Batboard

Hello, I'm trying to use the stock PL board (reed type) in a Mitrek in repeater configuration for both encoding and decoding. I know that the board & reeds are good 'cause the were working in a different radio (non-duplex). I have done all of the mods which keep the decoder on during transmit but I can't seem to get the thing to decode a tone. I'm also grounding pin 16 on the main connector to activate PL. Anyone have any experience with these? Thank you.....

The Mitrek PL board altho it has two reeds can not do duplex.
The two reeds are for different encode and decode codes. They share the same circuits in the IC.

You are going to need to add either a receive decoder or tx encoder in addition to the PL board.

I remember having a Mitrek PL board with one reed send a PL tone but only while it was decoding the same PL code. We do not have any PL tone on the tail, makes the user monitor the channel or they do not get the tail.

...You can' t use the reed type board for simultaneous encoding- decoding- however, the reedless type does a most excellent job of doing it- I use them all the time w/ mitrek repeaters...not only that, but you can use that IC that they use in their "gyrator" circuit ( the 8 pin dual op-amp near the front of the board where the interconnect is) that's original purpose in life was to suck out the rx pl tone - with a little creative re-wiring and the addition of a darlington xsistor you can have your cor, tail and audio gating on the board that is the closest thing to "factory" ...at first glance, it looks perfectly stock...only downside is that both rx and tx tone must be the same...
