Si4732 ATS-20+ ポータブル短波ラジオレシーバー、GOOZEEZOO FM AM (MW SW) LW SSB (LSB USB) フルバンドラジオレシーバー、ビッグスピーカー&最高の受信。

I’ve bought plenty of budget gadgets over the years, but this one takes the crown for worst execution imaginable. Straight out of the box, the ATS-20+ blasts a constant “TTTTTTTTTTTTTTTTTTTTT” noise like a swarm of robotic hornets trapped in a soda can. Every band, every setting, same ear-piercing digital screech. The audio is brittle, the tuning drifts like it’s guessing, and the build quality feels like it was assembled during an earthquake. I even tried different power supplies, antennas, filters nothing helped. This isn’t a bad unit; it’s a bad design. I’m not wasting gas money to return it. I’ll just gut it and use it as a learning project, because at least the circuit board might teach me something. Still, it’s disappointing that something sold as a “receiver” can barely receive without sounding like a dying modem from 1995. If the seller actually stands behind their product, they should replace this immediately because this one’s closer to a torture device than a radio. The item does not match the description. The listing shows an ATS-20+ with the proper STM32-based board and firmware, but the unit I received uses completely different internal electronics (ATmega328/CH340) and does not support the advertised features. The USB download port does not function as described and the product does not match the specifications on the page.

Seems to work okay but as usual it was delayed Amazon couldn't get something from their Warehouse to my house that's 45 minutes away if they're life depended on it. I averaged two or three delays a month from them After having this unit for a while I found one major flaw it has no squelch you cannot squelch out static in between talking or searching for activity. it's constantly producing noise if they would put a squelch in it it would be so much better. Why in the world that did not put a squelch on it I will never understand.

I just got this radio today so this review is just a brief outline, I will update this and a couple weeks. I realized I don't own a radio other than the one in my car, this little radio has shortwave and that was something I wanted to explore. The radio is small, I have a quarter sitting on the dial of the radio in the picture to show scale. FM comes in clear, AM is a wash so far, but that is location and antenna I am sure. the build is good.

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!

Well made, light small and portable. Covers the broad high frequency spectrum. Cw, sideband, FM the stick antenna is removable for bnc/coax antenna lead. Includes speaker headphones jack. Battery rechargable or USB powered. Along side a QRP transmitter would be a fun licensed CW ham rig. Or just shortwave listening. YT reviews helpful.
