Decode 1k2 BPSK
by Vincenzo Mone 09 Feb '19

09 Feb '19

Hello, I would like to know how to decode the satellites 1k2 AX25 BSPK data with UZ7HO's Soundmodem. I am trying to decode but I cannot get any data. I see the LED lighting that let me understand that I am centred on the signal but nothing comes up the screen. Do I need to make any special settings in the Soundmodem program To get the decodes? Have tried several time to request to the Suondmodem author but did not get any reply. Any help will be really appreciated 73 de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

Geostationary & HEO Satellites
by Les Rayburn 09 Feb '19

09 Feb '19

I’m also a newcomer to the birds, but very excited about it. Likewise, I responded to the survey, but wanted to comment further regarding geostationary and HEO satellites. In the camp of “Both, please.” The HEO birds would once again offer the possibility of DXCC and make WAS more realistic—it also offers more operating challenges. But a geostationary amateur satellite would have many interesting benefits: Provide an easier introduction to satellite operation, and attract new operators. Excellent tool for emergency communications during a natural disaster. Opportunity to experiment with microwave operations. The ability to enjoy satellite operation any time of the day/night. The band is always open. I’m grateful for anyone who incorporates amateur radio into their satellites, but feel that birds should include either linear, digital, or FM transponders whenever possible. Designers are asking a lot of hams when they solicit our monitoring their telemetry signals, and using amateur spectrum for their purposes without much tangible benefit to us. My opinion only. It’s wonderful that they asked us. Dialogue is the key to most human accomplishment. 73, Les Rayburn, N1LF Maylene, AL EM63nf AMSAT #38965, ARRL Life Member, CVHS Life Member, SVHF Member

ISS SSTV Heard 190209-02112Z
by Frank Karnauskas 09 Feb '19

09 Feb '19

>From DM41: For a near overhead pass I got the tail end of a transmission for about 30 seconds. Using a handheld Elk the signal was never full quieting, but enough I think to decode something. At least it was a optically visible pass so it was worth going outside anyway. 73, Frank FRANK W. KARNAUSKAS, N1UW TUCSON, AZ

Downloaded MMSTV to prepare for iss . I do not see pd 120 listed as a mode. Is the the correct software to use? My set up is satpc32 controlling ft817 and ic7100 for No. 2 radio and g5500 rotor. will I be able to run sat32 for tracking and also sstv for the picture? I presume yes. Jim KI6WJ

Fw: Operating SSB sats
by k6vug＠sbcglobal.net 08 Feb '19

Thanks Patrick. Not to spam the BB, but here is one last clip - working K7TAB via CAS-4B this morning. https://drive.google.com/open?id=1DYbg1Ua8_MfZnBjpngBjGxAApB5fcq82 I use the CW beacon to wait for adequate signal and then (at 00:40) switch to the transponder pair, adjusting the uplink with a tone burst until it comes in at about 800 Hz on the bottom display. After that I can move the down-link around the pass-band and don't have to worry about the uplink. HRD (and SatPC32) do a great job of handling the Doppler adjustments. Obviously, you'll notice the signal from the CAS-4B ges pretty strong as soon as it comes up above 15 degrees or so. I keep an eye on the CW beacon (at the left of the waterfall) throughout the pass and watch-out for fading due to foliage, buildings etc. Fast forward to 3:20, I've tuned to K7TAB and start responding. You'll notice that K7TAB drifts a little as he is speaking. However, you'll also notice that K7TAB has moved quite a lot AFTER I have responded and so I have to re-tune the down-link to hear the response properly. Well, that is the issue I wish to illustrate, and am still working on it.... :) Again, sorry for several posts, won't post any more until I have figured it out. Have a great weekend. 73!Umesh, k6vug On Thursday, February 7, 2019, 8:52:05 PM PST, Patrick STODDARD <patrick(a)wd9ewk.net> wrote: Umesh, Very nice! Thanks for sharing the video clip. 73!

Hope the radio is reduced somewhat in price when the initial surge is over.....May still just keep my Yaesu FT-847. Already have my M2 antenna for L Band, but will need a transverter of some type for TX...Any suggestons appreciated..... KJ4EU Jerry

ISS SSTV - Old and New
by Robert Bruninga 08 Feb '19

08 Feb '19

Went out with a bunch of students to observe ISS SSTV downlink. ISS was transmitting but I demonstrated how not to do a pass: OLD FUD Approach: 1) Prepped the laptop. Battery was dead 2) rigged up heavy battery and 60 Hz inverter (1 hr to go) 3) Booted laptop but it was locked out of network 4) After three tires at password, it locked me out of all my accounts on every PC at the school 5) Gave up and dug out a Kenwood VC-H1 SSTV handheld to go with a TH-D72 (30m to AOS) 6) VC-H1 batteries were of course dead 7) Found new batteries (10m to AOS) 8) From 20 years ago, had a hard time remembering how to work it 9) Nothing heard at beginning with 3 element yagi 10) commented how this is not unusual for ISS to change schedules 11) Then heard it, but too weak 12) I explained how to track in AZ and EL and Polarity to maximize the signal 13) Had to keep asking the mids for the TIME so I knew where to point MELINNIAL APPROACH: MEANWHILE I noticed some of the students holding their Phones in their hands at arms length and waving them around. They pointed to ISS... The phones showed exactl;y where the ISS was as the AP placed the ISS and sky track on the sky view. Done! Im sure most of you are well aware of these things, but for the other old fuds: The AP was SKYGUIDE: https://itunes.apple.com/us/app/sky-guide/id576588894 And SKYWALK: https://itunes.apple.com/us/app/star-walk-explore-the-sky/id295430577 I am sure there are others. Time for me to get out of the way... ;-( Bob, WB4APR

Jim, Auto mode will pick it up, but you can find it by right clicking on one of the visible modes. There are far too many supported to fit on the screen. SatPC32 will work very nicely. 73, Alan WA4SCA <-----Original Message----- <From: AMSAT-BB [mailto:amsat-bb-bounces@amsat.org] On Behalf Of James <Brown <Sent: Friday, February 08, 2019 12:25 PM <To: amsat-bb(a)amsat.org <Subject: [amsat-bb] mmstv help < <Downloaded MMSTV to prepare for iss .
