The Vacaville 800 trunked system has been failing on and off for about a week now. Right now it is in failsoft, but that isn't working, nobody can talk. Last week when it was failing it would not even go into failsoft. This right in the middle of a major grinder on I-80 with required Vacaville fire to land Calstar in town. It least fire has vhf county radios, PD has nothing other than cellphones at this point.
