[Hallicrafters] SX-101 issue

[Al Parker]

Hi Bob,
	I've been watching the thread, and having had several of the SX-101 
family, was thinking along the same lines as Mark and Jeff, - the 
bandswitch.  My present, an SX-101A, has been in an "occasional" 
operating position since I bought it abt 8-10 yrs ago.  I've done very 
little to it in that time, but it's almost always had a similar problem 
as yours and exercising the bandswitch is the usual fix.  I think I did 
get in there once and used DeOxit, which has helped.
	I got my first one about 17 yrs ago, and I did check the "pink chiefs" 
at the selectivity switch, and found they were OK, so haven't changed 
them on any since then.  Maybe they're getting to be a problem by now. 
One of these days, when I get a round tuit, I'll get into the 101A and 
five it a good refurb job.  There was a great series of articles in ER, 
by Ray O., on the complete job he did on his 101.  I recommend it for 
anyone trying to do more than a "get it going" job.
	I suspect you'll solve your problem with a careful application of DeOxit.
73,

Al, W8UT
