Has FM E-Skip ever been received in Hawaii?

gar hi

gar hi

I realize it would take a double hop from the west coast but I checked out the real time Sporadic E maps earlier this morning and it showed something going on between central California and Maui for a short time.

Don't know what the frequency was, however, because I would have had to login and I'm not a member.

It seems like the odds are so slim for any such FM reception but anyone know of any such documented catches?

I've also never heard of EM Broadcast eskip happening in Alaska. Doesn't mean it hasnt happened, but in the half a dozen or so FM DX email/.facebook lists i hang out in, ive never heard of it happening.

Plus, its never happened to me in Alaska... the best i did was a translator 30 miles away in rural alaska a few times.
 
I don't think so. But tropo is possible to California and even Mexico. Shel Remington of Kea'au HI heard Puerto Vallarta and a Colima FM at 3,300 miles on February 13th, 1998 from his 2,600-foot location on the Big Island. I don't believe he is alive anymore.
 
I just did a bit of Google searching. I didn't find what I was looking for, but I did find that you can get tons of info on FM DX'ing by searching "Todd Emslie FM".
I think that he is mentioned on every DX website, board and blog there is.
I thought Todd or Tony might have some examples of North American FM DX in to Australia. Might be worth more looking.
 
I believe Todd has gotten KHON-2 Hawaii (in the old analog days) via multi-hop E-skip from Australia, along with KVZK-2 in Pago Pago, American Samoa.

Norther American FM DX into Australia? Yorue talking over 3000 miles.. i dont think so.
 
E-skip on VHF can travel great distances. California to Hawaii has happened many times.

There are TV DXers in Portugal that have received the Channel 2 in Buenos Aires, around 6,000 miles away.
 
Yes, there is a guy in Portugal who has caught channel A-2 Es many times from North and South America. I don't know if he's still on YouTube anymore, but there were some great videos he posted in the past - both Canada and the U.S. and South America on channels 2 and 3 via multi-hop. It seemed like CKCW-2 in New Brunswick was one of his more common catches.
 
I wouldn't know if Hawaii-California FM skip has happened, but some FM DXer in the UK or Ireland with a good beam antenna has heard stuff from really long distances, including across the Atlantic, and I think if there has been E skip on the FM band it would take a good beam antenna to pick up the Continental US from Hawaii, or vice versa.
 
You may have never heard that F layer propagation is sometimes possible on Low Low VHF. It's statistical, and there is a graph of this in the 1960 NAB Engineering Handbook. Some of these may actually be F layer reflection.
 
It occurred to me now that the path showing up from Maui to California on the real time Sporadic E map I mentioned was 50 MHz MUF.

That's bordering on old analog channel 2.

Later in the day, I noticed multiple reception paths on the map at once from Maui to places farther east in the western US at 50 MHz.

Maybe that means reception above 88 MHz isn't so unheard of after all?

There are some fascinating formulas and graphs in Section 2 of the NAB Engineering Handbook. There are also graphs regarding Sporadic E statistics and probabilities, as well as F2.


Footnote 1 of the section is John Kraus' 1950 edition of "Antennas". In case you don't know, John Kraus' life was part Maize and Blue, part Scarlet and Gray, a Bob Ufer Cognitively Discordant Nightmare! His amateur callsign was W8JK.

I'm familiar with F2 skip and it can get as high as analog channel 2 but it happens during periods of high sunspot activity,

According to this chart, we are now in a minimum period.

The old analog KHON was received in Louisiana once by F2 prop (during cycle 23). It's on the TVDXExpo site.

How did he do that? I know he have a PAL TV, But how did he see it, being in NTSC

Is there any video on it

Many long time TV DX'ers use an HS Publications DX-100, which allows quite a bit of manipulation of video bandwidths and other parameters. The DX-100 then can send an IF output to an FM receiver. Todd uses his high-spec receiver.
The video then goes to a multi-standard monitor or TV.
 
A signal meter on a set with slow AGC is a good test of what kind of propagation you have. With E skip, the signal meter pin will erratically bounce around, but tropospheric is steady. I understand that tropospheric ducting often allows signals between CA and HI.
 
So this topic somehow got me reading about CB radio communications.

I thought CB radio was pretty much dead after the 70's but apparently it's still alive and well.

And what has me interested is that skip happens a lot more on CB (27 MHz) than I ever thought. They call it 'shooting skip'.

Right now, the real time map shows a countless number of paths to and from Hawaii at 28 MHz MUF and many are triple hops.

I was also reading in some CB forums where they say the skip only happens with sunspot activity which would be F2 skip.

Also, the skip on the CB band seems to be a year round thing because the posts in the forums mention skip happening on days in all months.

Anyone know how much of this is true?

It almost has me interested in getting a hand held CB radio but I don't want to do that if the chances are slim I will hear anyone from the mainland or if it's only possible part of the year.
