[... I post an idea, Richard explains why it wouldn't work ...]

Jack Thank you for the very detailed explanation. So much for that
Jack idea. :-)

Irv You aren't the first to think of that idea, and if you stick
Irv around the newsgroup long enough, you will find you are not the
Irv last! It's not a dumb question -- the only dumb question is the
Irv one that isn't asked.

When I think of something I haven't heard anyone else discuss, and I
haven't seen mentioned here or in other online fora, I try to research
it a little online and see if I can learn more about it. With this
one, it was too tempting (because of the AM example) and the stuff I
had read about Sommerfeld grounds in the NEC2 source and also comments
seen on Mr. Cebik's site (usually associated with graphs of antenna
patterns made with different types of ground) led me to believe that a
quasi-infinite plane of salt water goodness would be a huge boost. It
sure beats placing a layer of aluminum foil or steel plate over the
backyard. ;-)

Hi Jack,

Let's not lose track of why this is true, rather than fixating on the
downside of alternative illusory explanations. We have DXers here
frequently gushing about their shore installations.

We also had reports from one fellow who maintained a regular schedule
with an Aussie who worked CW mobile in his car coming home from work.
Our man here could literally see the variation in signal strength as
he approached or moved away from the shore down under.

Now, this report is typically known as anecdotal. However, when you
can repeat the observations and correlate them to your hypothesis (as
they did), then such reports gain materially.
