Hello Rafael, what kind of "experimental license" do you have? to work in the frequency bands assigned to the "Radio Amateur Service" (see the ITU assignments) it is "ESSENTIAL" to have a Radio

And it's an American venture. That's good. "Oh, say can you 'C'...?" Bob — KK5R

Hi Bob: The book is a pretty complete introduction to the C programming language, especially as it would be used in a microcontroller environment. Rather than me trying to summarize it, you can go to

Hello IW4AJR Loris! I didn't know it was from another time, thanks for sharing it. Darrell Lee Advanced Data Systems, Inc. dlee@... 864-230-9626

Some of the old vintage radios and amplifiers are real hunks of steel compared to what we use today but never forget that we won wars with those old relics. Also, some are still used today; when I

There was no standardization in the old magazines! P1 stands for Potentiometer 1 nothing more! Come on ... a little imagination doesn't hurt !!! ... look at those scoundrels who made electronics 50

Hello Darrell ... But what do you want to expect from a magazine from 40 years ago? ... symbols and diagrams were often drawn by hand by inexperienced people then passed to printing without controls

Jack, please post a short/brief summary of the book's general features such as what it deals with and the goal of the book. This is for 1) those who would like to see what the book is about (that may

This gives more detail re the rheostat... Rheostat | Resistor types | Resistor Guide | | | | | | | | | | | Rheostat | Resistor types | Resistor Guide What is a rheostat? A rheostat is a variable

Yeah, I tried that too, but as you saw, the audio frequency changes from minute to minute. The carrier is constant. It's also stronger. 73, Mark

AGC systems are not difficult to figure out or implement. The math behind a useful RF AGC has been around for at least 9 decades. The Hycas system is just a modern restatement of older applications.

Some apparently thought that P1 referred to PI, as in Raspberry Pi, or the symbol used to represent a mathematical constant. 8-) Arv _._

Thanks Jerry, Concerning the tx, we are not working on ham bands. We'll use an experimental license (if it works ok without the SSB filter), in order to carry the wideband experiments. Rafael

I’ve used that method also, that works too. It also takes the advantage of taking the measurement down to audio frequencies.

I like it!? Simpler than the method I've been using! I tune to WWV, then hit the WWV Wikipedia page to see what frequency audio tone is broadcast that minute.? I use the WSJT-X waterfall to track

Gerard, I am not familiar with the multi-display modes.? I would assume that each has an I2C address that is configured as part of the Nextion programming.? This is guesswork on my part. I would

Evan, OK Look here, i like colors on the second Nextion An other tft file? https://www.youtube.com/watch?v=mFwCggew55Y https://www.youtube.com/watch?v=nZ-EF19BtWw My idea is to have main screen on a

Gerard, I have not built the SWR/Power meter into a uBITX, so cannot help there.? I have done the research on using two Nextion displays and found this in the past:

All: I feel badly about the font size error that occurred in my Beginning C for Microcontrollers book, especially since you bought the printed book before it was hardly even reviewed. As it turns out,
