I just returned from the hamfest at Greenville, Alabama. Members of HODARS made the journey and had three tables. We promoted the club and sold some syrup. We always have warm home baked biscuits and warm syrup for folks to sample.

Greenville is a small fest, but lots of friendly people looking and buying. Our syrup sales were very good and HODARS is grateful to everyone who dropped by to visit and sample our syrup. The money raised with syrup sales goes to help our club and we appreciate the support.

The Butler County RACES group were very courteous and we appreciate the free tables at the hamfest. We will be back next year.

My thanks to KA4PKB, KG4CQZ, and KA4NDY for making the trip for the club.

My trip into Teletype RTTY

This blog author has been licensed as an amateur radio operator since 1984. I entered as a Tech Plus, but found 2-meters to be boring. I wanted to get on HF and see what was out there.

After my father-in-law bribed me with a Drake TR-4C if I passed my General, what the heck could I do but upgrade. Unbeknownst to me, my dear FIL was working on a big surprise for me. He had seen my keen interest in the assorted RTTY teletype machines in his basement shack. He had several different machines each doing a different speed (60, 100 WPM) and mode (Baudot, ASCII) I was always impressed that he could copy the news reports and he knew Hank Aaron had broken the home run record before it was reported on the news.


Dear FIL procurred an old Model 32ASR and began converting it to a RTTY machine. He built a homebrew TU and installed it. I call it old, but at the time, it was miles above the old Model 15.

I felt very special when I was presented with my new toy. I had a tape punch and tape reader on the machine. I kept about a dozen pre-punched tapes hung on the wall. These consisted of transmissions I used over and over, such as personal info, RTTY net preambles, etc. We lived in a manufactured home at the time, and often my dear hubby would hear the machine running as he came down the driveway. He would think to himself, "Oh heck, dinner is late tonight!"

I think back to these days often when I am at the W4HOD club station working a RTTY contest. Using a computer terminal and Writelog are really a huge improvement in operating and I enjoy them very much. But, in my mind, I like to travel back in time 25 years and remember the muted smell of machine oil from the machine, and the distinct feel of the rolls of teletype punch tape.

Here is a link to more detailed info on a Model 32ASR.

Okay, the OM wants to add someting!

Dave here, (K4ANU, a call I inherited from my Dad).

Just a few comments about RTTY.

I remember the whole end of the trailer shaking when that thing was running, especially when someone on the sending end forgot to turn off the diddler – that used to annoy Dad to no end. He was essentially an electronics engineer without the credentials. The TU he built was like a watch, a small box crammed full of stuff, worked like a charm. One day, Cheryl took the thing apart and, of course, couldn’t put it back together. Upon presenting it to Dad, in pieces, he rolled his eyes and said, “Keep that girl away from screwdrivers!” and this became a running joke. He was very proud of Cheryl due to her enthusiasm and fearlessness – taking stuff apart is easier than putting it back together!

I grew up around Amateur Radio and wasn’t overly interested in it as a result. When Cheryl first saw Dad’s shack (which, to me, looked like the helm of the Enterprise), she was fascinated and took to it like a duck to water, which delighted Dad.

Typically, when we visited my parents, Mom and I would go out in the yard (she’s where I got my love of plants ) - Cheryl and Dad would go down to the basement where the shack was.
He was licensed in 1955 ( I think ) and , of course, back then if you wanted it, you built it. There were tons of surplus equipment left over from the War, and parts were easy to come by. The trick was putting them together. I feel sure that some of the things he built are still working today. He was a remarkable fellow.

Although I rarely use it, I’m proud to have his call. As Dad used to say, ”All I need is a ‘s’ and I’d be K4ANUS!”. I think it’s ironic when someone sees my call and thinks, ”Wow, a K4A call, must be an old hand!” Not really…

Has it been this long...?


Here is Bill Gates Teletype tape which input the BASIC interpreter to the Altair computer. Notice the date is 2 March 1975. Gates and Paul Allen created the interpreter in two months and it fit in less than 4K of memory. Allen took the tape to MITS and discovered they had only one computer with 4K of memory. After loading the Teletype tape, the READY cursor began blinking. Everyone at MITS was excited. And so it began.

Despite good reviews from the computer hobbyists, not many were buying the operating system. It seems a lot of users were sharing their copies with other users, prompting Gates to send letters to all the electronic publications of the time that accused the hobbyists of stealing his software. Some things never change.
