ATS-20+ ポータブル短波ラジオ Si4732 FM AM MW SW LW SSB

My main radio setup is being rebuilt and I wanted a quick SW receiver for temporary casual use. This tiny multiband super-portable receiver turns out to have been a decent choice. I haven't tried longwave (is there any left these days?) but for casual shortwave listening, it has decent sensitivity compared to another good portable, good sound for a radio this tiny, and a USB-C power connector, so you can take it anywhere and recharge as needed. The case is gorgeous--sturdy aluminum, well made. Antenna uses a BNC connector so you can use any number of antennas with this radio. (Mine receives what I want quite well with the standard extendable antenna and another BNC antenna I have. Easy to overload on SW with too much antenna, no surprise in a battery portable.) The down sides: the control layout is fairly weird: two parallel rows of buttons front panel, a few (including the power switch) on the back panel. Very unusual and very clunky, but I got used to it quickly and the performance is more important to me. Also, each step (on SW) silences the receiver for a brief (sub-1sec) moment. So if you're trying to tune across a band, you have to stop on every step (6035, 6040, 6045, etc) to see if there's a station there. Expensive radios and analog receivers don't do this, and it is a nuisance for SW DXing, not so much if you already know what frequencies to go to. There's no way to input frequencies directly. The encoder dial does occasionally give one hiccup as others have noted; that isn't a bother to me, YMMV. jI'm not sure how long the battery lasts in heavy use, but with the USB, it's easy to power/charge. So overall, this radio is a bit clunky to use and it is not a first choice for a budding DXer, obviously,. But it is remarkably tiny, has decent performance on shortwave and FM, it's easy to charge, and it was a decent price IMO when I got mine. For me, it turned out to be a good choice for a temporary evening-listening radio. Overall,I'm entirely satisfied; the few downsides aren 't important to me, and the positives are very good. Even after my regular radio setup is rebuilt, I'll be keeping this little portable receiver for trips or use out in the yard. Thumbs up on this one!

I bought something that was similar on Amazon last week and had to send it back. The reception was horrible even with an antenna attached to it. Saw this Item and have been thinking about buying. Boy and I glad I did. I have 2 to-sdr blog v 3 hooked up with a 9:1 Balum. Connected to a long wire antenna. Been listing to hf, ham, Le and shortwave frequencies. But was looking for something that was portable. Without ever having to connect a long wire antenna to this device, it has been picking up in our home the same things that my outside long wire antenna has been picking up. The FM reception inside is not the best but will come it. I’m very pleased this device can pick up these frequencies. I would totally recommend this. The included antenna is doing just fine. I’m thinking if getting a BNC adapter to connect my outside antenna up to this and see what it can really do. Do yourself a huge favor and buy this. It’s amazing for the price.

This is disappointing. The receiver case is very nice, compact, solid, metal. Some of the front and rear panels edges are a bit sharp however, a failure to deburr after cutting. The display is bright and easily read. The FM band receives many stations and sound is surprisingly crisp and good fidelity for the small case and speaker. However, it's a radio, and reception is most important. I fully extended the whip antenna, and changed its orientation when testing. AM band is extremely poor. In the Washington DC area there are many AM stations, and at night even car and moderate cost portable radios get Baltimore and NYC, and maybe Boston. This got 6 in the local area at night. SW is worse. Manually scanning all bands in AM, LSB, USB I picked up only a couple weak stations. I didn't try a long wire antenna, which may improve performance, because the radio is a "portable", and I have others that work well with just the whip. "Automatically" finding stations worked only for FM. It jumps to the next usable station, not a scan, pause, proceed type scan I will be returning it.

Solid little radio. When it arrived earlier this morning I placed the charger on it. It started popping (not static but popping) through the built in speakers. I power cycled it, and trouble shot it before I decided I have nothing to loose and opened it up (uses open source flashing which is not the culprit here). On manufacturing the battery was punctured. Electrolytic oil was all over the underside of the pcb board and the bottom of the chassis. So heing the impateint person I am, instead of contacting the manufacturer for a replacement, I cleaned everything up, removed all corosion from the solder points, and found a replacement battery I had luing around from an older project I did. Once cleaned, and a fresh battery was connected it fired up and is working no problems. I do not recommend doing what I did unless you know what you are doing, but in my case I rolled the dice and seemingly got lucky. Due to being sent a faulty peice of technology that required about an hour of my time to disconnect, clean, and rewire a battery to use I deducted 1 star. I don't mind building and fixing equipment, but I bought it brand new. If i reached out I am sure the shipper would have issued a refund or an exchange but it works, has an upgraded battery, and honestly is kinda really cool. Go through the appropriate channels and don't do what I did unless you know what your doing. Great little radio dispite this issue! Already gotten a lot of signals around FM/AM/SSB/SW.

Radio works. It is a neat radio. The arduino, on my unit, is unable to to accept new firmware download.
