This may sound odd to some, but this is an experience I had.
After correcting some common mode current problems, RF locking up the raduino, my next issue was exactly this: broadcast across all bands.? Before I finished building my BCI filter, someone (outside of this group) suggested I try just reflashing the firmware.? This was quick and painless and did the trick.? I am no longer getting broadcast across all bands and I still have not completed my BCI filter.
The thought process on this was that the RF may have caused some corruption in the NVRAM of the arduino.? Whether that was the case or not, it did resolve my problem.? Which makes a lot of sense to me (a computer guy) because I was having this broadcast issue in two locations 200 miles apart, so I did not understand.? The real test will be this coming week when I go the cabin and try again.
