In the following video, I compare single side band reception between the Tecsun PL-880 and PL-660. On 80 meters, in SSB mode, you can hear that the PL-660 has a slightly lower noise floor than the PL-880.  Note again, however, that I mistakenly had the tone control of the PL-880 set to “bass.” I’ll try to make another video later with the tone control set to the “treble” position.
