This is as simple and straight-forward as it could be.
## Let's do it
Press and hold down <kbd>PTT</kbd> and <kbd>1</kbd> 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 17<sup>th</sup> 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:
```console
$ 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.
