Re: Tecsun Pl-310ET vs Pl-380

AM performance for portables in general is heavily determined by the size / length of the internal ferrite antenna, which can be improved by any number of options.

Hi,
I'm
sure others will respond, but I think there is a comparison
document between the PL606, Pl-310 and PL380 written by Gary
DeBock somewhere on the net. It might even be in the
Ultralight file area.I think the main conclusion
was that the PL310 has a longer ferrite rod antenna than the
380, so the 310 has better AM sensitivity. I own a PL606 and
PL310 here and there is not much between them, although
moving from one end of the band to the other on the PL606
can be a pain with the thumb wheel tuning.I have
not been that impressed with either due to spurii or
"birdies" in the bands. For instance, on 882 kHz
in the UK there is a "whistle" on both that
obliterates BBC Radio Wales, which is about 250-300 miles
from here. Others have reported other "birdies"in
the band. I don't find either of them that sensitive on
AM with the stock antenna. With headphones on there is also
a big gap between the lowest usable volume setting (05) and
the next one up (06). A bit annoying when using them in bed.
Not bad radios, but they have their
irritations.My Degen 1103 (which is not classed
as an ultralight) knocks spots off both on AM
sensitivity. Regards, Steve
