On 6666.6 USB a station keeps repeating "40" over and over again.  2302 UTC, a different station replies to the 40 station. 

6670 USB also active with Spanish language chatter.  45 meter freebanders, 6.6 MHz EC Echo Charlie out banders out of Latin America.

Based on the number configuration , I'm thinking it's a direct line to Hell!

There can be a lot of activity on 6666.6 if you park on it and listen at the right times.

Anything from peskies to freebanders to just plain odd transmissions that defy explanation. I've heard someone groaning for hours there a few years ago.

'Transmissions that defy explanation' One of my favorite types!

Indeed.  The "40" over and over again station was kind of odd.  But 6666.6 kHz USB is sort of a home channel for the 45 metros / 45 meters crowd, sort of like 6900 kHz LSB is the home channel or calling channel for the 43m freebanders and 6925 kHz LSB is the home channel (among others) for the Portuguese speaking guys.

Using the 6525 kHz - 6765 kHz range for two-way bootleg HF SSB chatter seems sort of silly to me.  There are generally plenty of clear frequencies in the 6200 kHz - 6525 kHz 6 MHz HF marine band and of course the 6765 kHz - 7000 kHz fixed/mobile band, even when the peskies are booming in from South America...will have some clear channels.   So why use the aeronautical band?
