I was told by a "Live audio admin" that GMRS (General Mobile Radio Service) was not allowed to be streamed on Radio Reference, and yet this feed was allowed?
Heartland REACT (462.700) Live Scanner Audio Feed
Like Kendirk said, general GMRS/FRS/MURS feeds are not approved as they would have little interest. We also do not approve CB feeds. All are in the "children band" class as far as feeds go.
REACT is OK as that is in the same class as an ARES, SKYWARN type feed.
In this case, this REACT feed (official description is Heartland REACT (462.700), is an "Official Feed". Meaning Lindsay approved their status. Used by Heartland REACT storm spotters during severe weather and to coordinate public events such as parades, walks, bike rides, Halloween, etc.
While ARES groups go this, a lot of general Amateur radio groups do as well.
