VFO B dead
Locked
 
|
I just had my K3 in for service and a checkup. I REALLY hope I can avoid sending it in again. The VFO B knob is completely dead. Turning it does not tune VFO B. Also tried the config screen...same thing.I suspect the encoder is bad but it showed no symptoms prior..otherwise I would have had it changed out when I sent it in.All other front panel functions appear to work.Any ideas?73,Gary K9GS

Gary,
If you are not afraid of disassembling your K3, remove the Front Panel assembly and swap the encoder A with encoder B. If the problem follows the encoder, then order a new encoder from Elecraft. If that is not the problem, contact [hidden email] for additional checks. 73, Don W3FPR On 1/26/2020 5:34 PM, Gary K9GS wrote: > I just had my K3 in for service and a checkup.

Hello Don,How difficult is it to replace the encoders? Is there a document that describes the procedure?73,Gary K9GS

Download the K3 Assembly Manual. I believe they just plug in.

...and the first thing to check is that one of them hasn't come unplugged!

Thank you Vic and others.It's been a long time since I assembled my K3. 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

Why not call Tech support? They need to know that your radio was not
working out of the box. Let them help you. That is what they are there for. On 1/27/2020 8:59 AM, Gary K9GS wrote: > Thank you Vic and others.It's been a long time since I assembled my K3.

Gary,
You have to remove the front panel assembly. The encoder must be removed from the rear of the Front Panel. It is not difficult, try it. 73, Don W3FPR On 1/27/2020 10:59 AM, Gary K9GS wrote: > Thank you Vic and others.It's been a long time since I assembled my K3.

Gary,
Before you order a new encoder, remove the front panel and swap the two encoders (they are the same), put the radio back together, and see what you observe when tuning both the A and B VFOs. Dick, K8ZTTT Flying is the second greatest thrill known to man. What is first, you ask? Landing, of course.

Add a tad of De-Oxit(sp) and you may be done! Careful, a little goes a long way.
ps: after applying the cleaner/lib, work the contacts in and out a few times to spread it and wipe the contacts.
