Yeah.  Who is writing the CAT control?

And soon I will order jackAl for it (orders are closed now).

I have some questions though..

Is it better to wait for an upgraded jackal with a new teensy?

Also, does JackAl provide both audio and serial cat control through USB connection (teensy can emulate more usb devices when connected to pc.. bit I don't know if it is supported with jackal fw)?

What a great bunch of new projects. Congratulations!

Authors always amaze me. Some can write more books in their lifetime than a person could read in theirs. In this case you have more projects in one book than I'd probably have time to build in years.

The projects look like they have found a good balance between being pure software projects and actual hands-on electronics construction. Providing both software and circuit theory education through building them.

Maybe the ARRL will up their data rate and publish you book a bit sooner. (We could hope.)

Re: Book TOC

Jack, W8TEE
 

Thanks, Robert. Without the usual publishing pressures, this was a fun book to write.

Some of you have written privately about the Table of Contents. It is as follows:

0. Foreword
1. Introduction – Which µC and Installation and Intro to the IDE
2. An Overview of Arduino C
3. Libraries and a Gentle Introduction to Object Oriented Programming
4. Displays – 2x16 LCD, TFT, OLED, Menuing system
5. High-current Utility Power Supply
6. Mini Dummy Load with Power
7. Morse Code Tutor
8. Unique Programmable Bench Power Supply

9. Antenna Tuner
10. CW Messenger

11. DSP Post Processor
12. DSP Mic Processor
13. Signal Generator
14. Constructing the “Luggable Double Double” Magnetic Loop Antenna
15. Remote Control for the Luggable Double-Double Mag Loop
16. How to Make you Project Look Professional

The problem with the new Teensy (T4) is that its small size forced some of the I/O pins to be moved to the bottom side of the board. That would entail a total redesign of the JackAl board because we use a lot of pins on it. Some of the JackAl functionality is separated out into projects in the new book. JackAl is probably more cost effective, since it combines that functionality into one board, plus add features we don't cover in the book.

Re: Antuino Can it measure the RF Output Watts

Thank you all very much for your knowledge, which is very much appreciated.  We've been using it for antenna construction and its made life so much easier and quicker to say the least. Totally understand about the power input levels now and will look into your ideas for the attenuators.

At 28/11/2019, you wrote:
I would use an RF tap, such as the one here: http://www.ad5x.com/images/Articles/Tap50dbRevA.pdf
As Raj has said, a power-sinking attenuator could also be used. There are many dummy-loads with monitor outputs available, many from commercial installs such as repeaters or cell stations. I have one that will sink 250W continuous all day long and has a 40dB monitor port.
You could also use a directional coupler, as was suggested, but getting one with a flat, calibrated coupling would be costly. I have a few different ones, both home-brew and commercial (but hobby-grade) and the coupling can vary by a few dB even just in the span of the HF bands.
