Have you calibrated it with a known source? Elecraft makes a nice signal generator kit that works great for this. You do need to enter the gain on the 5 pole filters. They are negative numbers so that might change things.
Do you happen to have the pre amp on. It is generally not needed on 20-160.

It acts as if I had maxed out the value for the crystal filter gain in the firmware, or had the PreAmp on. I have made sure the gain is at zero and moved the crystal filters (12.5 and 2.7) into different spots, but still too hot. I can make it more normal with respect to AF gain and S-meter if I turn the ATTenuator on. I have the 2.7 filter installed and have not added any gain in the FL1 filter definition. I did a master reset and also loaded old versions of the firmware but no improvement was noted. I have emailed my request to [email protected], but want to post this to the list - anyone seen their K3 with these symptoms? Thanks, Don Rasmussen Carlsbad, Ca. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
