Karl, rub it in with the 80's! Here in Okie land we have been on a roller coaster ride setting record highs one week (75 a week ago) to near record lows just the other day around 10. However, nothing like Lee's frozen condition although we had those conditions just a year ago. I'll have to dig out some pics of a friend's antenna destroyed by ice a few years back and post them here. The weather has been really crazy (just like the lack of sunspots!)
As for the 746Pro, so far I have no complaints although I am aware of all the problems others seem to have experienced with it. I had considered the 756Pro3 and even had the money for it but opted for the 746 instead, saving around $1200 at the time. I guess you never know with any radio and just have to take your chances.
Good luck with whatever one you end up with.
Lee, great shot of your shack. You certainly have plenty of knobs to twist and tweak. I can't make out the device on the tripod. What is it? From the looks of the weather up your way, it may be a while before your beam gets unfrozen.
Hope to work you guys tomorrow.
