Well seeing as you want the tune thru accessory connector, how about adding me to that list too.
I have a Barrett auto-tune antenna which are very common here in VK. These work a treat and the K3 would need to have the tune function reset after the auto-tune antenna finds a match. Although these are rated only for 125W, they are a great antenna and extremely reliable. I have the specs and circuit diagrams available also. I would than have the ability to use the K3 when mobile in the motor home...:-) Gary On 13 April 2011 21:33, John K3TN <[email protected]> wrote: > I have the same combination: K3, ALS-600, MFJ-998.
