That was an interesting watch @mark. I didn't know that bass has to be center-panned when recording for vinyl, and am still trying to understand the s...
I'm not saying not to get it @richpowers. Sometimes these things can be fun to play around with. I'm mainly saying two things - 1) Discussion of the f...
It's a little hard for me to get excited about a transmitter that, in this day and age, uses a free-running LC circuit to determine the frequency. OK ...
That's interesting @richpowers. I bought my AM1000E from Keith in 2017. My modulation transformer is blue. I've been thinking about purchasing some mo...
I'm sure we here would love the topic of saving the AM band to be the talk of the town. Whether we like it or not though, the AM band is not exactly t...
That's a very useful link @richpowers. @jsh4 - I noticed only a slight increase in range when the soil was wet, but that's most likely because I don't...
However, I will say that the challenge in buying an old analog scope, is getting a good one. Older scopes, especially if going cheap, may well need so...
The first one only has a bandwidth of 200KHz @richpowers. To be effective for Part 15 on the AM BC band, you need a 'scope with a bandwidth of at leas...
I don't think that much of the internal circuitry on those crystal oscillator packages is available at the pins. Even if it was, the most you'd be abl...
It would be good if those crystal oscillator packages were available for a wider range of frequencies in the AM BC band. Every 10KHz channel between 1...
That's interesting @mark. Keith told me it is a Hammond 1590ZGRP123. I'm looking at the email right now. I've looked at the datasheet for it. It has t...
Thanks for this @mark, and I agree with very nearly everything you said. The only thing I wanted to question was your statement about the Rangemaster ...
If you're going to experiment with asymmetrical modulation @richpowers, it would probably be a good idea to invest in a modulation monitor, so you'll ...
Apologies for my reply not being more detailed or accommodating @carl, but I'm on my way out to meet a friend. Happy Holidays!
I see what you mean @carl. As for transmitter kits being legal, any transmitter that conforms to the relevant Part 15 regulations is legal, regardle...
