[Elecraft] K2 Receiver Instability

[Todd Fonstad]

My K2/100  #1130 has developed an odd instability. When first turned on, the 
receiver seems unable to "lock on" frequency, so that CW signals have a 
warble to them. After a few seconds to a minute or more, the receiver 
stabilizes. The instability returns after each band change and often occurs 
when I change the XFIL setting. I don't know if this condition manifests 
itself in the transmitted signal.

I need to take the unit apart to check mechanical/electrical connections 
prior to my using it as my mobile rig in the Wisconsin QSO Party this coming 
Sunday.

Do any of you kind souls have an idea where I should concentrate my 
trouble-shooting efforts? I receive postings in digest mode, so direct 
e-mail as well as posts to the reflector would be most appreciated.

I'll endeavor to inform the group of the outcome.

Best regards,
Todd
