Re: Tecsun changed design PL-390

my guess is AM/SW/LW: 1, 2, 3, 4, 6 kHz
FM: 90 and 120 kHz (wide band allows better RDS capture)
didn't read the manual, figured the old versions had this also along with de-emphasis selection.

Interesting. Had not noticed that. Based on the specs for an AM/FM chip Silicon Labs produces (Si4736/37/38/39-C40) my guess is that the seven bandwidths are 6, 4, 3, 2.5, 2, 1.8, and 1 kHz.

I see that the "60" allows for adjusting the sof mute and 7 band widths.
