I have two of the db20g radios. I like almost everything about it: small, easy to use, powerful enough.
What I don’t like is the fact that you cannot use Chirp or RT Systems, and the software provided by Radioddity doesn’t allow imports, and copying and pasting doesn’t work the way I want.
Also, this is probably the most frustrating: once you have a configuration file created, you cannot change the frequency range in the CPS to another, even if all of the channels you’ve programmed are well within both of the ranges. There’s a range of channels that goes up to 470 MHz. There’s another range that’s higher in the list of available ranges that goes to 490 MHz. A program file written for one range cannot be used for the other and changing the range in the settings wipes out all the channels you’ve created.
