Two Stage Telegraph and Telephone Transmitter built by AB9ZG.
One of my antique radio friends built this transmitter some years back, a very true and authentic reproduction. I admired it at the time, not sure I ever worked him with it, but remembered it fondly.
Jon, the builder, kindly entrusted it to me as the caretaker, and looks like, given the weekend weather, I’ve finally got time to get it unpacked, tested, fired up, and on the air. Long, cold winter nights in Maine are ideal for radio.
I was therefore delighted to be contacted a few weeks by Jon, asking if I had interest in his creation. In any case, wanted to share Jon’s handiwork with my radio, and non-radio friends.
It is crystal controlled, you can see the xtal on the right of the upper deck.
The upper desk is the RF section, and the lower deck the power supply and modulator.
Ideally I’d like to find or build an old table so I can set up a replica 1920/30s station, complete with one of the early National SW-3 receivers.
I’ll post more as I get it on the air and operating!

Had a few minutes this morning to get Scott W9WFA’s old National NC-101X out of storage and onto the new 1930s station desk. I’ll be moving the other 101X over once the restoration is finished, but it’ll be on the workbench for a bit, so time to fire up something else.
Listening to 40 meter CW on the National NC-101X receiver with the green “magic eye” tuning indicator. Bands are pretty lousy this morning, much static.
Transmitter is a MOPA (Master Oscillator Power Amplifier) built by amateur radio operator AB9ZG, modeled after one of the early Aero designs.
CW “Bug” (keying device for transmitter) is an early Vibroplex “Zephyr” model built in New York City. Believe this belonged to my Elmer Dick W2UJR. “Cans” (headphones) are vintage Brandes “Superior” model, built also in New York City in the late 1920s or early 30s.
Antenna is a traditional balanced feed line 160 meter dipole up about 50’, right on the coast.
Photos on wall are of a teenage ham radio operator from the 1930s who lived in Kennebunk, Maine. The other of some young radio hams from Syracuse, NY in a home built ham shack.
