on 80m CW. It took about 15 minutes for the rig to warm up. Any suggestions on how to diagnose the root cause of this problem? This is a K2/100, with the KNB2, KSB2, KDSP2 and KAT100. Bill Coleman, AA4LR, PP-ASELMail: aa...@arrl.net Web: http://boringhamradiopart.blogspot.com Quote

Elecraft discontinue this kit? Or can it still be special ordered? I know there were some complications with firmware revisions in ordering the K60XV. My K2 is mostly up to date - I only need the firmware update for the KPA100, I think. Bill Coleman, AA4LR, PP-ASELMail: aa...@arrl.net Web

iced is that the receiver sensitivity is substantially lower when using the CW filter. Using OP1, it seems to receive normally. I have three filters for CW 1.0, 0.4 and 0.16. When switching to 1.0 from OP1, signal levels drop by about 2-3 bars on the S-meter. Anything in particular I should troubleshoot?
