I wondered why I could send analog APRS transmissions with my Anytone 878 II UV Plus but not receive them.

I looked in the codeplug and found what I was looking for. 

There are two options to set. 

First, you have to click on Tool --> Options. In the following Window, you can set Analog APRS RX

I have uploaded the codeplug, and it doesn't work. 

In the channel settings I found another checkbox.

Now I can receive Analog APRS Messages.

The Anytone 878II UV Plus is a really powerful radio with a ton of features. But some of them are perfectly hidden.
