PSAT2 status (GREAT NEWS!)
by Robert Bruninga 01 Jul '19

01 Jul '19

PSAT2 is doing great! PSK31 and SSTV transponder have been on since launch. SSTV downlinks are looking good. See Gallery: http://www.urel.feec.vutbr.cz/esl/psat2/sstv/ Still waiting for first report of user PSK31 contacts. But I have not said much about the VHF modes… because we have had difficulty commanding. This is because the PSAT2 VHF uplink uses an inexpensive narrowband XCVR module which is intolerant of overdeviated signals, exactly what you get with +/- 3 kHz of Doppler. ANYWAY, we can now consistently command if we set the Kenwood to narrowband NFM and do it right in the middle of the pass. Plus, we can extend that a bit (1.25 KHz after center) by then changing the radio step size to 6.25 Khz where the channel raster ups the channel by 1.25 KHz). So, we now have command again! You may have seen that we have turned on Sun vector S#... telemetry and can easily see by plotting the 1 minute xyz xyz xyz vector triplets that it is smoothly tumbling at about 1.3 RPM for nice battery charging and good thermal management. The downlink is live on FINDU: http://www.findu.com/cgi-bin/raw.cgi?call=psat2-1&time=1 Background: This last 6 days of crisis was complicated by the fact that I am operating in a temporary dungeon while the building is being renovated and all my 27 years of lab stuff is in 200 boxes surrounding me. I installed a temporary ground station on the top floor and modest antennas and a TV rotator and the contractor let me drill a hole through the wall that they can seal up later. But the big problem is the 8 flights of stairs from my PC and internet connectivity in the dungeon up to the radio 6 times a day for passes with only a few hours sleep and all kinds of what-if-dead-ends. And with passes from 10 PM to 2 AM. But we are back in the saddle again! And this good news reprieve is only an hour old, so it will take a while to decide what we want to do next. In any case, the Brno University PSK31 and SSTV transponder has all the power for now, so enjoy. Uplink USB on 29.4815 and downlink on 435.350 +/- Doppler. The transponder only comes up if there is a user in the uplink with PSK31. Bob, WB4APR

PSAT2 SSTV & PSK mixed
by Hans BX2ABT 01 Jul '19

01 Jul '19

Finally got a chance to tonight to see if I could get some signals in from PSAT2. Got a very nice image on a 58 degree pass (https://pbs.twimg.com/media/D-ZE3vHU4AE0Ah5.png), but I noticed it was intertwined with a PSK signal. Is that supposed to be? Got a stand-alone PSK signal a while later, but FLdigi couldn't decode it, because it looked like two separate PSK signal? How can you decode it then? (And yes, if the answer is out there accept my apologies: I have not been paying attention this past week. Sorry). 73 de Hans BX2ABT

Yaesu FT991A on the sats
by John Geiger 01 Jul '19

01 Jul '19

Has anyone used the Yaesu FT991A on the satellites? Does the bandscope really help to find people in the downlink passband? Also, how does it do on the FM satellites? The QST review made it look like it is kind of deaf on FM. 73 John W5TD (ex AF5CC)

W7D Wrap Up
by David Swanson 01 Jul '19

01 Jul '19

Hello VHF Chasers of All Modes, Wyatt and I wanted to send out a few notes to everyone now that the W7D expedition has been in the bag for a few weeks and we've caught our breath. Logs: You can view a complete breakdown of every contact we made, across all bands and modes in the mast log spreadsheet here: http://www.druidnetworks.com/W7D_Master_Logs.xlsx. Obviously it's a Microsoft Excel file, so you'll need that to view it. Feel free to look thru the spreadsheet for your callsign, and if anything doesn't look right please email me direct and we'll get it sorted. LOTW QSLs: On the QSL front, from the master spreadsheet I have generated adif files for each type and style of contact, and those files have been uploaded to LOTW. We have matches across all bands, all modes, using both calls and multiple dates. That said 24 different ADIF files, and 24 different station locations had to be generated to cover all the different grids and calls, so it's possible something got screwed up along the way. If you dont have a match in LOTW, but see your QSO in the master spreadsheet, make absolutely sure you're looking in the LOTW web interface and not the output of a logging program. We have found that a few pieces of logging software (N3FJP in particular) are not handling the LOTW XML output when 2 grids have been uploaded with our station location. If you've double checked in the LOTW web interface and still don't have a match, email me and we'll get it sorted. Paper QSLs: The cards arrived from the printers last Friday, and I spent the weekend getting labels put on everything. Everyone who sent a card and SASE, and everyone who made a donation should (as of this morning) have a card on the way to them. I expect most folks in the US should have it within a week, and folks overseas within 3 weeks. I've still got plenty of cards left, so if you'd like a paper QSL feel free to send your card and a SASE, or email me and we can work something out regarding postage. Folks who worked us on EME from places far off the US Mail beaten path especially, if you'd like a card please email me and I'll arrange to get one to you somehow. Stats: Total across all bands and modes, 950 QSOs were logged on the rove. 730 QSOs were made on 6m Terrestrial, 122 on 2m EME, 63 on 2m Terrestrial, and 52 on AMSAT. On 6m specifically 309 contacts were made using FT8, 226 on SSB, and 195 using MSK144. All EME contacts were made on JT65. On 2m Terrestrial 39 on MSK144, 21 on SSB, and 3 on FT8. 873 Total QSOs were made across all bands and modes while fixed at the camps, and 77 Total QSOs were made while truly operating mobile driving down the road. We worked 477 Unique Callsigns total, 405 uniques on 6m, and 55 uniques on EME. For VUCC/FFMA purposes, we activated 25 total grids, including 6 of the top 10 most wanted FFMA grids. For WAS purposes we activated 5 total states. For the June VHF Contest operating as W7D/R we turned in a score of 46,368 as a High-Power Rover (operating from DN20 and DN10 for contest purposes) and included 320 QSOs on 6, and 2 on 2m. Our total fuel bill (for both the truck and generator) was $1064.40 and we ended up spending $413.25 on Food, Ice, and Water. The final Wrap Up: I'll be writing a proper story about the rove in the coming months - my day job has kept me busy since I've gotten back though, and that takes priority over writing for now. When the story is done I'll be sure to share it with everyone. I've also got piles of pictures, videos, and files full of data I plan to fully use and share because I find it interesting. What's Next: That's the question everyone keeps asking. And honestly, it really depends. Wyatt and I have some ideas floating around, but there's a bunch of logistics and/or paperwork required to pull them off. For now, if you've got some awesome idea for next e-skip season, feel free to get in touch with us and float it.. never know when something will stick to the wall. Last but not least: We have to send out a massive heartfelt thanks to folks who pitched in to help us with the expenses. Whether you donated $5 or $500, every single penny went towards Fuel, Food, Fees, and a few repairs to the rover and some equipment. We said from the very beginning we were doing this rove because we wanted to, even if no one pitched in. The fact that so many of you had faith in us to get out there and put those grids on the air was a huge boost to our morale during some tough hours when we were second guessing ourselves. It also has given us a lot more courage to try and keep pushing the envelope in the world of VHF Roving and rare grid expeditions, when you know the community has got your back. From the bottom of our hearts, we say to you all, thank you. 73! Dave, KG5CCI CC: Wyatt, AC0RA
