Thanks to you and Don W3FPR. Someone has been in this rig and has these ceramic caps scattered throughout the rig. C153 was 180pf ceramic (now the proper 100pf). C75 was wrong, and now C13 and C14 too.
I'm going to order new 1200pf caps from Elecraft on Monday. I have the original manual and the latest one. Just finished the last of the mods (VFO ALC and KEYCLICK). The 160M low power problem is the last of my efforts to get this equal to a brandy-new 4,000+ serial # K2. If I can get the KPA100 and get it built and tested before the ARRL 160M contest in Dec I'll be a very happy camper. Wonder which gives me greater bragging rights...saying I built a K2 or repairing and upgrading one that someone else built? 8-) Again...I'm very thankful that this group is here for support! 73 de Tom K2TA ----- Original Message ----- From: "Rich Lentz" <[EMAIL PROTECTED]> To: "'Tom Althoff'" <[EMAIL PROTECTED]> Cc: "Elecraft Reflector" <[email protected]> Sent: Friday, November 05, 2004 9:08 PM Subject: RE: [Elecraft] C13, C14 Values RF board K2? > The Correct values are 1200 pf.
