from the days of packet radio, it should be that nothing will
get off the ground in any meaningful way if users have to build
something, or modify radios to make them work at higher speeds.
1k2 survived so well because existing external connectors could
be used to get audio to/from the radio. 9k6 would probably stand
a reasonable chance of getting up today because 9k6 ready radios
are available. To go beyond 9k6 would require <insert
speed> ready radios off the shelf.</font></div>

What kind of external processor could we plug into the back of a 9600

<pre>Not very practical. The internal TNC would have to operate in KISS mode to allow an external processor get at the raw packets. Given the notorious unreliability of the KISS mode in many APRS radios, this is dubious at best.

<pre>What could we do with it? All I remember about NETROMS were something like this:
1) You could connect to any node and see what it could connect to.

<pre>Except for a few DX packet clusters, There is virtually no packet
infrastructure left. Conventional connected packet (and BBS systems) were
killed off by Internet email in the 1990s, cellular text messaging in the
2000s, and full internet access on cell phones in the late 2000s/early 2010s.
Remember, it was all those abandoned TNCs, left over when the connected packet
era of the '80s died, that were the foundation of APRS........

<pre>These cheap cameras are USB-based and require massive software stacks provided
by real operating systems like Windows, Linux, iOS or Android. Not something
you are going to run on a PIC-class controller.

<pre>Even a small JPG image file is HUGE (i.e. 10s or 100s of K) compared to the
bare ASCII text files of the packet messaging heydays that were at most a few
hundred bytes.
I once tried transferring a 320x240 SSTV-like image over packet. With all the
back and forth transmit-ack-transmit-ack hand-shaking on each few hundred
bytes, it took over 15 minutes to send one image. And that was direct
radio-to-radio without the overhead of digipeaters, nodes, etc.

<pre>but we are not using our 9600 baud

I'm thinking it does need to be seamless with the existing NETROM, THENET, KA
node archetecture for the long haul links so we can use a lot of our existing
stuff.
