I’m slowly assembling the Rx from QST 1966 originally discussed here
https://www.vintage-radio.net/forum/...d.php?t=195648
The original uses one single tuned circuit at 455kHz followed by a normal IFT. I wondered whether using an IFT in place of the single tuned circuit would improve selectivity, including it at shown in the attached PDF. Of course, the plan is to use ceramic filters in place of the two crystals.
I suspect there may be some subtleties lacking in my arrangement; if anyone could advise I’d appreciate the input.
