Hearing weak Morse code using USB with my Sony ICF-2010 on 257 kHz with the internal antenna. I do not know Morse code but “LW” in Kelowna, British Columbia, Canada is the nearest beacon on 257 kHz and also higher powered than most stations on the frequency according to this list:

Also hearing what is probably “DC” on 326 kHz USB from Princeton, British Columbia, Canada. Same pattern of a Morse code identification followed by a tone then identification again.
Also hearing what is probably “SX” on 368 kHz USB from Cranbrook, British Columbia, Canada. Same pattern of a Morse code identification followed by a tone then identification again.
Also hearing what is probably “YWB” on 389 kHz USB from Kelowna, British Columbia, Canada. Same pattern of a Morse code identification followed by a tone then identification again.
