All:

Greg pointed out that Amazon (finally) has changed the ad on their page for our updated DSP book:
Inline image
Note that the publication date is April 16, 2025. The bad news is that we lost over 150 reviews where most (85%) were 5 Star reviews. That will hurt as that's a good rating for a technical book. So, if you like the book, please take the time to write a review. If you don't like the book, go ahead and write a review...just don't send it in!

Re: February 2025 QST Cover Plaque Award

 

Congratulations Jack.? Thank you for pushing the league to keep publishing what I want to read.? If that last statement sounded selfish it was.? I hope I am not the only one.? When an article about what we want to see wins the plaque it reminds the ARRL that there are still lots of us that build and want to read about it.? Another benefit that is not as obvious is it shows people like us the league is still relevant.? I put off joining for years because I thought there was nothing for me other than a shiny magazine full of ads for Japanese radios.? After seeing several articles by Jack and others that I wanted to read I joined as a life member and wish I had done it sooner.? Sometimes I wonder if the league understands this enough but that is a very different topic.? That was a very long winded way to say again congratulations Jack on a well deserved award.
TX IQ Cal question

 

I remember doing TX cal on 4Sq kit and it seemed straight forward.
Believe we used CW mode back then.
Current procedure calls for SSB mode setup using internal 750Hz tone.
I can see results on SA and see changes while adjusting IQ, however my results look a bit different than in cal procedure pictures.
I probably need to work on SA settings to get display tweaked properly.
Just curious why we changed for CW to SSB.

OT cool new toy

 

I am teaching Electronics Merit Badge and did not want to take a lot of gear to meetings.
I stumbled on to this and did not really expect much but it turned out to be very nice piece of kit.
Much better quality than I expected. Best $100 bucks I spent in long time.?

Congratulations Jack, well deserved! It was a real treat sitting directly behind you last year at FDIM and wish we could be there again this year.
?
Takes a lot of work to even be considered for the Cover Plaque award and I am honored beyond believe myself ?to have two shiny ones of my own up on the "I Love Me Wall" here in the shack.
?
CU in 2026 at FDIM and Hamvention, adopting two 8-week old German Shepherd puppies radically changed our plans this year!
?
Congrats again!

Re: No SSB output

You can actually do either.? But do everything you would do on the outside of the radio to reduce noise¡­ like using real MIC cable, ferrites, etc.

I was thinking just bring Mic cable directly into Audio Hat.

Looks good though.

I have a lot of those connectors from RC control days!?

Here are my plans:

Run a shielded cable from Mic Socket direct to Audio Hat Mic pins.

Use back accessory IDC socket and run ribbon connector from there to Key inputs, Ground, and then a ground and wire from ribbon over to PTT in socket.

Tnx for that hint Dr. Bill. That should be a bit cleaner, no need for 1/8 TRS cable for Mic.

Cleans up busy side of Main board a bit. I will twist ribbon wires also per Dr. Bill.?

You also need to make a cable for the mic; Main to Audio hat

No it's there I missed it!
1. Make a cable to connect the ¡°R_OUT¡± (or Q) and ¡°L_OUT¡± (or I) and Ground (GND) on?
the Teensy Audio Hat pins with the 90-degree pins next to the Teensy board (pins 17,?
18, 19). The best way to do this is to use IDC jumper wires with female header socket.?
Twist the wires together for best noise immunity.?
