This is as simple and straight-forward as it could be.
Let’s do it #
Press and hold down PTT and 1 while turning on your radio to change the bands on your Anytone handheld (tested on my D878UV+). To change them, turn the channel knob and power the radio off when it shows the desired limits.
But I’ve read on social media (Telegram) that some people were not able to change their bands – mostly users of mobile radios. In this conversation Arnold, OE1IAH shared his work-around for this.
He just changed the 17th byte in the codeplug file so the bands in the codeplug matched the bands used on the radio.
I use Linux on my computers so I usually have such tools installed already:
$ printf '\x03' | dd of=codeplug.rdt bs=1 seek=17 count=1 conv=notrunc
Why would you need this? #
You get a codeplug from a friend but you cannot load it into your radio because it uses a different band setting and you cannot change that on your radio. So you want to change the band setting in the codeplug to match it your radio setting.
But, what you still have to consider #
You change from 0 to 3, that means you can store frequencies within 136-174 MHz and 400-480 MHz while you use the 0 setting. You then change your codeplug to only make use of 144-146 MHz as well as 430-440 MHz.
You see where this is going?
You’d be fine if you only use frequencies within the HAM bands, though.
