My station's performance on 1200 packet seems to be appalling; some
packets simply don't seem to get decoded properly. The biggest problem
is that my transmitted packets don't get decoded properly on the other end.
I've tried increasing the txdelay and it doesn't seem to make
a significant difference. The station I've been testing with is
just a standalone TNC digipeater. I think the power output here should
be good enough over this path (25W into a vertical).
Receive decoding is fairly reliable although not 100%.
I'm using the soundmodem with an SBPro card. The eye diagram in
smdiag looks OK (although as the manual page notes, the diagram
is distorted for 1200 mode). Can anyone with a reliable setup post
a screen grab of the eye diagram? I'd like to see how mine compares.
I mainly use APRS here, so poor performance is not going to fill
the channel with retries. It'd still be nice if it worked a bit better
though. Any ideas where I might be going wrong? The rig is a Yaesu
handheld. I'll try an ex-commercial set once I make up the cables.
thanks
