Hearing US based stations working DX on 27.465 MHz LSB while truckers chat to each other on 27.465 MHz AM. Seems like the truckers are close to each other and probably have their squelch turned up. At 1513 I heard "yeah they're gonna wave something at you out the window if you hit the brake like that" and more obvious trucking related talk at 1514 with considerably stronger SSB traffic on 27.465 MHz LSB
If these truckers operating outside the CB band do have their squelch circuits turned up, they probably don't even hear the guys on 27465 LSB.
Lots of other nearby frequencies suddenly coming alive this late Friday morning.
