Re: No SSB output
V12 still relies on an external audio amp. Jack, W8TEE

It is good that the ground is in the middle, because you can easily flip the connector if you end up with I and Q channels reversed.
Another thing about the audio adapter is that it was not involved with the receiver in the original T41.? I'm not sure about V12. T41EEE.9 uses the Audio Adapter's headphone output for receiver audio, but that is its only involvement in the receiver. Also interesting is that there is a 2nd audio adapter device instantiated in the code and it has associated commands.? These commands do nothing.

Re: New book
Thanks for the purchase...You did get the right version, though? I resubmitted the entire book yesterday (after spending 2.5 hours talking with Amazon/Kindle), which is not good because we lose the favorable reviews. They still don't know what went wrong. They say the new ad copy should appear in a week to 10 days. Jack, W8TEE

Re: No SSB output
¿ªÔÆÌåÓýTim, ? Oliver is correct¡ if the audio hat + software is working¡ you should see a audio-like waveform on J17¡ which is the generated I/Q output to the RF board.? You can trace that back to PINS 1 and 2 (I and Q) on the hat.? If you don¡¯t see anything there to ground (and its about 0-200 mv), no sense going down stream to the RF, BPF, LPF etc. until that works. ? ? Dr. William J.

Thanks Jack. The automated message from Amazon told me to keep the old book and they would send a new one :)...I wonder if they will send a new Old one.
When the New new one arrives, I will write a nice review. Thanks for the great work!

Re: New book
Yeah, I did too, but twice received the wrong book. I have redone the submission from scratch and I should be hearing within 72 hours. It will have a new ISBN number, which means we lose all of the nice reviews we had up until now. To all those who took the time to say nice things about the book, a huge Thank You from Al and I. I will post when the new book is ready to ship. Meanwhile, they have been good about taking books back. Jack, W8TEE

Strange, as I waited until the purchase page had the new cover with the black T-41.
