Much weaker than usual Spanish language traffic on 6900 USB this morning with very heavy QSB. Hearing one OM talk locally, checked a couple remote receivers and signal is better further in-land (the midwest US SDRs hearing the QSO much better than east coast US SDRs - and I'm on the east coast so that makes sense).
Similar to the many other logs I've made on 6900 kHz LSB and 6900 kHz USB. I have a feeling these are some of the operators who use the mode switch as a way to escape QRM.
