Amateur Television – a beginning

Yesterday I went out for Chinese at lunchtime. My fortune cookie said “Begin…the rest is easy.” I hope that’s true.

Tonight I began the first step of getting on the air with ATV. I was sent a M369 TV Modulator by the fine folks at Cadco Systems. This unit should be able to output approx 10mW, though I haven’t yet measured it.

I’m feeding it into an M2 HO Loop antenna right on the workbench. I was able to receive a signal a couple dozen feet away. I consider this phase to be a success.

The next step is to get some amplifiers together to boost the power to 15W. At that point I have a lead on a high power amplifier that I can build that should be able to get me up to around 400W sync power. I also need to find a 32V power supply.

More to come!

I'm starting to cook up some… Continue Reading

For as long as I’ve been involved in amateur radio I’ve wanted to get into Amateur Television (ATV).  I just never seemed to have the money to get started. Now that DTV has made NTSC Television more or less obsolete, there is starting to be some surplus equipment available.  I suspect that more and more… Continue Reading
