FM and repeaters on 6 meters? You bet!
There's not a lot to say about using the FR6 receiver once its been correctly built and aligned. If 6 meters is "dead”, it resembles the usual 2 meter action. If 6 meters is "hot", you’ll find an amazing variety of
Since the FR6 “hears” only FM, the various SSB and CW signals on the band will not be properly demodulated as to be intelligible.
This receiver is a good project for amateurs wishing to become more familiar with 6 meter FM before choosing a transceiver, or for those active on 6 who want an inexpensive receiver to take on trips, keep in a briefcase or to watch for band openings.
Most Ramsey Electronic Kits can be classified as "Skill Level 1" if we use the old Heathkit guidelines for ease of assembly. That means that our kits are intended to be successful for
Still, this
Before beginning the project or even studying the circuit description, it is worthwhile to develop some prior respect for how much receiver is packed onto the circuit board. The nine semiconductor devices (diodes, transistors and IC chips) give the equivalent of about 30 or more transistors diodes. And, in addition to four inductors, a crystal and two ceramic filters, there are nearly 60 capacitors and resistors. Surely, all that should result in a decent receiver! You could easily spend twice the money plus hours of time trying to gather the equivalent parts from catalogs and still need to make your own circuit board.
