Default Tecsun DR-920 stinks at FM

I bought a Tecsun DR-920 from an eBay seller for just under $30. I
liked the clarity of FM reception but the selectivity is really bad.
From my notes:

* A station on 104.5 MHz was heard on 104.3 - 105.7 MHz.
* A station on 96.5 MHZ was also heard on 94.7 and 91.1 MHz.
* A station on 98.1 MHz was heard on 95.5 MHz.


I'm not surprised, for that price. What you are experiencing DXers
might call overload or spurious signals. Selectivity refers to the
ability of am FM radio to separate stations only +or- 200 kHz from each
other (adjacent channel) or separating stations +or- 400 kHz is called
alternate channel selectivity or rejection. Most FM radios have poor
adjacent channel selectivity.

For your situation you might try pushing the antenna down partway & see
if that clears things up. Also, rotate antenna & see if one direction
takes out some of the overload. Otherwise for better FM reception you
may need a better radio. I don't know how close you are to your local
FM stations towers. If you're really close, almost every radio may have
problems. You might want to try the Eton E100 pocket radio, someone
said it could get distant FM near strong locals & they sometimes sell
on eBay for only $20-30. George (MN)
