This afternoon Mercy Air 34 went into service at Paso Robles Airport. On their instagram feed they showed a flight crew member making radio contact with AirComm via a handheld radio, then another snippet showed another quick video of them going into service via radio with San Luis. The question is what radio frequency is being used for handheld radio contact with their dispatch center? The dispatch for Mercy Air is in the midwest, and so there must be a VHF radio link via internet somewhere, but curious if anyone knows what the VHF frequency is.... yet.
