This relatively new mobile DMR chinese radio has been getting mixed, veering onto bad reviews in a number of online forums but has also been getting some nice online (youtube) comments. I have been documenting MY adventures with this radio on my blog https://kd2wll.winstonlawrence.us. So if you want to know how to setup a codeplug for this and where and why the Retevis CPS fails (or bails) on you or Yes Virginia there really is an FM Radio built in... Take a look. Retevis/Ailunce HAS been improving the CPS software and has even updated the APRS so that it works with Brandmeister now (I've gotten text messaging working even before the update - take a look at the site -- but not yet tested the *new* APRS functionality and honestly may never do so since I'm not really fond of the APRS implementation from a cybersecurity perspective. Anyway '73 stay safe!
