I don't think there are any VHF wireless mic systems left in the US. Its all gone to 900MHz or 2.4GHz

My comment was with a firmly implanted tongue in my cheek - making reference to a prior thread wanting to listen to his Utility as he say a gauge indicating 60 hz

I am pretty sure it is but I have no real way of knowing. Most of the appliances and such seem to transmit at 60 hz
