[aprssig] Radio Telemetry

The XR2211 and XR2206 have been used for years in TNCs.  I used them myself
in the development and testing of the OpenTracker.  I seem to remember that
the biggest pain with the XR2206 was the fact that it needed a bipolar power
supply.

I've been thinking of tweaking the OpenTracker code to send ASCII - it could
do baudot, but it'd be very limiting, and a lot more work to implement.
It'd be more an academic excercise than anything, but who knows... maybe
someone wants an HF ASCII weather station or something.

Thanks Steve

Hey I know Baudot and RTTY use "short codes"

I was hoping to use straight 8 bit 1 stop bit dual tones

Do you know if a windows program that will decode "ASCII" ?

It is so easy to buy gear of the shelf. I would like to have a go
myself. I am competant with PIC chips etc.

Cheers
