Hi Dean, I don't homebrew batteries. That would involve handling more hazardous materials than I would be comfortable. I homebrew the maintenance and charging gear. My approach is not entirely unique

Could you give a bit more detail on the batteries and a link if possible? I was looking for a lightweight reasonably priced battery and to use a solar panel to charge them on my trips to the

Please review the following video before you do the calibration. As is stated in this thread, it is very easy to get it wrong, and then can be difficult to get it back to working. Since you have

I tried that, nothing happens...Checked with my friends on the Air, I find the freq out by different amount on different Bands. It is disconcerting. The receiver is pretty good though. Thanks

No, I'm just assuming that everyone can use the Arduino IDE with the GCC compiler. Those on other OS's than Windows can use one of their emulators and it should be fine for learning. Once learned,

I heard about that library, but haven't downloaded it yet. WIll have to do that. Jack, W8TEE

Jack, Teensy 4 - lots flash, lots of SRAM, fast processor, Where is the challenge in that? When I started on real-time embedded systems we had a memory and clock cycle budget for each module. I

Jack are you going to provide a compiler like some of the training books did years ago. I learned at Bell Labs Training center in Piscataway. I used a CPM Microsoft compiler at home to really learn

Hi Bob: Just about anything a ham might want to do can be done with "pure" C. Someone once said C allows you plenty of room to shoot yourself in the foot, and that's very true. However, C++ let's you
