First Student Seattle.

[SCPD]

I usually listen to First Student School Bus Service in Seattle; however lately on their frequencies all I hear is a buzzing... no analog audio. The model radio they use is Motorola CM300d.

Um, if they're using MotoTRBO radios, and all you hear is buzzing, I'd hazard a guess they've switched to....MotoTRBO.

The CM300d is a digital MotoTrbo radio.

They proberly went to DMR since you heard that sound. Alot of First Student busess are going DMR. Did it sound like a machine gun going off?
