My guess is that the radios were initially added to the list as an alias (use vendor model). Later, a developer added direct support for the radio in the CHIRP UI. Either the developer was unaware or forgot that the alias entries needed to be removed. I'm usually guilty of the latter.

I think it's almost this, but slightly more complicated. The RH5R is a cloen of the UV-5R in the code, but is also in model_alias_map, hence the duplication on the page. It should be removed from the map as a result.

The V2 version has a separate implementation (which hasn't been py3-ified btw) and appears to not be a clone of the UV-5R as indicated. Thus it too should be removed from model_alias_map.

I push queued a change to do that, thanks!
