I've been following this thread with interest; but sort of wondering why anyone would make a Command receiver into something it ain't. Unless you bandspread the receiver, the tuning rate is very fast for use with high selectivity crystal filters.
Look on the ARRL QST Archive and check out an article called "An ARC-5 Triple Superhet" from the late 1950s. This scheme works very, very well and the low frequency receiver can be used as a passband-tuning device.
Same basic idea was found in Volume 3 of the Surplus Radio Perversion Manual.

>Where is the screen grid bypass capacitor? I'm the original circuit, the screen bypass is the .1uFd on the bottom left, next to the 100k pull-down resistor. V1 is powered from the screen buss.
