LORAN 100kHz reception with AM transmitter/converter.

[gccengineering1996]

Q: How do you build such a converter? I tried to look up on google for a circuit like this, there is not even a kit for this yet, can you help me find the schematic for this circuit that you constructed? Thanks.

Perhaps you can record the last ransmissions for posterity :

This just announced--

SPECIAL NOTICE

SUBJ: TERMINATION OF ALL U.S. LORAN-C SIGNALS

1. IAW THE 2010 DHS APPROPRIATIONS ACT, THE U.S. COAST GUARD WILL TERMINATE

THE TRANSMISSION OF ALL U.S. LORAN-C SIGNALS EFFECTIVE 2000Z 08 FEB 2010.

AT THAT TIME, THE U.S. LORAN-C SIGNAL WILL BE UNUSABLE AND PERMANENTLY

DISCONTINUED. THIS TERMINATION DOES NOT AFFECT U.S. PARTICIPATION IN THE

RUSSIAN-AMERICAN OR CANADIAN LORAN-C CHAINS

AGREEMENTS.

Two of the LORAN-C chains you're getting are Canadian West Coast, GRI 5990; and U.S. West Coast, GRI 9940. The only station that transmits signals in both of those chains is the George, Washington station. You must have a good groundwave path from George, WA to Tiverton, RI.

Loran is making a revival. It's important because GPS can be jammed easily. It's important because satalites aren't as safe, and cheap.

I think this will be a very big AtoN for people in the technology sector.

I like your videos

well cool! r you sure its safe?

The only wire that's outdoors is the ground, and it's really close to the house and well below the roof so lightning won't strike it. The transmitter only has a range of about 10 feet, so the FCC won't bother me.

G6 - very nice. I've always felt shortwave radios with an FM band could easily include an air band.

I take it the G6 doesn't go down to 100khz? My Degen 1103 goes down exactly to 100khz - so thanks for confirming that noise is LORAN.

[Amishman35]

It only goes down to 150 kHz. I used a crystal-oscillator AM transmitter to re-broadcast the floating voltage at its input. This transmitter doesn't filter out input above the range of human hearing, so LORAN gets through. If you tune to the harmonics of the square wave oscillator, you can hear the input too. I just posted another video of beeping I found at 24 kHz.
