Since there has been a lot of conflicting reports on how well
the Motorola Radius mobiles will do 9600 baud packet, I figured
I'd try one.
The unit I used was a Radius M10 Model M34XVC20F3AA. This is a
25w UHF unit with 2 layer logic board w/ 16pin accessory connector
on the rear, 25 KHz spacing ("D" filters), and single channel.
TNC used was an AEA PK-96.
I used the mod mentioned here:

The good news?
The modification isn't hard at all. A good afternoon project.
Great deal of that was spent checking deviation, adjusting it
back on frequency, and routing the TX injection point wire out
the back.
9.6k RX performance looks good. I have no way of testing BER
rate and my scope is down so I couldn't look at the eye pattern.
Judging by simply monitoring the local 9.6k channel, it seems to
do a great job on receive. I don't think it ever failed to decode
a packet off the air.
The bad news?
9.6k TX seems to be a total flop. I didn't have any trouble
getting deviation up to 3 KHz, but nothing seems to decode it ;-)
I think the D72 decoded one packet from it and that was out of
several hundreds of tries. With the scope down, I don't really
have a way to test further.
Conclusion?
Seems like a great 9.6k receiver, but useless on TX.
No great loss, they make a very nice 1200 baud radio.
