In reply to M0CGH:
Hi Colin;
Had a look at the circuit diagram for the MT, it has a remarkably simple receiver and seems to manage without any RF or IF amplifier stages, there must be quite a bit of low noise gain in the active balanced mixers.
Thanks to all for satisfying my curiosity, I am afraid I have a nostalgic interest in simple receivers as a result of building my first amateur band receiver which was a three valve TRF from a design by F.G.Rayer G3OGR in Practical Wireless some 49 years ago when I was a virtually penniless schoolboy.
Look forward to helping you christen your MT in the near future Colin.
