Well, people were whining to release it...so they did. Firmware isn't ironed out yet. Expect a lot more updates. Sent from my SM-A102U using Tapatalk

Look at how little filtering the RT-22 has. There's all sorts of unpopulated pads on the production model that aren't on the FCC submitted model. I bet those harmonics aren't 50dB down on production models. Again, you're in a highly unconventional RF environment, RF power coming from the Candelabra transmitters through a typical UHF passband (370-530 MHz) should be in the ballpark of 0dBm. Most people are around -50dBm. That's a HUGE difference. That said, CCRs aren't meant to be used on fixed antennas; they're designed to be used as portable radios. Most handhelds will show measurable desense on a high-gain base antenna, CCR or not. The typical CCR construction with a wide-open frontend happens to have a lot more desense. In open spaces away from other transmitters, they have a slight advantage due to less filtering loss. They have their place, and that's on-site business use on the hip; can't desense if the strongest transmitter is the repeater you're using. They also work good enough for amateur use that people keep buying them. Few people in reality will cite receive performance as a reason to upgrade from a D878UV or something to a Motorola or Kenwood, it's mostly for audio quality. Over here, where the noise floor is high on VHF, I get better coverage on GMRS than MURS, and better 800 MHz Part 90 reception than 460 MHz Part 90 reception. In my experiences with line-of-sight conditions, the higher gain from UHF antennas gives better audio (helps to make up for deep fades, which are briefer on UHF), while in mobile-to-mobile situations with some separation VHF has an advantage in punching through terrain. UHF has much better spot coverage. For mobile-to-mobile operation, ~50W out into a gain antenna on GMRS should give universally better coverage than your Part 95 compliant MURS setup. Portable-to-portable simplex will be much more variable due to terrain. Noise floor is also an important consideration in urban environments, and lower frequencies will have more noise than higher frequencies.

Well, I can't say I agree on your first point (see below), but, I do agree whole-heartedly with your conclusion. Agreed. In open space, VHF will travel further, have lower path loss and better building penetration than UHF (See this paper for more information). On the other hand, UHF may actually work better inside a building because of signal splatter and reflection.

I’m in the market for another MXT275 in the next several months. Glad I can support the forum while I’m at it.

Kenwood has it's own quick connect on the radio, however many of us in GMRS, and almost everyone in ham is using the 15/30/45 Powerpole connectors from Anderson. https://en.wikipedia.org/wiki/Anderson_Powerpole

Yes.

The problem I see with some of the Zello channels, be it "radio" related or not is owner/admins that spend way more time on air barking at people, asking who is xxx and who "trusted" them in. I can't even log in to Zello on my PC without 3 seconds later some admin yelling my handle wanting to know what I am doing on the channel. Well...you "trusted" me in....that's why I'm here. I really laugh at the ones that are setup as "anyone can listen" but they still get all bent when you appear online. I don't spend 10 hours a day on Zello, so no, you probably haven't talked to me. When I log on to see what's being discussed, stop acting like I'm an intruder. You let me in. In one case you emailed me a password. Today some dude went in a level 13 panic calling people trying to find out who I was and who let me on....I never had a chance to answer, so I just let him go on sounding like he thinks he is so important, if he wants to play radio cop...have fun spazing out! There is nothing that ruins human interaction, like.....human interaction!
