Here’s the symptom: when you tune your brand new PL-880 to a relatively weak station on AM or shortwave, the audio level jumps from low to high in what seems like a random pattern. It’s very annoying. Like me, many assume they have received a faulty unit–some have even sent their new PL-880 back for refund.
In reality, the PL-880 is simply following a default muting threshold level and the audio is responding accordingly. Fortunately, there’s an easy fix for this–you won’t find it in your owner’s manual, but you will find it in one of the first PL-880 posts I published:
I hope Tecsun will start shipping their PL-880s with the threshold set to “00” or off. It would certainly lead to less confusion and frustration.
