I tried something similar (TX-FM AUDIO from Abacom
http://www.abacom-tech.com/) for an APRS transmitter with a D7 on the
receive end. I chose this transmitter because it had audio inputs and
a matching amplifier to get the power up to (IIRC) about 0.5W.
The SAW stabilized oscillator wasn't very stable. The frequency
drifted all over the place, and I didn't get too much data from it. No
good for APRS.
If you use them in a TX/RX pair as intended, I have no idea how they'll
actually work. I'd be interested to find out.
