John, I have used both MFJ 993 and 998 successfully. I have 12v for them and send one coax to them. I don't rely on anything but sending 10 watts via K3, etc., to the tuner and await the OK SWR to reflect on my W2 wattmeter. I currently only have the 998 in service. I prefer the 993 as it takes less power to tune. I am going to sell my 993 as it handles only 300 watts. I send out 500 so cannot use it. Hope this helps.

I have seen several controllers for the ICOM AH-4 tuner. My questions are about operation with a K3s. 1. Is there a limit to the time that 10w of RF can be sent to the AH-4 via the K3s Tune button? 2. All circuits specify a momentary switch, but does momentary mean 0.1sec, 1.0sec or 5seconds? Does the time matter? 3. When the complete signal returns from the AH-4 should the Tune RF or the momentary be terminated immediately? 4. Is there a combination of momentary or Tune RF that will damage the AH-4? I have an AH-4 which worked with a home built controller for some months, and then became operationally intermittent and final fails to work at all. That makes me gun-shy, about buying another even though the AH-4 gets excellent reviews on eHam, almost all of which are based on an ICOM rig control.
