I had spare change to buy something for my belated birthday, so I bought this. This radio came the next day thanks to 1 day shipping, shipping was fast. I took it out of the box, and it came with a cord, and also took the D cell batteries out of an SW boombox that I hardly use. I powered it up for the first time using the cord, and set up was very easy. The AM Band (MW Band) is permanently set by default to tune from 522 kHz to 1620 kHz at 9 kHz increments. The AM reception is very clear, and I bet it will be very good too at night. To pick up distant stations you will need to use a tunable loop antenna and couple to the receiver or use a ferrite rod coupler for your active and passive antennas that is for the AM bands. Since it only tunes 9 kHz stations, you will have to enter the local / distant AM stations you want to hear and enjoy or take your time to slowly tune the tuning know at 1 kHz increments. It's a very good AM receiver to use on the bedside or anywhere day and night. The SW bands are great, and this receiver give you, the listener the ability to tune from 2.3 MHz (120 meters) to 21.195 MHz (15 meters) to hear the world such and international news, music and events, and sports. You will need to use the telescoping rod antenna for moderate the strong signals on the short wave bands, and a wire antenna indoors or outdoors for weak to moderate signals during the day and night. This radio is very easy to use, even for a beginner, and since it's digital tuning it should be much easier than using a analog dial. It does give you the ability to preset the memories as many as you need to through the ATS tuning or memory feature. I would recommend that you purchase also a reeled up wire antenna to use indoors and outdoors since there is no external antenna input jack. FM Band is great since it's able to tune from 76 MHz to 108 MHz which is likely you will hear TV NTSC channels 5 which is 81.75 MHz, and channel 6 for NTSC audio on 87.75 MHz, and also the entire FM broadcast band. If you happen to be around Japan when travelling, this radio is able to tune the local Japanese FM broadcast band from 76 MHz to 90 MHz, and the rest of the world from 88.1 MHz to 107.9 MHz. For best reception use the telescoping rod antenna and move away from noisy sources. Also you can still use a dipole antenna by clippng one lead to the telescoping rod antenna. It does have th ability to receive local and distant FM stations without the receiver overloading. The best time to listen to distant / remote FM stations is mostly during the late spring to early fall season. The Recording / Playback feature is a great addition which has the ability to use a up to a 32 GB micro card (not included, but required) to collect your local and distant radio programs and talk shows, and international short wave radio broadcasts and share your recordings with your friends and family. There is no settings required to change the bit rate or anything, so everything is set and ready to go already. It can playback MP3 and WAV files even from a USB WAV recorder that I used to plug in and tested the playback feature which most of the files on it were MP3 and WAV formatted. This radio is a very easy to use radio, and it will give someone started in short wave radio listening and eventually get prepared for bigger complex receivers with single side band and other modes, and eventually help prepare that short wave radio listener for to get on the air with a amateur radio license to talk and help support the world in need.

My little workhorse. Really good FM radio I can pick up stations I can't anywhere else on any other device. It can even pick up stuff my car radio can't pick up. As far as mp3 goes. It's not great at playing audiobooks better multiple files. So what I do is I use audacity and put all the files into one big file. And then it does fine. It'll play 32GB for sure and definitely 56GB I don't know about bigger thumb drives. As far as the SD slot goes I've never tried it. The AM radio is better than anything I've got honestly. But where I live we only have 3 a.m. stations left. I can pick up about 23 strong radio stations. And I've even been able to pick up a radio station as far as 100 miles away "at night only, and consistently" but not bad for a hundred miles away. My home stereo is part of my home theater can't even do that and it's a pioneer. The shortwave well it's fun to play with but honestly I've only ever picked up three stations and that was at night. But then again I don't speak Spanish and then the one that wasn't English was a religious station. I can get far clear far better reception in the FM band and listen to the same exact radio station they transmit on AM/FM and shortwave, or is the Europeans would call AM Midwave. As far as sound, strictly mono, Even in the headphone jack. The speaker that comes with it punches well above its weight. That speaker can fill a whole room honestly. As far as battery life goes listening to the mp3 player I've gotten about 20 hours on three d cell batteries I had about 50% volume. Listening to the AM or FM radio add about 50% volume 30 hours probably. I'll listen to the mp3 player at night playing audiobooks to help me go to sleep. Doesn't use a lot of electricity when plugged in to house power. I like it I'd get another one if I this something ever happened to this one. And I've had this one for 4 years now. I use it a lot. As far as audio formats on the SD card, I've only ever used MP3. And there you go. Would I recommend it Yes. To solid little radio. Although I would recommend getting rechargeable d cell batteries. I've got nine diesel batteries and they got me through a power blackout that lasted for 3 days.
