1. How does the K2/100 key an RF amplifier (AL-811)?
I have a Heil footswitch with a second cable for
amplifier keying. But, would prefer to use keying
from the rig itself.
It has a built-in transistor switch that will switch +200V at 1A. It goes low
at least 15ms before the RF starts flowing and has an adjustable hold time.
2. How is ALC sent from my RF amplifier back to the
K2/100? I've reviewed the K2/100 manuals and cannot
find how it is done. Maybe it really isn't needed.
Amplifier ALC isn't supported. My feeling is that it isn't needed, especially
in view of the K2's closed-loop power control system.
3. How do I adapt my Heil Headset Pro and Goldline
microphones. They currently are used with an
IC-746pro by using a Heil adapter cable. They now go
thru a homebrew switchbox with the adapter cable
between the rig and switchbox.
Sorry, I'm a CW operator! But lots of guys are using them.
I cannot see any other major problems. I've wound
baluns and view winding toroids a bit tedious but
there is nothing like "rolling your own." My
background includes professional soldering training
and experience. I have a scope, DVM and other minor
pieces of test equipment. Am I over looking any major
areas that need to be covered before starting?
Nope, just follow the instructions carefully and don't work when you haven't
slept for the past couple of days and you will do fine. And if you have a
problem, there's plenty of experienced help available.
