[ICOM] Icom 781 vs. 756 Pro 3

[Fern Rivard]

Hi Jim:
    Yes, this may be due to a non symmetrical filter but that can easily 
be corrected with re-alignment of both carrier oscillators for usb and 
lsb. There's probably nothing wrong with your ssb filter but rather that 
those two oscillators have to be aligned properly.
    Cheers from Fern  VE7GZ
