Thanks to everyone for the suggestions and help... As Don pointed out the IF gain decreases with an increase in voltage. I set the voltage at a point where there is no difference in the background noise with AGC on and off and the sensitivity is better....I built the little Elecraft generator a few minutes ago that I had been putting off for months.... :) The new K2 shows SO-9 in the 50 micro position and the old one does too... AGC threshold voltage is only 3.30v now though, but everything seems to be working fine... I guess that won't be a problem.. thanks again Tim Nz8J ----- Original Message ----- From: "NZ8J" <[EMAIL PROTECTED]> To: <elecraft@mailman.qth.net> Sent: Monday, July 25, 2005 12:57 PM Subject: [Elecraft] AGC Threshold voltage?
