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?
thank you for the reply, I really appreciate it. It's a kind of stealth attempt to get DATV on the air without making either XYL nor the neighbours suspicious. I really would enjoy a larger dish but the 88cm is completely fine with everybody ('What programmes are you watching?') despite the POTY having replaced the LNB.
Will actually refit my Portsdown to 2020 after checking the BATC wiki.. big thank you to everybody involved.
