brought my gre psr 800 to the city, north up by franklin mills mall there is not simulcast distortion. center city there is simulcast distortion but not as bad as some places. put the stock antenna inside a hole in the side of an empty paint can near the bottom and its much clearer. ....this is the 2nd time i have brought this radio to the city and i have never heard any of the detectives talkgroups key up at all, radios with encryption is an extra $2,000 right? and they are not using them, probably push to talk cell phones instead. give them to me instead if they are not going to use them
