It's a ham radio thing. Claude's ham radio call sign is F2FO. Here is a YouTube video. http://blog.makezine.com/archive/2008/01/make_your_own_vacuum_tube.html

Here is a home made tubeless tube by Nyle Steiner whose call sign is K7NS.

The good old days of home brew equipment! communicate with something you build from ground up, I was just looking at the first CW radio I built, what memories of the fun days learning from every project, and sharing both success, and failures with other Hams.

Tnx for the memories

A Very Merry Christmas OLD Man Santa

In ham radio Old Man is a term of endearment. In Morse it's shortened to OM.

All guys are Old Men and women are either YL's (Young Ladies) or XYL's (Wives, or ex-Young Ladies).
