I never heard of AM, GL!  When you mentioned K6STI in your post I
immediately thought of YO and AO. I used both a lot 15-20 years ago with
great results.

GM John… nope -- AM for Antenna Model, an older program written by a now SK.

Dan —  I did read that paper — slowly and with great interest. I did email
Greg, but didn’t realize the .ez files could be read by AM.  But, I have
another fellow who had been modeling the Moxon 40M 2 el on AM and he is
sending me the file.

Looks like I will have something to work with.  I haven’t used AM at all,
even though I have had it for a long time.  I will have a learning curve,
to be sure. My last extensive modeling experience was with YO and Minninec
15 years or more ago.   — I miss them !

I loaded the old AM CD on my Win7/64 O/S last night and it runs!!  Thank
God for small favors.

Thanks for all of your advice.  I appreciate it.

73,

Dave, K4TO
