If we are talking about DIGITAL VOICE, I believe the answer is receiving the signal and demodulating it to the DIGITAL baseband stream, verifying the stream integrity, and then, if tit passes the integrity test, reshaping (regenerating the pulses) and remodulating. No decoding or converting to baseband other than to monitor the content, if any.
Integrity check is important to avoid retransmitting garbage. Seems it is a task for a fairly powerful PC with a soundcard, at least a P III with 256 MB RAM and a decent audio card. There should be some sort of periodic beacon transmitted to allow precise tuning to the digital repeater input frequency. 73, Jose, CO2JA ---- W2XJ wrote: > MFJ sells a MFJ-662 pocket repeater for $79.95.
