Bob is right, I have even loaded a standard G5RV on 160M to make my first top band QSOs with the K3 at around 100W. I was not working the antenna against ground. It is an amazing tuner, well done Elecraft. 73 Doug EI2CN

I've never encountered any of my crazy antennas that it wouldn't match. 73 Bob, K4TAX On 4/20/2020 8:35 AM, Charlie T wrote: > Well this MAY be a valid question, since I believe for example, the IC-7300 > and/or IC-7610 have an "emergency" mode where the power is cut back to 50 > watts and the allowable tuner's SWR range is extended from its normal full > power mismatch capability. > If I remember correctly, its only 3:1 at 100 W, but will match an "emergency" > use antenna if you have to. > > 10: 1 capability DOES put some hefty restraints on an internal tuner. > > 73, Charlie k3ICH > > > > > -----Original Message----- > From: elecraft-boun...@mailman.qth.net <elecraft-boun...@mailman.qth.net> On > Behalf Of David Bunte > Sent: Monday, April 20, 2020 9:03 AM > To: Charles Sells <char...@sellsfamily.net> > Cc: elecraft@mailman.qth.net > Subject: Re: [Elecraft] KAT4 > > Charles - > > I don't "know" what the power handling capabilities are, but think I can > safely assume that if it is in the K4 it can handle the power of the K4.
