It appear tapping and holding (long tap?) on each trace will bring up a menu of some type (format likely).

Once you figure out how to change each trace format it will be a walk in the park. I have the smallest(and cheapest) version ant it works well.

@chasedog1What type of duplexer are you trying to tune?

I think he is trying to tune a duplexer. The above video is as step by step as i could find. It uses a smaller VNA than he has, but the basics are pretty much the same.

What are you trying to measure? I suggest you remove some of the extra traces. Tap the boxes n the left hand side labeled Tr1, Tr2, Tr3, Tr4. One tap will turn the selected trace off, the next tap will turn it back on.

Sometimes this site runs a little behind in its syncing to the Federal register.

@gortex2I think it is, just having trouble finding it.

@SshannonThere is a post I can't seem to find anymore that I wanted to link here. A guy had a nice RT97 build running off solar up in the hills/mountains. Does that ring any bells?

Retevis has a turnkey solution for you. Their RT97 repeater is about $300-$500 depending on accessories. With most things vhf/uhf height is more important than watts. If you can get the repeater (or its antenna) at about 50' above ground, you should be able to cover a few neighbor hoods. Here are a few threads in this forum on the unit. https://forums.mygmrs.com/topic/4843-retevis-rt97-gmrs-repeater/#comment-47459 https://forums.mygmrs.com/topic/3755-rt97-real-world-output-power/ https://forums.mygmrs.com/topic/3353-retevis-rt-97-battery-size-recommendation/ https://forums.mygmrs.com/topic/2744-retivis-rt97-portable-repeater/

The GMRS-9R and UV9G along with the UV5G are GMRS "legal".

What antenna is that?

The NanoVNA is good for the money, about $60. There is tons of documentation and easy startup guides on youtube. Lots of guys here have one and can attest to its value.

If you have an antenna analyzer or NanoVNA you can 'sweep' the antennas and see where they are resonant. Some antennas may have a stamped or printed mark near the base with a part number or frequency range.

The CPS is useable, but a little clunky. I'm looking forward to CHIRP adding the radio.

I’d go ahead and ask, explain that you are new and trying to get things figured out.

Make sure the radios are far enough apart so they won’t desense each other.

Could you make a post about your box build?

make sure you have the correct drivers for the cable

It seemed to be a Public service piece to change the image of "prepping" and get more people thinking that its not for loonies expecting the zombie hordes

You can play around with the Radio Mobile Online website to see the local affect of increasing antenna height, antenna gain and radio watts.

AS BAD A BAOFENG!

There is something to tropospheric ducting on UHF ( at least that's what the local old timers say). Some days before storms, I've been able to talk to repeaters 75-100 miles away on my rubberducky antenna and HT. Before I got my antenna up high, there were repeaters I couldn't get into except in the late evening and very early morning. I am in a relatively flat are out near East TX.

I made one (see "Rate my Yagi" post). Using my 5W HT with the antenna height being about 7', I was able to get into some repeaters about 40 miles away. Standing on my roof (antenna height 31'), I was able to do 75 miles. I imagine a better made yagi would do even better.
