FM transponder operating techniques
At this point, once again, a few basic thoughts about operating techniques:
The first and golden rule–first listen, then send!
Here there is a difference of opinion–is it necessary to send the grid square? During an HF contest, such a report would be a valid QSO. In Europe, we’ve developed this style–but isn’t it more effective to work in contest mode? When the satellite was quite busy–callsign and signal report–that was it. Name, QTH or even the station equipment can be exchanged when one is truly alone on the transponder.
Practice discipline, limiting yourself to one QSO each pass–during those precious minutes, everybody has a turn. I often sat there with my microphone in my hand and never had a single QSO.There will always be stations which will be annoying (due to their operating style)–it is, however, senseless to interfere with these stations–it doesn’t help anyone else.
It actually works with suitable discipline and short QSOs–a pass is often multilingual and listening in can be lots of fun.
Perhaps we shouldn’t get caught up with the “daily chaos” and try through our own operating techniques to show a bit more discipline. It’s difficult, but we should try it–even when the finger on the microphone key is itching, the output regulator isn’t doing anything and when one’s eyes are rolling when the name or location is repeated for the third time.

LituanicaSAT-1 FM transponder test
Thanks for all of your reports from today’s successful transponder test! During 14:20 UTC pass over Lithuania FM transponder has switched off automatically after mode transitioning telecommand has been sent to the satellite. This was standard test procedure to verify correct operation of the on board computer during operation of the transponder. Next test is scheduled for Apr 24 from 13:30 UTC to 15:00 UTC. Again we will be grateful to your reports, including FSK packet telemetry on 437.544 MHz. Please respect other radio amateurs and obey transponder operating techniques.

16:15 UTC Oh Lord help us !
12:50 UTC transponder active (but weak due to very low elevation 3 deg)
A courtesy notice that LituanicaSAT-1 FM transponder test is in progress. Today we performed initial operational test over Lithuania successfully. Downlink frequency was noted to have shifted to 435.1755 MHz. More tests are needed to verify that and etermine exact uplink frequency shift but 145.950 MHz should work. Please remember to use CTCSS PL 67 Hz sub-tone. If no problems will be encountered the operational tests for 23rd of April are planned to resume on 12:45 UTC and finish on 16:00 UTC. Just after activation you should here callsign in Morse and short salutation message from Lithuanian president. This identification message is transmitted every 5 min if there is no radio activity as well.
Your reports are more than welcome. Please submit your reports to ly5n@qrz.lt (please provide some supporting data like frequencies, max elevation of the pass, signal to noise ratio, etc.). Also please feel free to share this information through any media channels.
Best Regards,
LituanicaSAT-1 team
