Look no further , however Must know something about short wave radio & picking up a signal, like a long piece of wire or an rf amp, a loop, That said; I have 3 radios the oldest a DX-390 from radio shack (35 years and it still shines from time to time) im in this for the fun. I was an electrical engineer once upon a time. I have confirmed contacts from below the line. Listening. Long before internet. Im of the belief that even the highest authority in electromagnetic radiation is not infallible in fact properly suspect. Radio waves do things. ( im just sayin’) so results vary.Pros : once familiarized with the interface ( how to use the thing) its quite fun to use., after 2 radios and many years its nice to be able to grab a signal and make it dance till its the best it can be instead of a fighting to find the buttons you need. Now, does it pick up anything? No such radio will perform at its best or at least adequately without an external antenna of some kind. A piece of wire will work. But Just not all the time., so get or make an antenna. Play. Not in electrical storms. Its pretty much the antenna and where in the world it is. In radio waves interesting things happen. Sometimes repeatable more likely not when youre listening to the other side of the world and its clear and stable. And you dont need a license to listen. So , i have an active loop placed 15 feet from my home and about 13 feet up with the loop oriented east-west. Had to pick some direction. (I also have a long wire terminated in a 9:1 balun . For ground Im running thru a gas discharge tube ( amazon-) to ground just to be safe. It will shut the juice from a solid lightening strike to a 4 foot pipe in the ground. Overkill really. Ill play with it. The radio picks up am band very well. High sensitivity but an elevated noise bed. Turning my loop antenna can null noise but it’s problematic the way ive built it. I anticipate many hours of fun in the band late night. I look forward to catching the Yankee ? bb games out of new york city, a lot of triple A games in surrounding cities. Gets me plugged in. I used to get them in Ohio. Now, Im in a suburban environment in central New York. FM was fun. I haven’t started to FM Dxing but i think this will be a good start. I pulled the whip out and i was startled by the sensitivity. I was in the kitchen with a cup of coffee and getting clear stations one after the other. In “setup”’ i entered my wifi code to get the radio receiving info like time and propagation data. It will glow colors on the extreme left of display indicating whether propagation is poor, ok, or good. Cool. I played for hours. So every minute i spend with it decreases its cost per usage. Lol. a good purchase.Cons; Just awkward, changing the volume requires 2 digital pen taps and a knob turn. The supplied telescopic antenna terminated in a bnc connector is loose and it appears thats the way of it. Not a huge deal. I have it used for the active antenna. I suppose ill find more but if it takes that long to find them its a great learning curve. I also have the earphone jack running to a small pre- amp ( match impedance) to a 20 watt amp and search and listening is completely transformed. I am pleased with thus purchase.

I've had more fun with this thing in the last couple of weeks than just about any other piece of radio equipment I've ever purchased. It works very well and has exceeded my expectations. I've listened to everything from amateur radio operators on 40m SSB, Maritime WX info beacons, decoded Morse code on CW and so much more. If you are a shortwave broadcast enthusiast like me, you won't be disappointed there either. I've pulled in many stations from around the world with the ATS 25 Max. Out of the box with the stock telescopic antenna, I was up and listening right away. I added an MLA 30 active loop antenna, also purchased here on Amazon, and it was a game changer as far as reception and lowered noise floor. It is currently mounted about 11 feet high on what used to be the mast for a sattelite TV dish. I live in an area with a strong local MW am radio station. I added a cheap little filter, again purchased right here on Amazon, and that cleaned up all the splatter. Now I just enjoy scanning all the frequencies and receiving modes this radio has to offer. As a guy who grew up in the 70s and early 80s, heavily in to CB radio, this piece of technology really blows me away as far as everything it can do for honestly, not a lot of money.

This receiver is based upon the si4732 chip. It has a long-lasting battery, a well-organized touchscreen interface and a quality audio system. The receiver includes a WiFi client programed to adjust the receiver's time-of-day clock and to download and display information regarding shortwave propagation conditions at your location and time-of-day.The receiver comes with a stylus for the touchscreen; you can also just use a fingertip.Upon power-on, the receiver checks the home site for updates and pops up a notification. This is a bit of an annoyance, as there's little to no support indicating *how* to get the update. (I wouldn't be inclined to update the firmware, regardless.)Broadcast-band FM reception is quite good. Shortwave reception is adequate.Edited to add: The audio at the headphone/line output jack crackles on program peaks; this is not apparent when listening through the built-in speaker.

Caro para lo que ofrece, parece un proyecto de una escuela de electrónica.Por el mismo precio se puede comprar un aparato mucho mejor.
