From my QTH in Northern California, I spent time monitoring the 22 m band Typically ~18:00 UTC each day.
Logged using Spectrum Lab on the pc, connected to the receiver's audio line output, I detected NC (13,555.6~), USC (13,555.5) and MTI (13,557,530). in the The former two use narrow FSK modes, all three operate at QRSS speeds.
During a later 12 March session (23:00Z) NC was audible as well as a strng trace via spectrum lab.
Conditions did not favour the commonly heard AZ, AA0RQ or GNK this time around.
