Morgan,
The amplifier will actually be outputting its full rated 1500 watts PEP but because of the 375 watt carrier the heat dissipation in the amplifier and power supply may be to higher than they were ever designed or tested for. If I were you I'd limit the KPA1500 carrier output power to about 200 watts, that should be safe. 73 Frank W3LPL ----- Original Message ----- From: "Morgan Bailey" <[email protected]> To: "Louis Fiore" <[email protected]>, [email protected] Sent: Thursday, February 4, 2021 7:22:13 PM Subject: Re: [Elecraft] KPA1500 on AM The max that you can legally run is 375 watts carrier. That on AM will get you 1500 watts PEP. YMMV. I do not know the spex on the 1500 but that may put you in the ballpark. Understanding linearity, for AM is covered here: https://www.w8ji.com/am_linear_amplifiers.htm If you want to run AM, this is where I would start reading. 73, Morgan NJ8M BS + MS + $2.98 = COFFEE Real Life Experience = Priceless, says the man who set his back yard on fire with a bread board tuner loading a 160 meter inverted L with 1000 watts.
