Ed, I did the internal even though I use a remote tuner at the antenna feed for several antennas as well. The internal tuner matches the load from the transceiver as the impedence does change when going through the amp, but the biggest deal is that I get a low power tune to the remote tuner before I bring the amp on line.

Cole Sent: Friday, January 28, 2011 3:50 PM To: Elecraft@mailman.qth.net Subject: [Elecraft] ANT2 port w/o Tuner Ross, etal: This had been discussed when I first got my K3/10 last spring. I chose not to get the tuner since I was also not getting the 100w option and have a 300w ext. tuner. Subsequently, I bought a 2kW manual tuner for future use with amps (300w sspa and possibly a HB 8877 later on). I have 17 antennas at my station so there are certainly more than the K3 can switch, but I do run separate amps/antennas on HF and 6m and that entails manually switching cables. A second antenna port (call it ANT2) would really be useful for quick switching. I have a 6-pos coax switch for selecting my HF antennas. I kept an e-mail suggestion on how to implement a second ant (can't put my finger on it right now) with thoughts of building it (and if there was interest offering it as an aftermarket kit). But there was some involved circuitry to handle switching so not sure what it would cost. If I would guess it would likely be $100-150 so would anyone chose that over just installing the internal tuner? I am really overloaded with other projects so this one will not see daylight for another six months, at least. 73, Ed - KL7UW -------------------------------- Message: 47 Date: Fri, 28 Jan 2011 10:37:56 -0500 From: Ross Primrose N4RP <n...@aiko.com> Subject: Re: [Elecraft] FW: K3 Feature Request Cc: elecraft@mailman.qth.net Message-ID: <4d42e2d4.4070...@aiko.com> Content-Type: text/plain; charset=windows-1252; format=flowed What I'd really like to see is a second antenna port that I don't have to pay $300 for since it's bundled with an antenna tuner I don't want/need.... 73, Ross N4RP 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-1.4kw*, 432-100w*, 1296-testing*, 3400-winter?
