Pasted below is an exchange between myself and Elecraft on a similar problem that I had. I exercised the four pushbuttons to the left of the main vfo knobs a few dozen times each, and it started working again. I ordered four encoders at $2 each, but the problem has not recurred, so I'm not going to mess with replacing the encoders.
Dave Hachadorian, K6LL Yuma, Arizona Hi Dave, The most common reason for that to happen, is that one of the 4 encoders to the left of the main VFO knob is developing a problem with the push in switch that is inside the encoder. Often wiggling the encoders or pushing their knobs in several times will clear the fault. If it becomes persistent, the encoders will need to be replaced with new ones. And yes, sometimes it is just a front panel poor connection. You can do exactly what you said about pulling off the front panel and pushing it back in. If you have some DeOxit (Radio Shack sells it), apply a small amount on the front panel connector pins to help stave off moisture related corrosion and poor contact. -- 73, Gary AB7MY ========= [email protected] Elecraft Technical Support On 9/26/2011 8:15 PM, Dave Hachadorian wrote: Hi, Last week, almost all of the front panel buttons on my K3 s/n 993 stopped working. I turned the rig off, and back on again. The POWER switch worked, but none of the other buttons worked. I tried to do a switch test, but the menu/config button didn't work, so I couldn't get into config. I tried to do an EE INIT, but the shift/lo button wasn't working either, so the EE INIT failed. I kept floundering around, pushing buttons, and then everything started working again. In the CQWW RTTY contest this weekend, the problem showed up again on Sunday morning, after working fine on Friday evening and all day Saturday. I gave the rig a good smack, and it started working for a couple of hours. Then it failed again, and couldn't be fixed by further smacking. Is there an issue with oxidation of front panel pins, where they engage the main board? Maybe I should partially disengage the front panel by 1/4 inch, and put it on again to clean the pins? Please let me know, because I absolutely need this radio for Sweepstakes CW in November. Thanks.
