At long last... RT Systems has delivered their $25 (download) software for the DB20-G/AT-779UV mini mobile radios (Version 5.00.04). It orders easily from their website and installs easily into Windows (11 in my case) and works with my USB to RJ-45 cable. RT indicates that the delay to engineer this software was due to some "incompatibility" in the OEM USB cable wiring, but indicates that it works with the OEM USB cables. I suggest that they may have been using the original Anytone USB cables, which has Windows 10 and 11 issues. But both Radioddity and newer Anyones now have an updated USB cable (albeit it looks exactly the same as the legacy Anytone cable!). RT does sell its own USB to RJ-45 cable for these radios, either separately or as a bundled combo. It is currently only available for Windows 8 and above. I have imported my current codeplug into their software very easily, saved it and now will begin the process of exploring it capabilities. For years, I have kept a CSV (Comma-Separated-Values) file as a master list of all of those frequencies I want to use in some or all of my various wireless radios. It easily opens in Microsoft Excel and now with the RT Systems CPS software, I can "import" and/or copy/paste these channels at will. This software now plugs the major hole that these wonderful radios had since their release. My other minor concern is that they do not "tone scan" but a $22 Baofeng UV-13Pro Ham Radio took care of that problem for me. If anyone has specific operational questions, shoot them at me, and I will be happy to test them out! NOTE: There is another new thread on this topic that insists on using the "Technical Discussion" - "sort by votes" system of discussion, which I abhor! These posts are all about date relevance and I, for one, do not want to subject other's posts, to be "down-voted" and hence pushed to the bottom of the thread. This is radio technology; not a popularity contest! Enjoy!

As this topic comes up now and then, I thought I would summarize, again, how to expand the versatility of these inexpensive mini-mobile devices for use on GMRS: 1) With the power off, hold down the V/M button and turn the power on 2) Note the firmware version number and jot it down for future reference, such as "V3.0" 3) Note that the MODE is GMRS. Using the Up and Down arrow buttons, change the Mode to (136-174)(400-470) and turn off the Power. 4) Using the CPS programming software (I prefer version 2.02 of the Radioddity programming software which works on both radios), install the GMRS code plug attached below. You now have more control over the radio using the microphone buttons, as well as other expanded features, such as full 500 programmable channels available for many more repeaters as you travel. Enjoy! Anytone AT-779UV GMRS 202310130140.dat

After watching several reviews of the Radioddity DB20-G, I stumbled across reviews of the Anytone AT-779UV. Fundamentally, these appear to be the same radio. Indeed, there is a European version as well under yet another manufacturer's label/brand. Ironically, this AT-779UV was purchased with the understanding that it was a GMRS radio (according to the description). That said, what arrived today was actually ham band. However... Given the above, I am not sure this radio is considered Part 95e, so if completely legal is concerned, this might not be the radio for you and/or you can purchase the DB20-G. I am assuming the DB20-G is in fact Part 95e certified (I don't know). Again, the AT-779UV appears, for all purpose and functionality, to be an identical radio. That said, several of the videos showed an interesting (not published) feature/mod, which is reversible, to change the possible TX/RX frequencies and memory usage. Power off the radio, hold down the V/M button and turn on the power. You will be presented with a menu of radio configurations, one of which is 'GMRS'. Selecting GMRS, the radio has all of the same features (and restrictions) as the DB20-G (after reset/power cycle). Basically it behaves as a fully legal Part 95e radio. FWIW, I believe the aforementioned feature works on all versions of this radio, including the DB20-G. One of the other items in the menu opens up the radio to the full TX and RX spectrum and, most importantly, allows all available memories to hold transmit frequencies which, will in fact transmit. Again, the beauty of this mod/feature, is that it can be changed as often as you like. The only downside is that whatever was in the memories prior to the change will be replaced by the selected band defaults upon reset. For example, selecting GMRS, all memories are repopulated with the standard channels and the Part 95e restrictions. Set it to ham band and 144-148 and 430-450 gets a couple of simplex frequencies in the memories and does not transmit out of band. This radio is tiny but packs a lot for the price. For more information on the model in general, see Randy's review of the DB20-G (see link) Remember, the AT-779UV and the DB20-G are virtually the same radio. Both radios retail right around $100. Yes, it's Chinese, but IMHO, it's still pretty cool for a 15-18ish watt mobile (not the advertised 20W).
