raspberry pi & baycom

raspberry pi & baycom

[folkert]

Hi,

I'm looking for a solution to use a raspberry pi for packet radio. For
example with a baycom modem or so. Now an RPI has only rx/tx so the
regular baycom won't work I guess?
Any suggestions?
I would like to connect things to a 27MC setup.

Hi Folkert,

Have you looked at the TNC-Pi: http://www.tnc-x.com/TNCPi.htm

I haven't tried it myself as I have a heap of Tiny-2s lying around doing 
nothing, but it looks good. I'll try one out one of these days when I 
get around to putting a portable system together.

Cheers,
Mark VK2XGK

Stuart and Mark,

I've ordered one: let's see what it'll do!

Currently I have a pentium4 for doing this but that sucks up 80 watt.

Tom,

Thanks!

At www.ohm2013.org this week someone's going to do a workshop on this.
