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.

It's all been covered before buddy, I know in the UK it's a no no to power up the B set. Mine will be isolated at the switch so it cannot be powered up ��

The none working variants of the bases I produce still take the antenna, they just don't have the PYE connector in the base or the link wire. Everything else is as per factory, in fact you could later render the none working ones working if you got the correct fittings etc etc.

I am interested in two working units as well please! If it is not too late..

If it's not going to be powered up its better to get the none functioning variant... The hole etc is still present in the base but the PYE connector is omitted. The base can be unscrewed from the isolator.

It will save me making link wires and searching out connectors and clamp bars.
And it will save you money too !
