It's been a long time since I played with an Aerotron station, but
you have to remember that they are multichannel units - and there
are frequency select lines.
Motorola uses a ground on a pint to enable the appropriate channel,
and Aerotron may be the same. Look at the schematic (or trace
the oscillator section of an extra board if you don't have one) and
locate the select lines - you will probably find that they go to
sequential pins on a connector, and one of the other pins on that
same connector is the select line (either a ground or a voltage).
Once you determine if you have to tie the select line high or low,
then do that to the channel 1 pin on the connector and it
should work.
Then you can quote the famous line from Young Frankenstein....
"It's Alllliiiiivvvvve". "It's Alllliiiiivvvvve".
