AC-coil relays buzz the contacts in step-start service as they close. DC
relays close smoothly in step-start service without buzzing the contacts.
A good stepstart relay is the 110VDC / Heath original. It is too slow
to avoid hotswitching with newer radios, so it should be replaced with
high speed relays. (see schematic on my Web site.) the cost is around
$60.
