I tried post about this in the Uniden specific forum but can't due to "insufficient privileges"! I heard that that Proscan software is pretty good for Uniden scanners from a ham guy I know. I already have the Sentinel and ARC536PRO software for my Uniden SDS200 scanner, But when I tried to install the software, my WebRoot anti-virus says the DDL file is a trojan horse!! Likely a false positive but anyone know for sure? Anyone out there use this software? Do you like it if you have it?
