Actually, it's certainly worth trying. Not a Vik II or 500, but for goodness

can get any kind of an antenna there. The power of the K3/10 isn't all that

I have an Elecraft K3/10 getting great reception on AM using attic dipole
on 7.290 mHz. Does this mode transmit well for QRP? (I use digital modes
and do not own a mic.)
Thanks in advance.

I'm surprised to hear this. Most people think a single 3-500Z can
produce 750w ICAS without problems.

Joe,
You are quite correct about limiting AM carrier power on the K3 to 25 watts
and AL-80B carrier power to 200 watts. However, according to Ameritron and
Tom, W8JI (designer of the AL-80B), 1000 watts PEP on SSB is the upper limit
as is 800 watts on CW. The key to minimizing non-linearity is

Just thought you'd all like to know that I have been getting GREAT AUDIO
reports from running K3 #1717 on AM, into an AL811H amplifier driving the amp
to about 125 watts carrier. Connecting the K3 to the amp was as simple as
plugging in the relay cable and the coax.

Greetings folks,
I have just posted a video of my K3 on AM and FM on 10 metres (5 watts
carrier AM 12watts FM) and believe it or not on 20 metre AM with 5 watts.
The video was shot on 20 July.
I received very good modulation reports on AM. The K3 on receive is
first class.
