Details:

Tunes by means of a convenient tuning knob on the front panel. Here is some info I was able to pull up on the internet about this model: Heathkit q multiplier kind of device that must be used appreciated. The receivers crystal could be set to peak desired signal and qf-1 null an adjacent. This q multiplier is top quality all the way through.

This is a 1958 Heathkit qf-1 q multiplier. Cabinet measures w x. It provides an effective q of approximately 4,000 for extremely sharp peak or null. Appears to be working as far I can test it.

It is simple to connect with cable and plugs supplied following instructions in the manual. Comes with the original manual and layout map, as well box which even has postage stamp on it from 1959.

A tremendous help on crowded phone and cw bands. Can be used with any am receiver having an if frequency between 450 and 460 kc, that is not ac-dc type. I hooked it up to a Heathkit ar-3 receiver and each setting seemed change the am signal was listening.

The qf-1 may be used with a receiver which already has crystal filter to obtain two simultaneous functions. I'm listing it as for parts but theres a good chance is in perfect working order. It obtains its power from the receiver with which is used and requires only 6. I'm not an expert and that's about as far I can test it.

The peak or null effect of q multiplier may be tuned across receivers if band pass so its operation is more flexible than that a crystal filter.
