Re: [amsat-bb] Opps! D/C water ingress

["Robert Oler" <cvn65vf94@xxxxxxx>]

I dont recall which issue of QST it was in but there was a pretty good "here 
is how to do it" when something gets waterlogged.

I pretty much just follow that article...but the process starts (for me) by 
soaking the piece of gear overnight in distilled water...then I put it in 
IsoProp Alchohol for a day or so; let it dry then do it again.

I've had to replace some paper caps this way but so far I have almost 100% 
recovery.  Of course I havent tried anything that was in salt water....but 
that doesnt seem to be the case here.
