[Elecraft] Loss of VFO B encoder control

[Rick and Theresa Low]

(separate weekend mail sent to K3support)

I'm in the middle of "Test and Calibration", which begins on page 64 of the Assembly manual.

Initial power Checks: satisfactory
Synthesizer Calibration: completed satisfactorily
Filter setup: made it through Filter Bandwidth Setup and Filter Center Frequency Setup...but it appears the settings may not have been accepted...and I've lost control of the ability to change anything using the VFO B encoder.

Symptoms:
tap MENU only brings up the LCD BRT, and I can turn the VFO A and see the display brighten and dim.
hold CONFIG only brings up FW REVS. Again, I can turn VFO A and cycle through uC, d1, FL and dr.

I took apart the front panel and re-checked assembly and fit, with no apparent problems (but obviously I'm missing something). So everything is back together again. I've thought about trying to hook up to a computer to attempt configuration using K3 Untility, but I can't access the rig's menus to set up for RS232 communications.

So, any ideas out there for what I might be able to try this weekend, before the company opens up for business on Monday?

thanks 73, Rick N6CY
