[19 January 2016: Please read this updated post.]

In response to Pawel’s post about a tuning bug affecting a recent batch of Tecsun PL-880s, SWLing Post contributor Georges (F6DFZ) comments:

I have posted a new video about this important bug of the PL-880.

I did so because it seems some people don’t understand this very important issue.

This video shows the Tecsun PL-880 tuning bug which is present on SSB when using the Fine Tuning knob.

The PL-880 is tuned to the Shannon Volmet on 5,505 MHz USB.

At the beginning, I use the coarse Tuning knob to shows the effect of tuning 1 kHz down ; the pitch of the voice increases as we are on USB.

Then, I tune down 1 kHz using the Fine Tuning knob, and now the pitch of the voice decreases, indicating the bug with the reverse tuning using the Fine Tuning knob on SSB.

At the end, I use the coarse Tuning knob to hear the voice with a normal pitch, and you can see that the displayed frequency is 5,503.01 MHz, a difference of nearly 2 kHz versus the true frequency.

Best regards, and a Happy New Year
