LSB to USB ?
 

Hi,

Technical question requested by a ham:

Is it possible to receive an image signal on a low frequency on USB mode and
find the true signal at some higher frequency in LSB (e.g. 6.1 mhz usb and 7
mhz cw-lsb). It seems that some UA stations emitting on 40m have their image
on 6 (e.g. 7043 - 6135 = 907 / 2 = well IF 454 khz) but a reversed mode ...
?? Looks really strange if not impossible.
