TOTAL ECLIPSE OF THE SUN

The contiguous United States will go absolutely dark for 7-minutes and 12-seconds on Monday August 21, 2017, starting at 9:06 AM PDT.

Blare OnAir Lite has prepared a PUBLIC SAFETY DRILL because there are predictable hazards to be ready for.

Another question arises... what will happen to the radio bands during the exclipse... will DXing go berserk?

Blare OnAir Lite No. 522 ECLIPSE DRILL

The KDX Worldround Radio Website is not always on-line. Keep trying until it's too late.

Well, contiguous in respect

Well, contiguous in respect only to the eclipse path.. You can download detailed eclipse path maps of your particular state (if it crosses your state) from https://eclipse2017.nasa.gov/eclipse-maps

For example, here around Savannah Georgia we are supposed to experience a "near total eclipse", but if I drive about 60 miles to Hilton Head Island (which I may do), than I can experience the event to it's full potential.

Joe Rao, a meteorolist, explains how we can expect our AM radios to react during the eclipse, and request that we email him: Read about it here: http://www.skyandtelescope.com/2017-total-solar-eclipse/how-to-hear-the-...

He says:

"I invite you to tune around the AM dial during the eclipse. Send your results — the station you heard and the time that you heard it, along with your location — to me at skywayinc@aol.com. I’ll compile all the results and report the results of this experiment at a later date."

I may just have to get out my

I may just have to get out my Grundig 450 DLX radio. May scan the shortwave bands to see what I get as well as AM and yes FM too.

 

I'm willing to bet you're going to find some real interesting FM activity because when there was a space shuttle launched back in the 90s when they set up the DirecTV satellites I do remember how FM was and I was picking up stations in Texas while I was in Michigan. Then the DX changed to Florida and I was picking up some good rock stations down there.

 

I made log what I find because I have a funny feeling there may be those running those low-powered shortwave stations during this event so I think you should try listening on 13.560 megahertz and see what you get there as well. Don't forget to scan between 6.9 megahertz and 7 megahertz because this is where a lot of hobby shortwave stations will be at.

I'm planning receiving tests here

So this is Hartford CT and the sun

will be 68 % covered here.  That's

good enough for me!

Ham radio ops will be compiling

data using digital modes and I"m

sure this will be very interesting.

After reading several articles about

how this might effect the AM BCB I'm

going down there.

I want to see how fast the D layer

collapses.

Well I'll be listening on

Well I'll be listening on both 1630 kilohertz and 1710 kilohertz. I'm willing to bet that I will hear somebody broadcasting on a part 15 station.

 

Also you might want to monitor 87.7 and 87.9 megahertz. This is where a lot of hobby broadcasters will be broadcasting on FM. You might get lucky and pick up a real far away station. I don't know but I think it'll be a lot of fun.

 

Next you might want to try 6.927 megahertz. This is where a lot of those free banders transmit down there. I can't remember the frequency of the Crystal Ship but I did pick them up one day.

The Eclipse Live On Radio

KDX Worldround Radio from the Internet Building in the Center of North America has just announce plans to carry the entire eclipse live in stereophonic sound.

Other radio stations are welcome to connect to the KDX internet stream and carry the eclipse for their listeners.

We will be using all four of our microphones.

Carl Blare

OK Carl. I'm not sure if you are serious or not. You could

 do A Blare On Air, you know.

Don't look at the sun.  (I'm not going to.)

But you can take radio measurements and report them.

(Best done with a portable radio outside to get away from

RFI in your house.  Or maybe even try your car radio outside.)

You can look at the sky but not at the sun, itself.

(I know NOTHING about sun filters.)

Sounds like a lot of fun.

Taking Levels

It is not easy to set levels for an event that cannot be put through a dry run.

One thing I do know, NEVER point a microphone directly at the sun. It can give your ears a serious tan.

If you play it in your part

If you play it in your part of town and me in my part the folks midway between us get that audio-corona effect.

I'm flying into Perryville, MO to take it in at 100%.

What you need to do every now

What you need to do every now and then is mentioned the part of town that you're in. That way if a listener wants to report that they picked you up they could. You could get a PO Box number and have them send letters to that address.

 

I'm sure FM will be affected as well. So this could be a lot of fun if you know what I'm talking about.

Some eclipse results

I'll tell about the radio aspects

in a second.  I observed the eclipse

with a pin-hole projector made out

of a shoebox.  Rather than explaining

how that's made - - I'll just say that you

can Google it if you'd like.  Even though

the sun was only 68% covered here

in Connecticut - it was a blast!

There were some radio changes on

the AM BCB - - not that obvious, 

however.  I wish I had checked the

daytime conditions over a period of

days to get a baseline.  There is a 

Maryland station on 1690 a couple

of hundred miles southwest of my

location. It came up in strength when

the sun was covered to the max here

- - again - - at 68%.  I found no other 

obvious changes on the regional

or clear channel frequencies.  

However - some of the local channels

- - 1450 and 1490 kHz - - in particular 

- -  DID change.  THOSE channels have

many stations - - hundreds - - scattered

around the U.S.   So there are multiple

signal paths involved in this experiment

- - and some were effected by the 

eclipse darkness path.  1450 and 1490

started to show changes.  Instead of

the normal one or two stations - the

channels started getting crowded.

There were multiple stations - three

to five - or so.  It was really cool!

It sounded like sunset conditions!

Very interesting!

Best Wishes

What you observed makes sense

What you observed makes sense, Bruce.

The eclipse removes most of the sun's extreme UV radiation, which ionizes the atmosphere.  It would be like going to nighttime conditions, and then back again when the eclipse ends.

I was monitoring the 6 meter amateur band at the time, and noted no changes (at least, no increase in signals, hard to determine a decrease when there's nothing there), which again makes sense.  That band goes dead for the most part during the evening.

Hello Mr. Artisan

As a ham, I love 6 meters.  Currently,

I have nothing to receive that band,  but

I read the blogs about it.   I guess many  

6 meter guys are transitioning to JT65.

Amazing contacts are being made with

this mode, many 6 meter ops are 

using low power and indoor dipoles

in attics.  Well, I don't want to hijack

the thread.  Best Wishes sir!

The D Layer

I just thought I'd mention

the trusty D layer which does

it's job every day of attenuating

upward travelling AM BCB radio

waves.  When this happens, this

"D Layer" portion of the ionosphere

stops AM radio skip from happening.

So there is very little or no AM radio

"skip," but at night - Mr. D Layer vanishes,

and AM radio DX skip occurs.  DXers

love this, but it's a big headache for

AM radio station management, who

must lower power and do other

things to minimize co-channel

interference.  Artisan Radio

made reference to this layer in a

recent post here.  I am part of a bunch

of people who are interested in this

sort of thing - the idea was to see

how fast the D layer would

vanish in the darkness of

the eclipse.  There is much

more to this story, but it's

late and I've run out of pages.

It sounds like something Carl

would say.

7 years from now...

There will be a total eclipse here in Ontario Canada in 2024.

Hey Mark

Yikes!  2024!  I'll be able to use my

pin-hole box thingie again!
