The sound of a graveyard frequency at night from Hawaii

gar hi

gar hi

This is 1450 kHz.

There are no stations on this frequency from Hawaii and that means the weak chorus of stations being heard are all from the mainland.

That's 2,300 miles or more for stations that are only 1000 watts!

Once in a while, a station will be audible on top of the others for a few seconds at a time but then vanishes back into mix and getting an ID is no easy task.

If you get a loop, you will find you can take advantage of different atmospheric conditions and actually log a lot of graveyarders.

When I was in Ecuador in the 60's, there was no station in South America on most of the Class IV channels after Midnight CST. I had lotx of Gulf Coast stations and even logged and verified some from as far as Wisconsin and Montana.
 
My Terk AM Advantage loop didn't help with nighttime reception on any frequencies. But it helped in the daytime on some.

As someone else mentioned, maybe it's because the PR-D5 already has a very good built in antenna.

Perhaps, a much bigger loop would do the trick.
 
Not sure of the exact size of the antenna in the GE Super Radio II but the antenna in my PR-D5 is 200 mm.
 
Pardon my ignorance (I literally live on the other side of the world), but how do you know those stations were coming from the mainland US, rather than central America, Japan, Australia, NZ etc.

And yes, a hell of a long way whatever.
 
I will chime in with this answer:
Maybe some from Latin America, but the Austral-Asians would be on 1449KHz and would introduce loud 1KHz heterodyne tones.
Remember, outside the Americas, the digits must add up to nine or a multiple thereof.
 
Wouldn't there be some bleeding (in either direction) between 1449 and 1450....even at extreme distances? I haven't had a chance to listen to Gar's video(s) because of an audio issue with my computer. Hope to get that corrected within the next few days....although I have to say, I'm enjoying life without "auto play" at the moment. :)

Couldn't have been Australia or Asia because it was not dark there yet.

Mexico doesn't have any stations that run more than 1000 watts at night on 1450.

As far as Central America goes, I used to live in Tampa, Florida and there was never anything there on 1450 at night other than the usual signature graveyard chorus of stations along with the weak WSDV from Sarasota and any others that came in for a short time were from the US.

With only a handful of exceptions, the Asian and Australian frequencies are not the same as US frequencies. "They" are on 9 kHz separation while the US is on 10 kHz. So most channels are one or the other but not both. Of course, every 90 kHz they are the same...

The Central and South American stations that are easy to hear in Hawai'i are all in Spanish, as are those in Mexico. While there are some US stations in Spanish, if you hear English on the non-overlapping 10 kHz channels, it is the US or Canada.

When you have overlap is when there is one strong nearby station and a close-on-the-dial distant one. With a selective receiver, equally weak signals can be separated fairly easily, particularly if the RX has a choice of bandwidth filters.

Try placing the loop a few inches away from the radio. My PR-D5 is a newer one (with SiLabs chip and twin coil loopstick), but probably it is probably similar in sensitivity and selectivity to yours. If I place the loop (Select-A-Tenna or Radio Shack Loop) next to the radio the is no improvement. If I place it 5-6 inches away from the PR-D5, I get a 1-2 db boost. Sometimes it's enough to help with an ID.

It's at least worth a try.

A one kilohertz heterodyne would definitely be present, from the carrier signals. Would even be noticeable on a PR-D5, a radio with a fairly narrow bandwidth.

I learned as soon as I got it not to place it right next to the radio and place it at around 5 - 6 inches away.

Here's one of my older videos from when I had recently gotten the loop.

But again, I never could get those same results with a nighttime signal.

Ah, for some reason I though Japan and Australia were on 10 khz spacing, like the USA is.
