[Elecraft] K3S and VLF

[wa9fvp]

I have a special antenna setup that allows me to receive VLF frequencies down
to 20KHz.  Believe or not, down that low, there are encrypted RTTY/MSK
signals that are used by the Navy.  I decided to try My K3S and it's
"lowerfer" receive capabilities.  With the K3S tuned to 292.681KHz, I was
copying "M823 Differential GPS".  Boring stuff but using a PC program called
"Sorcerer", I was able to copy the data.  It was also boring stuff but I
wanted to test the K3S's VLF capabilities and the narrow filters allowed me
to fine tune the MSK. My antenna was connected to the receiver-in port.
