Call 0345 2300 599Unlock TETRA GSSI User Group Filtering on compatible AOR digital receivers with this official activation key.
This PRO feature allows supported AOR receivers to use GSSI, or Group Short Subscriber Identity, to identify and follow specific TETRA user groups. Instead of simply receiving active TETRA traffic channels in T-TC mode, the receiver can selectively follow chosen talkgroups where the relevant TETRA signals can already be received and decoded.
Please select the correct activation key option from the drop-down menu before ordering.

TETRA GSSI User Group Filtering
This activation adds targeted TETRA GSSI user group filtering to compatible AOR digital receivers.
Instead of simply receiving active TETRA traffic channels in T-TC mode, the receiver can use this activation to follow specific talkgroups using their GSSI, or Group Short Subscriber Identity. This is the identifier used to distinguish a user group within a TETRA network.
With TETRA, the frequency and time slot can change from one call to the next. This can make it difficult in normal T-TC operation to continuously follow the communication of a specific group. With GSSI filtering activated, the receiver can selectively choose detected groups and follow their subsequent communication, provided that the relevant TETRA signals can already be received and decoded.
The activation key is generated for a specific receiver serial number and cannot be transferred to another unit.
Important Ordering Information
This activation key is generated using your receiver’s serial number.
After placing your order, please email your receiver’s serial number to:
If you do not email us your serial number, there will be a delay in issuing your activation key.
The licence key will be sent by email to the email address provided with your order. No physical data carrier, cable, accessory, or printed key is supplied.
Please Note Before Purchasing
Before ordering, please check that TETRA voice signals in your area can already be received and successfully decoded by your receiver in T-TC mode.
This activation extends the receiver’s existing TETRA functionality by adding targeted selection and tracking of GSSI groups. It does not enable decryption of encrypted TETRA communications.
Reception and decoding must only be carried out where lawful and authorised.
Important Note
This listing is for an activation key only. No physical product is supplied.
