<div class="moz-cite-prefix">The VRM650 is an RD-LAP machine,
configured ex-factory for either 9.6 or 19.2 kbps (12.5 or 25 kHz
channelisation respectively).<br>
I don't know enough about RD-LAP, but presumably, you will be able
to encapsulate AX.25 packets inside of RD-LAP packets?<br>
<br>
If the amateur community gets enough of these radios to make it
worth while, it is probably within the realms of feasibility (with
considerable effort) to reverse engineer the VRM650 and write a
"ham" firmware for it "from scratch" which speaks AX.25 (and
doesn't have copyright issues with Motorola service software)<br>
