Protocol

[Jay]

Hi John,

When you release the protocol, please keep me in mind

I write a few programs for the ICom PCR radios and have the IC-R2500 with a D-Star module installed wich allows reception only. Adding support for your SSTV protocol would make my users really happy

Regards,
Jay

Hi Jay,

I suspect you're after the protocol for broadcast mode. I can post that later. The protocol for targeted mode requires a two way "conversation" between radios so possibly isn't that much use to you, although, I'll also describe that. Its not overly complicated, you really only need to monitor the DV data for headers and end of file commands from the transmitting station.

The images are transmitted as 240x240 jpeg files using base64 encoding.
