Am I the only one doing this..? When I use CHIRP or UVMOD with my UK5. It cancels my request to flash and warns me I am in the wrong mode. I shut down disconnect. plug cable in and turn radio on. It now allows me to flash? If I hold PTT at boot it will not connect and tells me to swap modes before continuing. I've had no problems. I've flashed about a dozen times so far no issues. Did forget a few times in the beginning to update flash firmware and would have to start over again but no issues. Fun toy but I wouldn't put it to any real world test nor would I depend on it in a real SHTF situation. Remember use this thing responsibly. If you don't have a ticket I'd get one. FCC is back in full force with fines and confiscations. Good HT cost you under $200 Yaesu makes a few affordable HT's.
I was able to receive FT4 on 28.180 on AM using a Buddistick with the stock firmware modded via UVMOD. I'll try egzumer's fw and see if sideband is any better on my radio. It was still worth watching you try. Thanks for the video.
