[Elecraft] OT: Silicone sealer

[Peter Albright]

Owners of Kenwood TS-440 rigs are painfully aware of a problem caused when
OEM potting goop on the VCO board absorbs moisture. The goop starts to
conduct and the rig stops working. It takes hours to pick the goop out with
dental tools.

The recommended replacement? Hot glue or nothing, as recommended earlier
here.

The acetic acid kind comes with a Cushcraft antenna.

This stuff dries on the outside first (duh) but that means

the inside can stay wet for years.... I got that on mine.
