Hi,

I have quite a bit of info on this set, including pictures, circuits,
component layouts, model variants etc. Plus companion Tx, the T1154.

Hi,

Hi, can anyone tell me if the BFO freq on this set
runs at half the IF ie 280khz before I go mad
from Ron...

Yes, it does!

I guess they used the second harmonic to reduce the de-
sensitization that could happen if the BFO were at the IF
frequency and activated the AGC. It might also have helped to
reduce pulling of the oscillator by a strong IF signal.

A great receiver for its day although the build-state was
typical Marconi of the time. I think however, that the average
operation life of a Lancaster precluded the receiver ever
reaching old age.
