  1. What's the make, model and type of duplexer? Duplexers always lose some power, I've measured losses like that first hand on the Jesai, Fumei and other Chinese flatpacks around the 6-7dB range which is exactly the power drop you're measuring. They're really only acceptable down to about a 7mhz split or bigger, not the 5mhz split we're used to. If it's something with a reputable brand name, it's not normal. a Celwave/Phelps Dodge or Telewave duplexer will have insertion losses around 1.5dB or so, if you take your time tuning those you can get that down to 0.8dB or so; if you get something like that the 42W you measured would be up around 35W after passing through...

  3. IF INSTEAD IH THE BATTERY ELIMINATOR YOU COULD CARRY YOUR CHARGER BASE WITH EXXTRA BATTERY AND Wouxun Vehicle Charging Adapter (CCO-001) (buytwowayradios.com) FOR THE CHARGING BASE!

  4. Michael, Thanks for the info... I'm quickly filling up all those memory channels with repeaters from locations I tend to drive near. I'm loving this 905G and am glad I went with such a nice HT rather than one of a lesser price/quality... thanks to all you guys who have helped out with all my questions. -RR

  5. While I don’t use a 70cm antenna for use on GMRS, I know from posts on this forum that some do. Technically you can transmit into any antenna designed for any band, but how long your radio will last doing so is a complete unknown. If your 70cm antenna has a sufficiently wide bandwidth as to present an SWR that is acceptable to you (and your radio) you can use it. An SWR of 2.0:1 or less is acceptable in many circles, including mine. Even some GMRS antenna manufacturers state their SWR is A wise thing one can do when transmitting into an antenna with a higher-than-optimum SWR is to back the Tx power down. Doing so reduces the actual amount of reflected power to an amount that lessens the probability of radio damage. I just now re-measured the Comet high-gain dual band antenna I use for amateur work and its SWR ranged from 1.6:1 in the 462.xxxx band to a high of 2.3:1 in the 467.xxx band. Your mileage may very.

  6. Unfortunately the attitude exhibited by some people doesn’t change until they personally experience the negative consequences of somebody else who feels the rules don’t apply to them. And even then they still might not get it.

  7. The OP mentioned using a repeater channel to talk to the other radio but has no repeater nearby. Also, the display shows a plus sign. That is because you are transmitting on 467.xxx mhz but receiving on 462.xxx mhz. You can not talk to your other radio on simplex using a repeater channel by default regardless of ctcss tones/codes. Switch to a simplex channel and try again with codes.

  8. Why do so many people come to my beloved GMRS and then try to find ways around the rules? Even if YOU dont like them or YOU think you are so special you need not follow them, those rules are what makes GMRS the best option for the two-way radio community that uses it. Maybe you need to be on ham, where they seem to accept out of the box ideas. Or maybe you need to join the yahoos on CB 6, where rules dont apply. But, I feel, GMRS is well crafted for what it does. I know you will never get caught but you could just accept our rules and be a good radio citizen.

  9. Many, but certainly not all, antennas are tunable. If you can find a 70cm antenna that is tunable, you can trim a little off the length to retune it for GMRS. As you mentioned, the wavelength for GMRS is shorter than it is for the 70cm ham band, so this is a relatively easy thing to do. Using a 70cm antenna without retuning will cause some of your power to be reflected back to the radio due to an SWR mismatch. How much so will very much depend on the specific antenna. This also may or may not be problematic depending on the specific situation. With that said, when I'm shopping for GMRS antennas, I try to find either GMRS specific or UHF business band antennas that are designed for the 450 to 470 MHz spectrum. They are out there and not too hard to find, but because they are less common, you may have to look in other places than where you'd look for a ham radio antenna. Buytwowayradios.com is one place I've found them, and theantennafarm.com is another.

  10. Yes you can have same repeater with any number of same repeaters with different PL codes. Feel free to PM me and we can talk...I have two 805G and 905G as well... Will share my config file so you can look at it. MacJack

  11. Wot- I actually did a little more research and think that when the time comes to upgrade my mobile power I'll just go with the Wouxun KG-1000G rather than purchase an amplifier for my HT... -RR

    KG-UV9G

    I purchased the Wouxun KG-UV9G Pro (SHTF) radio at the beginning of June and received it July 16. I had a couple of days to play around with it and change the programming a little before leaving on a long road trip. I have seen some comments asking why anyone would want all of the channels programmed with the Pro model. I am in California and live in the area of the Creek Fire last year. While CalFire does a great job, we don't get a whole lot of information when we need it. I had programmed a scanner with all of the Fire frequencies, all local and state LEO freqs, County public works, Utility company, Air, and Cal DOT freqs. During the fire (over two months) I kept the scanner on and my HAM radios on listen to local repeaters. I could hear the pilots of the helos and fixed wing aircraft that were making water and retardant drops as well as the pilot of the air control plane that was flying overhead and directing the drops as well as ground units. Many times I could information from what I was hearing before it was made public during two daily briefings. We were evacuated from our home for a week during which I could listen to see if the fire was near the house. We were some of the lucky ones who did not lose our house. When we returned I kept listening. The more frequencies you have to listen to the more information you can get. On to the radio. Obviously I appreciate the scan functions and the scan types. I scanned all GMRS simplex and repeater channels plus some repeaters I had added to the programming during my trip. I had it sitting next to my KG-905G which was scanning the same frequencies just to test the two radios. When we swapped drivers I would scan the raildraod frequencies that came programmed and heard a lot near large rail yards. I enjoy listening to that type of thing. The UV9G comes with AM Air frequencies programmed but I couldn't get anything on the radio even when I was in a hotel near the end of a runway of a major airport. I didn't take time to look up and program other known airliner frequencies. I will do that later and try again. I did scan all 800+ channels that were programmed at times and didn't hear much. As a GMRS radio the RX and TX are good. I need to do a little more testing but on simplex it seems almost as good as my KG-905G. I was able to hit the same repeaters on the UV9G as I could get on the 905G. Audio reports were good. I really like the level of water and dust resistance. The menus are somewhat complicated with a slightly steep learning curve to learn what the abbreviations mean but it is the same convention as the 905G so I already knew most of it. I like the size of the radio as it isn't too big or too small. The supplied antenna seems to work well. The 3200 mHa battery that came with the radio as well as the extra 3200 mHa battery I purchased both had no issues with the belt clip installation as reported with some of the batteries. I scanned for over 70 hours with about a half hour of TX on my trip and never had to change batteries. Some of the pre-programmed channels are probably not needed, but then again, when there is an emergency or the SHTF you don't really know where you will get good info. I purchased the radio and spare battery from BetterSafeRadio.com and they were great to work with. On their homepage they kept a running message of what order range they were working on which was much appreciated. Five weeks after I ordered the radio I went ahead and ordered the spare battery and after talking to them via email they made sure both orders were in one box so I would get it all together in time for my trip. The Wouxun programming software is minimal for the KG-UV9G like the software for the KG-905G but is sufficient. The same programming cable works for both radios. I am very pleased with the radio and BetterSafeRadio. For my needs/wants it is definitely worth the price I paid. Sean

    Family use of GMRS

    Everyone in your immediate family would all use the same call sign. You all have to ID with the call sign every 15 minutes of conversation and at the end of the conversation, regardless of the duration. You can add additional identifiers if you would like. An example would be, everyone in my family would use ABCD123, but I may ID my station as ABCD123-ALPHA. My wife would ID as ABCD123-OMEGA. My son could be ABCD123-BETA. Again, the add-on ID is optional... but legal. For what it's worth, no one in my family uses add-ons. We all just use ABCD123 and call each other by name.
