Greetings de N0GRM

 



 


Many thanks to those hanging tight to complete a QSO
with me using my 1929 Vintage TNT transmitter!


Two type 10 Tubes





 

Cleaned up the 29' transmitter.  After the mid December AWA event I'll rebuild it on a nice board.  This has been a gas - a great way to learn how the vintage transmitters work - I figure about six months of collecting parts and tinkering around with it to get it air-worthy.

Here's the link which was my main inspiration:
https://www.prismnet.com/~nielw/tnt/tnt.htm  I utilized two type 10 tubes.

I also needed to build an HV power supply - which I'll share photos when I have time to take them.  Basically it puts out 525dc, 7.5ac and 5.0ac 

This all started with a book I bought at a Hamfest about vacuum tubes.  

Note that the key shown is only used for tuning - there is also one on the desk next to my other rigs, along with a DPDT antenna switch.


History:

As a kid, my folks were friends with a family where the Dad was a Ham. I remember being intrigued by all the dials, meters, lights and his straight key. Although I never saw him operate it, or even have it on, it remains one of my earliest memories of the hobby.

I've always had an interest in electronics, especially radios. I took apart the family phonograph while in kindergarten. While growing up, we had a cabin several miles from the local dump where I was a regular Sunday morning visitor. It was a gold mine of discarded radios, TVs, clocks and other items (never identified and probably containing carcinogens) which supplied me with toys to be tweaked and played with. I'm sure you can remember back in the 60s' when radios were in wood cabinets and their schematics pasted inside the back panel. I learned how to read schematics by following the circuits and associating the parts with their symbols. Somehow I managed to figure out how they worked, what tubes were inner-changeable (and not!) and what NOT to touch when the radio is plugged in. Looking back I don't remember much parental supervision.

Zip past college to my carrier as an Electrical Engineer, where I've been designing hardware and writing software / firmware since the late seventies. Back in the early days programming was without the aid of a PC - that's another story to be shared over a long rag-chew. In 1985 a couple of Ham engineers encouraged several of us to get our ticket, and as a group we enjoyed the hobby as a group for a few years, until the company we wored for went closed shop.

Modes back then included CW, PACKET, SSTV, RTTY and some SSB.

Today, my favorite mode is CW, via Vibroplex bug or straight key when operating QRP. I enjoy being in the our doors and always bring either my KX1 or KX3 camping with me.  When at home I sometimes work side band for some variety, participating in contests or to listen in when not sitting in front of the radio. I even have a circa 1959 Collins 75S-1 Receiver in my office upstairs setup for some "easy listening."

Many thanks to those who stuck through a long rag chew - my favorite. I've made manyfriends via CW, and love picking up where we Ieft-off from a previous QSO. Looking forward to chatting with you again down the log!!

Installing myMosley PRO-57-B, note the contraption attached to the center of the boom. Either end can rotate up - moving the other end of the boom along the tower. This allowed me to install the elements with out assistance.
