I guess the receiver sensitivity is what it is, but if you are able to receive better with the new duplexer that's real world sensitivity not theoretical receiver sensitivity. I get exactly what you are saying. And I'm pretty sure you know what I mean too. If I could hit the repeater at 5 miles and not 6. Then install the new duplexer and can hit the repeater at 7 miles but not 8. I would consider that an increase of sensitivity. But in reality it's the duplexer allowing the receive signal to still be heard while the repeater is re-transmitting and not causing desense.

More waterproof.

Yah, sounds like you bricked it.

That's what I meant

That's a good question, but not the way receivers get rated. The sensitivity is the 'receiver' sensitivity. A couple points about how the duplexer work and why the receive sensitivity isn't impacted. The duplexer filters out the receive frequency on the transmit side, and the transmit frequency on the receive side. There is no direct impact to the signal due to tuning. The only real 'reduction' would be the overall reduction in signal from insertion loss. However, you may see a difference/improvement due to the filtering for another reason. The cavity filters have a bit of a floating echo effect, with the dB of suppression wildly varying. Your duplexer, for example, floats between -85dB and -110dB per cavity pair. With a varying isolation of -170dB to -220dB. Prior to tuning, the duplexer isolation floated between about -45dB and -70dB. This can impact how much desense the receiver experiences, giving you the impression that receive sensitivity improved. To summarize, while the receive sensitivity doesn't improve with improved duplexer tuning, the improved filtering removing more of the transmitter signal and reducing desense, will allow the appearance of improved sensitivity.

You may want to do spend a little time watching some videos and researching on this site before making another purchase. Learn how to program repeaters and what limits you might be on the radios.

I guess another interesting note. I just turned both of the radios on again, I was able to get the HA1G to pick up one single transmission from the GM-30, immediately after depressing the PTT on the GM30 the green indicator light on the HA1G turns on constant and I can no longer receive a transmission until the radio turns off and back on again. Update: I can get the HA1G to rx from the GM30 all the time if I have it in scan mode, but once scan is off, then we revert to the whole no RX problem.

ASL (All Star Link) is right there too. ANd it's the ASL code that myGMRS was using. It's what Freedom Nation is still using. And the DVSwitch phone app will connect to a node directly with no server in between if you know what you are doing. I personally don't bother with any of that and just use MotoBridge since I have direct wireline connection to all my repeaters with it. In addition I have numerous other radios that I have full control of IE, zone and channel selection, front panel button access and control. All the good stuff. But, ASL, or even the old image we were using for myGMRS can be modified to be connected to with the DVSwitch app. My guess is it was never talked about by the admins because it would have been one more thing to provide assistance and support on if they were to have mentioned it would work. I have seen it work, I have made it work. I am NOT going to help anyone else with it. They can figure it out on their own just like I did or give up in disgust.

I did update the firmware on the HA1G. Maybe that did something?

I'm looking into the Wouxun KG-805G but if I wanted to look into the 905G model what do you mean by it has a bit better IP rating? and if I was to lean more on the KG-805G what program cable would I get I cant seem to find one for just that model on amazon.

I noticed that I am going to return it. I am looking at what few people have said though to look into the Wouxun KG-935G heard it is GMRS and a okay radio to start with.

You bought the wrong radio. Because it is a H.A.M.s radio, it likely will not be able to transmit on GMRS frequencies. IF it does transmit on GMRS, or IF you can get it unlocked, it is going to take multiple semi-complicated steps to program a repeater.. Good luck. ..you really did buy the wrong radio... UNLESS you bought the GMRS version, in which case if you did, you dont need to enter any frequenices - just pick the repeater channel, enter the TX tone, and talk..

so I ended up getting a Baofeng uv-5r just for something to practice on while I do more research on a decent one. so I got one without a program cable sadly. I am trying to manually set up my radio so I can transmit on it. but no idea how to do so I went on map and found a repeater I am close to. went and put in the frequency but that all I really know how unless I'm doing something wrong. please any help

Do a reset and you should be good after reprogramming.

Even though they don't call it GMRS in Iran this is the perfect situation to offer cheap disposable GMRS radios to the rescue workers to facilitate efficient communications.

You are correct it is the two lined version.

That may be the original 2-line display model. The ones I was referring to are the new full-color screen models.

Joined May 22, so over a year

I sorta reset my password. Used the same one. Was it a hack or just a glitch? Said it was a year since my last password update and it's mostly accurate. I didn't check but I got into GMRS about the middle of May and didn't get my license until shortly after that then signed up here.

Did you try to install the firmware again? Maybe it didn't go in right or it's faulty and a new one will need to be reissued.

Any of the Wouxun radios I feel are good. I like the Wouxun KG 935G plus. It ticks your boxes of nothing cheap, chirp programmable, mid tier. Since you want to use hiking it’s worth noting the 805, 905 and S88G plus are going to be easier to see the screen outdoors. As previously mentioned definitely stick with type certified for ease and simplicity. @73blazer listed a few things worth looking over in making your decision. Do you want waterproof? Bluetooth? … I know you said nothing cheap however something like a Baofeng UV9G isn’t going to break the bank, is waterproof and chirp compatible and a good radio to use while you determine what some needs or wants may be. In the end it’s your decision and I wish you luck in making it. If you are like some of us here it won’t be your last radio purchase

I have two of these db40-g radios with the exact same issue. e1,e2 code on power up. will update codeplug, will accept firmware update, but no beeps when knob is turned, just a little pop. no transmit and no receive. I have a message to radioddity.

lol... its ok, congrats to the winner.

I doubt Btech thinks that's a plan. They should mention it and might be able to sell an extra duplexer with each unit.

Had that happen to my H3. Was in a building and wanted to see if I could hit my repeater. I couldn't. It was strange cause I was pretty close by. Then I drove by it and still couldn't hit it. Somehow my tones got changed and all I had to do is restore them and bingo, success. It can happen.
