Chuck, I use the key 2 line, key1 is jumpered to aux. I put a steering diode inside the qsk-5 as well, but I don't remember where! I suggest you call or email Ameritron--they'll tell you how to do it. The qsk-5 manual is confusing.
8ms delay works fine. One other warning--if you are using a W2 with the swr lock feature, DO NOT break the ptt line from the k3 to the qsk-5 switch to go through the W2. If the w2 goes into swr lock you will fry the qsk-5 switch and see the fuse lamps light up the room. Instead, break the line going from the qsk-5 to the amplifier ptt to go through the w2. Ask me how I learned this! The qsk-5 works great with the k3--silent, smooth QRO QSK. I use it with my AL-1200. 73, Eric WD6DBM Sent from my iPhone ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
