Re: GM300 mike gain

Is it going to need to send PL? If not, then you could crank the DEV settings in RSS or the pot up to where it gets to where you need it. The PL DEV would be way wrong unless you did a pretty much full alignment. Then again, if you are sending data, you probably want around 3.2 khz dev. Might not be...

Re: GM300 mike gain

There is no mic gain on a GM or Maxtrac. The R302 POT is the VCO modulation and it affects both mic and PL deviation. The only real way to up the mic "sensitivity" is by going thru the alignment and setting things higher. That said, you *MIGHT* be able to turn up the dev with the VCO mod pot and *MA...

Also you have to jumper the two pins that are closest to the outside of the radio.
Jumper the top on to the bottom one.
A typical Berg jumper from computer boards will work in a pinch if you don't have the accessory plug that goes to that 16 pin socket.
