Many thanks to SWLing Post<\/em> contributor,\u00a0Rolf Snijder, who writes:<\/p>\n

I have made the same modification to the Tecsun PL-680, that was done [by many on the] PL-660 earlier.<\/p>\n

The PL-680 is now a great radio; I think now one of the best! I do not own a PL-660, so I cannot compare.<\/p><\/blockquote>\n

Overview of modification.<\/p><\/div>\n

For disable soft mute you can see the 2 joints and you must scratch a path on the print near the switch. (same on a PL-660)<\/p><\/blockquote>\n

Closeup of joint #1 (click to enlarge)<\/p><\/div>\n

\"\"<\/a>

Closeup of joint #2 (click to enlarge)<\/p><\/div>\n

With the tone switch [on the left side panel of radio] you can turn the muting on and off. On FM I need to set it on<\/strong> for better results, but on LW MW and SW always off<\/strong>!<\/p>\n

Frequency adjust is with the pot: adj1391 in the right corner. (for the 1 kHz off freq)<\/p><\/blockquote>\n

Many thanks for sharing this PL-680 mod, Rolf! This seems like a simple enough project and one that can be undone if you aren’t pleased with the results.<\/p>\n
