Posted August 12, 2013 I have recently started to occasionally listen into SFPD radio, as its one of the clearest around and easy to listen to. I do struggle with the unit and patrol radio callsigns however. I have heard Adam14adam and 14boy and so on. Are the units callsigns numerical to indicate which station they are out of and which unit they are out of that station? I assume each unit goes on duty and is assigned an area within the stations district to patrol. I have not K9 callsign yet. And lastly does SFPD operate double crew units or single crew units? Once again many thanks for any info. Share this post Link to post Share on other sites
