Title: UNID 6928 LSB 0220+ UTC 16 March 2017
Post by: R4002 on March 16, 2017, 0223 UTC
6925 kHz LSB is extremely loud tonight, and is splattering over to the other side band pretty often.  However, I am able to copy a QSO in what sounds like Spanish on 6928 kHz LSB, with heavy QRM from 6925 kHz LSB.  6928 LSB is weaker, but there is certainly a QSO there.  This is an interesting example of the "peskies" using 3 kHz steps instead of their usual 5 kHz steps.

S2-S3 signal levels.  Just above noise floor with very heavy QRM from 6925 LSB and 6930 LSB.

3Khz steps might be the norm if the bandwidth of the TX is observed on the FFT at 2.5Khz.
this would make sense to have 3Khz steps assuming their TX & RX bandwidth is 2.5Khz.
ive always wondered what theyre saying though, i hear these "peskies" all the time.

Checking my SDR recording, I noticed a QSO on 6928 USB around 0657z. Possibly Spanish or Portuguese.

I've noticed that a lot of the time there will be both USB and LSB traffic on the same frequency.  As TheRelayStation mentioned, assuming b/w is within reasonable limits, this entirely possible (as is 3 kHz steps vs. 5 kHz steps).  6900 kHz is a great example.  I've logged 6900 LSB and 6900 USB at the same time many many times. 

The other obvious example is 6925 kHz ;)
