M03 Alert Monitor
Posted: Mon Nov 05, 2012 8:56 am
Does anyone happen to have a schematic for an M03 alert monitor (VHF High)?
I just picked one up on Ebay for $15 on our FD's frequency, and am going to add tone decoding to it (this radio doesn't have it built in)
I have the PL decoder, DTMF decoder, and reset circuit, but would love to know where to interface everything without having to try to reverse-engineer a 70's era circuit board with bad sight...
Thanks
