Awhile back I posted about cleaning an antenna tuner I bought some time ago for cheap. Its got a lot of black gunk in it and Ive gotten pretty far in cleaning it but there are two points on the roller inductor which contain ball bearings and I cant really clean in there enough.
I have this ultrasonic mister - its a prop for Halloween. What I am wondering if I should do is just briefly, see if I can use the mister as an ultrasonic cleaner to "get the gunk out" using "citrus solv" which is a citrus degreaser I have which seems to be safe for electronics. (Ive used it with PCBs)
Ive already wasted a huge amount of time on this thing. For a while I had the inductor totally (the entire length) under 0.2 ohms but then I foolishly tried to get more black gunk out of the roller bearings and that seems to have ruined it again, and now the black gunk is semi liquified and wont stay where it was before with the ball bearings, its getting onto the brushes that need to stay clean to make the thing work.
Well, it will be interesting, at least. I am doing this in the kitchen so I have around one and a half hours.
This trying to measure very low ohms without the measurements jumping around has really made me see the value of having a good collection of nice, premium multimeter leads, including ones with super solid, preferably gold banana plugs you can easily solder onto things..
Note to self, buy some.
Yes, an antenna tuner is also valuable for receive, not only that, the cleaner it is the better and you really notice the difference as it gets cleaner.
