[HBR] Building an "IF strip" in a separate box

[Brian Ford]

There was in a 50's Hb a project for an IF strip board on a separate chassis,  54? maybe.  I often wondered what the full ranges of use would be to have such a device.

I have a chassis here that has worked well as a back end for various
experimental
front ends. It has two 455kHz IF stages, product detector, BFO, audio,
audio-derived
AGC, and power supply. The first IF stage is connected as a common grid
amplifier
so a low-impedance input is available.

This has worked out very well for investigating a few front ends, filters,
etc. The
chassis is much larger than it would be for a complete radio - adapted from
some
piece of $5 swap meet gear - but was very easy to put together, align, etc.

I think that building an IF strip is a good approach. The only trick,
perhaps, is how
to connect it on either end to the rest of the receiver.
