I asked ChatGPT 4.0 what LMR meant as applied to coaxial cable. It gave me an excellent response, including that LMR is a trademark of Times Microwave Systems.

I rarely use search engines anymore. I'll bet the same is true for many people.

Bard also gives an excellent response.

In fact when I used regular Google, the results are good enough for me to deduce that on my own.

So I consider GP's search skills inadequate. I mean it's not exactly wrong to desire a tool that handholds you and feeds you the answer; but if you are willing to do a little bit of deduction Google is fine.

Regular Google itself tells you that. At least for me, when I tried this search right now, the first snippet says "These letters indicate the brand. LMR is a trademark of Times Microwave, whereas RFC is made by Shireen." It's the second snippet that says the last minute resistance thing, and it appears to be from someone's personal blog that blocks IPs from the United States, so without logging into a VPN, I can't open the site to figure out why it thinks this.

I would assume the best actual source is the USPTO trademark registration database, which has this entry: https://tmsearch.uspto.gov/bin/showfield?f=doc&state=4805:pw...

It appears to indeed mean nothing, but of course, it took me a whole two minutes or so to find an actually authoritative source. Everyone knows no real user will ever do that and just wants a search engine or chatbot to dictate reality to them.

I tend to ask ChatGPT first these days, but then follow up with a DDG search because I don't fully trust ChatGPT.
Phind.com uses the same engine but provides sources.
So does Bing, but somehow giving it network access made it worse than ChatGPT at everything.
