[ARC5] NLK, Jim Creek near Oso WA

[Richard Knoppow]

    I have the same memory. NPG, on HF, identified as VVV NPG F F F and 
later as NPG/NLK VVV VVV VVV Not sure if the F was still sent. Lots of 
30WPM five letter code groups. I used to tape record the transmissions 
and play them back half-speed as practice material. I did have a VLF 
receiver of sorts, actually a General Radio hetrodyne detector from a 
frequency measuring system. A simple regenerative receiver with plug-in 
coils. Listened to 500KHZ on it. I don't remember hearing NPG although 
they probably put in a strong signal on some LF.
