Review Anytone AT-588UV

After reviewing Wouxun’s mobile transceiver, which still needed some work, all attention shifted towards the Anytone AT-588UV (now changed to AT-5888UV). I’m not the first to express my feelings about this rig, nor will I be the last. I took my time to review this mobile radio, as early reports contradict each other in almost every respect. When opinions vary from ‘Piece of junk’ to ‘Best radio ever’, I tread more carefully than usual.

First impressions
The Anytone AT-588UV is a good looking mobile rig. The front panel is detachable for mobile use. Eight direct access keys are placed just under the LCD. The readability of the typeface used to describe their function is excellent, even from a distance. Display color is highly configurable, thanks to the implemented RGB color system. An insanely loud beep, enough to scare the living daylights out of you, is heard when you switch on the radio. This can’t be changed.

The microphone connector (RJ45) is located at the right, a USB connector at the left. This connector isn’t there to program the Anytone by computer, as you might expect, but only to charge your phone, MP3 player or similar device. Programming is possible with an optional cable which has to plugged into the microphone input. At the back there are two outputs, one marked external speaker and one marked A/V. Because both accept the same 3.5mm plugs, it’s easy to make mistakes. I made a few mistakes on purpose, but not harm is done when you mess up. The antenna connector used is an old fashioned SO-239, not N.

When seen from above, this Anytone looks similar to the Alinco DR-635, up to the position of the internal speaker and cooling fan. The fan of the Anytone only kicks in when needed. Nice.

General
At first glance the supplied multi-functional microphone is one we would like to see standard on every rig, but there’s a catch. Instead of putting the up- and down buttons on top, where they belong, they’re located at the top right – exactly in the place where your thumb rests when holding the microphone. The lack of a ‘lock’ switch adds to the misery. Rumors are that new batches of the AT-588UV will be delivered with another (usable) microphone model.

The external speaker connector is unreliable. The only way to make it work is by inserting the 3.5mm plug firmly and pull it out slightly. One wrong move, one little tremble, and the audio goes dead. Probably easy to fix, but sloppy nonetheless.

Menus
The menus look very similar to the ones we know from Yaesu. Personally I don’t mind; Yaesu menus are relatively easy to work with once you understand the logic behind them. There are some options there you won’t see elsewhere. A two/five tone generator is one of them, AM detection up to 174 MHz is another. AM detection can be set to automatic or manual. The last option will allow you to listen to AM transmissions on 2 meters, not only air traffic.

Receiver
Sensitivity on both bands is fine, between -124dBm on UHF and -127dBm on VHF. I had really low expectations when I started to look at the quality of the front end. VA3ISP reported that he heard pager blasts while listening to the amateur bands, but I couldn’t replicate such problems. On the contrary, the receiver of the AT-588UV performed better than average when it came to handling unwanted and strong out-of-band signals.

Frequency range RX:
118-174 MHz (AM/FM)
220-260 MHz
350-400MHz
400-490 MHz
49-870 MHz (Optional)

RX Audio
RX audio is not very pleasant to listen to. There’s such an amount of distortion that’s is not something which is only measurable, but clearly audible. The audio amplifier also spits out a generous amount of noise, even when the volume is turned down to a minimum. On top of all this there’s an annoying high pitched tone present when the squelch opens. My frequency counter, DSO, nor spectrum analyzer were able to isolate the frequency due to the reported noise and distortion. I eventually managed to pinpoint the frequency by tuning my function generator until both tones were zero beat. I ended up at 4000Hz, give or take a few Hz.

Transmitter
My review sample suffered from a flaw which has the same effect as a broken microphone wire: sometimes your modulation is fine, sometimes it’s gone almost completely. To make sure it really wasn’t a problem with the microphone, I replaced it by another microphone which belongs to my Anytone 70MHz transceiver. The problem didn’t go away. Contrary to other reports there seems to be no relation to the input level – it doesn’t matter whether I whisper or yell. When it works, TX audio quality is great though.

The problem doesn’t impact the cross-band repeater system (which, BTW, works well.)

Power output
The Anytone AT-588UV offers four power output levels: Low, Mid2, Mid1, and High. Measurements done at 145 MHz and 435 MHz respectively are as follows:

145 MHz
Low: 4.8 Watts
Mid2: 9.2 Watts
Mid1: 29 Watts
High:  52 Watts

435 MHz
Low: 2.1 Watts
Mid2: 5.4 Watts
Mid1: 15 Watts
High: 35 Watts

Frequency range TX:
136-174MHz
400-490MHz

Harmonic suppression
Whenever you look at harmonic suppression, VHF seems to be harder to control than UHF. There is some room for improvement on VHF, but overall the Anytone does a good job.

VHF, second harmonic, 53dBm down. Room for improvement.

VHF, third harmonic, 64dBm down. Excellent.

UHF, second harmonic, 58dBm down. Good.

Conclusion
The Anytone AT-588UV is far from perfect. The rig is plagued by design flaws which all have to be sorted out by the manufacturer if they want to have any chance of impressing the ham radio world.

If I may be blunt: many flaws are impossible to live with. If I transmit, I want to be heard. If I listen, I don’t want to be annoyed by noise, distortion and high pitched tones. If this annoys a 57 years old guy who even can’t hear the complete audio spectrum anymore, I wonder how younger operators would think about this.

Then there’s build quality, which is only average. I’ve spotted coils which weren’t soldered properly, causing one end of the coil to hang one micron above PCB ground. There are PCB connectors which aren’t aligned neatly. The external speaker output is unreliable. You can’t get away with this, not even when it’s compensated by a rock bottom price.

Bottom line: good ideas, poor execution. I’m sure the manufacturer can fix the rig, but it will take time. If I would like to own a Chinese mobile radio, I’d rather put my money in an improved version of the Wouxun KG-UV920R.

  1. Well, it’s clear what to think in general of most china products that are not of the likes like Yeasu , Icom, or Kenwood, it is also good to know, so you should not pay too much, recently i bought a gsm-watch, via Dutch website, but it was ordered from china….. total crap ! waste of money :(

    • It appears so, there’s an A/V connection at the back. I’ve not been able to test this. There’s an Anytone Yahoo group active; it could be worth wile to register there and ask current owners.

  2. A distributor in the United States told me that many of the problems with the radio would be fixed with those shipped on 20 March 2013. He also stated software would be available to bring previous versions upto date. It will be interesting to see if there are changes for the better.

    • That would be great. So far the radio didn’t impress in any way, which was disappointing. Let’s see if they dare to send me another review sample… they might hate me by now ;)

  3. Hi all
    I did a video (sri for poor quality) http://www.youtube.com/watch?v=hgPF4UrSkUg
    you can see what happens, if squelsh is open volume is half and than reducing the volume till its “quiet” you see the tone has 10-15db and 4500 hz. Raising the volume and the tone doesnt affect the acoustic noise.
    The same you will hear, and after that you hear the tone is overlaying the signal of a repeater.

    • Hi Alex, what does this mean? I’m not sure I understand, I see the video, and I heard a slight “hiss” when squelch was not open. Also are you testing the latest radio that they are shipping? I was told they fixed the previous problems and reviews I am reading say the radio is a great performer, the reviews I read are from hams who have owned other dual band radios over the years and they seem to be pleased with this radio. Perhaps the bugs have been fixed in the newest release of this rig…

      • Hi Nic,
        I bought this radio CRT 270M = Anytone 5888UV = Intek 2040 at beginning of May new, so it should be the newest version. If squelsh on but volume is off the hiss is lower than if you have a weak signal < S3 , than I can not read the other station. In http://groups.yahoo.com/group/Anytone_AT-588UV/message/536 some hams returned the radio or sold it, its very annoying. I wrote to CRT http://www.crtfrance.com according this problem, no answer yet.
        In the video you see x-axis = frequency y-axis=level/db, so first squelsh open and only noise, frequency = 800hz/relative level 0db, than squelsh on,monitor on, volume off frequency = 4500hz, relative level -20db.
        If I get now answer from CRT till this week, I will return the CRT 270 to my dealer….

  4. I have the same problem with the crossband Schuel and also does not work nose if it is blocked by software proque anyone know anything about this? exite any website to update the firmware?

  5. Hi I’m looking for a duel band mobile to pair up with a Kam XL duel port TNC for packet radio. It would have to support dual simultaneous TX on both V/UHF bands + CAT control for frequency and power agility. Any idea’s? I guess this radio is not it as I don’t even see a rear data port for packet? Regards, Ken – vk4akp (@Gmail) .-.-.

  7. Hello all
    I have 3 AT-5888uv radios and love them. But now 2 have a speaker issue.
    The speaker volume is very low on the UHF side. It is fine on the VHF side. If I put UHF on the left and right the I have volume.
    any input would be great
