I am using a Zetron Model 48B as a repeater controller. Everything is going fine except my addition of a Arcom RAD audio delay board. The board is working great except now the CWID and status tones are not transmitted.
The RAD is tied to the COS coming from the receiver to act as a gate to eliminate squelch tails...........works great! The RAD is inserted between the tx audio coming out of the panel and the input to the transmitter. My problem is now the CWID and any audible status tones are not transmitted because they are gated by the RAD since the COS is not active. I am now trying to determine where inside the 48B I can gate the transmitted audio ahead of the CWID and status tones generated by the panel. Anyone here know where to find such a location inside a 48B? Randy WB0VHB
