Oops! SORRY! One omission! I did find on Amazon a "LoveRPi 4GB
with heatsinks" for $119.99.
My mistake!

I suppose a lot of custom code would be required to
handle this, but there should be some suitable packages for the
Raspberry Pi that can be incorporated.
Hmmm.. ok, I can give you some ideas of some LInux projects that
have components of this functionality:
I'd like to put a couple cameras up there monitoring a
couple different things.
Any data over a repeater's audio path is going to be slow so you're
going to have to de-res the pictures pretty heavily.? For example, a
320Kbyte picture will take about 1.3min via a digital SSTV mode.?
?? - GraphicsMagick to do scripted image modifications
What I'd like to do is the ability to send a DTMF code
to get a snapshot from a camera
?? - SvxLink has some nice scripting abilities which you can
probably use to trigger various functions from DTMF.
then transmit that via SSTV over the repeater
Qsstv has some very powerful analog and digital SSTV modes though I
don't know strong it's automation support might be.? What kind of
repeater controller is running at your site?? It will clearly need
another "port" to connect to the computer sending the function.? If
it's a digital repeater, some versions have bulk file modes that can
possibly make things faster than using SSTV.? Good luck!

This project will strictly utilize existing analog FM channels at the site. However, the question is not really the transmission medium, but the nuts and bolts of taking the picture and transmitting it on command.
Thanks for your input.

I use DH1TW's Remote Audio?
for exactly this.
For rig control if required I use ser2net and com0com
See attached drawing. For just audio and ptt you only need the RemoteAudio part.?

Hmmm... I've never heard this this "USDX" project so
I did a little Googling:
?? - Background and a little history:
?? - Main page:
It sounds like it uses some novel tricks to create a 5w SDR from
an Arduino and amplifier tricks but I would be worried about both
it's RX and TX performance.?
Anyway, as remote control, you're already asking this on an
existing email thread with some provides ideas.? Have you tried
any of those options?? You would ultimately just need to connected
a USB or I2S soundcard from the Rpi into the USDX's microphone in,
audio out, and connecting the Rpi's UART to the USDX's CAT port.?
At that point, it should be possible to remote control.? There are
lots of other discussions in the archives around this topic using
say NX, TeamViewer, Mumble, Skype, etc.
