Hi guys,
I just purchased a new - in - box RCI 2970n2 to use for 10 meters in my truck. It turns out that it is old stock from 2012. Turns out that it seems to be one of those that was delivered with everything set too high. This radio was drawing over 50 amps, with about 150 watt dead key. The amp gate voltages were set at almost 6. I had a shop turn them down to 3.8v and now the deadkey is about 90 watts with almost 200 watt peaks on am and ssb. If I turn up the AMC pot to about 100%, the radio will still draw over 40 amps and kill my big MFJ power supply. I am getting many different answers about the gate voltages. If I want to have a 100 watt deadkey, as what the stock specs say, what should the gave voltages be? The spec sheet for those mosfets say no more than 4 volts, some techs say 6 volts is ok if in tandem. If anyone could send me the service manual or alignment instructions, I would really appreciate the help.
