[Elecraft] K3S ELF 10KHz

[Doug Smith]

Yup.  Earlier in the thread Mike / KK5F pointed that out.  He was on the RX end of the circuit.

We monitored stations from Perth, somewhere in the UK, east coast of USA, west coast of USA, etc. etc.  Must have been six or eight stations on the air.  We also monitored WWVB but I think that was the highest frequency (60 kHz) we cared about.

It was all RTTY as I recall.  We didn’t bother trying to decode the stuff — it was encrypted and we didn’t care about the content.  We only cared about signal strength.  Fun times; long time ago..
