In addition to what Artisan said, sometimes people, in good faith, simply misremember things. Maybe he was in a different magazine and, over the years...

@richpowers - if you want to generate an accurate and stable frequency, you need a reliable reference. That's where the crystal comes in. In some cas...

No, I don't think he was @richpowers. Yes, a frequency agile unit, whether it's some kind of PLL system, or a clock generator/DDS arrangement, needs a...

Just before I scratch-built my AMT3000 I was hoping to find one online, but wasn't interested in paying the crazy high prices they seem to be commandi...

@mark If it had been in a weatherproof enclosure with provision for balanced audio feed, with the 4-conductor cable to provide both power and audio, I...

Yes @mark - a big +1 to what you said about the cheap illegal Chinese FM transmitters. I purposely didn't mention them, because I consider the people ...

Wow, that's a new one on me @richpowers. I had always assumed that the crystals for the older Rangemasters were on the fundamental frequency, with no ...

So did it fit @richpowers?  

It's sad, but not surprising, if participation here is any gauge. There are just not a lot of people doing it. Most of us already have our transmitter...

Good to see you too @RichPowers. I've been busy with other things, but it's good to see the same folk still here, chattin' away about Part 15 matters!...

Got it @mark. The studio interface that comes with the Rangemaster is only necessary if you want to feed the transmitter with unbalanced audio. It has...

You totally can connect the output of the SW200 to a Rangemaster without any kind of a conversion box/interface, or whatever it's called. I've been ru...

It's definitely a tube type thing.

Pretty sure it refers solely to the DC input power to the final (PA) stage. That's the convention for such things. With the Rangemaster, when adjustin...
