Hello Amin

I'm thinking of homebrewing a "tunable preselector" with a very narrow
bandwidth. If we can implant the Q-multiplier concept into the tunable
preselector, it should be very much cheaper than building one from a
combination of coroidal cores to get the best Q factor.

The idea is known as a regenerative preselector and there is a
lot of them on the net.

1967 ARRL HB had a receiver with an RF Q multipler.
