[Heathkit] cleaning wafer switches

[L L bahr]

No, I didn't get up on the wrong side of the bed this morning.  I however did get up on the right side of the bed.  I don't know anything about SMT caps nor UHF wireless stuff and how components react up there.  I also don't care what problems Motorola had with some VHF tube rigs of theirs.  I don't own any Motorola HF ham radio gear.  However, I do know and have had a lot of experience with old boat anchor ham transmitters and receivers operating on HF.  I also could care less about being "politically correct" after having to listen to BS shovelled my way day after day.  I have found it to be untrue. I have had just too much practical experience with old ham gear to know some of what I read on here not to be sound advice.

That is not to say, much passed on on this reflector is not good advice.  There are a number of contributors on here who have great practical experience and do give sound advice.  I might also add, I don't know everything but I do know some things very well and do know some things passed on here are just plain not true.

Geez, Lee, get up on the wrong side of the bed today? Don't sweat the small
stuff. As for the above, my company had problems with one of our models of
high-end UHF wireless intercom belt packs from a ceramic SMT cap in the audio
chain causing microphonics in the audio. The fix was to replace it with a
tantalum.
