[Drake] TR-4 problem

[Bruce - KB6LWN/rcc]

Gotta luv those message bodies with NO Hard CRs!
Sure makes it difficult to edit a quote :-/

Rob...  Have you tried turning off all the lights
to see if you can detect any arcing going on in
either the relay cube itself of perhaps between
some of the other components you mention ?

73 4 now,
            Bruce - KB6LWN/RCC

Drake R4/T4/T4X/SP4/AC3,  Swan 250 (hoping for a TR-6)

This is roughly one inch square and below a light bulb and some red disks.  When I am receiving on any band the radio will go quiet and the swr meter will peak and there will be an occasional crackle coming from this general area.  I have narrowed this down to be where the noise is coming from but it could something different in the same area causing the problem also.  Has any body else had this problem.  Is this just a case of buying some tuner cleaner and cleaning off dust.  I thank you for reading my email.
