I am interested in building a FM Radio but cannot find a kit to construct. I am looking for a kit that has good selectivity on the FM band. Preferably one without any ICs but I can do with it if the kit has ICs. Does anyone know where I can find a good FM kit to build? I am reasonably new to electronics, but can solder and have a multimeter.
Also I am in australia, so if anyone knows of a good FM kit to build please let me know.
Ramsey has "some" nice stuff - however - you might wish to ask about support - if it isn't working when completed. A friend of mine bought a 220 MHz receiver. He built it - did everything properly - myself and another tech checked it when it was found to be very very insensitive. We checked the components - even swapped a few out - still no luck. My friend called Ramsey at our suggestion - they gave him a price - which was like double the cost of the kit - to service it - not to mention ship back.
The "Sensitivity" on that receiver - well - we pumped in a signal off a Service Monitor - at max - and you were just barely able to hear it. In my opinion, it was a piece of garbage.
In their defense - I bought some other kits and was very pleased with them. Sometimes a company will have a thorn between the roses. That receiver (IMHO) was the one of the thorns.
The other day - I seen in a Radio Shack store that I went in for the first time in almost a year - they have a pocket FM radio. I'm not sure that fits your idea of a kit - per your post - but maybe give it a shot.
"Graymark" (?) - not sure if still in business - used to make some kits. I built a couple of them in High School Electronics class. They weren't the greatest thing since sliced bread - but they did come in handy and worked.They also sold a booklet which I thought was pretty decent. In the manual for the "power supply" kit I built - if memory serves me correct, it had a place to show the expected wave form on a scope and a place for you to mark yours. I'll have to check the manual again - but it seems to me - that was the case.I "did" see one of their "receiver" books - but I didn't get a good close look at it to know how well documented it was. I believe it was an AM/FM radio.
CAVEAT EMPTOR - you don't want your experience to be a "bad" one. That is a quick way to sway someone away from this field/hobby. I don't know that as a "kit" - you're going to find anything with "spectacular" specs.
This is an ELENCO Kit. It is available in a version with solid state AF stage (AMFM108K) and IC AF stage (AMFM108TK). You can download the manual at
You can get them from many distributors e.g
I use the AMFM108K as practical work in our electronic curse for Ph.D. Students and it makes fun to them, even if the sound does not correspond to that of a HiFi receiver. The technology is that of the 60s. A AM/FM RF generator is required to align for best result.
