I have not noticed it much lately, but I have had trouble in the past when listening to a station that was not local. I usually listened to a 12kw station that is no more than a mile from me when in the city, so the RF is strong, but a similar station 20 miles away...yep, same experience.
On my scanner, or if I kick my VHF off PL when in my work truck....yeah, I get tons of noise when at any of the newer upgraded-signal intersections in our city. There have been tons of upgrades in the past year, so now on VHF I hear controller noise, and the VHF SCADA doesn't help either.
There is an automotive plant I go by everyday, their intersection is getting a huge upgrade, but I probably won't notice any worse issues there, because the plant has 5 VHF repeaters, a paging TX and they are busy...so there is enough intermod to scramble your thoughts! Not sure why this plant continues to use 50 watt VHF repeaters for all functions of a 100 acre campus....(10 watts would work...the portables are only 5!) and why they are not on a UHF trunk, which would work much better. I was told that when they opened in 1974 with like 25 employees, that they had about 10 VHF radios on 154.570...and so as they expanded, and so the did the communications need, they added radios and frequencies and just stayed on VHF because MARFAC (Coordinator) had freqs to issue. So for the love of a Ritron on 154.570...there is a mess today. LOL. I would love to see a TRBO system go in there, it would work well.
