Any Hams here?

CW still ought to be required. Lloyd

An incandescent lamp isn't perfect, but works.

I struggled damned hard with CW. I really had a hard time with it. The fellow who did my test for General..I truely believe gave me brownie points to pass the code part of the exam. In fact..I didnt have a General, but a Conditional, as I was 250 miles away from a regular testing place as I recall so was given the exam by one of the Old Farts who worked with me on theory etc etc.

I was really into RTTY when I got my ticket. Cant be much of that anymore. Not with a Mod 15 printer and rolls of paper

The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie

And it wont radiate RF?

Antenna isn't quite tuned up right. :)

Some, but you can put it in a bucket of shielding to stop that (mostly). Lloyd

Sure, KD7HB. And I just passed the amateur extra test in November at age 73, so you can sure do it!

The closest I can come to that is remembering that I used a 300 baud modem when I started computing. I remember dot matrix printers, too. (I'll bet half the folks alive now don't.)

I recently bought a BaoFeng UV-5R portable radio and am in the process of learning about HAM. A buddy is going to help. (Terry, the same guy in San Marcos to whom I referred you years ago, who's doing the automating of some small SoCal manufacturing firms.) Anyway, until I take the Technician's test, I'm in listening and learning mode.

and that bucket of sheilding would be?

Now you may understand why I want a real honest to goodness dummy load.

Aw, C'mon Gunner! You 'passed' the test, right? You know what a Faraday cage is, right?

Put it all in a steel bucket with some grounding straps for the lid to bond to the body, and leave a little hole so you can see the lamp glow as you load into it!

Passed? Have they not included the basics, anymore? Lloyd

Traditionally it's a gallon paint can, with the RF connector in the center of the lid. The oil-filled Heathkit 'cantenna' was good for a kilowatt.

I still have a couple of them; first one was a Toshiba. I remember the manual (which I still have around here somewhere) went into great detail referring to the various escape codes that could be used to manually operate the printer over a serial/parallel interface, from printing actual letters to just pushing one pin out.

They don't do stuff like that anymore.

In the mid 80's I worked on the dot matrix inventors' next project, a four color ink jet printer that could build up a 3D image from its molten plastic ink.

"It wasn't long before someone had the idea to build three dimensional (3D) models using the same idea."

The idea was obvious to us from the ink stalagmites that accumulated on test stands and prototypes, but for several reasons that machine was very restricted in the height it could build up -accurately- and we were too busy trying to make it reliable to waste effort on most of the crazy things we knew the plastic-spraying ink jets could do. Plus the ink had a low melting point and poor properties other than looking good on the page. jsw

I seem to remember that there were programs for the cheap appliance computers (e.g. the Commodore VIC-20 or something like that) which would display and send RTTY when connected to a receiver and transmitter. A lot more portable (and quieter) than a Mod-15. :-)

I certainly remember them -- various speeds and sizes of them, too. ;_)

Good Luck, DoN.

Even better -- mount it in a gallon paint can, with a good RF connector in the lid -- and oil inside to carry the heat from the lamp to the walls of the can for cooling.

The higher the frequency, the more that lamp will differ from the proper impedance -- with all those little curly Tungsten wires as the filament. But the can will at least keep the RF from radiating. The main risk with a poor impedance match would be damage to the final of the transmitter.

Anyone ever have a Heathkit "Cantenna"? Was it an array of carbon resistors in oil, or an incandescent lamp? The former would be more constant impedance, at least.

Good Luck, DoN.

There are programs to use a PC to send and receive morse code that are freeware. There is also hardware with a microprocessor that decode morse code for about $30 from China.
