Radio Shack sells a 120VAC DPDT relay that will work as an antenna change over and receiver mute relay. I have used this same relay with my Apache and Mohawk. ...
Hi, You'd probably do best to buy a used Dow Key coax relay type DK60-G2C The Dow Key instruction sheet is here: http://bama.edebris.com/manuals/dowkey/dk60g ...
I'm sure this isn't the first time for this topic---rotary switches that won't rotate. These are used in almost everything we cherish and rebuild. The problem...

You might try a product call "PB BLASTER" spray ..it will free up and remove most any deposits...be careful with it because it is a strong solvent and will...
I had a switch that wouldn't budge, even after squirting WD-40 into it. I finally decided that I would turn the shaft or break it. It was still mounted in the...
Good Morning Paul. I've used a soldering iron on many occasions with success. Just heat the end of the shaft and then try moving it until it is loose. Apply...
Almost any of the various penetrating fluids will likely work - Kroil, PB Blaster, Liquid Wrench, WD-40, etc. I also suspect that naptha (Ronsonol lighter...
Lowes used to sell a teflon-moly spray that is excellent. It remains as a "dry" lubricant that does not attract and hold grit like most other lubricants. ... ...
Thanks all who provided insight into correcting this problem of stuck switch. The problem was getting the solvent to flow between the shaft and the bushing to...
Great Videos. Wonder what the labor costs would be today if they still used all the manual operations. Notice all the women were well dressed and hair fixed....

Anyone know why more valves weren't implemented in metal? Was it the difficulty of matching glasses to metals or some other reason? It seems to me that a...
I have a question I would like to put out for discussion. After using my SB 200 I notice that my Genie garage door opener will not work. The opener has a...
Frank At the opener: Put a 0.01mfd disc ceramic cap across the leads to opener pushbutton. That will likely fix the problem. Paul K0UYA ... From: "Frank...
... The SB200 may be putting RF onto the power lines. Try putting an EMI filter on the door opener and/or the SB200, or at least a ferrite. Kerry AB1HA...
I have a similar situation like Franks. When I run my SB-230 (in my upstairs ham shack), it makes our phones downstairs ring...just once...but not the one...
You might try relocating your antenna. An antenna produces high RF fields and if the antenna is located in close proximity to sensitive electronic devices such...

Try a few drops of MEK administered from the shaft end. Repeat a few times, tapping lightly on the shaft. Once it moves, use penetrating oil. Be aware that MEK...

Thanks to Jim and Ed. In retrospect, it must be cost and reliability. Metal-glass seals are probably much easier and reliable if small. And if a glass...
