I have always heard that objects I.e. other antennas, should be horizontally spaced at least one wave link away from operating antenna. So with that, your concern would be with your CB antenna. At 27MHz you would need about 17 feet of clearance from other objects. GMRS antenna would need around 2 feet. Now how critical this is to radio performace, I have no idea. But if you Google the subject, you’ll find lots of theories

Good evening folks! I've often heard many of your comments that we should have a get together and I figure why not? So I wanted to put some feelers out there on what kind of get together we should have. Should we reserve a table at a restaurant? Maybe a pavilion in a park and bring our own food (cookout or potluck)? Also, when should we have it? I figure maybe sometime in the late summer or early fall. Let's get some ideas together!

They should not affect each other significantly.

How do you unlock it?

I have a CB antenna and gmrs Jpole antenna on the same mast 3 apart. Will the two antennas in close proximity to each other lessen radio transmitting power? Will one radio bleed over to the other radio while transmitting?Only one radio will be transmitting at a time. My gmrs radio is 20 watts and the CB is 3 watts. Any help is appreciated!

@SvenMarbles what firmware is that? I have completely different results on power output in the 460s

You're likely right. I just put an RTSystems package for a newer Yeasu radio on my W7 machine and it did exactly the same thing as the OP's setup. All their other software has run fine under 7. After RTFM/system requirements, I realized I had to put it on a W10 machine to locate/load the driver and program the radio.

The MXT500 programming software requires Windows 10 or 11 OS.

I'm suspecting that whomever just does not make a driver for an ancient OS that was pretty much win95 minus DOS underbelly. literally no one, save maybe the embedded industry, still develops for XP

The GD VirtualComDrive does not install on Windows XP when I install the programming software. Under device manager I get a yellow icon indicating an error and when I install the software, the system tried to locate the MXT500 driver but fails. I know that this is a really old version of Windows, but the machine is used for programming old radios that require Windows XP. The serial # of the radio begins with 25. Any help would be appreciated. Larry

LOL, yeah, there is that.

I’m not sure I follow. Firstly, rescue from what? As far as I’m aware, only explicit military targets were targeted, and pretty surgically.. Secondly, I think you underestimate the Persian people there.. They’re actually pretty capable and educated.. I’m sure they’re not for want of all of the Baofengs they need..

You’re a ham radio guy. Enjoy it!

That's just what they do around here. Its the only way to find out who the smartest one is!

I searched through the archives and found this thread: Does anyone have any experience with using the Rugged Radios Suction Cup Antenna Mount? Suction Cup Antenna Mount – Rugged Radios This picture is almost identical to the set up I would like to run.

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 tough 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

This is a great hijack of a thread

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.

I've sent them back and I'm going to try the UV-17r Pro GPS. CHIRP does support it.

A guy on YouTube did a different radio with similar software and it wasn't anything he input, it was some preset codes. All that aside, the radio wouldn't work with the software for programming so I've returned them and I'm going to give the UV-17r Pro GPS radio a try. It's CHIRP compatible.

This is the kind of detailed real world data that's useful.

That’s only true if the only people who use it are operating under the owners license. If any other license holders use it then it must identify. Obviously that’s not the case here because MrSig has asked if others can check and see if they can access his repeater. But I don’t understand why anyone would go to the expense to add a Repeater ID to their repeater but not have it actually ID their repeater.

I Would Have To Disagree. Think His Story Has A Crack In It..........

Okay folks... Leo sent me a new SGQ-450D duplexer. We gave this one a tune-up and it's looking good. I am very impressed. First, I swept it while it was factory tuned. It looked really good and if it was mine, I probably would have left it alone. On the transmit side, we had a good notch removing the receive frequency at almost -80dB. On the receive side, the notch looked even better at -85dB. Leo asked me to see what I could squeeze out of it, and I have to say, I am impressed with how well it tuned. On the receive side, we got the transmit frequency notch out -95.5dB. On the transmit side, I was able to notch out the receive frequency -95.5dB. Very well balanced. I recorded a quick video of the sweep showing notching as deep as -100.2dB, which is fantastic. The video demos the benefit of a hi-res VNA (mine goes to 1024 points), the sweep results, and the SWR at power. On the receive side, I was at 35 watts, but when I switched frequency to demo the transmit side, I forget to turn the power down. That SWR reading was at 50 watts, even though I said 35 watts. I really hope this helps someone on the fence about buying a B-Tech repeater or the SGQ-450D duplexer. @LeoG, can you share your opinion on the real-world results?
