We're excited to share our Motorola Type II trunking system with you: operated in the 70cm amateur band, it is lovingly referred to as the HamTrunk™!
The trunking system is typically installed in/on T4, a retired fire truck 🚒 that served the municipalities of Baltimore, MD and Waterbury, CT before it came into our possession. It is now used as a mobile radio tower for our system, as well as hosting other partner groups at events.
HamTrunk™ and T4 are sponsored by ARROW: Amateur Radio Repeaters On Wheels.
Detailed programming instructions, system keys, and sample codeplugs are available for a variety of radios:
- Motorola
- ASTRO (ASTRO Saber and XTS 3000)
- ASTRO 25 (XTS and XTL 5000/2500/1500)
- APX (all models)
- EF Johnson
- Legacy models (programmed using PCConfigure)
- Viking VP and VM (programmed using Armada)
