Wow! That's strange. I'm glad I'm careful with mine though with some of the
antenna setups I've run at special events on my 706, it's a wonder I haven't
done anything like that yet. I do have fun with that radio though, even if I
think it is the worst receiver of all of my radios. The old MkII was a lot
worse than the MKIIG I have now though. This receiver is tolerable and the
auto notch is by far and away better than others I've worked with though I
find all Icoms have a great auto notch filter, those that have one anyway. I
should dig out my 706 1 of these days, I think the last time I used it was
October for JOTA. I should set it up in here for a couple days I just don't
know where.
