I know this isn't quite "emergency", but I thought it was kinda neat to talk about.

Last night 04/11/2012

We had about 9 people on 7.208 talking all together telling stories. . .

What is unique about this, it was at 11 PM CST. What is even more unique, is the distance that was being covered.

For my station only. . .I had. . .
California (1500 miles away at least)
Texas (330 miles away (Denton Tx))
Nebraska (150 miles away)
Topeka (130 miles away)
Tenn (Memphis) (Not sure of the distance maybe 600?)
Miss (about 900 miles away)
Fort Smith (about 240 miles away)
Manitoba CAN (not sure of the distance from Wichita)
Longmont Co About 450 miles.



All were coming in well over 9 db for about 1.5 hours of chat, before people started signing off for bed.

The unique thing of it all, is, usually the band is either short or long, this night it was both, with superb conditions and strong signals throughout the night.

Just shows how a frequency can act.

For what its worth, it sounds neat to me too. 40 meters is in the HF band, correct?

yes 40 meters is considered the HF band. 40 meters is 7 mhz.

speed of light divided by the meters. . .= frequency
300,000,000 / 40 = 7.5 mhz

300,000,000 / 2 = 150 mhz which is the 2 meter ham band of 146 mhz

It is really nice to have conversations with so much talent out there.

Dwayne,
You threw me a curve ball on that one. I always looked at the speed of light in the MPS (Miles Per Second) range 186,000+/-.

Just learned a new factor, MPS or meters per second. Thats FAST, huh?

I've been getting fast balls of about 300 hundred million meters per second. Don't even see them coming. Well, back to low crawling.
