Hi Folks, I have an Elecraft K2/100 (S/N 01136) given to me by father (SK) some years ago. I am finally finding some time again for ham radio and would like to get this rig up and working well. It has the A to B mods applied, and includes the options for SSB, DSP, 160/Rx ant, etc. I have applied the BFO and PLL upgrades.
My current problem is that the RF gain knob doesn’t seem to do anything. I was expecting to hear some difference in the level of received signals and to see the S-meter go to the right as I turn the knob fully CCW. Turning this knob seems to have no affect on anything. Any help would be appreciated! I mention the following details in case they are relevant: my father was mostly interested in 160m cw, so I’m not sure if other aspects of the radio received attention when he built it. The AF gain knob is scratchy - I’ve read about the mod that addresses this, but haven’t yet applied it. The AGC needs adjustment - I can tell the difference in volume AGC On vs off with no antenna connected. I don’t know that any of these are related to the RF gain. Before I open things up to measure and replace the RF gain pot, are there other things I should check? A quick check of the email reflector archive didn’t turn up anything obvious to me. 73, Mike AE6NH ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
