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.

Any chance?
Thanks in advance,
Tom

Gotta be a short somewhere. Filter caps ain't supposed to get hot, and
yours is over rated to begin with.
