QRP on WB transponder?
Posted: Mon May 11, 2020 10:51 am
A question to the experts:
What is the practical (demonstrated) limit in terms of QRP operation on DVB-S2? More specifically, I have a (XYL-limited) 88cm dish and a working Portsdown, which is in the process of being upgraded to V2019 (limeSDR mini). I know that DVB-S2, QPSK with FEC 1/2 should have little CNR requirements and combine this with 66kS rate would require even less power (5W according to https://wiki.batc.org.uk/Transmitting_O ... TV_signals ?).
I am aware that 66kS with FEC 1/2 will be likely a horrible picture but is is enough for a testcard?
