Transmitters are to hams like an engine is to a car: you still have a
car without it, but you're not gonna do much! It takes an engine to make a
car go, just as it takes a transmitter to fully interact with the world as a
The transmitters presented in
this section are a cross section in time of the art of the radio
transmitter. They have always done the same thing: literally sending photons
across the street or across the world, to be received by someone and
converted from little bundles of energy into a recognizable audio signal.
What a great idea Mr. Marconi had.

Model 200 VFO
Globe Scout Deluxe
This is a
Globe Electronics HG-303. I found a NEW one
along with a NEW V-10 VFO. Amazing. This was
surely one of the last-if not the last-CW-only, crystal controlled
transmitters designed. The VFO matches the transmitter styling.
Harvey-Wells Bandmaster Deluxe Model TBS-50D
is one of my favorite transmitters. Very nice looking, and-with its

807 final, a solid medium power unit. It uses 2
6L6s in a Class B modulator. Manufactured between 1950-1955, it sold for a
list price of ~$112.00. The power supply is external to the unit, and it
requires an external VFO. Harvey-Wells made a matching VFO, but I have not
been able to obtain one-yet. Click on the photo for the 800 x 600 version.
This transmitter matches the
RA-17C, and appears physically identical to me.
Running 100mW output, it has the same 6 foot long 35mm film kHz dial &
Barlowe-Wadley Loop. All mode, it weighs 67 lbs! I like to think of it as
one of the world's heaviest QRPp rigs!!
This is a kit from the Italian
company, Geloso, I recently acquired on that
e-place. I believe it was originally offered in the early 1960's. It is
everything you need for a very nice 6CL6-buffered VFO.
Ought to make a pretty good QRP rig all by itself. I will probably set it up
with a 6V6 driving an 807-building in the ability to run it VERY barefoot
right out of the 6CL6 (or the 6V6-depending on who develops 5W output.)
