We're excited to announce that NEAR-Fest Fall 2024 will include an appearance from a Motorola Type II trunking system in the 70cm amateur band (lovingly referred to as the HamTrunk™)!
Visit us at the big red fire truck 🚒 or call us on HT-Primary!
As the system administrators, we hereby give permission to affiliate to and use the system, predicated on following these rules:
- All activity is subject to auditing and logging
- FCC-licensed amateur radio operators only
- Foreign stations operating under FCC authority are also allowed
- Follow all applicable rules
- No political speech
- Have fun!
Users that do not follow these rules are automatically no longer authorised to use the system, and may be inhibited.

This talkgroup is the general-use TG for all communications on the trunk.
This talkgroup does NOT allow emergency calls or alarms.
Please treat this similarly to a general-use amateur repeater.
This talkgroup is a secondary TG for testing and experimenting.
This talkgroup allows things that would not be appropriate on a general-use amateur repeater, such as:
- Emergency alarms and calls
- Sending statuses and messages
- Trying out other system features to see what happens
Compliance with FCC regulations is still expected.
This talkgroup should be programmed as an announcement group (AG).
System-wide announcements from the system administrators will be broadcast on it.
Please do not attempt to transmit on this talkgroup.
Private calls are allowed, but must be performed in the "enhanced" mode (private call with ring). This is to preserve voice channel capacity.
Call alerts are allowed.
