Tnx OM I will start checking! Tim

You can check the software to ensure that it didn't get messed up somehow. In BPF_Control.h, make sure that the definitions of the control words for those bands are OK: #define BPF_BAND_10M 0x0002

This needs to be verified with others, I get same BPF for 17 and 10M. 17M BP looks OK 10M it selects 17M filter bank. I was about to pull all the torroids off and start over, I had another BPF board

Jerry, I plan on building a new Main board with the regulators and heatsinks on the rear of the board so any heat from them doesn't go directly to the Teensy. I may try the switchers. My temp - ~42C

Robert, I think that is the best way to solve the problem. Kees, PA0KME

Just a little more free space. No difference in working. Kees,PA0KME

Kees, thanks for the input. I have a 40mm Noctua fan for the Teensy and a 30mm fan mounted on the heatsinks. Temp runs 41.9C to 42.5C. I noticed that you're running at 46.4C. I'm not sure that

*** I keep mine cool by eliminating sources of heat. I replaced the linear 3-terminal regulators with Murata switchers. No fan, no freezes. Can't hear any noise from them. Any noise is drowned out by

What happens with a 528MHz clock and smallest code? This seems a tad small. Jack, W8TEE

I meant version 50.2, of course.

Robert: Downloaded and compiled version 66.7 here. Works ok and no freeze. (Still clicks when tuning though.) What helped with me is keeping the Teensy cool. I use a small fan in Justin's kit. Without

I've had Covid three times now and the second one I used Palovid and it was wonderful. I should have had a prescription for this last round, but for some reason I didn't. Big mistake. Jack, W8TEE

Jack, sorry to hear about the Covid, Paxlovid is the only way to go, but you have to take it within a couple of days. I caught it at 79 and was feeling pretty good after three days, gone in 5.

Robert: Thanks for the offer, but I think we're okay. If not, I'll let you know. When I'm back on line, I'll let you know if I find anything that might be helpful. I feel badly it's taken this long,

Jack, thanks again for the help. Actually I already removed and reinstalled the IDE and everything else. I had a problem like this before and doing that fixed it, but not this time. Maybe I should

Robert: I wouldn't do it yet, but over the years I've had to reinstall everything from the IDE to the TeensyDuino to all the libraries. After doing that, it worked. I have no clue why...it just did.

Jack, thanks for the help. I'm still trying to figure out what has changed. All of the SDT Versions were working until I changed the position of the Temp display and compiled. There was a popup

The stack space is probably large enough here not to be a problem. The other version make me uncertain. My system is still in parts as Al and I are finishing up the last update for the book. I'm still

Jack, I recompiled SDTVer066.1_2-24_25 (Arduino IDE 2.3.4) unmodified(original config.h) with: Smallest Code with LTO 528MHz Serial Statistics: Memory Usage on Teensy 4.1: ? FLASH: code:208488,
