Current HSV Freqs
Sorry I'm so late replying, haven't been on RR for awhile.
You will need a digital trunking scanner to listen to HSV radio traffic. HSV is a Phase I system so there are plenty of affordable scanners around that can receive it. I use a Shack Pro 651 with good results. Since this is a multicast system, your scanner may hear more than one tower.
These are the 4 control channels for HSV Public Safety System. This is all you need to enter in the frequency table in your scanner. Configure the system type as APCO 25 Auto.

This is the latest known talkgroups for HSV radio system. Don't waste time on encrypted groups, you won't hear them. If there is not a description tag on a talkgroup, or it is listed as unknown, it is likely encrypted. Once you have put the Alpha Tags on the talkgroups in your scanner, lock out the wildcard talkgroup to filter the encrypted traffic, as it will just sound like noise.
