Retekess V-115 portable radio with all features you need: FM/AM/SW band, and also have 3 record mode, bass sound music player that can play MP3 and WMA files. You can record your favorite music or talk shows on the radio, and can record the external sounds with the built-in microphone. This Multi-Functional Radio not only allows you to enjoy the radio, but also brings you a great fun.
Of course, there is no SSB for this low price.
AM reception seems to have low sensitivity due to the obvious small size of the ferrite antenna
FM stations do pretty well on average. Listen to one of the major shortwave broadcasters with a booming signal into your part of the world you cant beat it for this price point.
The audio that comes from this little radio is awesome! Nice bass response! Strangely enough the audio via the earphone does not seem to have all that bass. No stereo either.
The recordings are very good and do have stereo of course. So listening to MP3's or recording them can be enjoyed with stereo headphones!
Mod for your Radio!!!
MOD noise [SOLVED]
Has a high background noise or hiss like interference on SW and AM. Probaly the internal circuitry (most likely the display) was causing this interference.
Second possibility could be the battery type of brand related (internal resistance of the battery).
Anyway, this problem is fixable:
Decouple the power/battery with a electrolitic capacitor of around 10uF (between 4.7...22uF will do) soldered to the battery connector (inside the radio).
I also grounded the
speaker (center pin is the chassis of the speaker)
connect a little wire from the metal housing of the speaker to the ground of the pcb (I used the position next to C22). Not sure if this is needed, but it wont hurt.
