Hi all
I've been slowly adding updates to the statewide Arizona Public Service Corporation trunking system. If you don't know normally listen to trunking, you may not have noticed that some elements that you might expect to hear on other frequencies, are actually hidden here.
For example, did you know that the Arizona Division of Emergency Management has 3 talk groups on this statewide system? It is one of their redundant radio systems that they test and would use in case of a state emergency.
Here's my frequency challenge for you. It will cost you as little as 5 minutes of listening to help out. If you spend more time monitoring, then that will increase your assistance to this challenge.
There are a couple of goals:
1) ID which frequency has a control channel on it in your neighborhood.
- - You will use the frequencies that will be provided below. If you've never listened to a Motorola trunked system before, one of the channels will have a continuos machine type sound on the frequency. It only goes away, if it changes to one of the other frequencies associated with the trunked system. It does not sound like static, but an actual "running machine" type sound.
2) ID the system site number of the control channel frequency that you are listening to on your radio.
- - In order to do this, you will need to have a scanner or radio that has been tapped so that the computer will interpret the control channel data for you. I highly recommend the Unitrunker software as it requires little work on your part, does not require any anything but a cable from the discriminator tap into the sound card of the computer. NO other hardware required
3) ID the talkgroups that you hear on your local system.
- - This will require that you have trunk-tracking scanner. This may require dedicated listening, that is exclusive to the local system. This will help to ID talkgroups that may be heard statewide. If you are in the southern part of the state, you will want to be sure that you've set your scanner to monitor the system as a "Splinter" system.
I'll be happy to be the "goto" person on this. I am getting very familiar with 4 different tower locations.
Please help contribute to this challenge. Even if you only want to help under goal number 1, it will help us to correct/update the data on this system.
- Please report which frequency that you are hearing.
- Please report which tower location you think you are hearing, if you are not using Unitrunker or some type of computer software which ID's the transmitting towers "site number".
- If you can ID the tower location, please state that it is a positive ID.
- Please report any associated frequencies that you notice with this control channel, whether it be via your scanner or a trunk tracking computer software.
- Only report the frequencies associated to the same control channel.
- Please report any Talk Groups that you run across on each site. Even if you can't ID who was on the Talk Group, this will help in determining on which sites these Talk Groups will be heard.
I will then assimilate all of your wonderful input and get this over to the system admin for inclusion into the APS Trunk System.
The frequencies will be in a follow-on post right after this one..
Thanks for your help.
