I had a similar issue with mine last weekend, but the error code on the sub vco was 00374
I swapped the sub and main vco resulting in the error repeating on the main vco It appeared to be a board issue. So I called Aptos monday who advised me to open up the toroid on the vco board and spread the turns slightly. Been on a road trip since so havent had chance to try yet Dave ww2r Message: 8 Date: Tue, 9 Dec 2008 12:50:43 -0500 From: George Sereikas <[EMAIL PROTECTED]> Subject: [Elecraft] KRX3 Installation ; ERR VCO 00227 To: [email protected] Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes After installing the latest firmware, I installed the KRX3 that I just received yesterday. All went smoothly until I went to Calibrate KsYN3 (p 43 in KRX3 Manual). I keep getting ERR 00227 VCO. I also received the ERR 00228 VCO one time. Any ideas where I might look to solve this issue?
