It seems I can upload Calgary ems frequencies but hear nothing on playback. no problem uploading Calgary police service and fire. does it have anything to do with Calgary digital radio system now being called Calgary municipal radio system.

ems gone silent
I'm not sure what that means. Ive checked afrrcs and don't see any ems frequencies. I'm not sure what I'm doing wrong

Thank you very much for your help. I wonder if the same thing will eventually happen to CPS & fire
Thanks again for your help
Surely we will be able to break this ems encryption at some point. I know win500 doesnt work for this now

You need a AFRRCS radio with EMS talk groups and the encryption key in order to hear them.
Ok, here's the thing about encryption, to put this to bed once and for all:
Encryption is designed specifically for the purpose of preventing you from hearing something you're not supposed to be hearing.
As such, there are laws in place to make it punishable to "break" encryption.
This can't really be compared to getting a new digital mode enabled in a scanner, because the digital modes aren't intended to keep you from hearing things. (That may be a "side benefit" for some closed-minded agencies, but it's certainly not the primary purpose of a digital mode.)
Saying that you wish someone would break encryption is like saying you wish that somebody would give you a key to unlock a warehouse full of stuff. You might get access to the warehouse very briefly, but you'll get in trouble for it, and all the owners are going to do is change the locks. The same thing would happen with an encrypted transmission if the encryption key ever got released or "broken": The system managers would change to a completely new key in a matter of seconds.
Like it or not, for wise or dumb reasons/excuses, some agencies have enabled encryption on their channels, and it's doubtful it will go away, ever.
Can we please make this the last time we discuss encryption in this thread? RR has rules that encryption is to be discussed only in one thread on the forum: this one.

To expand on this, if a key is compromised, AFRRCS users have the capability to rekey(Over The Air Rekey, aka OTAR) the radios over the network. As in, the key manager can remotely rekey any/all radio when ever they wish.
My appologies. I'm not very knowledgeable at this stuff. thank you for your help
Not a problem. I didn't mean to come off like an ***, and sorry if I did. It's just that encryption is a dead horse that has been beaten so hard on this website that it is just a pile of glue now. 
Personally, I don't agree with the amount of encryption that is being employed in agencies all over this continent. I dispute the argument that general operational channels must be encrypted for personnel safety (despite the conversation I just partook in in the encryption containment thread mentioned above). I am the communications officer for a local public safety agency which prides itself in its relations with the community at large, and you can't maintain that kind of relationship if you are hiding yourself from the community. Not only do we not encrypt our comms, but we stream them on Broadcastify, in an official capacity. We're happy to have people know what we're doing. During a particularly intense incident several years ago, we had friends, family, and general public in Newfoundland, Ontario, and several US states contacting us in near real-time to compliment our incident commander on her and her crews' performance.
Things that we don't want everyone on the planet to be learning about is simply not broadcast on a radio frequency. If we had a reason to regularly transmit private/privileged data and could not do it without using a radio, I would see a benefit for having some encryption - maybe one channel. But definitely not all of it.
I can't speak to AHSEMS's decisions or rational because my (other) job involves doing dispatch for them, and for me to offer comments could be seen as a violation of certain employment policies. But as a public safety person in general, I can admit the benefit to having encryption in some but not all situations in this modern day.

Thank you Jay. I just dont know the terminology. I only know that i connect my scanner to win500 and I get to hear stuff. I wont post anything else on here. I think the more i use rr ill understand the rules and where to talk.
Don't do that, the forums exist so we can exchange ideas and opinions. I only moved the posts to keep the AFRRCS in focus, no need to feel that anything wrong was done.
It was a legitimate question to ask where some of your favourite monitoring has gone to. I would want to know the same as well.
See you on the forums!

jloriginal,
See:
How safe is safe? AES 256 encryption and your data. - Canadian Cloud Backup | Datacentres in Canada
It gives a good plain language overview of what someone would be up against if they tried to break the encryption key. Advanced Encryption Standard 256 bit (AES 256) is the system used by EMS and others such as commercial vehicle enforcement on AFRRCS. Just a matter of time until the RCMP is on board as well.
Don't shy away from participating in the forums, in my experience they're a friendly bunch and a wealth of information.
For what its worth, I agree completely with Jay's views on the amount of encryption.
