Has anyone hooked up an amplified speaker to the output of one of these
Argent Data Systems RFM12BP 500mW Data Transceiver - 433 MHz and talked to
it in FM voice?
The idea of a postage stamp 70cm voice transceiver can have some ham radio
uses I think.
It is FM so why wouldn't it work for sound unless the data inputs and
outputs are hard limited and driven into a data-limitesr before the input
It has a lot of pins. I wonder if any of them give access to the analog
These are common RFM chips, but Argent Data's is a high power one (0.5W).
