommunication Union (ITU) International Radio Consultative Committee (CCIR) and ITU Radiocommunication Sector (ITU-R) study groups. CCIR was the forerunner to ITU-R. In an article, “The International Amateur Radio Union and CCIR/ITU–R” in the latest issue of ITU News Magazine (see page 55), Ellam said the IARU has been a “regular contributor” to the CCIR and ITU-R study groups and working parties on behalf of the world’s Amateur Radio community. This year marks the 90th anniversary of CCIR/ITU-R study groups; the IARU was first admitted to the work of CCIR in 1932.

“The relationship is mutually beneficial,” Ellam wrote. “The Amateur and Amateur-Satellite services offer…private citizens…the opportunity to intercommunicate and experiment with radio transmission to increase their personal knowledge and skills. Radio amateurs [provide] communications at no cost with their own equipment in the event of natural disasters. They share what they learn with one another and with the wider telecommunications community, in part through ITU–R Recommendations and Reports.”

ITU–R Study Group 5 and Working Party 5A (WP-5A) are home to both the Amateur and the Amateur-Satellite services. ITU-R Study Groups met this past week in the run-up to World Radiocommunication Conference 2019 (WRC-19). Working Group 5A1, chaired by Dale Hughes VK1DSH, is responsible for WRC-19 Agenda Item 1.1, which is looking into a 50-54-MHz band allocation in Region 1, harmonized with the allocations in Regions 2 and 3.

ITU-R Recommendation M.1732, “Characteristics of systems operating in the Amateur and Amateur-Satellite services for use in sharing studies,” was developed by and updated in WP-5A. “The IARU also participates, as appropriate, in other Working Parties of Study Group 5,” Ellam explained.

ITU–R also maintains the standard for International Morse code characters and operational provisions, Ellam pointed out. He noted that while radio amateurs experiment with advanced digital coding and signal processing techniques, they are also the world’s largest group of regular International Morse code users.

Ellam said unwanted emissions that lead to interference — sometimes called spectrum pollution — are of growing concern to radio amateurs. “The radio spectrum is an irreplaceable natural resource,” he said. “Unintended and unnecessary radio frequency emissions from poorly maintained electric power lines and poorly designed electronic devices and systems can cause interference that degrades the capacity of the radio spectrum to support communication.”

Ellam said that as new technologies such as wireless power transmission (WPT) are developed, it’s essential that the highest possible priority be given to developing and implementing standards to prevent radio spectrum pollution.

Ellam said an increasing number of short-mission, non-geostationary satellites are being proposed “for operation in the limited amateur-satellite allocations,” inconsistent with the objectives of the Amateur-Satellite Service. He said the IARU appreciates efforts within ITU-R working parties “to identify more suitable spectrum for telemetry, tracking, and command of these satellites” at WRC‑19.

“The IARU congratulates the ITU–R Study Groups for continuing to build on the magnificent record of the CCIR in furthering the advancement of radiocommunication,” Ellam concluded.

Ellam is an invited panelist at the 90th anniversary celebration of the CCIR/ITU-R Study Groups on November 21 in Geneva.

RadFxSat (Fox-1B) Launched Successfully, Designated AO-91

Sat, 11/18/2017 - 15:49

The latest CubeSat in the Fox series — RadFxSat (Fox-1B) — launched today (November 18) from Vandenberg Air Force Base in California. The Delta II vehicle lifted off at 0948 UTC.

“Following a picture-perfect launch, RadFxSat was deployed at 1109 UTC,” AMSAT reported. “Then the wait began. At 1212 UTC, the AMSAT Engineering team, watching ZR6AIC’s WebSDR waterfall, saw the characteristic ‘Fox Tail’ of the Fox-1 series FM transmitter, confirming that the satellite was alive and transmitting over South Africa. Shortly after 1234 UTC, the first telemetry was received and uploaded to AMSAT servers by Maurizio Balducci, IV3RYQ, in Italy. Initial telemetry confirmed that the satellite was healthy.”

In the wake of the successful launch, deployment, and reception, OSCAR Number Administrator Bill Tynan, W3XO, designated the new satellite as AMSAT-OSCAR 91 (AO-91).

AMSAT Engineering reminds stations that the satellite will not be available for general use until the on-orbit checkouts are complete. AMSAT asks listeners to submit telemetry from RadFxSat (Fox-1B) to assist the Engineering team in completing the commissioning process. Experiment telemetry is downlinked via the DUV sub-audible telemetry stream, which can be decoded using FoxTelemsoftware.

A 1U CubeSat, RadFxSat (Fox-1B) is a joint mission of AMSAT and the Institute for Space and Defense Electronics (ISDE) at Vanderbilt University. The Vanderbilt package is intended to measure the effects of radiation on electronic components, including the demonstration of an on-orbit platform for space qualification of components as well as to validate and improve computer models for predicting radiation tolerance of semiconductors.

AMSAT constructed the rest of the satellite, including the spaceframe, on-board computer, and power system. The Amateur Radio package is similar to that currently on orbit on AO-85, with an uplink on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz.

RadFxSat (Fox-1B) was a secondary payload on the United Launch Alliance (ULA) Delta II rocket carrying the Joint Polar Satellite System-1 (JPSS-1) mission into space. RadFxSat (Fox-1B) is one of four CubeSats making up this NA SA Educational Launch of Nanosatellites (ELaNa) XIV mission, riding as secondary payloads aboard the JPSS-1 mission.

In keeping with long-held ULA tradition, the Delta II launcher paid tribute to deceased employees. Emblazoned on the side of the booster were the names of the late Eric G. Lemmon, WB6FLY, and George Dean. — Thanks to AMSAT News Service via Paul Stoetzer, N8HM, Bill Tynan, W3XO, and Chuck Kimball, N0NHJ

RadFxSat (Fox-1B) Launch Reset for November 18; More Foxes are on the Way!

Sat, 11/18/2017 - 09:44

The twice-delayed launch of the United Launch Alliance (ULA) Delta II rocket that will transport the AMSAT RadFxSat (Fox-1B) CubeSat carrying an Amateur Radio payload and other payloads into orbit now is set for Saturday, November 18, at 0947 UTC. The Joint Polar Satellite System (JPSS)-1 mission launch from Vandenberg Air Force Base, California, had to be postponed on November 14, “due to a range safety hold and high upper-level winds,” ULA said in a tweet. The launch had to be put off on November 6 due to a faulty battery on the booster. AMSAT will blog on the launch in real time on launch day, and NASA-TV will cover the event.

RadFxSat is one of four CubeSats making up this NASA Educational Launch of Nanosatellites (ELaNa) XIV mission, riding as secondary payloads aboard the JPSS-1 mission.

RadFxSat is a partnership with Vanderbilt University’s Institute for Space and Defense Electronics (ISDE) and hosts four payloads for the study of radiation effects on commercial off-the-shelf components. It will carry a Fox-1 style FM U/V repeater with an uplink on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz. Satellite and experiment telemetry will be downlinked via the DUV subaudible telemetry stream, which can be decoded using FoxTelem software.

AMSAT will have more information on the launch and its early operations, and it will post the first telemetry reception. More launch updates are available from ULA via FacebookTwitter, or Instagram, hashtags #DeltaII and #JPSS1.

More Foxes to Come!

Meanwhile, progress continues on getting future Fox payloads into space. On November 6, AMSAT Vice-President Engineering Jerry Buxton, N0JY, delivered Fox-1D to Spaceflight, Inc in Seattle, where it was integrated into its Innovative Solutions in Space QuadPack for delivery to India. Fox-1D will launch on the next ISRO Polar Satellite Launch Vehicle (PSLV) flight, scheduled to take place by the end of December.

In addition to the Fox-1 U/V FM transponder, Fox-1D will carry several university experiments, including a MEMS gyro from Pennsylvania State University-Erie, a camera from Virginia Tech, and the University of Iowa’s High Energy Radiation CubeSat Instrument (HERCI) radiation mapping experiment.

Fox-1D also carries the AMSAT “L-Band Downshifter,” which gives the option of utilizing a 1.2 GHz uplink for the FM transponder.

The NASA ELaNa XX mission that will carry RadFxSat-2 (Fox-1E) into orbit will take place no earlier than the end of next March, AMSAT reported recently. The ELaNa XX mission will carry 12 CubeSats constructed by NASA and by several universities around the US. That mission will be launched by Virgin Galactic on its LauncherOne air launch to orbit system from Mojave, California. Like RadFxSat (Fox-1B), RadFxSat-2 is a partnership opportunity between Vanderbilt University’s ISED and AMSAT and will carry a similar radiation effects experiment, studying new FinFET technology.

RadFxSat-2 will be the fifth Fox-1 satellite built by AMSAT. Fox-1A, now AMSAT-OSCAR 85 (AO-85), was launched on October 8, 2015 and is fully operational, providing science data from its onboard experiments and FM transponder service for the Amateur Radio community. Fox-1Cliff and Fox-1D are scheduled to launch soon.

The RadFxSat-2 spacecraft bus will be built on the Fox-1 series but will feature a linear transponder upgrade to replace the standard FM transponder used in Fox-1A through Fox-1D. In addition, the uplink and down- link bands will be reversed from the previous Fox satellites in a Mode V/U (J). The downlink will feature a 1200 bps BPSK telemetry channel to carry the Vanderbilt science data in addition to a 30-kHz wide transponder for Amateur Radio use. — Thanks to Paul Stoetzer, N8HM; ULA; AMSAT News Service

Product Announcement DXtreme Monitor Log 11™

Fri, 11/17/2017 - 08:57

DXtreme Software™ has released a new version of its popular logging program for radio monitoring enthusiasts: DXtreme Monitor Log 11.
Monitor Log 11 lets listeners and DXers log the stations they’ve heard using advanced
features that can enhance their monitoring experience.

Finding Broadcast Stations to Monitor

The Schedule Checker™ lets users import schedules from Aoki, EiBi, and FCC AM
web sites and display schedule data according to the filter criteria they specify. A list
box lets users switch between schedule types, and depending on the schedule type
selected, users can filter schedule information by band, frequency, station, country,
city, state, time of day, language, antenna direction, and target area.
When the What’s On Now? function is activated, the schedule refreshes automatically at the top of each hour for Aoki and EiBi schedules.

For each schedule item, Schedule Checker queries the Monitor Log 11 database to
let users know – through user-defined, foreground and background display colors –
whether they need to monitor a station for a brand-new or verified country. Schedule
Checker also displays bearing and distance, runs optional Afreet Ham CAP1
propagation predictions, draws optional Afreet DX Atlas2 azimuth plots, tunes
supported radios to schedule frequencies when users double-click schedule items3 4 5,and starts log entries for scheduled stations monitored.

Finding Amateur Radio Stations to Monitor
Monitor Log 11 integrates with optional Afreet Band Master6
to let users see, on its
graphical interface, where hams are operating. Monitor Log 11 supplies Band Master
with an Entity Needed List based on the user’s Monitor Log database, making it
possible for Band Master to indicate the stations whose entities (countries) users
need to monitor. When invoking Band Master, users can select an Entity Needed List
for all bands or individually for the 160- through 6-Meter bands.

Finding Utility Stations to Monitor

A Links menu provides convenient access to user-specified blogs and web sites that
can inform users as to where utility and other stations may be operating.
Logging Stations
Monitor Log 11 lets users log all kinds of stations — radio stations, television stations,
broadcast stations, Amateur Radio stations, utility stations, military stations, and more!

And it lets them log stations across the radio spectrum — from long wave, to medium
wave, to short wave, and beyond.
The Last Log Entries Grid on the Monitor Log window shows up to 5000 of the most
recent log entries added. Its records can be sorted, and double-clicking records
displays detailed data on the Monitor Log window. Users can resize the grid columns
and scroll horizontally to columns that do not appear initially. And because the names of stations and NASWA countries can be quite long, users can also display a larger, resizable Last Log Entries window. A Properties window lets users change the
order of columns, the number of log entries to display, and the font and color attributesof grids and other program components, such as the Content Editor for describing the content monitored, the Script Editor for creating and editing scripts, the Direct Tuneinterface for tuning radios, and the Comments tab for typing ad hoc comments.

2 Reporting Reception
Users can create customized paper and e-mail reception reports for sending to
stations plus club report entries for reporting catches to clubs and magazines.
When users add or display a log entry, Monitor Log 11 prepares a post announcing
their DX catch and displays it on the Social Media Post tab. From there, users can
drag the post to their favorite social media web sites to share their catch with others.
Using the Script Editor window, users can create and edit scripts that format
reception reports, eReports, and social media posts to their liking. The software
prompts users to select the script they want to use. Dozens of scripts come with
Monitor Log 11.
Users can also print SWL and Address labels on industry-standard label stock, and
send eQSL requests to hams automatically through the popular www.eQSL.cc site.
Imaging
Improv Imaging™ lets users associate ad hoc images with log entries using Capture,
Scan, and Clipboard functions. Captures of stations received on digital applications,
waterfall displays, facsimile and Amateur TV pictures are popular. The Improv
Imaging tab and Application let users view images anytime, and an Improv Image
Explorer lets them peruse their entire collection and display associated log entries.
QSL Imaging™ functions the same as Improv Imaging, but specializes in associating
QSL cards and eQSLs with log entries.
Other Features
Rig Control — Retrieves the frequency and mode from supported radios and permits
tuning from the Schedule Checker and Direct Tune interface. Rig control is provided
through integration with Afreet Omni-Rig and the SDR applications listed on our web
site, currently HDSDR4
(High Definition Software Defined Radio) and SDR Console 5.

Hamfest 2017 – Preview of the Icom IC-7610 and IC-R8600 rigs

Fri, 11/17/2017 - 08:32

In part one of our reports from Hamfest 2017 we have a sneak preview of the Icom IC-7610 and IC-R8600 rigs. We meet the new owners of PW Magazine, and Pete tries his hand at the RSGB on-line exam. There’s also an update on the Society’s EMC Committee’s findings. Bob finds his way back to New Broadcasting House in London where the Director General discovers he has amateurs working for the Corporation. Nevertheless, Lord Hall broadcasts from the shack of the newly resurrected club station G8BBC. And, Laurie Margolis G3UML recounts an historic QSO he had from the early 1980s.

Radio Amateurs in Colombia, Germany Get New or Expanded Bands

Thu, 11/16/2017 - 13:43

Radio amateurs in Colombia have been granted new allocations at 60, 630, and 2200 meters. The new allocations resulted from the efforts of the Liga Colombiana de Radioaficionados (LCRA) — with the support of its “strategic partner” Liga Radio Bogotá (LRB). Access to the new bands will be effective when the Colombian Communications Ministry grants the privileges by administrative act. The new allocations are 135.7-137.8 kHz (2200 meters); 472-479 kHz (630 meters); and 5,351.5-5,366.5 kHz (60 meters).

In Germany, radio amateurs there now have a 60-meter band plus an extended 6-meter band, the Deutscher Amateur Radio Club (DARC) reports. Amateur radio has been allocated the band 5,351.5-5,366.5 kHz at a maximum power of 15 W EIRP on a secondary basis. This is in accordance with the allocation agreed upon at World Radiocommunication Conference 2015 (WRC 15). In addition, hams now have access to a slightly expanded 6-meter band. The band 50.08-51.0 MHz previously allocated to the amateur radio service on a secondary basis will be expanded to 50.03-51.0 MHz at a maximum 25 W ERP

Microwavers Report Successful US-Canada Contacts on 78 GHz

Wed, 11/15/2017 - 12:14

Microwave enthusiast Mike Seguin, N1JEZ, has reported several successful 78-GHz contacts between the US and Canada on November 9.

“We believe these contacts may be the first W/VE on 78 GHz,” Seguin said in a post to several VHF/UHF/microwave-oriented reflectors. “We hope to extend distances before winter sets in here in the Northeast and mountaintop access is limited.”

On the Canadian side were Rene Barbeau, VE2UG, and Ray Perrin, VE3FN. On the US side were Henry Ingwersen, KT1J, and Seguin. The first contacts were between FN35ja and FN34jx — a distance of 5 kilometers (3.1 miles), “primarily to tests systems,” Seguin said. “Contacts were easily made in SSB with huge signals on both ends.”

Next, N1JEZ and KT1J moved to FN34lt — extending the distance to 27 kilometers (16.7 miles), and again easily made contact with the Canadian crew. — Thanks to Mike Seguin, N1JEZ

Hytera & Siemens shake hands

Wed, 11/15/2017 - 08:22

Hytera, a leading global provider of innovative Professional Mobile Radio (PMR) communications solutions, and Siemens Limited China (Siemens) signed an agreement on comprehensive and sustainable strategic cooperation in Industry 4.0, Lean Production, and Intelligent Manufacturing during the 19th Session of China International Industry Fair in Shanghai on November 7th, 2017. The document was signed by Zeng Hua, Senior VP of Hytera, and Wang Haibin, Executive VP & General Manager of Digital Factory Division, Siemens. According to the agreement, Hytera will build a“Hytera-Siemens Industry 4.0 Intelligent Production Showroom”at its industrial park in collaboration with Siemens. 

 

Mr. Zeng Hua, Senior VP of Hytera, and Mr. Wang Haibin, Executive VP of Siemens, signing the strategic

According to the agreement, Hytera will be provided with consultation upon top-level design for digitalization, product lifecycle management (PLM) software and complete automation solution by Siemens. “All the time, we have insisted on implementing intelligent production vision, and improving manufacturing capability and management in our global Manufacture Centre in Shenzhen, as we believe advanced techniques and excellent quality can make us more competitive in the worldwide market. The strategic cooperation with Siemens will help improve our intelligent decision and operation efficiency in R&D, design, manufacturing and service, and therefore we are able to deliver a better customer experience,” said Mr. Zeng Hua, Senior VP of Hytera, at the strategic agreement signing ceremony. 

 

“Siemens is the only enterprise that can provide ‘The Digital Twin’ on the complete value chain from the process of product development and manufacturing to factory management. We have built up a number of examples of digitization enterprises with Chinese companies from automotive, electronics, food & beverage, textile fabrics, equipment manufacturing, pharmacy and steel sectors,” said Wang Haibin, Executive VP & General Manager of Digital Factory Division at Siemens, “The cooperation with Hytera will be another achievement that we help local enterprise complete digital transformation.”

 

Hytera iHPS Strategy  

Early in 2013, Hytera came up with the “Intelligent Hytera Production System” (iHPS) strategy and blueprinted a digitalized factory taking a series of actions like optimizing the production environment and process, automatizing test and assembly, eliminating manufacturing weakness to move towards manufacturing intelligentialization. The iHPS strategy has indicated the future and direction of Hytera High-tech Manufacture Centre and can be interpreted further in details as Hytera’s aspiration for excellence and perfection. With continuous investment in automation and informatization in the upcoming future, Hytera will build up a worldwide prestigious PMR industrial base.

The core of the intelligent manufacturing is to connect and utilize the data from market demand, research and development and production. Based on the above consideration, Hytera brings in the Siemens PLM solution as its informatization platform of intelligent manufacturing and cooperates with Siemens, a world-class practitioner and supplier and key player of Industry 4.0, to further improve its performance in a number of fields like team collaboration, project management, project delivery, product development and manufacturing, product properties and quality.

Announcing the new RSP1A wideband full featured 14-bit SDR

Wed, 11/15/2017 - 07:47

 

The SDR-play RSP1A is a major upgrade to the
popular RSP1—it is a powerful wideband full
featured 14-bit SDR which covers the RF spectrum
from 1kHz to 2GHz. All it needs is a PC and an
antenna to provide excellent communications
receiver functionality. Combined with the power of
readily available SDR receiver software (including
‘SDRuno’ supplied by SDRplay) you can monitor up
to 10MHz of spectrum at a time. Documented API
allows developers to create new demodulators or
applications around the platform.

SDRplay announces the RSP1A

SDRplay Limited has today announced the launch of a new Software Defined Radio product – the RSP1A.

The SDR-play RSP1A is a major upgrade to the popular RSP1 and is a powerful wideband full featured 14-bit SDR which covers the RF spectrum from 1 kHz to 2 GHz.

Due to its exceptional combination of performance and price, the RSP1 has proved to be a very popular choice as an “entry level” SDR receiver. Since launching the RSP1, we have learned a great deal about what people are looking for in SDR receivers, and where possible, we have incorporated these improvements and new features into the RSP1A.

The RSP1A therefore delivers a significant number of additional features which result in benefits to amateur radio enthusiasts as well as significant benefits for the scientific, educational and industrial SDR community.

Here are the main additional features of the RSP1A compared to the original RSP1:

  • ADC resolution increased to 14-bit native for sample rates below 6 MHz, increasing to 16 bits with decimation.
  • Enhanced RF pre-selection (greater filter selectivity plus 4 additional sub-bands compared to the original RSP1) for reduced levels of spurious responses
  • Improved LNA architecture with variable gain. The RSP1 had just a single gain step.
  • Improved intermodulation performance • Performance extended to cover 1kHz to 2 GHz with a single antenna port.
  • Bias-T facility • Improved frequency stability incorporating a 0.5ppm TCXO (software trimmable to 0.01ppm)
  • Selectable broadcast AM/FM/DAB notch filters
  • RF shielding within the robust plastic casing

When used together SDRplay’s own SDRuno software, the RSP1A becomes a high performance SDR platform. The benefits of using the RSP1A with SDRuno include:

  • Highly integrated native support for the RSP1A
  • Calibrated RF Power Meter with more than 100 dB of usable range
  • Calibrated S-Meter including support for IARU S-Meter Standard
  • The ability to save power (dBm) and SNR (dB) measurements over time, to a CSV file for future analysis
  • The IQ output wav files can be accessed for 3rd party applications

SDRplay has also worked with developers of the popular HDSDR, SDR-Console and Cubic SDR software packages to ensure compatibility. As with the RSP1, SDRplay provides multiplatform driver and API support which includes Windows, Linux, Mac, Android and Raspberry Pi 3. There is even a downloadable SD card image available for Raspberry Pi3 which includes Cubic SDR.

The RSP1A is expected to retail at approximately £76 (excluding taxes) or $100 (excluding taxes)

For more information visit our website on www.sdrplay.com

About SDRplay:

SDRplay limited is a UK company and consists of a small group of engineers with strong connections to the UK Wireless semiconductor industry. SDRplay announced its first product, the RSP1 in August 2014

US Court of Appeals Upholds Dismissal of Lawsuit in Ames v ARRL Case

Tue, 11/14/2017 - 17:11

A lawsuit filed by former ARRL Eastern Pennsylvania Section Manager Joseph Ames, W3JY, of Malvern, Pennsylvania, against ARRL and several of its officers and Board members was dismissed with prejudice by the United States District Court in Philadelphia in December 2016.

Ames filed an appeal of that decision, and on November 11, the United States Court of Appeals for the Third Circuit upheld the lower court’s dismissal of the suit.

In its opinion, the appellate court wrote, “because the record shows that Ames acted contrary to [an] August 2015 directive on at least two occasions, the [ARRL’s] statement that Ames ‘repeatedly acted contrary’ to the directive is true and cannot support a claim for defamation…it is apparent on the face of the complaint and related documents that the statements in the [ARRL website news] article are true, and the District Court therefore correctly held that the defendants established a complete defense to Ames’s defamation claim and appropriately dismissed the complaint.”

In June 2016, the Executive Committee of the ARRL Board of Directors relieved Ames of his appointments in the ARRL Field Organization, including his position as Chairman of the ARRL National Traffic System™ (NTS™) Eastern Area.

All WX Solar Powered Amateur Radio Field Station

Tue, 11/14/2017 - 05:47

 

“In today’s video I’d like to discuss the concept of a solar-powered field station for amateur radio emergency communications. Those of you who follow the blog, probably already know about this project. For the rest of you here is a video introduction of a concept I call the All WX Solar-Powered EMCOMM Field Station. The concept for a rapidly deployable,  man-portable field station, came to me after the grid down disaster caused by Hurricane Maria. Hurricane Maria knocked out electricity and communications throughout most of the affected area, leaving hospitals in cities and distant regions, without reliable communications between them. I’m under No Illusion about amateur radios ability to completely replace network communications. However, amateur radio can provide essential Communications between hospitals and health centers, pass well & safe traffic, or create HF datanet to manage amateur radio operator resources and logistics, while no other communication services exist. – The station is powered by a PowerFilm Solar FM16-7200 thin film solar panel. – The Tent Shelter is a next gen Nortent Tipi 6 hot tipi ( teepee ) tent. The article is work-in-progress, so it will certainly adapt and change as it becomes more mature. The goals are there, and the ideas are solid. Please do join the discussion.
