With the current firmware and v2.02 of the Radioddity CPS software, Channels 31-54 should be DIY.

With the latest Radioddity GM-30 firmware and version 2.02 of Radioddity’s CPS software, Channels 31-54 become DIY! oh rtfM… never mind!

Do you have the latest firmware?

Background: I have no personal experience with the Retevis Ra-25, however I do have much experience with the Anytone AT-779UV and the Radioddity DB20-G, both of which are clones of the Ra-25, with the possible exception of how CPS software is implemented and which is not relevant to your question. I know of no way to adjust the microphone gain on these radios. However, some have suggested that the small mic hole above the 2 & 3 keys on the Mic may not be in proper alignment with the internal microphone and that by opening up the case, this can be adjusted. Since I have no reports of low audio on either of my two of these radios, I will not be opening the microphone case at any time soon. But if you are so inclined to do so, let us know how it works out for you. NOTE: Perhaps this is a secret feature of the Ra-25 and not the other two. If that is the case and you discover a solution again, please let us know.

Where is the soldier in that photo?

I second those comments: Radioddity has had a much more expensive 40 watt GMRS mobile out for some time, that I felt was too expensive to consider. Now it seems that they have replaced that offering with this one for only $180, which to me is still a bit high for the premium of going up to 40 watts, but sure beats the price of their older version. In the interim, I went for the DB25-D when it was on sale for $194 as it is still 18/20 watts, but also includes DMR capability.

OK, thank you both. One reason I never purchased the UV-5G(X) was they were always sold in pairs. I see from the Amazon link, it is not really the style of the UV-5G(X) and appears to be an upgraded feature set.

Thanks for that tip: it works on the Baofeng UV-13Pro, which is the Ham Radio version of their UV-15 (and transmits on GMRS and MURS as well). It shows I have V06.01.014 for that radio and no, the Radioddity CPS software for their GM-30 is not consistent with this radio (I have the Baofeng CPS software and now Chirp supports it) and I would not attempt to put Radioddity firmware into this radio either.

Do you have a link where to purchase this radio solo and not in a two-pack?

@OffRoaderX just posted a video about this radio in the last few days.

I'm waiting for the DB100-G!

Is there a tutorial that you can link those of us unfamiliar with snakes on how to take your file and execute it?

Let me check… yes, that was my thought!

I would have thought your plates would say: RWC 280

Could you link the "Radioddity Bluetooth dongle" for me, please.

Good to know! Thank you

I don’t know: try it and come back and post the answer!

Yes, unfortunately, the manual is too brief, but there is a large user base of these radios given the large feature set and the relatively low price. Many of us have two. And as you note, many here are willing to share their knowledge with others, especially newbies. So you have already discovered that if you hit the FUN button, it opens up the MENU at the bottom of the screen. There are 1 through 30 MENU items available here, but as you scroll through them, some are missing due to the Part 95E certification for this GMRS radio (and are only available if the radio is "opened up" from its GMRS restrictions). You can scroll up or down through these MENU items by using the V/M key as UP and MAIN key as DOWN. As you discovered, MENU Items 1 through 3 set Tones, either Analog CTCSC or Digital DCS; and Item 1 sets the Transmit Tone; Item 2 sets the Receive Tone and Item 3 sets both the Transmit Tone and Receive Tone to the same value at the same time (sort of a shortcut from having to use Item 1 and then Item 2). I recommend that new users only set the Item 1 Transmit Tones required to access Repeaters and leave the Receive Tone set to OFF. So yes, you may hear stations or repeaters off in the distance that you may like to avoid, but, if a mistake is make with setting a Receive Tone, you will hear NOTHING! So better to hear too much for now. Here is how Menu Item 1 works: The Default state is OFF; no tone is sent. If you hit the MON button once, it turns on the ability to set an Analog CTCSS Tone, starting with 62.5 and using the UP Arrow Key and Down Arrow Key to scroll through all the available Analog Tones up through 254.1. If you hit the MON key a second time, it opens up a non-standard ability to create your own CTCSS Analog Tone, which I recommend that you do not use. If you hit the MON key a third time, it opens up the ability to set a DCS Digital Tone. There are two types of DCS Digital Tones: N (Normal) and I (Inverse) and most repeaters that use DCS Digital Tones use the Normal Tones. Using the UP Arrow and DOWN Arrow Keys to scroll from 000 to 777 in the "N" Mode and if you hit the MON Key a fourth time, it allows you to scroll DCS Digital Tones from 000 to 777 in the "I" Inverse Mode. Hitting the MON key a fifth time will circle around back to the default Tones Off again. Once programmed, push the FUN button again to exit the Menu. NOTE: Once you program a channel, either manually or with the CPS programming software, you can change the Tone for a specifically programmed channel using this method, but once you change channels or power the unit Off and then back On, it will default back to the programmed Tone. Good luck and enjoy a great little radio!

It is the remainder of the frequency for your receiving frequency and transmission frequency: after the "462" and "467" respectively There are only 8 GMRS repeater frequencies, so typically they will list: 550, 575, 600, 625, 650, 675, 700 or 725

Maybe they are John Candy fans...

I got the “ham radio” version of this HT, the UV-13Pro for $20 from AliExpress with free shipping and its open to GMRS. i like its “tone scan” feature and I retired my TYT-88UV Chirp recently added the 13Pro

That’s the problem with responding to “Guests:” They have no skin in the game, and never have to come back to these posts, once they are registered members.

That’s because I was responding to a Newbie, and you’re not a Newbie.

Welcome to GMRS and this forum. Some of the other members on this forum, have levels of intelligence so great, that a newbie question literally makes their brains explode! Don’t take it personally or as an insult. Some still like to Elmer, to borrow an expression from Ham Radio, that is, who enjoy imparting knowledge to those newly arrived to GmRS, and are not frustrated by answering similar questions, many times over. it is surprising, that those with such great levels of intelligence, have still not figured out how to go on to the next topic, without having to give any response. Part of the problem is social media software, that grants points, awards and likes and Dislikes to those that just cannot filter their impulse to “spray” every possible comment with their “scent. Now, as to your question, many HTs label GMRS as Channels 1-30. The first 14 channels are on different frequencies However Channels 15-22, the high power channels of up to 50 watts) are also the same frequencies as Channels 23 through 30, respectively, which are then used in pairs to transmit to, and receive from repeaters. So yes, the repeater output on Channel 23, is the same as a simplex operator on Channel 15. But they may be licated so far from each other that they do not interfere with each other. But you may be located at a midpoint where you can hear them both. Also you may be hearing User-A on the output of a repeater on Channel 23 and then hear User-B’s output on the same repeater but you are hearing them on the same frequency, denominated as Channel 15. It will make more sense as you get more usage experience
