The K7RA Solar Update

Fri, 09/25/2020 - 09:12

Tad Cook, K7RA, Seattle, reports: Up until September 23, we saw 32 consecutive days with no sunspots. Then new sunspot group AR2773 appeared, which has a magnetic signature indicating it’s part of new Solar Cycle 25. Spaceweather.com noted it was a weak one, and may not persist for long. The daily sunspot number for September 23 was 13, indicating three sunspots visible in that group, but the sunspot was gone the next day.

Average daily solar flux rose from 69.2 to 71.1 over the September 17 – 23 reporting week. Geomagnetic indicators were about the same, with average daily planetary A index declining from 5.3 to 5.1.

As of September 23, the predicted solar flux for the following 45 days was 73 on September 24 – October 1, and 70 on October 2 – November 2.

The next day that forecast was revised to a predicted solar flux of 70 on every day until November 8. But on Thursday, September 24, the solar flux was 73.6, closely matching the previous day’s forecast.

Predicted planetary A index is 15, 12, 25, and 15 on September 25 – 28; 8 on September 29 – 30; 5 on October 1 – 10; 10 on October 11; 5 on October 12 – 19; 10, 12, 16, 28, 18, and 10 on October 20 – 25; 5 on October 26 – November 6; 10 on November 7;and back to 5 on November 8.

Here’s the geomagnetic activity forecast for September 25 – October 20, from F.K. Janda, OK1HH.

The geomagnetic field will be:

  • quiet on October 6 – 7
  • quiet to unsettled on October 5, 8 – 9, 13 – 16, 18
  • quiet to active on September 30, October 1 – 2, (3 – 4, 10, 12, 17), 19
  • unsettled to active September 25 – 26, 28 – 29, (October 11, 20)
  • active to disturbed (September 27)
  • Solar wind will intensify on September (27 – 28,) 29 – 30, October 1, 13 – 14, (15, 21,) 22

Note: Parentheses mean lower probability of activity enhancement.

The OK1HH forecast sees active to disturbed conditions on September 27, which matches the NOAA and USAF A index prediction of 25 on that date. This disturbance returns about 30 days later with an A index of 28 on October 23.

An interesting article in SciTechDaily discusses, “How NASA & Scientists around the World Track the Solar Cycle.”

Ken, N4SO, on the Alabama Gulf Coast reports that he hears three 15-meter beacons daily on 21.150 MHz — LU4AA in Argentina, OA4B in Peru, and YV5B in Venezuela. These are part of the NCDXF beacon network, and he rarely hears the 1-W transmission. At the other power levels they are S-3 – S-4.

Here’s a recent video from Tamitha Skov, WX6SWW, the “Space Weather Woman.”

Sunspot numbers for September 17 – 23 were 0, 0, 0, 0, 0, 0, and 13, with a mean of 1.9. The 10.7-centimeter flux was 69.7, 69.9, 70.6, 70.2, 71.3, 72.4, and 73.3, with a mean of 71.1. Estimated planetary A indices were 4, 5, 3, 4, 3, 6, and 11, with a mean of 5.1. Middle latitude A index was 5, 4, 4, 4, 3, 5, and 10, with a mean of 5.

Hams Help Find Kids by Monitoring FRS Radios

Thu, 09/24/2020 - 12:37

Late on the afternoon of September 16, the police department in Post Falls, Idaho, received a 911 call that two juveniles — ages 9 and 11 — were missing from a Post Falls residence for about an hour. According to the report, the pair had left home intending to play in the neighborhood with some Family Radio Service (FRS) radios. Several patrol cars were dispatched to the area to conduct a visual search, and detective Neil Uhrig, K7NJU, responded as officer in charge due to his training and experience with missing persons investigations. The initial search focused on a 2-mile radius from the missing kids’ residence.

One officer received information from witnesses that the pair was probably using FRS Channel 1 (462.5625 MHz). An officer returned to police headquarters to retrieve some FRS radios for distribution to the patrol officers, in the event they might be able to hear the youngsters talking.

Uhrig, meanwhile, pulled out his VHF/UHF handheld with the thought of setting up FRS Channel 1 as an auxiliary frequency, but without the manual at hand, he wasn’t able to execute the channel setup. But Uhrig did hear the Northwest Traffic Net (NWTN) that had begun at 6:30 PM on the local 2-meter repeater.

Checking into the net at about 6:45 PM, Uhrig explained the missing persons situation to net control station Shannon Riley, KJ7MUA, and asked if net participants in the Post Falls area with FRS capability could listen for the youngsters talking.

A number of stations promptly checked in to say they had FRS radios and were monitoring FRS Channel 1. It was assumed that only stations located near the missing youngsters would hear them, given the limited range of FRS radios.

Not long after 7 PM, Jim Hager, KJ7OTD, reported hearing children talking on FRS Channel 1. Uhrig went to Hager’s home to confirm his observation, and the patrol units were redirected to the new search vicinity. A short time later, the missing pair was found safe and returned home.

Uhrig said the most remarkable thing about the incident was that the missing youngsters were some distance from the original search area, and in the opposite direction from where it was expected they might have been headed.

Net Manager Gabbee Perry, KE7ADN, said, “I’m so proud of what a superior job NWTN NCS Shannon and all the operators did last Wednesday. It was a very unusual situation, but everyone had excellent focus and used their resourcefulness to help quickly find the missing kids.” — Thanks to ARRL Assistant Idaho Section Manager Ed Stuckey, AI7H

Abbree Foldable CS Tactical Antenna

Thu, 09/24/2020 - 07:55

“I was looking for an antenna to throw in my camping kit to give the portable radio a little more range. Typically campsites and backwoods locations tend to be RF challenged, so I wanted something for my Yaesu FT-3DR to pick up area repeaters and APRS traffic without having to hoist up a larger base antenna. With that in mind, enter the Abbree foldable CS tactical antenna.”

International Telecommunication Union Releases 2020 ITU Radio Regulations

Thu, 09/24/2020 - 07:45

The International Telecommunication Union (ITU) has published the 2020 ITU Radio Regulations — the international treaty governing the global use of RF spectrum and satellite orbits. The publication contains the complete texts of the Radio Regulations adopted during World Radiocommunication Conference 2019 (WRC-19), held last year in Sharm el-Sheikh, Egypt. Available in all six of ITU’s official languages, the 2020 ITU Radio Regulations are in effect for all signatory parties on January 1, 2021. Electronic versions are free, and the “traditional four-volume boxed set,” as well as a multilingual DVD, will be available for purchase in the coming weeks, the ITU said.

“The publication of the Radio Regulations is the culmination of the hard work and intense deliberations that took place during WRC-19,” said ITU Secretary-General Houlin Zhao. “Efficient and economical use of the naturally limited radio-frequency spectrum is key to ensuring we bring the benefits of connectivity and digital transformation to people everywhere. The ITU Radio Regulations are a vital vehicle for this endeavor.”

The ITU said that, when it comes to allocating radio frequencies, including sharing and harmonizing their use for different purposes, the Radio Regulations are the ultimate tool. “They ensure the use of the RF spectrum is rational, equitable, efficient, and economical, all while aiming to prevent harmful interference between different radio services,” the ITU said.

The ITU Radio Regulations also play an important role in promoting access to affordable broadband for all, the ITU said. The Radio Regulations govern 40 radiocommunication services, and are designed to protect existing radio services while enabling the introduction of new and enhanced services.

New mode FST4 – WSJT-X

Wed, 09/23/2020 - 13:12

Steve Franke, K9AN; Bill Somerville, G4WJS; and Joe Taylor, K1JT

Version 2.3 of WSJT-X introduces a new family of digital modes we designate FST41
. These modes
have a wide range of capabilities and potential applications. Their fundamental sensitivities are better
than most older modes in WSJT-X and are close to the theoretical limits for the same information
throughput rates. Particular target applications include
WSPR-like, quasi-beacon transmissions on LF and MF bands
QSOs with very weak signals on the LF and MF bands
EME on VHF and UHF bands with T/R sequences both shorter and longer than 60 s
… but other uses will surely be found, as well. We expect that FST4 will serve some of its intended
purposes better than older modes in WSJT-X, and without the strict time- and frequency-locking
requirements of modes such as EbNaut.
FST4 uses 4-GFSK modulation and offers T/R sequence lengths of 15, 30, 60, 120, 300, 900, and 1800
s. Submodes A, B, C, and D provide different tone spacings, to allow for use with a variety of propagation types and Doppler spreads. Forward error correction uses a low density parity check (LDPC) code with 240 information and parity bits. Transmissions consist of a sequence of 120
information-carrying symbols (2 bits each) interspersed with 40 synchronizing symbols. The underlying message payloads contain either 77 bits (the standard payload for FT4, FT8, and MSK144) or 50 bits (the standard for quasi-beacon, WSPR-style messages). With WSPR-like messages the mode
designation becomes FST4W and the A submode is always used. In all cases, message formats
displayed to the user are the same as in the other 50-bit and 77-bit modes in WSJT-X.

Basic parameters of the A submodes are given in the following table. The measured sensitivities are based on simulations on the additive white Gaussian noise (AWGN) channel, and depend on oscillator
drifts and path Doppler spreads being smaller than the tone spacing over the full transmission length.

  1. Do not confuse FST4 with FT4 — a digital mode with 7.5 s T/R sequences designed for HF and VHF contesting.
    Submodes are given full names like FST4-60A, where 60 indicates 60-second sequences and A impliesminimum tone spacing. Submodes B, C, and D have larger tone spacings and occupied bandwidths by factors of 2, 4, and 8, respectively. Sensitivities of the wider submodes are degraded by amounts that depend on Doppler spread and other details of the propagation path. As with other recently developed
    modes in WSJT-X, a feature called a priori (AP) decoding improves sensitivity by several additional dB as information accumulates during a standard minimal QSO.
    Suggested test applications for some of the FST4 and FST4W submodes include the following:
  2. FST4W-120A, -300A, -900A, -1800A WSPR-like transmissions on the 630 and 2200 m bands
  3. FST4-120A, -300A, … QSOs on the 630 and 2200 m bands
  4. FST4-15A Ionospheric scatter (mid-day is best) on 50 MHz
  5. FST4-15A, -30B, -30C, -30D Fast (contest?) EME QSOs on 144 – 1296 MHz ?
  6. FST4-120B, -120C, -300C, -300D EME on 50, 144, 432 MHz with weakest possible signals
    Many other combinations are possible, and users will surely think of some we have not considered. As
    just one example: VK7MO and VK7ZBX have had good success with non-line-of-sight optical
    scattering communication over obstructed paths as long as 43 km, using LED arrays and FST4W.
    Operators familiar with WSJT-X will find using the FST4 modes straightforward, so we touch here only
    on a few differences. The decoder searches for decodable signals only within the selected F Tol rangeeither side of Rx Freq. We suggest operating with File → Settings → General → Single decode
    checked. (Note, however, that if more than one signal is present multiple decodes can occur within the F Tol range.) Other on-screen controls including Auto Seq behave as expected in other WSJT-X modes.
    For EME, be sure to check the options Enable VHF and submode features and Decode after EME delay. Doppler tracking for the EME path is accomplished in the same way as with other WSJT-X modes.
    To see the presently suggested default FST4 and FST4W frequencies in the drop-down band-change
    control you may need to do a one-time reset. Go to File → Settings → Frequencies, then right-click on
    the Working Frequencies table and select Reset.
    FST4W behaves in most ways like the familiar WSPR mode. Sequence lengths of 120, 300, 900, and
    1800 s are available. Rx Freq is always set to 1500 Hz and F Tol to 100, so the active FST4W range is
    1400 to 1600 Hz. A new drop-down control just under the one for T/R sequence lengths provides a
    round robin mode for scheduling transmissions (see Figure 1). If three operators agree in advance to
    select the options 1/3, 2/3, and 3/3, their FST4W transmissions will occur in fixed sequence with no two
    stations transmitting at once. Sequence 1 is the first sequence after 00:00:00 UTC. For WSPR-like
    scheduling behavior, select Random.
    Optional noise blanking is available and appears to be effective in handling typical atmospheric noise on
    LF and MF bands. A spinner control labeled NB nn % is located on the FST4 and FST4W main
    window, just below the band-change control. Set this control to a suggested percentage of data samples
    to be blanked. We have found that levels in the 10 – 15% range work well in summer conditions on LF/
    MF bands, but you will probably want to experiment. Data displayed on the waterfall and saved to .wav
    files do not have blanking applied.
    Figure 1: Controls for “Round Robin” scheduling and other features for FST4W mode.
    As an example of capabilities of the new modes, Figure 2 shows decodes of FST4W-300A signals received on the 2200 m band at NO3M on July 23, 2020. The weakest of these signals are close to the decoding threshold for this submode, SNR = -35 dB. Numbers at the end of each decoded line aremeasurements of path Doppler spread in Hz. To activate this feature, create a file named plotspec in the current working directory and start WSJT-X from the command line there. As a general rule, decoding requires Doppler spreads less than the submode tone spacing. Sensitivity is best when Doppler pread is no more than 1/8 of the tone spacing.
    As with other modes in WSJT-X, our development of FST4 started by coding a simulator to generate Signals in any of the submodes with specified SNR, Doppler spread, and multi-path delays. The simulator is called fst4sim, and is part of the test distribution package. Feel free to use it for your own tests.In early testing we will appreciate your detailed feedback on both successes and failures. The FST4 decoder makes internal adaptations that depend on the degree of coherence found in received signals. Final optimizations will depend on having representative recordings of signals in propagation conditions
    of particular interest. Please use Save All or Save Decoded and preserve the recorded .wav files for laterstudy.
    Members of the initial test group fall in two broad and overlapping categories according to current
    interests known to us, as follows:
    LF and MF: 2E0ILY KA1R K3MF K3RWR N1BUG N6LF NO3M VK4YB W1VD W7IUV
    EME: G3WDG HB9Q K3MF K5DOG KA1GT PA2V VK4EME VK7MO W2HRO
    Many useful tests will need pre-arrangement by two or more group members. Among our highest
    priority needs are saved .wav files from two-way QSOs over significant distances on the 2200 and 630 m
    bands, and decodable EME signals on all bands — but especially 50, 144, 432, and 1296 MHz, where
    FST4 is likely to be most useful SOURCE:LINK

80th Anniversary of the Battle of Britain

Wed, 09/23/2020 - 07:11

Special Event Station GB80BOB

1st September to 28th September 2020

The Royal Air Force Amateur Radio Society (RAFARS) will be operating a Special Event Station (SES) from 1st September to 28th September 2020 to commemorate the Battle of Britain. 2020 marks the 80th anniversary of the Battle of Britain which took place between July and October 1940.

The 15th September 1940 was officially named Battle of Britain Day as it was the day when RAF Fighter Command claimed what proved to be a decisive victory over the German Luftwaffe.

Due to the prevailing circumstances Ofcom have relaxed their rules for SES’s and are allowing this call to be operated from a home QTH. This SE callsign will be allocated to RAFARS members and a list of operators and postcode locations will be displayed on the RAFARS website.

FT8 HEAVYWEIGHTS by 9Z4Y & KC0BRA

Tue, 09/22/2020 - 12:16

FT8 HEAVYWEIGHTS is an unofficial FT8 Special Event which… can be considered
simply an FT8 Sked meet, it was first conceptualized in December 2019 a week before Christmas day,
and launched on the First Saturday after Christmas,
invitations were sent out to a lot of EXOTIC DXCCs and we were joined by over 75% of the
invitations sent out due to the last minuete time frame… some of them are J69DS, J35X, 9Y4D,
9Y4DG, 3G3G, VP8NO, TR8CA, VP2ETE, E51BQ, ZS6C to name a few
we met on non standard FT8 Frequencies for example 14.064, 7.064 etc,

WE DO NOT USE F/H mode or Multi Streaming in this event
and in 2020 with keeping that tradition will be no different, we do expect your best operating practice,
if you have been looking for some Exotic DXCCs in your FT8 quest,
then FT8 HEAVYWEIGHTS is for you, get DX stations in one place to work!!!!!
ALL ARE WELCOMED TO JOIN,
if you are interested to join by yourself or with a few other friends in your country
please feel free to contact me for more details on time and best bands to suit you, at 9Z4Y@gmx.com
I am also asking to please help spread the word to make this year’s FT8 HEAVYWEIGHTS
even bigger and better than last year,
Thank you and see you guys soon
Stay safe, 73
Mark de 9Z4Y

Venerable AO-7 Satellite Approaching a Return to Full Solar Illumination

Tue, 09/22/2020 - 11:35

AMSAT-OSCAR 7 (AO-7), the oldest amateur radio satellite still in operation, is nearing a return to full illumination by the sun, which should take place around September 25 and continue until around December 26. AMSAT’s vice president of operations Drew Glasbrenner, KO4MA, says that during this period, AO-7 likely will switch between modes A (2 meters up/10 meters down) and B (70 centimeters up/2 meters down) every 24 hours. He reminded users to use only the minimum necessary power and to avoid “ditting” to find their signals in the passband, which can bounce the entire passband up and down and sometimes even cause the transponder to reset to mode A.

“Try to find yourself with very low power, or on SSB, or best, with full Doppler control,” Glasbrenner said. “If you have to use high power to find yourself, your receive antenna and system probably needs improvement.”

Last May, the nearly 46-year-old AO-7 made possible a contact between Argentina and South Africa — a distance of more than 4,300 miles. Both stations were aiming just 2° or 3° above the horizon. AO-7 only works when it’s receiving direct sunlight and shuts down when in eclipse.

Launched in 1974, AO-7 surprised the amateur satellite community by suddenly coming back to life in 2002 after being dormant for nearly 30 years and periodically re-emerging. AMSAT considers AO-7 “semi-operational.” Theory is that AO-7 initially went dark after several years of operation when a battery shorted, and it returned to operation when the short circuit opened. With no working batteries, AO-7 now only functions when it’s receiving direct sunlight, and it shuts down when in eclipse.

Built by a multinational team under AMSAT’s direction, AO-7 carries a non-inverting Mode A transponder (145.850 – 950 MHz up/29.400 – 500 MHz down) and an inverting Mode B (432.180 – 120 MHz up/145.920 – 980 MHz down) linear transponder. It has beacons on 29.502 and 145.975 MHz, used in conjunction with Mode A and Mode B/C (low-power mode B), respectively. A 435.100 MHz beacon has an intermittent problem, switching between 400 mW and 10 mW.

New Japan RTTY sub-bands

Tue, 09/22/2020 - 08:31

Hide, JH8KYU/1, wants to remind everyone of the new JA RTTY sub-bands during the CQWW DX RTTY Contest (September 26-27th):

80m — 3520-3580 kHz 20m — 14070-14150 kHz
3599-3612 kHz 15m — 21070-21150 kHz
3662-3680 kHz 10m — 28070-28200 kHz
40m — 7030-7200 kHz

The highlight of the change this year is the expansion on 80m. They still cannot transmit on the main zone of 3580-3599 kHz, but 80m has been a little bit expanded compared to past years.

Hide, JH8KYU/1, states, “I will try to operate on 80m more often and hope to get more contacts than last year. See you on all bands including 80m in the coming WW contest.”

MARS Communications Exercise will Involve Amateur Radio Community

Mon, 09/21/2020 - 15:59

Military Auxiliary Radio System (MARS) volunteers will take part in the Department of Defense (DOD) Communications Exercise 20-4, starting on October 3 and concluding on October 26.

The MARS focus is interoperability with ARRL and the amateur radio community. “Throughout the month of October, MARS members will interoperate with various amateur radio organizations that will be conducting their annual simulated emergency tests with state, county, and local emergency management personnel,” said MARS Chief Paul English, WD8DBY.

“MARS members will send a DOD-approved message to the amateur radio organizations recognizing this cooperative interoperability effort.” MARS members will also train with the ARRL National Traffic System (NTS) and Radio Relay International (RRI) to send ICS 213 general messages to numerous amateur radio leaders across the US. “This exercise will culminate with MARS Auxiliarists sending a number of summary messages in support of a larger DOD communications exercise taking place October 20 – 26,” English added.

Throughout October, MARS stations will operate on 60 meters, and WWV/WWVH will broadcast messages to the amateur radio community. English assures no disruption to communications throughout the month-long series of training events.
