[Elecraft] K3S driving an Alpha 86

[Roger]

No problem with the ALPHA amplifiers - the switching voltage is approx. 24 V
@ 350 mA. The K3S MOSFET switch will switch up to 200 V (absolute MAX.!) and
several amperes.................

But to make sure connect a voltmeter to the PTT socket on the amp and
measure the voltage then switch to current measurement and switch the
amplifier to TX with the multimeter. If both readings (voltage and current)
are within limits then you are absolutely safe!
