The Daj at the end of my name comes from my Mother's maiden name, Dajnowski.

The attached paper was published in an engineering journal. It goes a bit more into the details of narrow verses wide band FM. The material isn't for the "casual" reader. Narrowband vs Wideband.pdf

Hey folks, a few months back, I discussed providing a presentation on the introduction to GMRS, to just cover the basics. We held the presentation a couple of weeks ago and I wanted to share the video with everyone. Fair warning, I'm not a pro YouTuber and my collar mic dropped with a few minutes left... please be gentle. LoL This is geared towards people with little to no experience. Hopefully it helps some people. The PowerPoint presentation is available for download, here... https://marcspaz.com/gmrs/GMRS101.ppsx Thank you to those who helped with content ideas.

There are multiple sources for connectors besides the big A and Flea-Bay. Look for ham stores for ready-made cable assemblies and adapters along with various component suppliers such as Mouser and Amp.

I know it’s technically a ham radio, but am wondering if anyone has any experience with it.. is it better quality than the BF-H8/BF-9G? I have tried both of those and they seem to have some weird behaviors like being unable to tone scan.. and intermittently crappy reception that magically improves if you press the menu button. The intention would be to use it for GMRS primarily.. I can’t justify spending $150+ on an wouxon HT when I can get their compact 20w mobile product for like $190 (likely my next purchase) and prefer the more feature rich models.

Those SWR and power reading look good. The popping and scratching can definitely be from the power lines, especially if they are high power transmission lines. Or it could be obstructions between you and the repeater too. I would still double check all coax connectors just to make sure.

Also, you mentioned usb-c, you can get batteries for the UV-82 that are usb-c and larger capacity of 2800 miliamp hours. I have 2 on order from Amazon that'll be here Saturday. http://www.amazon.com/gp/aw/d/B0C3669GMD?ref=ppx_pt2_mob_b_prod_image

Your best bet is to drop a NMO mount center of the roof. One hole. Throw a UHF 1/4 wave on it and enjoy scanning your DPS stuff and use it for GMRS. Simple effective and cheap.

A standard mic will work but it will only transmit on one channel. (A, I think.) The dual-PTT mics that I found had poor reviews.

When installing an NMO you want the outside ring the same height or a bit lower than the center. On a standard mount thats how it should be. With a 3/8" style mount you want the center slightly above the brass ring.

Hmmm - that’s a valid point. I forgot the btech was based off the UV-82. I’ll look into UV-82. appreciate the tip!

You may already know this but here goes: A cheap SDR will give you the ability to see what's out there on HF, VHF, UHF, slow scan TV, track satellites, listen to the space station etc. Additionally, you can listen to international shortwave broadcasts, pirate and spy stations. Listening to active NETS is super easy. -There is a lot more but it's TLDR. You can program in all of the active frequencies within your antennas reach and use a scanner plug-in to monitor traffic. People get into the radio hobby for different reasons. I personally like to listen mostly. I humbly advise that if you want to be a HAM, check the radio bands chart and then use the cheap SDR to monitor the allowed bands that you are shooting for. This will give you a realistic idea of what is going on out there and help you decide if you would like to spend time and $$ to get in on it.

Thanks for the replies. Here in Arizona DPS is still using 460MHz and I scan the 4 local channels on my HTs all the time. I don't have to put the radio in the stock location, just thought it might be easier that way but my cup holder is messed up so I can't retract it so I have a big hole to mount a radio if I needed too. As far as antennas, as long as I didn't have to make too many holes I could make a second location for it if I had to. I'm just trying to keep things simple. CHIRP compatibility would be a big plus and I'm not opposed to a radio I could "unlock"(like with the UV-5R's)in order to get GMRS and even MURS with scan only for 460MHz. I've found a few radios on Amazon, need to research them a bit more but wanted to get y'alls input too.

After the system I was involved with during the narrowband changeover, we did not have any issues as most have described with their experiences. All of our systems were designed with overlapping coverage for redundancy with simulcast, and voting receivers. There could have been some propagation differences but it didn't impact operations. Even the difference in the audio quality was negligible. I guess when you use quality radios you don't experience those issues.

Fixed it for you: 亲爱的宝峰： 我看到不久前你们推出了新的GMRS HT（UV-5G Plus）。它看起来是一个相当不错的升级，但我认为您再次错过了将一个非常好的收音机变成一个非常好的收音机的机会。我的抱怨完全在于菜单系统。 1. 为什么我们无法在菜单系统中更改/输入频道名称？ 2. 为什么菜单系统中不能设置某个频道是否可以扫描？ 宝峰，我认为如果你解决了这两件事，你的收音机的价值/质量矩阵就会上升一个档次。 我真的很想买这台收音机来添加到我的收藏中，但我不想让自己感到沮丧。 感谢您的聆听。 WRPL700

141.3 traditionally was the REACT tone which kinda became the travel tone. Sent from my SM-S901U using Tapatalk

It appears that 99.9% of the GMRS repeaters throughout the country operate on wideband channels. The only exception to the norm is the Arizona GMRS Repeater Club which operates all four of their repeaters, and nine tactical channels on narrowband channels and without any issues in regards to audio quality. Personally, I would like to see the FCC mandate that the GMRS channel operate on narrowband channels. If it works for Part 90 radio services it can work for Part 95 radio services. Narrowband emissions help facilitate spectrum efficiency and minimize adjacent channel interference.

I have had/used every brand of GMRS radio in my Jeep(s) and almost every model of every brand, and for Part 95 "GMRS" radios, I prefer the Wouxun KG1000G. It is a better quality radio than BTech and most (maybe all) the other brands, it outputs a full 50W, and has a remote-mount removable faceplate. Several of my off-road friends use this radio and they are all happy with it. And FYI - even though its spelled Wooks-On, it's pronounced "Ocean" .
