Barry, Without doing any measurements it may be difficult to say precisely, and I would think there would be a bit of difference from one K3 to another.
However, there is a quick and easy way to accomplish that - note that the S-meter increases as the RF gain is reduced. So if you want to increase the AGC Threshold by (say) 3 S-units, disconnect the antenna, and reduce the RF Gain until you move the no-signal S-meter up by 3 S-units. That should be close to your goal. 73, Don W3FPR On 12/9/2010 9:07 AM, Barry N1EU wrote: > > Cady, Fred wrote: >> I made some measurements and have posted the results for your perusal >> and information at www.ke7x.com. > Very interested findings - Fred has a graph of AGC action with AGC THR=8 > labeled figure 3 on http://www.ke7x.com/home/the-k3-agc-story : > > So I ask this group: is it possible to raise the AGC Threshold from s3 to s6 > or s9 by simply reducing the RF Gain control?
