Shelby County TRS
Shelby County TRS Frequency Update.
Active Control Channel frequency found.
Frequency: 152.720, No FCC License found.
152.720 appears to be an unlicensed Control Channel frequency for the Shelby county TRS.
I believe this frequency was originally listed & decoded as site 505 but it appears to have changed\
System Id & Tower Site Id recently.
Possible New Shelby County TRS System Id is 00A, Site NAC is 00A, Tower Site Id is R-010, S-010, WACN is 92778.
This appears to be a Harris VHF trunked system.
Control Channel is broadcasting Multi-Packet/Multi-Block or Extended Packet info.
Signal received on I-459 at Exit 17, West to Exit 104 near McCalla. Date 04-23/24-2015.
Signal Strength was at 95 to 99%.
Tower Site appears to be the Chelsea, AL Tower Site?
Did not hear any activity from any voice frequencies, clear or encrypted and did not hear any other
control channels broadcasting from I-459 or I-59/20.
Using a Pro106 the Tower Site did not appear to be trunking, unless it was broadcasting in Phase 2.
Any other users in the Shelby County or Jefferson County area may want to scan the VHF band and see if
any other Towers are broadcasting and post any info found.
FYI: The Mobile County AFRN 700 MHz Sites are showing the same System Id but a different WACN.
I don't think the two systems or counties (Shelby/Mobile) are related or connected but its possible. Any ideas?
If you are within distance of this freq.'s range see if you can get a signal on it.
If possible decode this site and see what info is being broadcasted.
If you use a Pro96 scanner to decode the Shelby Co. system you will need Pro96com Software version 11.2 if available.
Software version 11.4 will not decode there system using a Pro96 scanner because Multi-Packet decode support
was removed for the Pro96. Sw V11.2 offers limited decode ability due to the Multi-Packet/Multi-Block or Extended Packet info.
Have not tried decoding using Sw-V11.4 yet with a newer type scanner to see if it will decode there site.
I am not sure how or if the decode will work if they are running Phase 2.
If the decode works post any info found.
