DATE 2020 May 31 To All RADIO AMATEURS BID: $ANS-152.01 Temporary Rule Waivers Announced for 2020 ARRL/AMSAT Field Days ARRL Programs and Services Committee (PSC) has adopted two temporary rule waivers for the 2020 ARRL Field Day to adjust for Covid-19 re- strictions. An AMSAT parallel event is held at the same time, and the rules for that have been adjusted, as well. ARRL Field Day is one of the biggest events on the amateur radio cal- endar, with over 36,000 participants in 2019, including entries from 3,113 radio clubs and emergency operations centers. In most years, Field Day is also the largest annual demonstration of ham radio, be- cause many radio clubs organize their participation in public places such as parks and schools. Due to the COVID-19 pandemic, many radio clubs have made decisions to cancel their group participation in ARRL Field Day this year due to public health recommendations and/or requirements, or to significantly modify their participation for safe social distancing practices. The temporary rule waivers allow greater flexibility in recognizing the value of individual and club participation regardless of entry class. The waivers may be found at: https://bit.ly/3de5AJt The Radio Amateur Satellite Corporation (AMSAT) promotes its own ver- sion of Field Day for operation via the amateur satellites, held con- currently with the ARRL event. The rules for the AMSAT Field Day may be found at: https://www.amsat.org/wordpress/wp-content/uploads/2020/05/2020fd.pdf This will mean that there will be another group of certificates for AMSAT Field Day: The top three stations operating from home with com- mercial power. The problem is with those operating from home attaching their scores to a club. Because AMSAT only allows one satellite station to be oper- ating at a time, if you are going to attach your satellite contact to a club, only ONE home station can attach per club. This will keep the playing field rather equal as there are areas where there is only one satellite op around and other areas where there are dozens of satellite ops. It would be unfair for an area with a dozen satellite ops to pool all their home contacts towards one club. Even if satellite operators took turns operating in shifts, it would make it very difficult to score entries correctly. That is why AMSAT has chosen to allow only one satellite home station could be attached to a single club. CLUB NAME MUST BE IDENTIFIED IN THE ENTRY. There will also be no duplicate certificates. If you are attaching your score to a club, then it goes towards club rankings and not home rankings. Nothing needs to be changed on the submission form. If you are operating 1D and the name of your attached club is included, the club score will be calculated appropriately. This is new and uncharted waters and hope everyone enjoys AMSAT Field Day. A much larger number of entries is anticipated with this change, so patience is appreciated.

They do NOT involve use of narrowband FM signals such as those used for terrestrial APRS or dedicated APRS satellites. So please, NEVER transmit FM on the uplink to a linear satellite. ALSO, in should be emphasized that power levels must be kept very low, as all the WSJT modes are 100% duty cycle.] Recently a group of regular satellite-using amateurs conducted experi- ments with FT-8 and FT-4 on a variety of linear satellites. Alan (WA6DNR), Carlos (W7QL), Dave (W0DHB) and Ron (W5RKN) were involved and made many satisfactory QSOs. The primary results and observations from these tests are: • Digital modes can successfully be employed on the linear birds while not interfering with concurrent users by operating close to the bottom end of the passband, using the lowest power practicable and using very narrow signals. • We avoided the satellites known to be power-sensitive, FO-29 and AO-7. Testing was conducted with CAS-4A, CAS-4B, RS-44, XW-2A, XW-2B, XW-2C and XW-2F. • FT-4 was the most robust signal format, compared to FT-8. Other of Joe Taylor’s digital signal modes should be investigated. • The rate of change of Doppler just before and after TCA is high on the lower-orbit satellites and must have compensation. 200 Milli- second Doppler updates allowed 100% copy of FT-4 transmissions throughout several passes of different linear satellites. This can be accomplished in SatPC32 by setting the “SSB/CW Interval” in the CAT menu to zero and checking the 5X box. Note that this setting is not retained when SatPC32 is shut down. • Very little power is needed for QSOs throughout the duration of the pass, from AOS to LOS. W7QL set IC-9700 power to “zero” (roughly 500 milli-Watts, with over 3 dB cable/connector loss to a Leo-Pack anten- na pair) and copied every packet on several satellites. • FT-4 is very tolerant of voice signals which might drop on top of an ongoing FT-4 QSO. However, an FT-4 signal dropping in the middle of an SSB QSO would be quite annoying to the SSB operators. • According to Joe Taylor, the occupied bandwidth of an FT-4 signal is 90 Hz. So theoretically over 200 such signals could be present on a 20 KHz channel. Obviously that will not, and should not happen. But a dozen closely spaced FT-4 QSOs at the bottom of the band, each run- ning very low power should hardly be noticeable to current voice and CW traffic. We invite other Satellite operators to join us in this expanded utili- zation of the linear satellite resources available to us. We recommend using FT-4 AT VERY LOW POWER, in the bottom few KHz of the downlink frequency range, with appropriate Doppler compensation, as described above. We hope to have a digital QSO with you sometime soon on the linear birds.

At 19:22 UTC they were successfully launched on their way to the International Space Station. This was the first launch of astro- nauts from U.S. territory since the final Space Shuttle flight in 2011 and the first launch of humans by a private contractor, SpaceX. The first attempt for the launch, on Wednesday, May 27, scrubbed due to stormy weather near the Kennedy Space Center in Florida. The Crew Dra- gon spacecraft is scheduled to dock with the ISS about 19 hours after liftoff.

The contact was made possible using the currently avail- able beta-release candidate of WSJT-X, version 2.2-rc1. "Why might you want to use FT8 instead of 'Old Reliable JT65' for EME QSOs?" Taylor asked in a subsequent Moon-Net post. "FT8 is about 4 dB less sensitive than JT65, but with 15-second T/R [transmit/receive] sequences it's four times faster, and it doesn't use Deep Search," he said, answering his own question. The FT8 protocol included in the beta version of WSJT-X has an optional user setting to work around the 2.5-second path delay. "For terrestrial use, the FT8 decoder searches over the range -2.5 to +2.4 seconds for clock offset DT between transmitting and receiving stations," Taylor explained. "DT" represents the difference between the transmission time and actual time. "When 'Decode after EME delay' is checked on the WSJT-X 'Settings' screen, the accessible DT range becomes -0.5 to +4.4 seconds. Just right for EME." As Taylor explained in his post, FT8 uses 8-GFSK modulation with tones separated by 6.25 Hz. At the time of the contact, the expected Doppler spread on the W2HRO - PA2V EME path was 8 Hz, which would cause some additional loss in sensitivity. Despite the path losses, however, copy between W2HRO and PA2V was "solid in both directions," Taylor said. Taylor said that when he was active in EME contests on 144 MHz, he was always frustrated that, even with reasonably strong signals, the max- imum JT65 contact rate is about 12 per hour. "With FT8, you can do 40 per hour, as long as workable stations are available," he said. As for using FT8 for EME contacts on 1296 MHz, Taylor said it "might sometimes work, but Doppler spread will probably make standard FT8 a problem." Given sufficient interest, however, he said the WSJT-X devel- opment team could design an FT8B or FT8C with wider tone spacing. He encouraged the use of FT8 for moonbounce on 144, 432, and 1296 MHz and asked users to report their results to the development team. "A 'slow FT8' mode is indeed a sensitivity winner on suitable propaga- tion paths," he said in a later Moon-Net post. "We are busy implement- ing such a mode, but with particular emphasis on its use on the LF and MF bands." Taylor said FT8 has the operational advantage of putting all users in one (or a few) narrow spectral slices on each band. "So, it's easy to find QSO partners without skeds or chat rooms," he said. "Everything is done over the air, with no 'side channels' needed." Taylor also remarked in response to posts from those who, like him, "love CW." "I agree it's a thrill to hear your own lunar echo, and to make CW EME QSOs," he said. "Sometimes I pine for the bygone world of commercial sailing ships, which happen to be very much a part of my family's his- tory," Taylor concluded. "But I know that technologies evolve, and the world does not stand still."

ARISS educator, Joanne Michaelis, KM6BWB, is a science coach at the Wiseburn Unified School District in Los Angeles, California where she leads her students in several balloon launch attempts from the Los Angeles area each year. With this year different because of the pan- demic, Joanne wanted to “shake things up a bit” and give students world-wide, a unique distance learning treat while keeping all safe during the pandemic. So Joanne challenged Ted Tagami, KK6UUQ, from Magnitude.io to a mid-altitude cross-continent balloon race and Ted accepted the challenge! Ted plans to launch his balloon from Oakland, California. ISS Above in- ventor, Liam Kennedy, KN6EQU, from Pasadena, California, got “wind” of the idea and he asked to participate, too. All three organizations: ARISS, Magnitude.io and ISS Above are ISS National Lab Space Station Explorer (SSE) partners that work to inspire, engage, and educate stu- dents in Science Technology Engineering, Arts and Mathematics (STEAM) topics and to pursue STEAM careers. The three SSE teams plan tolaunch their balloons simultaneously on June 1. The winner will be the first one to cross the“Finish Line”—the Eastern Time zone. Launch time is planned for 15:00 UTC (11:00 EDT, 10:00 CDT, 9:00 MDT, or 8:00 PDT. A live video feed of the launch is planned to start approximately 5 minutes prior to the event. Once the balloons are airborne, students can track each balloon’s loca- tion, altitude, and temperature via amateur radio APRS (Automatic Pac- ket Reporting System) which is fed automatically to the aprs.fi web site. Educators and parents around the globe can excite at-home youth withthis initiative. Students can tally and track the states each bal- loon travels through and plot altitude versus temperature, etc. Also, by researching weather patterns, students can make assumptions from their own data. This could include speed variations due to weather. They also can predict each balloon’s flight path and when they might cross the finish line!

They will be using the K5Z call sign. More information is available at the K5Z QRZ Page. FP, ST. PIERRE & MIQUELON (Rescheduled). Eric, KV1J, will once again be operating from the Island of Miquelon (NA-032, DIFO FP-002 WLOTA 1417, Grid GN17) as FP/KV1J between September 22nd and October 6th. This oper- ation was originally scheduled for July, but was postponed due to trav- el restrictions. It will be Eric’s 14th trip to the island. Activity will be on 160-10 meters, including 60m , using CW, SSB, RTTY, FT8/FT4 (but primarily SSB, RTTY and FT8/FT4) and the SSB/FM satellites. He will generally be on the highest frequency band that is open (favoring 60/12/10/6m). He will be active in the CQWW DX RTTY Contest (September 26-27). ADDED NOTE: Eric will usually try to be on as many Satellite passes as he can when the WX is good, generally favoring the XW-2x, AO-7, RS-44, CA-4x, and possibly the FM birds. Weekends may be limited since he will be concentrating on the low(er) bands and contests. QSL via KV1J, direct or by the Bureau. Also eQSL and LoTW.

Excellent QSO with AO-27
by Brian Wilkins KO4AQF 29 May '20

29 May '20

Just performed my first QSO on AO-27 with N5BO. Heard also CO8TW who also sounded excellent. I found it easier to work than SO-50. I did not hear (apologize for incorrect terminology), a carrier so I attempted to transmit while in TCA. N5BO came back when I transmitted. I do not know if I happened to hit the timer just right but it worked. From 0-30, heard nothing until I could hear myself immediately upon TX in full duplex. This was performed using a TH-D72A and Arrow II. I wouldn’t have been successful up to this point if it wasn’t for the AMSAT community at large. Thank you again for resurrecting this bird!

Updated Field Day Rules
by Bruce 29 May '20

29 May '20

I had mentioned in the AMSAT Field Day rules that we follow the ARRL rules to the most part except when it has to do with satellite operation. The ARRL has just updated the Field Day rules for this year and we will make accommodations as they have. Class 1D stations will now we allowed to contact other Class 1D stations. These are home stations operating on commercial power. This will mean that there will be another group of certificates for Field Day.... the top three stations operating from home with commercial power. The problem I see with those operating from home attaching their scores to a club is that we only allow one satellite station to be operating at a time. If you are going to attach your satellite contact to a club, I will have to have the name of the club and only ONE home station can attach per club. This will keep the playing field rather equal as there are areas where there is only one satellite op around and other areas where there are dozens of satellite ops. It would be unfair for an area with a dozen satellite ops to pool all their home contacts towards one club. I understand that one satellite op might work from noon to 2PM and another satellite op at their home could take over and work from 2PM to 4PM and yet another take over and work another shift, etc. This would make it very difficult for me to score. That is why I chose only one satellite home station could be attached to a single club. There will also be no duplicate certificates. If you are attaching your score to a club, then it goes towards club rankings and not home rankings. Nothing needs to be changed on the submission form, I will see if you are operating 1D and I will see the name of your attached club if any. This is new and uncharted waters and hope everyone enjoys AMSAT Field Day. I suspect that this year with the rule change there will be way more than the normal 20 submissions. Below is the release from the ARRL. 73...bruce With one month to go before 2020 ARRL Field Day, June 27 – 28, the ARRL Programs and Services Committee (PSC) has adopted two temporary rule waivers for the event: 1) For Field Day 2020 only, Class D stations may work all other Field Day stations, including other Class D stations, for points. Field Day rule 4.6 defines Class D stations as “Home stations,” including stations operating from permanent or licensed station locations using commercial power. Class D stations ordinarily may only count contacts made with Class A, B, C, E, and F Field Day stations, but the temporary rule waiver for 2020 allows Class D stations to count contacts with other Class D stations for QSO credit. 2) In addition, for 2020 only, an aggregate club score will be published, which will be the sum of all individual entries indicating a specific club (similar to the aggregate score totals used in ARRL affiliated club competitions). Ordinarily, club names are only published in the results for Class A and Class F entries, but the temporary rule waiver for 2020 allows participants from any Class to optionally include a single club name with their submitted results following Field Day. For example, if Podunk Hollow Radio Club members Becky, W1BXY, and Hiram, W1AW, both participate in 2020 Field Day — Hiram from his Class D home station, and Becky from her Class C mobile station — both can include the radio club’s name when reporting their individual results. The published results listing will include individual scores for Hiram and Becky, plus a combined score for all entries identified as Podunk Hollow Radio Club. The temporary rule waivers were adopted by the PSC on May 27, 2020. ARRL Field Day is one of the biggest events on the amateur radio calendar, with over 36,000 participants in 2019, including entries from 3,113 radio clubs and emergency operations centers. In most years, Field Day is also the largest annual demonstration of ham radio, because many radio clubs organize their participation in public places such as parks and schools. Due to the COVID-19 pandemic, many radio clubs have made decisions to cancel their group participation in ARRL Field Day this year due to public health recommendations and/or requirements, or to significantly modify their participation for safe social distancing practices. The temporary rule waivers allow greater flexibility in recognizing the value of individual and club participation regardless of entry class. ARRL is contacting logging program developers about the temporary rule waivers so developers can release updated versions of their software prior to Field Day weekend. Participants are reminded that the preferred method of submitting entries after Field Day is via the web applet. The ARRL Field Day rules include instructions for submitting entries after the event.
