"The K3 controls the THP amp okay using a cable from ArraySolutions: K3-ACCconnector-to-THP. I want to add an MFJ autotuner because of reflected power from the 160- and 80M antennas, and an antenna switch for convenience. Will a KRC2 with V1.4 firmware be helpful? What would the cabling need to be? Tia & 73, Dave Windisch, W8FGX"
Dave - I use my K3 with a MFJ-998, an ALS-600 and an Ameritron RCS-12 switch - kind of a similar setup to what you are looking at. You'll need a SVGA splitter cable so you can simultaneously feed the THP amp and the KRC2. Make sure you get a cable with all 15 pins connectied through (Array Solutions sells one). The KRC2 will drive remote switches like the Array Solutions SixPak or the Ameritron RCS-8 or RCS-10 (I'm only familiar with these switches). The MFJ-998 autotuner has an amp disable feature whereby you feed the amp-key output of the K3 through the MFJ-998 and on to the amplifier, and so the MFJ-998 will take your amp off-line before it starts tuning or if you exceed a pre-set SWR threshold,. So you'll need a RCA cable from the K3 amp-key out to the MFJ-998, and another RCA cable from the MFJ-998 to the amp-key input on the THP amp. The MFJ-998 also puts out a ground when it gets ready to tune, which can be used with some transceivers to put them into a low power CW tune mode automatically (the K3 doesn't have this capability yet - but I THINK it is coming eventually). I have a review of the MFJ-998 on my website (www.ad5x.com).
