The PSR500 works good. I like the OOUI and no TG limits. I use the Multi-Site Trunking Mode. And on a good night, I can hear Sussex Co with the RadioShack 800 MHz antenna from Middletown.
I programmed the entire State by hand. I was pleased when DonS and Mike released some software to use. Now I get to listen instead of programming.
Cannot recall, but I believe that you also have a 396 or 996 - correct? If so, I'm very curious how the 500 compares in sound quality on the DE system.
