[aprssig] 6 meter APRS

[Chris Moulding]

Yes, that's how it should work.

It's early stages for the program but I'd like to run the PSK/QPSK audio 
at 700 Hz so that with an
audio feed from an existing HF receiver driving a 300 bd TNC running at 
1600 / 1800 Hz the
PSK would be 1 kHz below the existing APRS.

On 30m that would be 10.1483 MHz. Seems OK in Europe, would that 
frequency be OK in the US?

The receive side uses +/- 50 Hz AFC so the tuning would be easier than 
existing packet. It's using
the PSKCore DLL by AE4JY. A simple test program works well. It just 
needs the interface to UI-View
completing for the first on-air tests. I'd better get on with it!

73s,

Chris, G4HYG
