Radioddity DB20-G/Anytone AT-779UV RT Systems CPS Programming software

[WRYS709]

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!

I have converted my GMRS Part 95E code plug to the new RT System software.

This code plug allows the user to "open" their DB20-G or AT-779UV and yet restore full Part 95E compatibility and restrictions

Cool! RT comes to the rescues once again. I'm just curious of what problems they are talking about with the cable? My OEM cable always worked flawlessly. From their site, "For a long while we could not get into this radio for programming only to find out the cable that came with the radio was not right for that purpose."

RT Systems is referring to how the OEM USB cable, while wired correctly for the purposes of the radio communicating with their CPS software, was not properly wired for the purposes of reverse engineering how their software communicates with the computer.

I figured out the eccentricities of Radioddity's  own program. It actually works fine. When you set CTCSS/DCS tones, you also have to change the squelch method as well..

I'm assuming you didn't try it in GMRS mode.  It seems like it would be most useful for people switching back and forth which requires reloading all the channels.

 

I reset my Anytone to US-GMRS, and downloaded the radio into RT Systems for you to view and even use the attached RTS code plug, as you desire:

Actually the Radioddity software, for free, is very versatile; but is very limited in capabilities for: import, export and copy & paste.  So the RT Systems addition Is now very welcome!

As to your noted point, yes, once you use the Radioddity software to change Tones, it is helpful to change the Squelch setting to match as well.

Unlock the radio and then you dont have to skip 8-14. plus you can add the ham repeaters as well as police and fire for monitor..

I haven't switched my DB20-G out of GMRS mode yet, so I should only need to read from my radio if I get the RT software.  But wouldn't the default (factory) channels automatically be restored when resetting back to GMRS mode?  I know any extra channels I had added would be gone and having a backup of that would be the reason for using the software, whether it's the RT Systems or Radioddity program.

Yes, it automatically restores the basic 30 channels. 

You should do a backup of your current library of channels now using the Radioddity/Anytone software and again when you acquire RT’s software. 

Then you will have the ability to easily restore your library of repeaters/settings, etc

Rather than overwrite my code plugs as I modify them, I just save a new file with date and time. This way I can always go back to an earlier code plug, if I screw the new one up for any reason

Using channels 8 through 14 on a mobile is somewhat controversial as a violation of part 95E rules

The reason being that you are transmitting higher power than was intended on these interstitial channels very close to repeater input channels

Not only that but having a radio that can transmit on ham and GMRS is non-compliant.  That's why I was referring to switching modes.  I wish they would change their stance on that when we have both licenses, but that ain't gonna happen.

[SvenMarbles]

There's not much of a controversy.. You can be a "good boy" for literally noones's sake, because nobody cares, FCC included. Or you can just get on with having a radio that services you better..

[amaff]

Or you can do what I do

I have 8-14 programmed in with transmit off selected...but know that it can be enabled pretty quickly through the menu in a pinch

Are we worried about a field search of the FCC police? 
 

I wonder why so many people running LMR Motorola aren’t so skiddish,.. Or nearly EVERY gmrs repeater setup, running on Motorola. All type cert scofflaws.. 

If you have your Gemers license, and operate on the gemers frequencies, nobody cares….

[UncleYoda]

"NOBODY CARES" is not correct.  It's a secondary offense, like being pulled over for speeding and then getting a ticket for not wearing a seat belt.  And me and lots of other hams (and I assume some GMRS licensees) do try to follow the rules even when we don't like them regardless of whether we expect to be warned/fined.

No, but I did agree to follow a set of rules and generally speaking I like to stick to that unless there's a real good reason not to.

It’s not in any order of offense, because it technically isn’t even law. It’s FCC rules.

My mistake for using language that was not clear. 

I would hope that this thread does not get bogged down in the “FCC Rules Police” debate.

As noted by some, there are easy ways to open these radios and yet keep them operating within the structures of FCC Rules. That is their power, versatility and abilities for such a bargain price!

Let’s get back to programming questions about the RT Software for these versatile radios

Sorry, but you can't have both services on the radio at the same time if you want to follow the rules.  There was some guy at FCC a few years ago who said even having the capability to transmit on both using VFO (like a typical open UV5R) violated the regs.  I was surprised at that, but reprogrammed my radios, and bougght a GT-5R that was limited to ham.  Never did find any final word on that.

And yet, you took time from your busy day to repeat your point when nowhere did I say anything about “both services!”

[UncleYoda]

You did say "open" though, and and the frequency range specified in the instructions includes both.  Open is widely used to mean more than just locked to one service.  (Don't worry about how busy I am - I'm watching the show in DC.)

Last time I checked your Ham Radio license is still active until 2030 and and you are coming dangerously close to Randy's definition of a "sad Ham!"
