K3 #157 (factory-assembled) ordered on May 2 arrived on Xmas eve. Here's my question. How do you connect an ICOM PW-1 amplifier to the K3. I know that the ALC is a yet to be resolved issue. I have an IC756ProIII already connected to the amp so the K3 will be the second exciter. Has anyone connected a PW-1 to a K3 yet? I have to run a cable from the send2 connection on the PW-1 but what does it connect to on the K3. There are no amplifier connection diagrams in the K3 manual (yet, anyway!!)
Incidentally, in a side-by-side comparison, the K3 receiver wins hands-down - no contest. I really want to try the K3 with the PW-1 in the Stew Perry Challenge this weekend.
