Hi All,I finally found some time this morning to take apart my K3.Removing the front panel was relatively easy. I swapped the VFO A and VFO B encoders and I did have a defective VFO B encoder .I've ordered a replacement encoder from Elecraft, $60 plus shipping. 73,Gary K9GS

I reviewed the assembly documentation last night. I did not remember that the encoders plug into the PCBA. It looks like a pretty straightforward disassembly and reassembly.Vic asked if the encoder could have come unplugged, possibly in shipping when my K3 was back at Elecraft. I'm not sure how that could happen since the encoder is attached to the front panel with a nut. The nut and the VFO knob would have to both be missing for that to happen. I just wonder if since I have to take the whole front panel off to replace, should I just order replacements?Does anyone know if the encoders can be replaced if I remove the knob and nut without taking the front panel off?If I get some time this week I'll open up the K3 and take a look.73,Gary K9GS-------- Original message --------From: Victor Rosenthal <[hidden email]> Date: 1/26/20 11:56 PM (GMT-06:00) To: [hidden email], Gary K9GS <[hidden email]> Subject: Re: [Elecraft] VFO B dead ...and the first thing to check is that one of them hasn't come unplugged!73,Victor, 4X6GPRehovot, IsraelFormerly K2VCOCWops no. 5http://www.qsl.net/k2vco/On 27/01/2020 6:38, Nr4c wrote: > Download the K3 Assembly Manual.

If the problem follows the encoder, then order a new encoder from Elecraft.

The encoder itself, if you want to re-solder it, is
