So far real world results comparing the wideband tune and the single channel tune aren't vastly different. My neighborhood is a mix of hit or miss when I'm walking around with my Tidradio H3. I have certain "stations" I stand at and do my repeater testing specifically so I can do comparisons. Time of day and day to day make a difference in my area. I am in LOS but have at least 1.6km of heavy treed areas in the way. My repeater antenna is only up 13m at its center radiating point which puts it in the thick of the leaves. That night when I put it in I did notice the transmission from the repeater seemed a bit more smooth, meaning the background hiss was much more mellow and it seemed like better quieting. It is by no means anywhere near full quieting. I have my base station and I use a digital recording app to record my tests. And just like any night it will vary. I have tests that are LOS and testing areas that are not. Most of the tests last night were comparable to the last couple of tests except for my last station in front of my house. That one usually is nice and it cut out this time. I had other tests that are usually not so good come in better than usual. So like I said it varies. Today when my wife called me on the radio from the home base (50 watt, CA712EFC, 13m high) it came in much better than usual. That was one time and only about a minute of conversation. That too can vary from time to time. So far I can say that the single channel tuned is doing at least as good as the wide band tuned. Was hoping for better, but given my circumstances it's understandable that the 5 watt has a tought time getting through the trees. On the original duplexer I couldn't make it at all, I could trip the repeater but almost never get audio through. The wide band replacement usually gave me acceptable audio and the single channel tuned duplexer does about the same. I still need to do some farther out testing which I haven't done in a while. The goal is to reach my family one town down and that's going to take more height.

I'll just say that there are many flavors of the SGQ 450D duplexers out there and this particular one came directly from Btech and who ever they use to manufacture them. The original one that came with the repeater had the same numbers but it definitely wasn't made in the same place. The replacement they sent me and the one I purchased are the same. Thanks again for all your hard work tuning these for me Marc

Does seem odd. And not to quibble but asking people in the testing phase if they can hit it isn't going to be dragging the eff sea seas out to the site to employ hit men. Technically it's against regulation. But I'm sure every single one of us here has done a technicality that went against the regulation.

If it's a private repeater you don't need it.

Either way I was shocked.

I only did it once. So I don't know if it'll still be in the same spot if I went there again. I have to go back there in September... So it's going to be a while before I know.

That's certainly one definition of "business"

Welcome.

Define personal activities.

Just another matrix program, you aren't really even here.

Tropospheric Ducting as another way?

So you are here talking to a bunch of tech radio dorks and you think it's OK to be vague. OK.

Can't transmit into a repeater. Can absolutely transmit on ch 550-725

Something like this. It's on the cheap, but not $12 cheap. https://www.buytwowayradios.com/browning-br-400-assembly.html

The H3s are know to come in (new) as transmit defective. If you have a second one try that one. It will actually transmit a good couple hundred yards even though it's power output is very low, no where near the claimed 5 watts. Maybe reverse the tones and try that. You might be confused as to which is which. It gets me every once in a while when they use encode and decode instead of tx and rx. And definitely what SteveShannon said.

Make more. It's not going to end soon.

The MA09 antenna isn't all that bad. I found that mine wasn't really omni directional. We had a wind event and it bent the flimsy bracket I was using. When I used it while it was at a 15º tilt it was working better than it had in a while. I replaced the bracket and all of a sudden my signal went to crap again now that my antenna was vertical again. I had oriented it in the exact same direction because I have a cell phone booster antenna and I keep it pointed at the cell tower on the mast. I got this crazy idea and I rotated the antenna about 10º and reoriented the cell phone antenna and my GMRS signal got substantially better (from my house). Found that really odd that it made that much of a difference. Must have moved one of the lobes and now it's pointed at my house.

Ya, I didn't even use the cable after I saw what it was. I have the RT97S which is only 6.7 watt out of the socket and I think I had right around 2 watts at the end of the cable. Pretty pathetic.

I found a spot like that 17.5 miles from my repeater. Pretty much a foot either way and nothing. Amazing I even found the spot. And there's no way I should have even been able to touch my repeater with a mountain in the way. I know it's mine from the courtesy tone I use.

Yup, was too lazy to go look last time and couldn't remember. ends in 9 is 75 ohm ends in 8 is 50 ohm, right? Here's the roll of 50' I never used that I got with my kit. If I knew it was going to be this I wouldn't have ordered the kit.

That's OK, I cheated and used the internet to do the calculation. Put in a wattage and it spits out a dBm and you subtract the dBm's and there it is.

Well if he bought the kit like I did it came with 50' of RG59u (58?) which was horrible for UHF and the cable being that long.

They'll be a judge to sign a TRO in 3....2....1.....

He's telling me how I can use my repeater on the free airways. Schmuck.
