Dunno about 477khz it's stone cold silent here... but 474.88 has a 5X8 signal  all full of warbley tones here in Bandon, Oregon right now...

*This transmitting loop has been up in the air here for about eight 
years or so...*

*1. The loop consists of ONE piece or wire and ONE variable capacitor, 
that's it...
**The high voltage wire is el-cheapo on e-bay search;
"Professional Electric Underground Dog Fence Wire 14 16 18 gauge 
500/1000/1500"
Is very high voltage insulated wire and has 9 strands of copper in the 
various sizes...*

will need a decade box or other capacitor in parallel with the variable 
cap in order to tune _way down_ below to VLF...

Once upon a time there was a product called "invisible fence" to keep your dog inside the yard. 
A shock collar was put on the dog and a wire was buried around the property. 
When the dog approached the wire, the collar picked up a signal and shocked the dog.
Dogs soon learned that if they took a running leap across the wire they could go courting or hunting again.
The current way is to have the shock collar shock the dog if he gets too far away from a transmitter on the property - or if the power to the transmitter is lost.
You can see that digging a trench is no longer necessary, and there is lots of wire that has no buyers. This is the "Underground dog fence wire" referenced above.
Personally, I believe in training the dog and owner, not shocking the dog.
Pat

Hi all:

I am monitoring OP-8 on 477 KHz tonite.. Anyone with the program installed, and would like to do so; send a few
transmissions.. If I decode you, it will report back to you if you are connected to the internet..

73, and Best DX to all:

Regardless of its original purpose, Dave's recommendation for this
underground, inground, or direct burial wire makes good antenna wire
because the thick black poly insulation is UV resistant.  I've had an
antenna up for several years using it and it shows no sign of deterioration
here in the sunny South.  I don't know how long it could tolerate long sub
zero winters.  Avoid the aluminum or steel clad wire, and choose flexible
copper wire for extra flexibility.

Here's one example.

Dog-Fence-Wire-45-mil-LD-PE-Stranded-Copper/261598587135?

Dave, and Pat, know whereof they speak.   :-)
