I use programming software (ARC XT) to set up my Uniden BCT15X. I have set up 4 different sites to scan, one is Snohomish County SERS and the other is a King Co site. The King Co site I chose is Seattle Simulcast. Through the ARC XT I was able to pick out just a couple of cities in King Co that I wanted to listen to. For some reason or another I have not heard anything from the King Co site. My other 2 sites in Snohomish Co and WSP seems to be working fine. Any suggestions or ideas?
