What could this possibly be 890.400 - 890.600 mhz

These big blocks of this very distorted high pitched sound which I have seen across 600-890 mhz freaks me out in a way, and I have no clue as to what it is. My only possible guess is the tower behind my backyard, which is some internet or cell tower.

cellular is also in the 600-700 band along with digital public safety systems in the US

Wouldn't "big blocks" as described by the OP indicate cellular? Unless I'm mistaken, they are very wide bandwith signals.
Indeed. Also I've yet to see 600 MHz public safety systems, but boy wouldn't that be fun!

With any tower used for radio or cellular being that close, your radio might be overloading.

i did not mean to imply they were in the 600, should have spelled it out and said certain parts of 700 have public safety. but yes if they use commercial LTE systems there is a good chance at least some of their traffic goes out on 600 depending on a particular carrier's setup. i don't think many US public safety use commercial LTE yet, but i really do not know on that.

The only 600MHz band 71/N71 in the USA is T-Mobile. All 84MHz of it.
absolutely incorrect, the carrier i work for is NOT TMO and we have b71/n71 on a majority of our sites. TMO does have the biggest coverage in that band, but not exclusive. and actually they are on several sites where we are and both of us run it.

UScellular's wireless division has just been acquired by T Mobile last month so he's correct.
