Yes, Yes and Yes. Listen for Red 1 or another number for Airport fire on the Calgary Digital system. I do not know the station number of the airport fire station [? 13] but I'm sure it is listed somewhere on this thread. With an HP your should be able to hear all the ones you have questioned. I can even inside buildings with the stock antenna. I have also heard Cochrane Fire on the frequencies posted in the Database. I have heard Chestermere/Langdon Fire on the UHF frequencies listed in the Database. As always, check with what is programmed in your HP, or Favorites, etc.. There is activity on all these almost on a daily basis. You can hear Airport fire whenever there is a plane landing at YYC with some problem. This can be heard on the Airport frequencies as well. Off the top of my head, I am not sure if that frequency is one of the airport apron frequencies but the Airport Controllers will sometimes tell the pilot what frequency they can talk to Red on. I believe it is usually in the 123-125 frequency. It can be interesting to hear how Air Traffic Controllers handle a declared emergency or a non emergency aircraft situation. And when Red is called out, usually other stations are, as well as AHS EMS so can hear them attending as well. STARS is often placed on stand by as especially when a larger aircraft is involved.
