Re: Click on keying ptt

 

Hi Allard,

please find a suggested trial circuit to move pin 7 on LM386 to '12V. This circuit will be controlled directly from the PTT.

No problem should result on the LM386. Taking pin 7 to +Vcc 12V will increase the voltage across pins 8 and 1 reducing the LM386 gain.

I hope the fix will work, contrary enjoy the soldering ... hi
