I see what you are saying, but actually in my use, they are not duplicated: When I am transmitting on Channel 15, I am transmitting simplex: both receiving and transmitting on 462.550. But if I am transmitting on Channel 23, I am using a repeater split: receiving on 462.550 but transmitting on 467.550. This gives me the ability to reach two complete different sets of people to communicate with. The same is true on Channels 16-22 as compared to Channels 24 - 30.

Why only 22 and not 30 channels? Oooops: which 8 more am I gonna get in trouble using?!? ?

Do you mean to change PL tone and/or High/Low power from the front panel (keyboard, yes?) to existing Channels in memory or otherwise?

@Papatree also has a couple of threads getting recommendations on antennas.

Thanks for tipping me off to Rattler's! How is the Wicked Chicken next door?

Rereading his original comment, I suspect the convo 118 miles away was through a repeater...

VHF will always outperform UHF outdoors given other similar characteristics: such as power output, antenna used, etc. I always LOVE to drive into a Walmart parking lot and listen to the rushed instructions given to their staff on MURS 5: Green Dot! ?

In another thread, I seemed to have engendered some argumentative replies to my suggestion that having a dual-band antenna matters when attempting to listen to marginal VHF stations. I will say that MY preference is to go with a good dual-band antenna for a dual band radio!

And/or MURS on your DB-20G's too! ? I have nothing more to say about MURS...

No mountains in between, so: GOOD! That chart is irrelevant as it ONLY includes GMRS with 5 watts; not your 18 watt mobile units, which are more comparable to Ham VHF 20 watts on your charts (although UHF at 18 watts will not be as good as VHF at 20 watts).

Once I am in the flats of The San Fernando Valley, the San Gabriel Valley or the Los Angeles Basin, I get steady clear conversations with the usual mobile picket fencing and various amounts of static depending upon range, etc. I use a $20 dual-band mag-mount and I am not sure 50 watts would provide much better coverage; although probably a better antenna would do that. What is the demographics of your mobile to housemate mobile location?

I just realized I answered your question with regard to my home base shack and not mobile. Mobile is always a challenge here in Los Angeles because of the many canyon passes that I drive, which knock out much simplex and even repeater coverage, depending upon my destination. I rather enjoy going "repeater hunting" or what I call "GMRS driving" where I go as close to a repeater as I can (sometimes even higher up, like at Chatsworth Peak) and scan the input frequency for tones used to get into the repeater (with my Pofung P15UV or TYT TH-UV88, both of which HTs can scan for CTCSS or DCS tones). When in doubt and no one is using the repeater, I can always utilize my OCD to manually go from one tone to another on my Anytone AT-779UV (clone of the Radioddity DB-20G) easily and give a quick PTT to see if a repeater exists: This is much easier on GMRS, which only has 8 repeater channels. I keep good notes and then see if I can hit these repeaters from home and make new friends!

Valencia, CA: how lucky is that?!? Be sure to stop by Dickie's and get some good BBQ! hahahaha

I seem to be blessed from my two-story rooftop: Historically, I had the original TV antenna up there rewired to my HDTV, so I would have OTA TV options to cable/satellite. I was able to watch in HD channel 24.1 PBS from San Bernardino, 64 miles away, until they moved their antenna some years ago. I still watch channel 24 on my DirecTV. So, using 146.52 simplex, I am always amazed at the coverage I get to the Southeast (shooting over the Cahuega Pass), East, and West, so far: about 45 miles. I was watching a similar Live YouTube video the other day: October 10th, 2021 | Simplex 146.52 | Long Beach, CA due South of me, over the Santa Monica Mts. I was unable to make an impression in its waterfall, but I started a simplex conversation with a Ham to the southeast whose beam was facing 180 degrees in the wrong direction and he made no dent in the waterfall either. But when he turns his beam around, not only did he come booming in to my shack, I could both see and hear him on YouTube! I also have had a good simplex conversation on MURS with a new GMRS friend also using a DB-20G who lives about 25 miles north of me, when he drove to a better "line of sight" spot to hit a GMRS repeater and then experimentally converse with me simplex first on GMRS Channel 3 and then a better signal on MURS 1. Hitting repeaters is very eye-opening, too; because of their height: Although I could not hit the YouTube video waterfall in Long Beach, I am able to converse easily on the Catalina Island repeater, 147.09, 26 miles to the south of Long Beach, which gives me wide coverage up and down the coast of Southern California. And, the Frazer Mountain repeater, 447.86, to the North, which is about 50-60 miles from me and even the Double Mountain repeater, 446.32, about 10 miles further north, which gets me wide coverage, including into Bakersfield to the North directly through the repeater (and not through a further linked repeater). And, the Santiago Peak CREST GMRS repeater, 462.675, about 50 miles to my Southeast, which gets me into San Diego. And the Chatsworth Peak repeater, 145.24, of the PV Amateur Radio Club, which itself faces west and gets me good coverage into Ventura County and southern Santa Barbara County.

Alexandre’s reinstated our MURS experiments! ?

Your so-called “common sense” has nothing to do with it when advising a Noobie Assume at your own risk.

Unfortunately aimed perfectly to any GMRS users up on the DISH satellite! ?

I use my existing rooftop Comet Tri-bander quite successfully on both UHF and VHF.

This link only gives me the Windows exe file noted in my screenshot above nothing else. Hence no Mac file in my download. I did not have a COM problem, but that may be because I was previously running some Windows software for my TYT-UV88 and had already linked my USB to the proper COM port, which cable was still plugged in, and it probably carried forward. I run Windows XP virtually using Parallels Desktop on my MacMini running High Sierra and have never had a problem with any Windows CPS programming software for radios that I own, or for Codeplugs that I have written for others, even for radios that I do not own. Here is the "default" codeplug from the downloaded DB-25G software: DB-25G-default.dat

I’ve been reviewing the SoCal Repeater chart for 6 meters

I DID IT!!! Now I see what I was missing... ?

what operating system are you using? wayoverthere's link IS to an exe file. I don't even own the DB-25G, yet I had no problem downloading the file in windows xp and showing you a screenshot of the running problem. I really want to help, but not clear what your problem is?

Could you be a bit more descriptive? Mine works, is a great radio, costs $99 new and yet I am missing "yyyyyyy"

And why do people keep buying these radios?!? How can I make my Anytone AT-779UV show "yyyyyyy" ?
