Good idea. As I understand it 'Clicks' = clicks heard every 5 kHz or thereabouts even if the antenna is discoinnected, generated inside the K2. 'Clunks' = strange behaviour noticed or sounds heard while tuning when *very* strong signals are being received in or close to the band in use. 'Clunks

First of all let's be sure we are all on the same page. Please define "Clunks" vs. "Clicks". While it would be best to find a total cure for the problem, anything that reduces the severity or frequency of them would be most welcome. Darrell VA7TO On March 25, 2007 03:16 am, Geoffrey Mackenzie

This might be a tough nut to crack in terms of the surgery required. From a quick thus limited investigation into this "clunk" problem in my K2 I am reasonably certain that the lack of shielding to protect the VCO and Reference, together with the lack of suitable interface filtering , is respo

I agree that the synthesizer "tuning clunks" every 5 kHz in the presence of strong signals needs to be addressed. I know that Elecraft found that muting the receiver to eliminate these noises was worse than the noises, but there must be a solution to at least lessen these "tuning clunks." On M
