Hi Mati! For my part, I have tried several solutions, but in the end it all
boils down to two possibilities: - use Barry KV4FV's gr-morse-code-gen (there
are several examples on the net) - sending the sidetone of a “physical” keyer
as TX modulation (as is done for FT8 digital modulations, etc.). At this point,
it will no longer be A1A but A2A; in practice, nothing really changes. Other
solutions suffer from various defects (latency, loss of characters, etc.). My
TRX SDR [https://sourceforge.net/projects/urtx/], not yet updated to the latest
version (lazy me...), may be of help to you. I use it for traffic on QO100,
mainly in CW considering my “magical” 500mW. I would like to take this
opportunity to wish you and the mailing list a happy holiday season. de I3VFJ,
