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](http://oe1iah.at) 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?

In Austria many of us use the website [dmraustria.at](http://dmraustria.at). 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`.
