I would close them.
On topic:
- How does a repeater work?
- What are the essential components of a repeater?
- How can I estimate the power and antenna requirements to cover an area?
That's not what's being asked in these questions. They are much closer to product recommendation questions. One of the questions blatantly asks:
Can I use our existing Kenwood TK-863G-1 to accomplish the scenario above [use it as a repeater]. If not, can you suggest some cheap alternatives?
The other question is probably looking for product recommendations:
I am a noob to a lot of amateur radio and I am investigating and planning a repeater setup to be installed in my workplace.
[...]
I wanted to see what suggestions the community has for a cost effective repeater setup for a scenario where we would be repeating 3-5 channels of uhf traffic. [...] A functionality that we would like to have is to also repeat the NOAA weather channel for our area to a uhf channel for our handhelds to tune into.
You have the requirements:
- must be cheap
- must repeat 3-5 channels of commercial UHF traffic
- must be approachable for a "noob"
- must repeat NOAA weather
The question wanders a bit, but probably it's looking for a product recommendation.
I think this is pretty well explained in the help center. https://ham.stackexchange.com/help/on-topic says:
There are many applications of radio that are not Amateur radio. For example, GMRS, CB, PMR, and all manner of commercial applications.
It also says:
Questions may not be asked here about: [...] shopping recommendations for specific products
The problem here seems to be this user doesn't know what amateur means, either in English generally, or specifically in amateur radio. I quote with added emphasis:
I am a noob to a lot of amateur radio and I am investigating and planning a repeater setup to be installed in my workplace.
Evidently this user believes workplace activities are somehow "amateur", which means "engaging or engaged in without payment; nonprofessional."
I don't think there's anything we need to do to make things more clear. There will always be people who misunderstand words. Close the questions and call it a day.
