>>finally build, so
I've been checking the availability of some of the components in the UK.

>>1. Does anyone know how critical the use of 1N34A germanium diodes in the
circuit is? The diodes are in the ring (de)modulator for each of the high
frequency oscillators, used to determine the frequency difference between
the pairs of oscillators. Could I substitute silicon diodes of some sort
e.g. 1N4148?

I bought some not long ago from Cricklewood electronics in London. Theyre a
great store  because they have no minimum order requirement and carry loads
of semi-obscure semicons.
