Need help with a radio system?
I'm Ty Calta, KF4DLA, Director of Service and Engineering at one of the largest Motorola dealers in the US. I'm a former Motorolan who traveled the world fixing broken radio systems, and I've worked in land mobile radio for more than 28 years. I specialize in MOTOTRBO, with many years on Capacity Max, Linked Capacity Plus/CPMS, Capacity Plus/CPSS, IP Site Connect/IPSC, and conventional MOTOTRBO. I enjoy troubleshooting radio systems and coverage problems. You can reach me at radio@spectrumlookup.com or on LinkedIn.
This is a personal project that costs $25/mo for hosting and $200/yr for developer time out of my pocket, so if you feel led to help defray some of those costs, here's a donation link: Buy Me a Coffee. Please don't send anything you can't afford. I'm grateful that radio, and a little technology, keep bringing us together.
