[Drakelist] Deoxit debroke it.
Just tried some Deoxit for the first time after hearing so much about it here on the list.. afterwards, however, I wondered if I might have missed some pithy warning not to use it on Drake rotary switches? My T-4XB R-4B had been working OK before I cleaned a couple of the rotary switches on the transmitter with a tiny bit of Deoxit per directions but when I fired it up again, the receiver won't mute... strange because the only thing done to the setup was the Deoxit on the T-4XB and I'm certain I didn't poke around hard enough to lift or dislodge any prongs on the switch so I'm baffled on this one. None was used on the relay and it closes OK on tune the mute cable checks out and so I'm wondering if the Deoxit might have damaged a contact on the switches? Has anyone else had problems after Deoxit? Comments would be appreciated. Thanks, Doc ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Doc - Nah, I don't think you can blame it on DeoxIT.

Hard to imagine DeOxit causing the problem as you used it sparingly (vs flooding the wafer and possible inducing swelling). Did you exercise the rig immediately after applying the DeOxit? It is somewhat conductive until dry.

[Drakelist] Deoxit debroke it.
I sold a Drake C Line to a ham friend a few years back. It had been fully functional for me for months and the fellow came over to pick them up. I fired them both up in front of him, on my antenna and went everywhere, all bands, everything worked - HAD FUN! He carried them out to his truck (smiling), they went on the passenger seats with towels over them. I get a phone call an hour after he left (here), him wondering why this receiver is DED. Nothing - flat out unresponsive. My jaw hit the floor. Something happened in the cool down period at my place, during the truck ride, or upon setup on his side. He's an honest and smart ham. I learned never to assume any cause nor affect with things so mechanical in nature. My guess - the deoxit may seem like a red flag but it could be s many other things... Steve Berg wa9jml at tbc.net Tue Mar 2 22:18:41 EST 2010 I have used de-oxit many times on old National, and Clegg equipment, both on switches and on pots. So far, I have had no trouble from it. I may even have saturated the wafers on a switch or two in the process to no ill effects. I am much more careful with it now, though. Many of these components are almost if not impossible to find now, and I don't want to take any unnecessary chances in wrecking something.
