Updated (and final) Version of T41 book


 

All:

Al and I have just updated the 3rd edition T41 book. We moved the calibration info from Appendix C to its own chapter (20). The expanded instructions and new software make T41 calibration much easier. We have also updated the narrative in numerous places and have concentrated discussions on the V12.6 release where those changes are important.

Some of you are asking yourself: Do I need to buy this update. Truthfully, if you already own the 3rd edition, we would say no. Most of the important changes are discussed on the web site and photos and schematics are available there, too.

On the other hand, this is the last change we will be making to this book. Al and I have been at this for almost 7 years now and we're getting a little burned out. For that reason, we are turning this site over to Oliver King, KI3P, and Dr. Bill Schmidt, K9HZ. Al and I will continue to be active relative to the T41, but will leave the details to Oliver and Bill.

If you do want the final version of the book, its new cover looks like this:

The book is actually available now, but the Amazon ad will not reflect the new cover for about 10 more days. (If you order now, it will be the new version.) If you are attending the FDIM conference this May (coincides with Dayton Hamvention and the conference hotel is about 10 miles away), Al and I will be selling autographed copies on Thursday night (May 15th) at the conference hotel starting around 8PM. We have reduced the price of the autographed copies from $12,500 to $40...which is a deal and less than the Amazon price! If you have a previous copy of the book, bring it along and we will be happy to sign it.

This has been a fun project and we want to thanks the hundreds of people have contributed to its improvement over time. We hope that continues long after Al and I are gone.

Thank you for the 7 years of blood, sweat and I'm sure tears (or almost tears).? I'm still working on my v12, but I'll get there.??

Now, the question that I am sure is on everyone's mind, what's next (after the long vacation)?

Hi Greg:

Al and I are having dinner together tonight to talk about that very thing. I have a couple of add-ons for the T41 and I'll find out Al's plans later tonight. I also have a non-programming, non-ham radio book in mind, too.

I did want to thank you for all your contributions over the years...they have been invaluable!
