In the following video, I have tuned both the Tecsun PL-880 and the PL-660 to a relatively local AM station (880 kHz). Note that I had the tone control switch set to “bass” on the PL-880 (it would have been better on “treble”):
For normal AM radio listening, I believe the PL-880 produces better audio fidelity than the PL-660. I will try to record a weak medium wave station this evening, if time allows.
