Many thanks to SWLing Post<\/em> reader, Gary (WN9U) who writes:<\/p>\n

Just an FYI comment about the narrow filters NOT staying on while tuning.\u00a0I read about the similar problem that you encountered during the initial\u00a0testing of the PL-880.<\/em><\/p>\n

While tuning CW stations with the 500 Hz filter turned on (fast or fine\u00a0tuning), the filter would always revert back to the 3.0 wider setting. It\u00a0had never done this before. I tried several resets with no cure. <\/em><\/p>\n

After\u00a0further testing I found the fix: I had turned on the Hidden Menu Noise\u00a0Reduction (switch 6)<\/a> and did not realize it was on. <\/em><\/p>\n

After turning off the\u00a0Noise Reduction, I was able to tune with the narrow filters set at any\u00a0band width. Evidently, the filter opens up to 3.0 when tuning with the\u00a0Noise Reduction turned on & reset does not turn off this function.<\/em><\/p>\n

Thanks so much for the tip, Gary! I’ll add this to our (still) growing list of PL-880 hidden features and tips<\/a>. Seems there’s always something to discover on the Tecsun PL-880.<\/p>\n","protected":false},"excerpt":{"rendered":"
