The N6TR software has had this from the start.

How true!

  If you've ever driven a car (such as a Bimmer, aka BMW) with truly 
sensitive steering (oversteer), and that at the same time provides plenty of 
feedback from the road/tire/steering-wheel interface, and then drove a big 
fat  American piece of iron (newer models excepted?), you'd intuitively know 
exactly what Patrick is talking about!

  Somehow, I just can't imagine the 'magic' of slowly tuning a VFO across a 
wide open band during a CONTEST being replaced by a PC human/machine 
interface of some sort (mouse, track ball, etc.).  Then again, after going 
through school in the early 70's, hard on the heels of the wild (for some), 
'60s, I never thought there would be such a thing as political 

  Guess we'll have to wait and see what the future will bring.

Well, not really a summary...

I bought an Omni 6 yesterday.  

My decision is based primarily on two things.

1)  $$$
2) RX

100% of the people that responded (that had used both) said the Omni-6 RX
was as good as the FT1000 (most said better).  Most of the complaints about
the radio have already appeared on the reflector, and most seemed pretty
nit-picky to me.

What was amazing and new to me about this antenna was especially its
performance during the 0300-0900Z time.  I would put it due north and
the whole world would call in and everything seemed to be coming in
over the pole, not just the European sunrise gang, but everyone.

A VK would call in, so, flash, switch to the antenna pointed at VK,
hmm, nothing.  Switch back to the big north antenna, ahh, there he is,
579.  Same thing with guys in the Indian Ocean.  And the Europeans
were better on this antenna than on the Europe stack too.

And on paths that traditionally seem like high-angle paths, like West
Africa at 2200Z on 20.  Giant pileup for J52US (non-contest), so we
point every beam at him and do a side-by-side-by-side comparison.  We
can't crack the pileup with any antenna but the high one, which gets
through on the first call.

Why did it work so well?  Dunno.  Latitude and Longitude?  Maybe.
Local terrain surrounding the tower.  Maybe.  Worked great for us.
