[Elecraft] K3 Error PL1

[Richard Thorne]

Hello Group:

I turned on my K3 this morning and noticed a receiver problem.  As I 
tuned the main vfo the receiver sounded choppy.  I turned the K3 off and 
back on and the display read "ERR PL1".  After reading the manual I 
performed the VCO calibration. 

After the VCO calibration was complete I had two additional err messages:

- E 00005/ERR VCO
- E 00255/ERR VC4

Any ideas?  I do have the sub receiver installed. I installed it a few 
months ago and every thing was working just fine until this morning.
