Jason,
Something else you may want for your TX project. And It's FREE!!! I have a
brand new blower in a 19" rack mount cabinet. It is an adjustable speed dual
squirrel cage type. Let me know if you want it.

Look at fests and ebay for handbooks from the
early 50's to
r and more expensive.
It sure is FUN to homebrew!

I would like to have a copy of that article; for I
found an old homebrew transmitter recently that uses a
pair of 807s to modulate an 814. It needs a complete
rebuild, and I have not put power to it yet. The bad
news is that looks like it has been sitting in a barn
for the last 30+ years. The 814 h

I have always heard from all my

This is not to say you won't work anyone in your area with
low power, but if you hear someone at a distance, the 200
Watt + carrier can make t

A collection of old handbooks is a great thing to have,
both the arrl and the bill orr handbooks.
A 6146 modulated by a pair of 6l6's would be nice,
50 watts of carrier, 200 watt pep.
You can put a xtal in the grid, or build an osc stage
to isolate things a bit.
Or buy an old VFO to drive it.

That's exactly what I want to do. Low power using receive type tubes to
start with then go for higher powered building.

What power level are you thinking about?
What features and what is the modulation scheme?
I have a bunch of older left coast and ARRL handbooks that may have what you
are looking for. I may be able to locate something for you and scan it to
you.
