I didn't write it directly, but I assumed from the description you would
read that I indeed run full duplex (and to add to this: my system is
Linux, not Windows). If not Direwolf will wait for a free window to
throw out packets which will never happen because FS-3 is on all the
time. No, everything is working, except for the problem I described
before: all commands to the bird are heard and responded to, but
uploading a message will fail.
Desensing is also not the problem: got the appropriate filters in place
for that. Cheers,
Hans
