Re: LF: W4DEX at 8270 Hz

[Markus Vester <markusvester@aol.com>]

Nice coil solution! And the warning plate on the tower is impressive too.

Joe is on 8270.0075 Hz, Stefan usually on 8270.005, myself occasionally on 8270.0025, so 8270.00 is perfectly clear for you. With GPS-locked carriers and uHz resolution, a small band provides plenty of space ;-)

However simultaneous EbNaut "spread spectrum" transmissions will require mutual consultation. Up to now we've tended to use 8270.1 Hz for that, which produces little interference to the narrow grabbers. 

73, Markus

Great! Now we can dream of seeing two transatlantic VLF signals (you and Joe), side by side.

How did you manage to increase the inductance so quickly?

Best 73,

Redneck engineering.  Added ready made coil of #14 THHN at the bottom:

I believe Joe isn't exactly on 8270?   I can QSY in 0.1 Hz increments if needed.
