The rule of thumb, really old saying, is buy the power supply with a higher amp rating (25amps). That way you don't run the risk of frying the radio, or the power supply. That way, if you want to do simplex at 65w, the radio and power supply will be very happy)the jetstream is a 12amp (15amp surge) and the radio is 15amp @65w
assuming that i am not operating on 65w all the time, would this be a safe combo? or should i step up to a 25w power supply (JTPS28) to error on the side of reliability?
