[Elecraft] Fw: Err Pl2

[Randy Downs]

Thought I found the problem. I had pulled the top off and found a tmp cable resting on the toroid on the bottom of the 2nd synth board. It ran for several hours with no problem after moving the cable. THEN I put the top back on. It failed when the fp temp got to 37 deg c. If I leave the top off it won't fail. The fp stays at 34deg c. It's thermal whatever it is. I'll email Aptos. Ken have you tried it with the top off? Maybe yours is thermal also.

  Hi Randy,

   

  I would be quite interested in what you found regarding this problem.  I encountered the same problem yesterday after having my KRX3 for about 2 months.  It only would give the error message you mentioned when trying to get the sub to either of those two bands.  Following a suggestion in the owner's manual under the error codes, I did a CONFIG:VCO MD CAL, and it began to work on 10M, still failing on 12M.  At the conclusion of the CAL routine, however, it gives the error code "ERR VCO   E00228".  I have sent info this to Elecraft to see what I should do next and expect to hear back tomorrow.  But I would love to know what you have found as the problem seems the same as mine.  Thanks for any insight.

   

  73,

  Just installed the KRX3 and I am getting PL2 error on the sub on 10 and 12 meters. I did the adc cal on pin 2 on acc jack. It measured 4.91 and I set the config. parameter accordingly. I'll email Aptos and see what they say.  It works fine on other bands. Checked connections etc. to no avail. Any ideas?
