Thanks Brian....005” is not easy to find, but I like the overall weight !! FYI...we just made our first lap around the globe today with a WB4ELK APRS tracker and SBS-13. Using call sign WB0URW-8.... 7

Mike, I’ve been using .005” music wire (not stainless steel) for the 20m dipoles. As for the 2m we usually use a .009” guitar string but on the -W flights used a insulated wire from a Cat-5 cable so t

Problem solved! Thanks to everyone and Mustafa. I have already tried other cables, yes that is also good advice. The root cause was too many libraries getting their shoelaces tied together and then fa

Looks like your device may not have a bootloader installed. Try using "old bootloader" to see if that works. _._

So here's the thing: I have programmed Arduinos before, but the lightAPRS fails to program. I'm stuck. In Windows Device Manager it correctly picks up Com21 as the USB port and I've set the various pa

James, the only misgiving I have with the pic implementation is that you are relying on this little pic to not get into a brownout itself. Using resistors, diodes, and opamps, and perhaps flip-flops i

Shane, Looks like we were replying at the same time. Option 1 sounds very feasible. I have some super low power PIC's that should be able to do just this. To make sure I understand your suggestion: Im

One more question --- The recommended setting for BOD is 2.7v. Since the code is set to stop doing anything once it gets below 4v anyway, suppose I set the BOD to 4.3 and raise the GPSMinVolt to just
