Hi Group,

Many thanks to my question about the 100MHz OSC, I did recall I asked
about
them a few years back. I was back looking at a RF down-converter for my
FRG-9600.

This was based on an article in Ham Radio Mag around 84 time frame. I
good ham
sold me a few of the crystals which have 100 MHz on them and the article
has
the circuit which should get it up to 100 MHz.

Anyway, I have a few volume controls which need to be cleaned, is there
anything over-the-counter which would do the job?

Tnx de KJ4UO
