Re: [IRCA] Tecsun PL-300WT DSP-enhanced Ultralight Radio--Amazing Performance

But not many in the industry even acknowledge the sidebands. And typically, the casual listener isn't looking for a station 10 or even 20 kHz away from their IBOC locals.

And we do need to remember that even if the radio's case looks similar, what's inside doesn't have to be.
