Ameritron AL-811H and Elecraft K3

[Ramon Tristani-2]

I am considering using my K3 with an Ameritron AL-811H linear amplifier. Yeah, I know, the KPA-500 runs circles around it… but budget is tight here. Are there any interface problems that I should be aware of? If so, are there any fixes for them? Please let me know. Thanks.

Ramón Tristani, NQ9V

Very straight forward to use a tube based amplifier. I ran an AL80A for
a year with the K3 before I took the expensive leap. RF out of the K3
into the amp - out of the amp into a tuner - out of the tuner into the
antenna. A PTT line from the K3 to the amp. That is all you need.

Be sure to turn off the K3's internal tuner, if so equipped. Be careful
about over driving the 811A tubes. That last statement means _READ THE
INSTRUCTIONS_.

500 Watts is 500 Watts, regardless if it comes from some old inexpensive
tubes or from a very expensive solid state amp. Don't fall into the 700
Watts trap. The difference of an additional 200 Watts will never be
noticed at the receiving end.

I've used my K3 with both an Ameritron AL-800H and Ameritron ALS-1300 with
no interface issues whatsoever.

Mine works perfectly, but I do NOT connect the ALC line.
I only connect the Relay line..73   Ken  VE3YK

I use an AL-811H and the K3.  Just use a RCA to RCA plug to key the amp from
the K3.  I have my K3 setup to 50W.

No issues.

Ramon:

If you do any CW, you might want to experiment with the TX DLY
settings. I have seen where many suggest changing the setting from
008 to somewhere around 020. You will have to
find which setting works best for you. Other than that you should
have no problems using your amp.

It works fine, but if you're a cw op, don't expect QSK operation without
some extra hardware. With my AL-811H, I also used the Ameritron QSK-5
(with appropriate mod to AL-811H) to achieve QSK. It worked very well --
but not *quite* as very well as the KPA500 which I'm using now  ;-)
