Dear amateur satellite radio operators,

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 determine 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 (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,
