I think the problem is not elecraft rigs but amplifiers that have
unreasonably slow switching times.
10msec or longer is unreasonably slow and I think it's 'unreasonable' to
blame the manufacturer of the radio because the amp manufacturer saved a
few bucks and used a cheap, slow re

subject after a few days of discussion on this list. We don't even know if
they could easily make the modification in the firmware.

look for a hardware modification to my amp.

Bob speaks the truth here. The K6XX fast relay circuit
is the answer.
The problem with Elecraft rigs switching Ameritron amps
has existed with the K2/100 and, so it appears, now with
the K3/100.
I have had the K6XX fast relay circuit in my AL-1200
working with the K2/100's. No KPA-100 shutdow
I rely on my MicroHam Microkeyer to key the rig and amp. You can set the
delay in the MicroKeyer.
You can also insert a half character space at the beginning of your CW
macros so there is a slight delay between going into transmit mode and
actually
transmitting. In the N1MM contest softw
Or rebuild the amp with faster relays like the Jennings RJ1A.

I am using my K3 with an AL80A...basic amp with the same relay as many of the
other Amertrons use. I have seen no issues at all. Also, you might look at

You can still use the amp by manually activating the transmit switch on both
pieces of gear. I do this with one old rig I have. Not the nicest solution but
it will work By the way I have the QSK add on switch and it works real nice

KEY OUT on the back of the K3 is for connecting to an external amp.

I received 59+20 and excellent audio from central europe. ... How do I
get the K3 to trigger the relay in my Ameritron AL 1200?.

If you're 20 over in Europe, you don't need an amp!! :-)

Hi Tod,
One question remains and it is probably ridiculously simple but I can
not see it. How do I get the K3 to trigger the relay in my Ameritron AL
1200?. I see no connection for a cable to the amp nor nothing in the
config menu.
I don't know the Ameritron AL but KEY OUT should be what you a
