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.
