I have an RCI 2950 Non DX Old school Radio. Just wondering is there a way to lower the talkback. Thanks......................John.

If you have the diode clipped to give you a talkback, you can lower the talkback by adding a .047 uf cap from pin 4 of the audio chip to ground. Pin 4 should be the input to the audio chip.

thanks Tim will look into this. Im not savy like the olden days with electronics. But will try and locate it................................John......

You don't need to worry about the diode. I just assumed that it was how they put in the talkback. The diode is near the audio chip and in front of T1, its D-78, if you wish to locate it.

Hi Tim,
I actuall clipped on leg of the diode and it was just to loud. Guess cause I run my set up that way. But i re soldered it back. I didnt know for sure how to decrease some of the talkback. But Im going to give it a try again. Thanks Tim.

Simply turn down the mike gain some and the radio will still modulate enough to get out.
