Hi Trevor,
Good to have you back on the Forum.
Thanks for pointing that out. Yes indeed the waveband 3 covers 1,2Mc/s to 2.75Mc/s.
That's working fine as is Band 2 which covers 5.8Mc/s to 13Mc/s. It's Band 1 I'm having trouble with, squegging and all sorts of strangenessness going on. Before I do any tinkering with the RF and oscillator circuits I'll check the heater voltage of the frequency changer valve. It looks a bit dim.
The set has been fitted with a non Eddystone spec main dropper resistor.
Heater and HT currents pass through this component.
Not a nice arrangement.
