Modulated - that is Posh!
Yes the 2nd conversion osc is very nearly the same circuit but it lacks the trimmer so pulling to exact frequency needs some attention.
Nice source of 10.7 crystals there - mine were extracted from gash crystal filters quite often.
Have just remembered Finglas also made a switchable marker box. I never had one. It produced 455kHz, 1.4MHz, 6 MHz and 10.7MHz maybe? About 8" x 6" x 2.5". But what was the type number?
