Well, it will be interesting to see if I can get this sloper working at
all.
We did some work on it today, and it is starting to look better, but it
still needs to be tweaked quite a bit.
I also am finding that it will be very narrow. That's not a surprise for
me, but I'll have to think about where on the band I'll want to operate to
get the most use out of it once I get it tuned.
