Q#1 Constantly running the K2 into 3:1 SWR not a good idea. It will work (for how long?) but will work a lot better (and perhaps longer?) into a better match.
Q#2 Yes, in all likelihood, the antenna tuner (antenna tuners do not "tune" the antenna - they just provide impedance matching between the rig and the load) will provide the needed impedance match for a near unity SWR. Q#3 The antenna tuner in the Icom 756 Pro III should handle the impedance match. At least mine will. Give it a try. 73 es gud dxing -- Don N4HH -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of George Sent: Thursday, April 19, 2007 12:27 PM To: [email protected] Subject: [Elecraft] SWR Question Q # 1: My homebrewed single 3-500 tube linear has no tuned imput circuit. When I drive it with my K2, the K2 is working into about 3:1 swr, and indicates HI REF, but seems to suffer no harm. Is that too high an SWR, and does this condition lower the quality/purity of the transmitted signal?? Will it do harm to the K2? Q # 2: If I used an Elecraft antenna tuner, would it resolve the problem and lower the fig to 1:1?? Or does the tuner only work with antennas at the other end? Q# 3: Any idea how the tuner in the Icom Pro 3 would handle the same situation? Still having lots of fun with the K2 after 2 yrs.
