For anyone that bought the Radioddity DB25 truck radio:

I've programmed it using CHIRP and the selection for the QYT KT-8900D radio as suggested on several sources.

The img file I have (USE AT YOUR OWN PERIL) | Onedrive link here | Google Drive link HERE | includes:

  • FRS
  • MURS
  • GMRS
  • WX
  • Marine (select boater channels and CG call channel)
  • The local stations/freqs provided previously in the thread in an img file for the UV5R+


All my programming is setup to show channel names, and scan all the bands (2x on the handhelds, 3x(less band D) on the truck radio. Be advised, all are running HIGH power (except WX) .

For this radio, I have presets for three channels (FRS13, MURS3, GMRS3) and the WX1PA7 weather channel on fist power up after programming in slots A-B-C-D. I can't figure out a way to lock these for every power up if that's even possible. It's set to scan M+A+B+C with a 15 second transmit response timeout or it rolls back to the A slot. (I think this is how it works: Monitored channel + the others) This keeps the WX channels that are constantly transmitting from being scanned - even though they are set to NOT scan they will lock on if the band is included - they do this in the handhelds I've setup. I also have Duplex=off on the WX channels so you can't transmit on them.

I still don't fully understand all the options settings in either the handheld or truck radio, but they're working well enough for my current needs. We used the FRS channels on the boats last week and everything worked great.
