3.5.10 Why do I get IC-746 birdies when I turn on my IC-2KL?
The IC-2KL is at fault, not the IC-746. A noisy, 12 volt switching supply within the IC-2KL
causes the problem.
The supply is in a small, shielded box on the top of the chassis, behind the meter. Cleaning
and tightening the metal box and covers will help. Additionally, Icom recommends changing
out leaky bypass and filter capacitors.
3.5.11 How do I hook up a Yaesu Quadra (VL-1000) amp to an IC-746?
The RF, ALC, and SEND connections are pretty straightforward. The only truly tricky part
is getting the band select data from the IC-746 to the VL-1000. Fortunately, AB4OJ (Adam)
has already forged the way. The details are at:
http://www.qsl.net/ab4oj/quadra/interface.html
He did all of this for the IC-756-PRO-II, but all of Icom's modern transceivers use the exact
same ACC port interfacing, so you should be all set now.
