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:

1$ printf '\x03' | dd of=codeplug.rdt bs=1 seek=17 count=1 conv=notrunc

Why would you need this?

In Austria many of us use the website The codeplug for a Anytone radio had the bands set to 0 while some OMs could not change the bands on their radios so the CPS did not let them write the codeplug to the radio.

With this method you can change the bands in the codeplug so you can write the codeplug to your radio even if you did not change the bands to 0.
