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. I enjoy troubleshooting radio systems and coverage problems and helping people sort out radio issues. You can reach me at radio@spectrumlookup.com or on LinkedIn. Please mention SpectrumLookup and your ZIP code so your message doesn't end up in my spam folder.

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 some donation links: PayPal 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.
