Re: PTT pop hack

 

OK Simon,

What I had not mentioned is that the carrier balance pot needs to be re adjusted. Listen to the carrier leak in a near by Rx and adjust for a
minimum or scope the output after removing the mic connector and adjust the 106 for minimum carrier.

Make sure the series cap you put is not more than 0.1uF.

I cut the track beteween the wiper of r106 and r38 and confirmed the break with my multimeter. Then put the cap across that break.

The reference in my earlier post to "path to ground" was refering to the path through the diode and then on through r39, ie the path we are putting the cap in series with.

Regards
