Of course these are FRS, but as modified being used as GMRS.

On your Radioddity DB20-G, try this: Turn off power Hold down the V/M key Turn on power Note the version of Firmware at the bottom of the screen; which version is it? The stock DB-20-G with updated firmware allows for DIY repeater channels:

And yes they do scan: Within a second or two of turning it on, switch over to Channel 22 and wait. It will then start a scan!

I used Hex Fiend on my Mac. I did not attempt to make any other changes to the Code Plug from there, putting the Hex Fiend modified CP back into the BF-T11 programming software to add the Repeater's CTCSS Tone. Do you think you can get more than 2 watts out of these handi-talkies?

Hey Jim, Welcome to GMRS and myGMRS! I don't have the Wouxun KG-UV9G Pro, so until someone with experience jumps in: Your question peaked my interest so I went to BetterSafeRadio's website to read about it and it sure looks like a sweet deal, especially as "upgraded" from UV9G to the "Pro" edition. Your use of the term "cordless phones" has me a bit confused with regard to SHTF frequencies*, but no mind. Looks like you are referring to one of these repeaters shown in this map: So, yes, all you need to know is the repeater frequency and on that channel in the programming and the tone that you need to use on transmit, to "open" up the repeater to hear you and retransmit your transmission. Are you changing these settings manually or with a computer? Here is a screenshot of setting up the SHG 550 repeater; note you must manually set the transmit frequency 5 MHz higher than the receive frequency. I thought this would be automatic, but apparently not so. I would not bother with receive tones for now, until you are sure that you are working the repeater properly. UPDATE: *Looks like they include the 900 MHz band cordless phone band frequencies, too.

Isn't the frequency hopping controlled by software?

Yes, especially the part about the underground bunker/condo built for millionaires to survive just about anything! And there are 3 vacancies available!

Pass it on to another family member or friend.

Ah, going back to their website (for the 115) one must scroll the photographs to see the addition of the removal cigarette lighter plug.

@Steaven78welcome to this forum! I would not get too worked up about this thread; it is old and has gone off course many times. That being said, the chart cited in @wrci350's post is a good up-to-date summary of the differences between FRS (unlicensed radios) and GMRS radios (which require a GMRS license). Just note that other than Channels 8-14, FRS radios can go up to 2 watts.

Given the OP's interest (in another thread) of using repeaters in Dalton City, IL and perhaps others (but not yours of course!), I would have to recommend away from radios such as the Midlands, which seem to embrace Narrow Band FM.

How prevalent are narrowband repeaters on GMRS? What happens when someone with Wideband attempts to use one of your repeaters? UPDATE: I did find these statements: GMRS Wiki Still curious: What happens when someone with Wideband attempts to use one of your repeaters?

Correct me if I am wrong, but both of those Midlands require direct connection to a 12v source and do not come with hassle-free 12v "cigarette lighter" plugs.

Is this what you are talking about: Cross Channel 2-in-1 Duplex Repeater Controller

About 5 minutes into the segment:

Radioddity DB20-G/Anytone AT-779UV +1 I personally do not recommend the Retevis Ra-25 clone, as reports here have shown it will not work with code plugs designed on the Radioddity/Anytone versions; many of them are published for easy usage. They are just so easy to use right out of the box, including programming tones using the keypad and hence not requiring a computer to program (although more sophisticated features will require computer programming).

I must admit: I have never proposed a split frequency shift for the 8 repeater channels of GMRS. You have me there! ?

WoW: and you criticize some of the things I like to discuss here??? Let's unpack this: With only 8 repeater channels available for GMRS you are proposing what? That the rules do not prevent split frequencies so that your repeater potentially interferes with 2 of those 8 channels? "You need to monitor both input frequencies..." - Do you mean you must monitor both the input frequency and the split output frequency? Sorry, but I am missing the advantage, if any, of this idea. But I like that you propose it here! ?

Of course! Why didn't I see that So long as it does not transmit digital on GMRS, what do we care??

Do you want our blessing using a business radio in digital mode on MURS without a business license (not that a license matters in that situation)?!? I could bring my Radioddity RD-5R to Albuquerque and join you! ?

Welcome! Check these out West side of St Louis: metro_skywarn/South O'Fallon St. Charles/575 and in Eoila Missouri and in Dupo Illinois I am not sure if they are active

Go drive over to your local Walmart parking lot and you will hear them; I think it is MURS 4 or 5.

You obviously never saw the movie: War Games!

Nice catch! I didn't read the full Sub-Reddit thread, so I do not know what time frame and context they are using the term war-driving. I tend to use it on this Forum when I go out finding GMRS and Ham Repeaters and reverse-engineering their tones to gain access to them. My original knowledge of the term comes from just after the 90's after Apple released their first Airport WiFi device (looked like a flying saucer, and then others followed quickly behind them) to go out driving to find both WiFi signals that were not protected (no password) or even to unscramble the poor quality of WEP passwords used in that era. It was called "war-driving" in reference to Mathew Broderick's character in the motion picture, War Games, and his use of his POTS-modem to war-dialing: find and break into different online boards etc. And the term was modified to the pursuit of WiFi discoveries by driving around. What is the context of war-driving to Amateur Radio that you are reading?

I thought there was less traffic on the 405! ?
