That's noting unusual. Almost all amps are sold that way, with
operation up to 22 MHz and a separate user-mod kit that can be
installed by a licensed ham. It's
Yes - Ameritron tube amps have had the cut the green wire mod and

I am attempting to slowly learn to work with CW but at first it is with
a computer program but I am not sure if that is relevant.
I understand the reason for break in as it allows for RX listening
between your TX in case someone it trying to contact your.
The issue is that when using VOX and

You should have the amp's keyin (or PTT) keyed with the K3 KEYOUT
signal. If you have it that way, you are doing it right
Not all amps are capable of QSK because they use big, clunky, open frame

The powercube is definitely a ham amplifier. I know of at least one
owner who is very happy with the one he has but, then, he only operates SSB.
Most amps that use relay T/R switching (and that is *most* amps) do the
clickety-clack thing. I know of failed relays that could not take the
