Once again, I ventured out to my truck tailgate to make a few videos of the Tecsun PL-880. In this video, I’ve tuned the PL-880 and PL-660 to Deutsche Welle’s English language service on 9,800 kHz (transmitted from Kigali, Rwanda, some 7,600 miles away).
I made this video with my iPhone, so apologies for the low quality:
Note that when I first turn on the PL-660 it is in sync mode by accident. After changing the bandwidth on the PL-660, I then turn off sync.
I’ve noted that the PL-660’s sync detector locks better than that of the PL-880. However, using the PL-880’s SSB mode to zero-beat the AM carrier (see article on ECR), produces great (and stable) results.
Sensitivity-wise, these radios are quite similar. While I personally prefer the audio of the PL-880, the PL-660 makes vocals pop out of the noise a bit better.
