6660 kHz LSB vs. 6656 kHz USB [Via G8JNJ SDR] 1855 UTC 9 February 2026
« on: February 09, 2026, 1857 UTC »
Receiver: Wessex SDR receiver, located in South West UK.  Grid square IO80QR.

Frequency:  6.660 MHz 6,660.0 MHz 6660.0 kHz LSB.   Tune in time:  1853 UTC / 1853 local.   

Activity on 6656 kHz USB 6.656 MHz USB also noted, it does not appear to be aeronautical traffic, 6655 kHz USB is an aero frequency 6.655 MHz USB.

The stations on 6656 kHz USB appear to be Portuguese speaking, the guys on 6660 kHz LSB are French speaking and are considerably stronger, signal strength peaks at S9+10db, but most signals in the S6-S7 ballpark, very readable either way.  Severe QRM due to the overlapping signals and use of lower side band vs. upper side band making listening very difficult.
