soundmodem TX on HF again

[John Goerzen <jgoerzen@complete.org>]

Hi folks,

Well I've got soundmodem 300 baud working, sortof, with 900Hz and 1100Hz.

I'm using it on HF.  I seem to copy other stations just fine, but they 
have difficulty copying me.  They can, sometimes, but it is hard going 
and lots of retrans on my end.

On the output side, I've tried running loud volume and quieter volume. 
K7TMG suggested that I set the power on the rig to 100W, then reduce the 
audio volume to it until it is transmitting with only 50W.  That maybe 
helped marginally.

Any other suggestions on what I could do to improve the TX side of 
soundmodem on HF?

Thanks,

-- John
