K2 AGC off problem
Locked
 
|
hi all,
I should have posted this before... I found a related message when searching the archive. The reply was: ------------------ Sounds exactly like the problem I had with 5196. The problem was fixed by replacing X1 on the Control Board. You will probably find that CtrlBd-U2-1 goes to about 6 volts when you turn the AGC OFF virtually shitting down the IF amplifier. I encourage you to communicate with Gary ([hidden email]) regarding this problem. Yesterday, someone reported a similar problem with a close serial number(s/n5219). ---------------------- My serial # is 5203, so maybe I am also affected by this failure? 73! de Werner OE9FWV -- EYEDROPPER: A clumsy ophthalmologist Email powered by Pegasus Mail free at <http://www.pmail.com> Homepage: <http://www.qsl.net/oe9fwv/> Fone +43 5522 75013 Fax +43 820 555 85 2621 Mobile +43 664 6340014 Elecraft K2 #5203 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Damn, mine too. #5209. Hold PRE/ATT and AGC, it says "OFF", all bars light and the K2 goes deaf. Hold them again, it says "On", the bars come down, and stuff can be heard again. I've not had a chance to measure Ctrl-U2-1. Doing WHAT to the IF amp?

hi Nick,

Nice typo! :-) well, I should have read the quote before pasting it - anyway, we are probably having the same problem and it shouldn't be a great deal to exchange a Quartz. I wrote a message to support and am awaiting their advice. 73! de Werner OE9FWV -- Das Problem mit den alten Leuten wird nicht weniger obwohl so viele sterben. Aber es wachsen immer neue nach.

I corrected the "typo" in an email to the reflector shortly after re-reading
what I had sent. "u" is right next to "I" on my keyboard <g> 73, Ken K3IU -----Original Message----- From: elecraft-bounces+kenk3iu=[hidden email] [mailto:elecraft-bounces+kenk3iu=[hidden email]] On Behalf Of Nick Waterman Sent: Thursday, March 23, 2006 4:20 AM To: [hidden email]; Elecraft support Cc: [hidden email] Subject: Re: [Elecraft] K2 AGC off problem Dr. Werner Furlan wrote: > I should have posted this before... > I found a related message when searching the archive.
