Hi Jack,
Congratulations on receiving the February 2025 QST Cover Plaque Award for your QST article entitled "Solutions for Winding Toroids,? Four methods to make working with toroids easier".
?
You have presented several solutions on this reflector, and the Ham Radio community who reads QST liked the 4 methods presented in your article so much that they voted your article the most popular article in the February 2025 issue.? Great writing!
?
Thanks for all of your contributions to the T41-EP SDT project, and also for many areas in the HAM Radio community.

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.? Tim W4YN |

Which book edition??
Al and I released an updated version of the book, but we didn't feel it was worth calling it a new edition. The problem is I've placed two different orders and was sent the wrong printing. That has been fixed now, even though the ad has an April 18, 2024 for the release. There are two obvious differences that you can use to tell if you're ordering the right edition. First, the T41 on the cover should be black, as shown below. Second, and more important, if you click on the Read Sample button below the book image and scroll down, you should see that it has A new? chapter (Chapter 20 on Calibration). That chapter is new with the update and expands upon the information that was in Appendix C on earlier editions. Jack, W8TEE -- Jack, W8TEE |

Yep, Got the right version with chapter 20. If people look at the free sample on the amazon listing it shows the contents and chapter 20 is listed.

Re: No SSB output
¿ªÔÆÌåÓýI¡¯m not sure if this part was clear¡ but you should have jumper wires that go from the 90 degree pins on the MAIN board next to the processor up to the appropriate pins on the hat per the schematic (eg there is no other connection to those hat pins thru the Teensy).?
