What limits the current in this amplifier? Something on Bill's amp board or within the rest of the T41? -Nate N8BTR

after reloading (TNX for bug fix Oliver) and recalibrating first Q is in log. 7 w SSB 20M unsolicited nice audio report (cheap home made mic) onward and upward! TNX to all the contributors Tim W4YN

No question that configuring the audio state is an important function.? I've used this method before, usually for things I didn't want to convert into a library or when linker support was deficient

I'm using a different meaning of the word "special".? The code in the AudioSignal.h file is the software heart and lungs of the radio. -- 73 Greg KF5N

Verified Bug is gone TNX Tim W4YN

There isn't anything particularly special about this code.? It can be placed in its own cpp file along with a header file for the global externs and function prototypes.? That's what I've done.

Yep...we're on the same page. Jack, W8TEE

Yes, Jack, you've got it!? There is some nuance when someone uses the term "global", and what I was trying to flush out was the "super globals" versus "local file globals".? When I see "extern" that

Mornin' Greg: Yes, Al and I found a lot of "dead" variables when we started out. We could tell by their names that some of them were clearly used as temporary debug variables that just didn't get

Great work Terrance!? That is what I aspire to.? It's going to take a few more iterations to get T41EEE that good. I wholeheartedly agree it makes it easier to find things specific to a particular

Found the bug -- it was a simple one-line fix in the end. Pushed to GitHub: https://github.com/KI3P/SDTVer066-9/commit/8569ee3bc37fdbb3143b00356bb0ae0507448c3a

Oliver - Thanks for update.? Your diagrams are very helpful. I took this approach.? Yes, it's tedious.? I've gone pretty far with my approach.? My SDT.h is only 209 lines.? This doesn't reflect a

Hi Jack- It's a metric of the reduction of global variables.? Note that the .ino file was also greatly de-cluttered in concert with SDT.h. There were also a bunch of variables which only existed in

Greg: Curious about the line: To get an idea of how much progress I have made, the number of lines in T41EEE.9/SDT.h = 1057.? SDTVer066-9/SDT.h = 2640. What was the impact if you add up the class

SRY My bad memory Spectrum Options Did we have option for averaging in older FW? Tim

Hi Oliver- One thing I recommend is writing a script to "de-globalize" the code.? I did this and removed hundreds of globals.? There were even globalized local variables! What the script does is

Thanks Oliver. This is a huge effort! And, very exciting! dave,n3ds

Oliver, success, I went back and re-flowed all of the connections on U15 on the LPF control board and checked continuity on all the pins again. Everything was ok. Then I remembered that there was a

I wanted to share a little information on how I'm going to go about restructuring the T41 code. The most difficult bugs to track down in the current code have been those caused by the radio being in

The Ver066.9 code doesn't have a menu option called "Display Options" -- which one did you select? [image.png]
