It's just 1 dB, not significant and you won't know the difference in the operating distance.

I think LMR600 has lower loses, a bit larger than LMR400, and I think it's not much more expensive either. The loss at 450MHz for LMR400 is 2.7db/100 feet. The loss at 450MHz for LMR600 is 1.7db/100 feet. For somebody who needs to run between 50 to 100 feed of coax stepping up to LMR600 would makes sense. The chart frequency of 450MHz is close enough to GMRS at 462/467 MHz the extra loss at the slightly higher frequency isn't that significant. For 50 feet of LMR400 at 450 MHz the power loss would be about 27%. For 50 feet of LMR600 at 450 MHz the power loss would be about 18%.

I thought that my Kenwood TK880-1 would be compliant on the 462 MHz Interstitial channels on low power but my recertified Bird 43 says it puts out a tad over 6 watts. I remember that my POS MFJ 849 said 4.7 watts last year that is why I decided to check this morning to see what the Bird would said. As for operating on the 462 MHz Interstitial Channels, you can operate wideband and narrowband, its your discretion. It's not just narrowband only, as per Section/Rule Part 95.1771(a) The Kenwood and Motorola portables and mobiles would be your best bet in order to be compliant with Part 95, Subparts A and E, and have the ability to program 70cm freqs. You will need to find the "R" model radio in the earlier models and the "Q" model radios for the later models in order to have the operating band range for programming the 70cm and GMRS freqs.

At a reasonable cost. There is better cable, various types of "hard line", but gets expensive real fast.

Antenna issue (suspected)- receive is excellent, transmission is lacking.

A friend con me in going to the HAM thing at DeVry University with him this Saturday and if you or your friend is going to this HAM thing I can bring the 269D with me and give to you or him. Let me know if that will work. -

Use a handheld connected to a base antenna in the 2nd story window. 5W gets to the 20 mile repeater just fine. Once I tried the low power setting, which is 1/2W. It still got through but they said it was a bit scratchy.

I'm jumping up and down giggling right now after opening your Pcalifornia.kmz file in google earth. My god this is better than I expected, and color coded for open repeaters. How did you compile this data? Do you work for mygmrs? I like the idea of having a kmz file for each individual state, also having a kmz file is better too. I use a offline maps platform called osmand which is ridiculously powerful and incredibly feature and rich, and nearly every single option, map display, etc is customizable. And it's all offline. With this KMZ I can import it into that so while I am navigating I'll be able to see the repeaters nearby visually, something you cannot do in something like google maps or waze. I'm just awestruck because this has absolutely exceeded what I thought of being able to do. If there was a (free) or "pro" paid feature in the mygmrs app or website where you can download the kmz file database by state, and it's updated and recompiled the same way the app and map feature is, it's something I'd pay for, and maybe a few others as well. Very interesting. Thank you for your insight! Wow this thread has blown up a little, I'm glad this is getting some attention and stirring up some ideas among all of us Thank you everyone!

You could save some money and use a lower powered radio. Wont need as big of a battery or a higher wattage solar panel. For instance my recent simplex repeater build has been running for a few weeks now on a measly 6ah battery and 10 watt solar panel. However my radio only draws 1.5 amps at 10 watts while transmitting, and .3 amps when idle. Here is the link if you want to see what i used and how it turned out. Might help give you some ideas.

I can’t answer your question. However, it took watching several YouTube videos for me to get my head into the right space/perspective to successfully use the channel wizard. Once I arrived, it was easy. Hang in there. YOU CAN DO IT!

Wouxan KG-1000g plus faceplate data cable
CALO50 replied to Gnarlykaw's question in Technical Discussion
As noted by WRYZ926, the sequence is a bit difference. Definitely use a standard cable tester and couple the OEM cable to your new cable build for testing. The indicators should light up like a normal cable. FWIW, the extension I made took 6 tries before it was of sufficient quality. Hang in there. YOU CAN DO IT! -
What is the principle behind the "ghost" antenna?

Wouxan KG-1000g plus faceplate data cable
WRYZ926 replied to Gnarlykaw's question in Technical Discussion
The Wouxun KG-1000G cable is not a standard straight through or crossover cable. Pins 5 and 7 are crossed. Here is the pinout for the KG-1000G cable 1 - 1 2 - 2 3 - 3 4 - 4 5 - 7 6 - 6 7 - 5 8 - 8 I will suggest getting a cable tester for testing. Here is one on Amazon that will test 6 wire cables with RJ12 connectors and 8 wire cables with RJ45 connectors.

In the meantime there's also the Towers 600. I've gotten responses out of it in my house in San Tan Valley with my Baofeng UV-9G. Both with stock and Nagoya 771-G antennas.

Be patient. There is a line of a gazillion people waiting on their request for the Towers 575 repeater.

Would like to know what radio you are using
WRXR255 replied to WRYD530's topic in General Discussion
HT: Lots of Baofengs. UV-5R's, BF-F8's. I bought lots of 10 of each kind when the rumor mill started up about the FCC's banning them. Those got a few of each sold off since then, not sure what my exact number in stockpile of each is currently. Need to pop over to the storage lot and inventory at some point. Bought a few singles of the 5R since then, some I had to 'jail break' with the three key hold/power on method. Not bought a single in a while so do not know if that trick still works. One Btech UV-5X3 - no idea on what I would need that extra band for, but I have it. I had bought a 5R years before all that to use at work. Figured out the frequency, the DCS codes and how to program it, and was fine for a while, but it was a drug... we all know where that rabbit hole leads... Soon after I dug deep into radio, and by proximity the HAM community. Started studying for my Technicians and General. Found the local clubs website and they had a test date coming up, and I e mailed the coordinator several times before then with some questions, but never got a reply. Guess they were just busy like everyone is, so was a bit put off, but let it slide. Showed up on the test day, walked into the room where they were having this shindig, Heard lots of chatter as I approached, but when I walked in, you could hear a pin drop. Before I could even ask if I was in the right place, someone said "Your in the wrong room probably..." I just said "Yeah, I definitely am." and left. Mobiles: Had one of Btechs very first mobiles and cant recall the model, with whatever mag mount they recommended. It got lost when my Subaru got totaled. Right now have a Btech UV-25X4, no antenna yet. Debating still on if its going mobile in my car, or I make it a base unit. I kinda live in a bowl so LOS is not good anywhere, but who knows. Will probably make it mobile.
