"TC Dufresne" wrote in message ... Hi: I am having a problem with a "Simple Receiver for Beginners". It is from a design that was featured in an old (1981) ARRL handbook. It is a DC receiver, looks like alot of fun, but it isn't fun now. Here is the problem. 1) No oscillation! I can't find it (the VFO) on my DX-398 receiver at all, or on my Radio Shack freq counter. 2) The power (+ side) electrolytic is supposed to be a 500uF, 16 volt. I am using a 470uF 35 volt. It gets really hot!! Short somewhere?!?!?! The VFO is REALLY simple, it has one transistor and about 7 other parts. I can't seem to see what is wrong, and I have tried. I would sure appreciate some Elmer'ing here! ANY help would be much appreciated. I have the above mentioned tools at my command, a multimeter, and an old Heathkit "scope. (which I really don't know how to use. It's a good idea to build things in stages, testing each stage as you go. Try disconnecting everything from the power supply and sort that out first. The capacitor shouldn't get hot. 73, Leon -- Leon Heller, G1HSM http://www.geocities.com/leon_heller |
