Question: I received my radio and do not understand how to use the usb or sd slots, what are they for?
Document: I just received this radio tonight and have been trying it out. I'm totally jazzed! I took a chance and bought it to use in my workshop while I'm doing woodworking. Everything about it works better than I expected, especially given the modest price. So far, I've listened to AM and FM. Reception seems pretty good. I haven't experimented with the short wave functions yet. However, I've used the SD card and USB functions and they work well.
For all the bells and whistles this thing touts in the description, it's unacceptable that the antenna - a function of AM/FM radios for the past 100 years - could suffer from such a glaring oversight. Regardless of whether or not the manufacturer replaces the piece (it looks like it can be replaced), I shouldn't have to replace a piece of a radio I received only 1 day ago. Can't say I'd recommend this one.
Not noticeable when on, but when off, you can hear it in a quiet room or when you put your ear to the speaker. I unplug the radio when not in use. The power cord is the cheapest I have ever seen. The weight of the unit is not much and I cannot imagine it surviving a fall of any sort.I don't feel the need to return the radio but I would not buy it again or recommend it to you.
I really like the way you have a choice of using a recorded  SDcard or even a better option was the use of the thumbdrive seeing that I can load all of my music on it and don't have to be concerned with radio Ads. The short bands however are basically worthless! The Am/Fm radio dial is very sensitive, and some stations I prefer are hard to locate, also the dial it kind of glitchy, herky jerky may be a better term!
This is a pretty cool little radio with some bonuses for the price I paid. BUT, anyone you gets one should be aware that you shouldn't use it in direct sunlight as the thin plastic tuning guide ... the piece that shows the frequency selection inside of the dial, on mine melted. So, I would be okay tuning by ear for what I want except that the melted plastic piece interferes with the tuning. This was so inexpensive that I'm not likely to return it.
Bought this mainly to use in the garage, but I find myself using when I go camping and fishing.
Double humped response on FM - tune across the station, then a null, then the station again. AM broadcast band good. Short wave very insensitive. the few SW stations received above about 8 MHz had a strong image - the station was received at two places on the dial, 910 kHz apart. Plenty of volume and good sound.
For the price, this is a great product. Be warned, there is VERY little bass, but really bad bass is worse than little to no bass. The radio reception is okay for FM, not so hot for AM, but it does work. The AUX jack is great; and the battery life is phenomenal. Truly. We can use this for sometimes days at a time without plugging it in!
Nice look but falls short in performance. The sound and depth on FM or AM are fine. The FM sound is actually surprisingly good. I did not expect much nor did I buy it for alot of FM use but I was satisfied with the sound. The main issue is the less than decent reception and the constant hum that emits from the speaker while the unit is off.I Iive 30 miles out of Chicago and still have to tinker a bit to get my stations in.
It don't have that good of receive on short wave reception. will use it now and then in the summer
Answer: I used the SD slot. Card pushes in upside down. Select SD red light comes on ,music plays..I don't like the fact that it always starts from the first song not where I stopped it
