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! 73 Roger, DL5RBW -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of DC Sent: Saturday, December 07, 2019 6:28 AM To: [email protected] Subject: Re: [Elecraft] K3S driving an Alpha 86 I have used a K3 with an Alpha 76, 78 and 77DX.
