Recently bought a combination package of Radioddity DB20-G mobile with a GM-30 handheld GMRS radios. Both work as expected, as described but with terrible manuals, the need to download software from the Radioddity website, and get the correct drivers for the programming cable. However, the DB20-G does actually put out 20 Watts, as checked with both a Bird/Thruline wattmeter and a Surecom dual band wattmeter. The GM-30 is very similar to many other Chinese made handheld radios of the past decade, and looks a lot like my Anytone 878 handheld. However, the DB20-G fits perfectly in an old Honda Civic dash cubby hole, looks like it came with the car. A Tram dual band antenna went on the trunk. The TYT, Anytone,Radioddity radios appear to work well. I may do as a previous poster mentioned, and buy more DB20-G radios for use in other vehicles, and as base radios where I do not want a larger power supply and Motorola CDM or XPR series mobile dominating the desk space.
