Re: Marconi 2023A Signal generator
Jeremy... Today I fell foul of that Modulation On / Off switch....... Grr.. I set the generator for 145 Mhz, FM Mod, to test the new Demod board. Carriers and down converter worked well, but no audio out. The mute transistor was not conducting.... After a while I noticed the Modulation was OFF. I now have a card underneath the generator.. in FULL view... Check mod is ON
