Heads Up: Expressions of interest B set antenna bases

[David Dunlop]

It's probably been mentioned before, but the B Set portion of the 19-Set operates on a fixed frequency, which back in the 1940's, was a wide open frequency. Today, that frequency is smack in the middle of commercial aviation traffic and off limits, even with an amateur radio permit.

Yes, you can squeeze the coil inside the set to change the basic frequency, but the B-Set puts out such a dirty signal (including an FM component), it is not worth the risk. The aviation world is jumpy enough now, without them detecting weird radio signals from a very old radio and wondering what's afoot.

If you want to have an intact B-Set in your 19-Set, fill it with dead valves. It will look great but do nothing harmful if accidentally turned on, and the main set and I/C will still operate.
