I would guess from what you are saying, that you don't have a six meter
antenna, do you?

That would probably explain the SWR problem.

Cushcraft makes a nice 3 element beam which will get you started, but I
personally like their 5 element beam.

Remember the more elements, the sharper the beam is - you might be so narrow
you'd miss the openings!

Also a good 6 meter antenna is stacked halos.  Omnidirectional horizontal
antennas, but stacked for gain.  Each additional antenna gives a "times two"
of power.  Two halos stacked is about 3 dB over a dipole, and three halos
(my favorite) is about 5 dB over a dipole - which is about the same as a two
element yagi.

Of course you could also find the directions to make a quad for six out of
pvc pipe - make sure you use the white pvc because the grey or black has
graphite in it and will mess things up for you!

I bought a new IC-756PROII a few days ago and have been learning to use it.
It works well except on 6 meters and it may be an operator problem. When I
listen on 6 mtrs I don't even hear any noise w/preamp2 on; it makes no
difference whether an antenna is connected or not. I tried ANT1 and ANT2;
also set ANT to OFF to be sure ANT1 was active. Then I tried TX and saw
about 30% power on internal meter; external meter didn't wiggle. I checked
SWR and it was infinite on everything I connected including a commercial
dummy load. The ant. tuner was unable to lower it. It seems the circuit is
not connected to the ANT1 or ANT2. Is there something I need to set to get 6
meters to work?
