Good morning DoctorWho

It is possible if you make sure that your London modulator only produces
a signal at the London channel. To make this you need a good RF-filter
at the output.

You have to split the signal from your London modulator to get
an input for the Birmingham mixer. Then you must add and ampliefy
the signals.

I stopped the development because there was no interest.

My idea was to put it in a little battery case with a 9V block
and put this into the coax cable in front of the antenna input of
the Birmingham set.
The current consumption is ca. 10mA so it works more than 10 hours.

What kind of modulator do you use at the moment?

Kind regards
Darius
