I have a K3/10 with a 66' dipole in the attic and I am running 5 watts
with incredible reach. From Detroit, I am reaching FL, WA and Ottawa.
But my contacts have been when I answer a CQ. When I call CQ, I do not
seem to get a call back. Any ideas? Thanks in advance. The Reflector

I can't speak for details on the K3. Only generally.
I also have a question regarding asymetric AM modulation
and the K3 - is it
possible for the TX to exceed 100% positive modulation
whilst maintaining
less than 100% negative? Being only new to the AM mode, I
am not sure if it

Using the FM filter for AM transmit has been requested but may or may
not happen. According to Wayne, this depends on whether it can meet
transmit specs and development priorities. I'd like to have AM mainly

But wouldn't that be the advantage of using Gary's RW eliminators - that you
wouldn't have to make them yourself, or do any guesswork as far as
dimensions, etc?
If I had planned on adding more features to my K2 in the future, the RW
eliminators seemed like a good way to go for a very reasonable
BTW, here are a couple of things you can do to achieve a better match
with the KAT3:
If you tap ATU TUNE again within a few moments after the first tune
attempt the KAT3 will go into a more comprehensive tuning mode. It
takes longer but may find a better match.
You may also be able to obtain a
The point was that Gary and Ken have no more Un-PCB modules left. So
now one either has to find them somewhere, or make their own or just not
bother and install the options as they are built. Adding the options
later is not a difficult task at all - solder some headers in and
clip/unsolder
I suppose if I had that problem, I would establish a QSO with someone who
had a good signal then ask them to stand by while you call CQ and ask them
to listen and respond to it. That might eliminate the luck factor.

Just a thought from a PSK beginner, a 3 by 3 CQ in PSK31 is really short if
you do the (IMO) right thing and listen carefully in between each CQ. Just a
few seconds. Same with a CQ in CW at 20wpm or more, you're only on the air
for a really short time. So unless the other station has a pan

You can see most of the PSK section of any band on the software's

This is pure speculation. I've observed the same thing running QRP on

There are multiple reasons you are not getting a response.

If you stripped out the allen wrench, you were applying more force than

You do not want more than 100% positive modulation with the K3.
