Fine bud, I won’t help anyone else that asks for it here. Y’all are toxic.

Here’s an example,
You have a 6 meter yagi, 2m yagi and a 70cm yagi stacked on a mast. The 70cm yagi should be 1/2 wave @ 70cm from the 2m yagi. The 2m yagi should be 1/2 wave @ 2m from the 6m yagi. The lower band yagis will not “see” the higher bands. Same goes with mobile antennas. 70cm whip should be 1/2 wave @ 70cm from a 2m whip etc.
Dual band whips are using the lowest operating band.

Reflectors are physically longer than the driven element.

The highest band used designates the minimum distance. Ever stack yagis? This is what is done. The lower band antennas do not have adverse effects with higher band antennas.

Double Waiting = Dual Watch
I ran into that with the UV-21R.
Dual Power Tube = 2 Battery cells.
That page is a difficult read. Reminds me of 1985 VCR timer instructions.

Regarding pinch points, I have found that taping two short cut pieces of coax on each side. They will take the brunt of a pinch instead of your active coax. Metal ducting tape works well to keep it in place. Add some slack where the bends are so the bend diameter is larger. I think the articulating lip mount will be your best option.
Some helpful images for mobile antenna mounting considerations.
Good luck on your install and happy mobiling!

I am biased for C4FM (YSF specifically) as well. Especially the error correction in digital narrow mode. I used to run a simplex net on 2 meters. I’d have stations beacon in GM mode to get checked in early. GM mode beacons your call every 15 seconds and displays calls received. It worked really well. GMRS could use something like that since it’s UHF only.
Thanks for the reply.

I work for a Motorola service shop. So I work with TRBO/DMR a TON.
I will say this.
How would DMR work on GMRS for simplex only? Would C4FM be a better option? Just program call sign and select digital modes DN or VW and no networks, databases or talk groups needed. C4FM would not allow two time slots though.

The one thing I will NOT do is drill any holes for a NMO mount.
Well you’re no fun, lol.
I would look at a fender mount or an articulating lip mount for the rear hatch/trunk.
Good luck with your install!

I would support digital voice on every GMRS channel for simplex use as it extends range and readability but not for repeaters. FCC should limit which digital voice modes could be used such as C4FM/FDMA. Using DMR/TDMA would be so confusing to GMRS users. This is just wishful thinking. I mean look how long it took for CB to get FM approved.
Fun topic though.

CN-901V to be specific as there are several 901 models. The V goes to 525 MHz.

The Diawa CN-901 has been my go to meter for vhf/uhf.

[mention=13532]WRYU400[/mention] I had written off the UV-17R because I heard that the display is hard to read in direct sunlight but now you've got me thinking about it again.
I cannot speak on the 17s display. The 21Rs display is difficult to see in direct sunlight when the backlight is on. When the backlight turns off (not scanning) it’s pretty easy to see.
Some of the stock photos are misleading because it will show a white text on black background but in actuality it’s a black text on white background. I hope this helps.

Actually, it's the ARRL that has a Field Day. It's the last full weekend in June. Next year it's June 29 and 30.
Let’s not forget Winter Field Day!

I’m a big fan of the Yaesu FTM-200dr but I am a fusion repeater owner so I have to have digital. I also have the 100, 400 and FT-70. All of which have excellent receivers.
The 200 stands out because of the PMG feature which allows 5 frequencies to be monitored simultaneously with signal levels. Currently I have my repeater, my hotspot (uhf simplex), local repeater, 146.520 and GMRS 19 in the PMG list.
I know it’s way more expensive than the FTM-6000 but it’s a much better radio and it has GPS and APRS.
Good luck and 73.

I was going to get a couple of these UV-17Rs for glovebox radios. I liked the flashlight on the bottom and some reviews said the receiver was very good. I bought the UV-21R instead because of USB-C charging and it came with two antennas. I couldn’t wait to get it on the bench and test the receiver sensitivity.
Well, it came in and had a bad display so I got returned. I bought the two pack and those both worked. A buddy bought two also and wanted me to program them so I had four units to test.
Let’s just say I had to retest all of my HT’s because the receiver was extremely sensitive.
The only other HT that beat it is my Yaesu FT-70 and just barely. -127 vs -128 dBm.
Now another buddy bought one and says his will TX on 222 MHz, mine will not. 136-174 + 400-520.
Very impressive for a Baofeng/Abbree.

...Thats why they're called Sad Hams.. Killing their own hobby, one potential new member at a time...
50k active GMRS licenses
758k active amateur licenses
The amateur hobby is not dead nor killing members off.
Funny how non-hams complain about ham radio operators.
Thank you for the entertainment

Gamers have taken interest into RadioSport (contesting) and are doing well. They get extra class licenses and really have a great time.
I think those young ones that have the desire for radio will eventually find their way to amateur radio. No reason to try and coerce them with prizes.

I doubt that anything would happen. Unless you were aggressively kerchunking an active repeater, nobody would hear you. Chances are that you are using a handyscratchy on simplex frequencies. If by chance someone did hear you, they would give their call sign and ask if someone needed help with their rig. The amateur community is very helpful with new operators for the most part.

Should not use LMRxxx on a duplex system. It’s fine for a simplex system. 1/2” heliax is a start, 7/8 would be more appropriate.

You will hear a courtesy tone, squelch tail and then the repeater should identify (in Morse code).
Sometimes you will hear the repeater owner tell you to identify and stop kerchunking their repeater.
