Several of us out west, some near Portland and others south in central Oregon are hearing canadian hams in the prefix contest operating on SSB below 28.300MHz.
CF3A is on 28.298 USB running stations and VE3EJ is on 29.289 USB.
We also hear them on 2 of the online SDR receivers, did Canada expand their 10 meter phone band to go into the 10 meter beacon band?
