Hi Jeroen,
I do actually want the decoded audio and the text string.
So, should I decode to voice, the 700C file saved, after the QSO
has finished?
As I've mentioned, I'm not a "C" guru but I see a repeater as a very worthwhile
project offering a remote area digital voice communication method for us hams
where, unlike the commercial users eg. ambulances who have many bases so
HF skip will always (~mostly) get the signal to/from base HQ.
Also, after a call to freedv_rawdatarx() is the text string recovered?
It's used to "trigger" retransmission.
