I thought that by definition a Moxon is only two elements. There are other antennas that claim to be three and four element Moxons, but a Moxon is just a specialized Yagi. Single band Yagis work by having a single reflector, a single radiator, and multiple directors. In most cases the directors are all 5% shorter than the radiator. Sometimes the directors taper so each is shorter than the previous director. Have you tried making your directors shorter?

He lives in Ramsay. In fact he just called me. I told him you were interested, Zach!

There’s a guy here looking at putting one up north of I-90 west of Ramsay. I will give him my support. Welcome to the forum!

It’s all removable.

In Chirp you have the ability to load all of the default GMRS channels. Would that help? You should also have the ability to import nearby GMRS repeater channels from Repeaterbook into Chirp.

Read it from the radio.

This is such a clear explanation that I actually mailed it to myself for future reference. Nicely explained, Marc!

We have done it both ways. Maurice has had both Intel and ARM based Macs. The first time I helped him I wondered how it could possibly work, but it actually works pretty seamlessly. He recently applied the beta of Sequoia and that broke the remote access software (RIM or Remote Incident Management). So he had to get another computer (Windows) so we could continue programming his several radios.

I’m not certain that’s the issue, although it certainly doesn’t make it easier. I regularly program several different radios using Windows programming software on a Mac. And I do it remotely to throw another wrench in the works. Marc’s post above describes the process I would use. Troubleshooting this kind of thing requires a logical approach, methodically eliminating non-issues while zeroing in on whatever is left. Make sure the serial port is being created. You can see it happen in Device Manager. Or you can see a yellow warning symbol if it fails. On a Mac the OS will sometimes intercept the request and ask if it’s okay. Device Manager will allow you to identify which comm port number has been created. In the programming software you must sometimes tell it which port number has been created. It must be the same as Device Manager reported. This is especially true when the device embedded in the cable is what has been identified. If the cable uses a USB connector on each end the radio has the usb to serial device built into it usually and can self-identify usually (except for an Alinco I have, which is stupid). Once you know the port has been created and you have told the CPS which port it is, the software should be ready to read from your radio. Always read before writing.

My understanding was not that they didn’t want people to check on their neighbors with a radio in hand, but that they didn’t want people mounting overly ambitious uncoordinated efforts that might interfere with the official efforts and taking additional risks to check on people, if by doing so they might have contributed to a situation that stretched out the already too thin resources. But instead of seeking to coordinate with the very willing additional volunteers they drove them away with their heavy handed tactics.

I’ve only used the Midland NMO mag mount. It is what I started with and I’ve found no reason to switch. But I do get a broken signal on transmit (meaning people report that my signal is broken) sometimes when moving on the interstate. Maybe it was just picket fencing. A friend recently bought a Comet magnetic base NMO mount (CM-5NMO) and it is slightly larger diameter, looks and feels well built, and appears to sit flatter. He and I have conducted tests where he is driving to the I-15 interstate, up over the continental divide, and north on his way to Helena which was the same path I had traveled earlier. Although eventually a weak signals prevented reception I never heard any breaking up while he was in motion. It’s a sample of one, so really only anecdotal, but it was noticeable to me. It’s not enough of a reason to dump the Midland mount, but if I were buying a new magnetic mount NMO, I would try the Comet this time. It’s about $33 at the usual ham radio shops.

Just push the button marked “Mon” or “Moni”. You might want to turn down the volume first. That’s exactly what it’s for, temporarily listening to a frequency with no squelch.

Welcome!

Then contact someone with a tower (ham radio club possibly) and ask for a price to place your antenna on their tower and your repeater in their building.

If the area is already saturated with repeaters, how do you plan to avoid causing interference by adding another?

Mount it to the metal roof of the truck instead of the composite roof of the topper. The radiating element will stick up above the roof rack.

The 2x4 antenna you already have is one of the best for multiple bands. Try it on GMRS.

He drives down the road operating at speeds up to 75 mph. The limiting factor is the capacitor hat on the ATAS mounted on the rear hitch. There are several videos featuring his VW GTI. His YouTube channel is called StealthGTI. Here’s the video where took the screenshot:

This would do it.

I think most people who use GMRS do so using GMRS radios. They are people who simply buy GMRS radios to use while doing other activities. I also think that a significant number of the members of this forum do not use GMRS radios, because they are the more like GMRS radio hobbyists.They are the people who learn enough about the radios to repurpose other radios. This forum’s membership is not at all indicative of most GMRS users. We are the users who talk about GMRS even when we’re not using GMRS.

I suspect Rich gets very little from advertising, but if you become a premium member, that's $50 that goes directly to benefit Rich and allow him to keep this place going. Plus, premium members don't see any advertising and never run out of reactions.

That sounds correct. Only channel 43 allows you to change modes. Channels 39-42 each display something else. Here’s what I found: “Test mode enabled by pwr down, hold func+F4 and power up/Enables CH39 to 43 to be selected. ON 43 hold ptt in and can then rotate selection knob to change the mode ie broadband TX all vhf and uhf frequencies. Release ptt to save. Power down and back on, radio comes on in new mode. also CH-39-42 is selectable shows 39= RF FW version 1.10, 40 = CPU V1.11, 41 lcd V1.10, 42 = mode:02 amateur, 01 fixed, 03 broadband unlimited TX.”

Read the one that’s already on the radio. You should always do that first anyway. Then look at what you want to change, which will be unique to your location. Change or add channels as needed and then write it back to the radio.

I bow to you, Gil!

Is there an AGC setting on the MXT275? Make sure it’s on. I doubt there is one, but on my radios that have it, it’s miserable working a mix of near and far people without using AGC.
