Bob -

Almost there!

W5WW and myself  have a  two-high stack of 402CD's at KC5FU we intend to
convert to Dave's Moxon shortly, partly based on neighbor (K5MR) great
reports after installing one of Dave's "ground-up" Moxons (at 140ft). But we
won't actually do the modified 402CD versions until we finish (75% done at
the second) building one of the "ground-up" versions. Then we will do the
"take one down, put one up" change-out routine for the 402's...so will have
story to tell...soon....I hope!
