Little help?

I'm working on K2 #4913 and I'm getting "INFO 080"
on startup. No relays click, either. I've been working with Scott at Elecraft and we've replaced U1 & Z5 on the rf deck plus U6 on the control board. No luck. All voltages and resistances involving these devices check out except for Z5, which is dead. I'm not hearing anything on 4 mhz, either. I screwed up during install by adding components for the ssb board while building the K2. The manual said if I had those components on hand, to go ahead and install them. So, I did. I should have built the basic K2 first THEN added the ssb board. D'oh! Now I'd like to UN install the SSB board or at least bypass it to try to isolate the error message. Can anyone tell me what to do to do this?

FWIW you might want to check that you have mot accidentally swapped the 4
meg and 5.??? meg xtals on the control board...from memory as I am away from the K2 manual, the error means that the microprocessor on the Control Board cannot talk to the one on the one on the RF Board. I had accidentally swapped the xtals and it took me a while to find the error. Not being able to hear the 4Mhz xtal on a shortwave receiver pointed me to the problem.I swapped them over and the problem was cured.....Hope this helps...Steve ----- Original Message ----- From: "Ken Bessler" <[hidden email]> To: "Elecraft Main Group" <[hidden email]> Sent: Tuesday, May 24, 2005 4:36 PM Subject: [Elecraft] Little help?
