Hi Andy,
In the U.S. ( correct me if I am wrong) which you are located, 300bps
for MIL-STD-188-110 is not legal for data on HF, nothing is due to
the symbol rate.
Anyhow, what ever, who ever, where ever does using MIL-STD-188-110
within the ARS, the standard 1800hz PSK carrier and 2400bps symbol
rate necessitates a 3Khz BW, so if you are not at least at 2.7Khz IF
BW, the results using the standard modem settings will be poor and
the higher the data rate the worst the results under perfect channel
conditions, add in QSB and the like and you get the picture.

Rick et Luc,
I have set mine to no more than 300 baud to make sure I am legal
below 10M, let me know if you want to sked.
Of course, with ALE...we should not need to "sked"...., just call me :>)

Luc , VE2???, is also playing around with this. Bonnie talked me
through the up and I was able to make a link with Luc under fairly
poor conditions. I will be happy to do some tests at 300 baud or less.
Has anyone tried it at higher rates on 6M ?

Hi Andy,
What software do you suggest? If PC-ALE will be able to key the PTT line
via CAT interfacing with an upcoming new version, this should work for
me with my main digital rig which is the ICOM 756 Pro 2.
But if I understand it correctly, I could use my Ten Tec Argonaut V,
although I don't normally have the fans plugged in since I mostly use
this rig for QRP CW and for general monitoring.
Since you can select the baud rates, if you work below 10 meters here in
the U.S., you can just set the maximum rate at 300 bps and both the
minimum and default values at 75 bps.
For stations who are close together, say 30 miles, with modest antennas,
or much farther with gain antennas, this should also work up to 1200
baud on 10 meters and higher on 6 meters and up. This won't give you an
accurate lower band HF experience, but might give you some feel for how
well (or not) the modes perform.
Isn't anyone else trying out these software programs with
MIL-STD-188-110 and can give us some feedback on their results? Is it
due to lack of interest, or getting it to work with your equipment?
