Roger...20M has been very active all night. There are stations from all over
the United States calling CQ. Even at three in the morning.
I'm sure you can't hear them, but would you care to once again tell us, and
them, how this cannot be so?
I bet these Field Day operators would be more than interested in hearing you
explain to them that 20M is not workable in the evening and early morning
hours.
If they doubt you, tell them that you are a twice-tested Extra and that you
know whereof you speak.

Tell them Roger sent you.
