When the original UV-5R was introduced back in early 2012 and support was added to CHIRP shortly after that, the VHF band limits were VHF Low: 136 and VHF High: 174. This provided a STEP compatible frequency range from 136.0000 - 173.9975 MHz. This is why CHIRP is currently considering that 174.000 is "out of supported range".

It was recently realized that many UV-5R radios since 2014 have been shipping with the band limits updated to VHF Low: 130 and VHF High: 176 which provides a range that includes 174.000 MHz. It was just earlier this week that I submitted a patch that will update CHIRP to all this newer range. Once this patch is approved, the following CHIRP daily build will support frequencies up to 175.9975 MHz.

                I am trying to use a split frequency setup where I transmit at 174.000. I get an error that it is out of supported range. I changed the setting under other settings VHF upper limit to be aove 174 (175) and I still get the error.

 

Any ideas?
