Is this online calculator (link below) sufficient compliance with ?97.13(c)?

Iitoi-

It is according to the write-up on the right side of the page. I
suggest you check out the FCC's OET Bulletin No. 65 via the link there.

Also at the FCC web site, OET65 Supplement B references a fairly simple
BASIC language program that does the same thing. I tried it, and was
able to run it using Chipmunk BASIC on my Macintosh computer. Quoting
footnote 12 from Supplement B:

"12 For example, a power density "calculator" has been developed by
Kenneth Harker, KM5FA, and can be
accessed at the following World Wide Web site:
http://www.utexas.edu/students/utarc/. This program is based
on a C version of a public domain BASIC program written by Prof. Wayne
Overbeck that appeared in the
January, 1997, issue of CQ VHF. The source code for this program may be
downloaded at:
