This would be a great help! I just know myself, and sooner or later I will TX full power into the untuned antenna/tuner.
Though the rigs rx performance is far from ideal, the current setup has me pretty spoiled. The Icom trx will initiate a tune of the AH-4 at low power if I have changed frequency more than 1 %. The JC-4s I have on order works on the AH-4 protocol too. Just looking to add an amp to the station when I upgrade and the Elecraft's have my eye.

No AH-4 is involved, the AH-4 is designed for the 100-watt category. The ICOM transceiver sends and receives the same signals as it would with an AH-4. But it's the Elecraft ATU, not the ICOM AH-4. If you want to use a remote tuner, it should be capable of handing the amplified output, the ATU tuning negotiation should be between the exciter and remote ATU (which could well be the AH-4 protocol), and the KPA1500 can be used in its ATU bypassed configuration. We will be on the lookout for ways for the KPA1500 to help with this, like bypassing the amplifier when ATU tuning. 73 de Dick, K6KR -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-bounces@ mailman.qth.net] On Behalf Of Michael Zabel Sent: Tuesday, June 13, 2017 10:43 To: Elecraft Reflector <Elecraft@mailman.qth.net> Subject: Re: [Elecraft] Seeking input on KPA1500 station configurations Hello group, This is my first post here, but have been reading the mail for a while. I currently do not have any Elecraft gear, but have built a K2, and owned KX1 and KX3. I am considering upgrading my station in the near future and am interested in the control possibilities of the KPA 1500. I currently use an AH-4 for remote tuning of a non resonant vertical dipole that I use on the upper bands, and have on order a Stockcorner JC-4s kilowatt remote tuner to replace the AH-4. To the topic here, I am interested in the mention of a connection for the AH-4 on the KPA 1500 and and what it's use would be given the mismatch of the power ratings of the two devices? Now on to the station setup I can imagine... It would be useful in my station setup if the KPA 1500 could sense a frequency change and initiate a 10-20 watt tune cycle with the JC-4s before going back to online status. Ideally the KPA 1500 could do this without communication with the exciter making that interface universal. Alternately, with the K3(s), any tune initiation from the transceiver could cause the KPA 1500 to initiate a tune cycle with the JC-4s with the KPA 1500 in bypass. Or even more ideally, Elecraft comes out with a fully integrated remote tuner to match the KPA 1500 for those of us who need the wider matching range in our urban antenna restricted situations. A wide range tuner in the shack would also work, but then you would only want to do that with some very low loss coax like 7/8 Heliax. Thanks for the opportunity to give input and for the example you set as a company. 73 de KV4TT - Mike On Jun 8, 2017 7:25 PM, "Wayne Burdick" <n...@elecraft.com> wrote: > The KPA1500 has very flexible I/O, and plenty of space for adding new > control features in firmware.
