Haven't experienced any problems with the four 9612's on our LAN.
Copy is generally 99% +, with good SNR, using a repeater.
There is also one AEA and one TAPR (at the repeater) modems
on the LAN, and I have used a PACCOMM at times. I"m not sure
there are any secrets, as the modems are a mix and were set up
by different individuals. I set the TAPR modem (which every one
is receiving) around 5KHz deviation using a service monitor, but I'm
not sure it is giving me an accurate reading. The spectrum looks
good and is not exceeding the channel width (which is why I'm not
sure it is an accurate reading on the deviation). It's been awhile, and
I don't remember all the details.
