I often hear CW on 6759 kHz at random times throughout the day and evening.

The intercept is usually in this format:

VVV VVV VVV  NR ##  ## ## ## ##  XXX XXX AR

where ## is a two digit number and XXX is a three letter group.

There are often 3 or 4 stations on the frequency, all sending with straight keys: when one station sends the "NR" and "##",  the others will often acknowledge. I never hear anything that resembles a callsign.

One op is pretty good with a straight key; the others are horrid.

The last intercept was this morning:
"VVV VVV VVV NR 94 94 94 9 4 DAG DAG DAG AR"

Yesterday:
"VVV VVV VVV NR 84  NR 84  NR 84 DWE DWE DWE AR"
Any information on this network of straight key operators and what they're doing?

In the cold war days they were called numbers stations.  Spies who relied on HF would meet at certain times on certain frequencies and send coded messages.  They uses voice and CW.  Even today this is much harder to track and intercept than satellite phones or the internet.

It could also be the drug cartels sending coded messages to let others know when a shipment would arrive and where.

The possibilities are endless and interesting.

You can here theses number stations up around 14.078 and higher now and then, these guys obviously like to move around. As AD4U states "the possibilities are endless" although I do know this is popular with some of the Prepper crowd. Basic mobile stealth/clandestine comms without the need for tin foil hat.
