I have been using them in my cars with Walmart EverStart MAXX batteries and so far no corrosion. They come with a tiny spray can of some anti corrosive liquid. Can't say if it works or I have been lucky.

Robotic sounds, extreme audio level changes and muffled words are tiring as well.

The audio quality of these various vocoders is really not as good as "wide" +/- 5.0 KHz FM analog when in strong signal contour. These studies seem to focus on the fringe where the digital has an advantage.

I would still be using XP at home if it were not for the browser security issues. Win 10 has proven to be a huge annoying learning curve for me, as the office suite, Word, Excel, etc, Acrobat and associated programs are very counterintuitive compared to old versions I got to be a power user on...

My only comment is that VHF repeater systems have some design challenges versus UHF. 1) Getting duplex pairs can be a nightmare. 2) The noise level at VHF can be very high both at repeater sites and inside buildings. 3) VHF portable antenna efficiency is awful. You may want to explore why VHF is...

I could never understand Motorola's rush to embrace Windows for dispatch operations. The console, 911 and and communications do not need to be wading in that quagmire just "for convenience".

What mmckenna said. The equipment belongs to, is controlled by, someone else. No independent way to verify physical security to "cloud". Its the cloud and subject to failing circuits outside the realm of the customer. Cloud Clowns promise "best effort". I got that from a carpenter recently...

Motorola was pushing CORE on a cloud subscription service a while back. I dont know if that got traction, but I was very leery of that proposal.

It only gets weirder: Alabama contractor’s tower crews to share in an expected $120 million windfall from an unexpected fine art find

Here in the US those radios remain useful for Ham radio, though the ability to use them on police and fire frequencies is frowned upon. They are sold openly on Amazon with default programming that offends every radio service. Decades ago one could buy a "saturday night special" which was a...

Take the antenna off or put a small piece of wire in its place and drive around until you hear it again.

Do you have any industrial plants that operate those strict hours?

I could not find any. The radio must have the certification number affixed to it. If the seller cannot provide a picture of such certification number, it likely does not exist. This is a growing problem in the US as sellers are importing radios that are not certified or are counterfeit replicas...

So true, I hear a grown man crying on TV about money.

I don't really know except I am certain they have to check a box somewhere. 99% of folks looking at an FCC grant would not know what it means.

Those type acceptance grants are generally Part 15 or some nonsense Part 9 , just enough to fool Customs.

If ever a standard was required, that was the one. More junk I cannot throw out.

I have a zillion USB to xyz connector cables and hesitate to throw any one of them away.

Some background on GMRS channels and why the FCC permitting part 90 users to license inside the guard band of GMRS is a bad thing. § 95.1763 GMRS channels. (a) 462 MHz main channels. Only mobile, handheld portable, repeater, base and fixed stations may transmit on these 8 channels. The channel...

Can you provide information about the receivers that you are hearing this signal on.?
