Press:
For what little it may be worth...
The ARRL should either already have, or should soon have, the
text/diagrams/etc. from Walt's QST series "Another Look At
Reflections" somewhere ON their web site. I scanned it in
about 8 months ago, sent it to them, and they said they were
in the process of getting it up and on-line.
I still have the complete series as an MS Word for Windows 97
.DOC file (about 500kB, if I recall), if anyone wants it. But
PLEASE, first see if you can get it from the ARRL. That way
I won't have to send it to you over MY modem.
