Hey guys, I'm in Houston for a couple of days and trying to listen to Houston Fire/EMS. I have my PRO 668 with me and thought that I had it programmed correctly; however, I'm not hearing much. I have my conventional scanner set to the uhf station alerting frequency (460.575) and hear that fine, but my PRO 668 when set to the same channel on the TxWARN system only catches the transmission about 10% of the time. Any ideas on what I'm doing wrong? I'm listening from Northwest Houston.
