For the last 6 months at least I have been having problems receiving the New Jersey State Police 860 MHz multicast system. So I finally decided to try something. I set my HP-2 up and monitored the system with the indoor antenna that came with the scanner. The HP-2 had no problems receiving the system.
So today I took off work early to take care of my "puppy" and decided to play with the 536 HP with an telescoping antenna on the back of the scanner. Well it worked great. So I went in an turned on the attenuator for the system and I was now receiving the system with the telescoping antenna, a 800 MHz antenna inside my window just above the scanners and an identical antenna on my tower at 30'.
All is good. I had noticed that the 536HP was prone to brute force overload more than the older Uniden scanner I had used to monitor the system way back when I bought the scanner, 2 weeks after it was released. That's why I was using the antenna mounted inside my radio room in the window. It worked fine untill about 6 months ago then it went down hill after that.
I am attributing the problem to a cell phone site less than 1/8 of a mile from my house. the indoor antenna shielded the indoor antenna from the site. BUT there is another site about the same distance from my house but not being in the shadow of the house so I guess there must have been changes to this second site around 6 months ago.
I found when I purchased my first 536HP that when I turned on the attenuator on another system but operating on 760 MHz it solved a problem receiving this simulcast system.
Just thought I woulod pass this info on just in case it might help someone else having the same problem
