I grabbed the Tin Ear docs too...I think I will try to build this little
receiver from my parts pile.

I need another receiver like I need a hole in the head but what the
heck...looks fun.

Agreed!

Paul,
That tin ear is perfect... That is exactly the PTO I was looking for. I'll
give that one a shot.

Thanks for everyone...

I prefer building stuff out of my junk pile. I do get a greater feeling
of
satisfaction when I can dive into the pile on hand and build something
that
works.

It's more fun that way!

Point taken.

But my goal at this point is to build w/ salvaged parts from my mound
of
junk...

Brian,
Just by looking at that schematic, where would I stop building if I only
wanted the VFO to use on a simple transmitter?

I looked it over, and have a pretty good guess, but I'm not certain.

Thanks.

James,

I printed out the docs today....lemme look at it.

Good question...

I looked it over, and have a pretty good guess, but I'm not certain.

IMHO, it to me as if:
Q1 is the local oscillator VFO
Q2 is the mixer (it's the only xstr that gets anything from Q1;
because of capacitors C9 and C10, the bottom end of R3 and the
bottom end of Q3 are essentially at ground potential to RF)
Q3 is the RF amplifier
Q4 is the AF amplifier
Qrest are elements of a push-pull AF output amplifier

Cheaper, too. There's three dollars worth of parts there.
