If you can't change the band edges on your Anytone radio, change the band
|
|
setting in the codeplug.

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.
