Contrary to other reports there seems to be no relation to the input level – it doesn’t matter whether I whisper or yell. 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. 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.
I ended up at 4000Hz, give or take a few Hz.
#Anytone at 588 vhf manual generator#
I eventually managed to pinpoint the frequency by tuning my function generator until both tones were zero beat. My frequency counter, DSO, nor spectrum analyzer were able to isolate the frequency due to the reported noise and distortion. On top of all this there’s an annoying high pitched tone present when the squelch opens.
The audio amplifier also spits out a generous amount of noise, even when the volume is turned down to a minimum. There’s such an amount of distortion that’s is not something which is only measurable, but clearly audible. RX audio is not very pleasant to listen to. 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. VA3ISP reported that he heard pager blasts while listening to the amateur bands, but I couldn’t replicate such problems. I had really low expectations when I started to look at the quality of the front end. Sensitivity on both bands is fine, between -124dBm on UHF and -127dBm on VHF. The last option will allow you to listen to AM transmissions on 2 meters, not only air traffic. AM detection can be set to automatic or manual. A two/five tone generator is one of them, AM detection up to 174 MHz is another. There are some options there you won’t see elsewhere. Personally I don’t mind Yaesu menus are relatively easy to work with once you understand the logic behind them. The menus look very similar to the ones we know from Yaesu. Probably easy to fix, but sloppy nonetheless. One wrong move, one little tremble, and the audio goes dead. The only way to make it work is by inserting the 3.5mm plug firmly and pull it out slightly. The external speaker connector is unreliable. Rumors are that new batches of the AT-588UV will be delivered with another (usable) microphone model. The lack of a ‘lock’ switch adds to the misery. 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. Nice.Īt first glance the supplied multi-functional microphone is one we would like to see standard on every rig, but there’s a catch. The fan of the Anytone only kicks in when needed. 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 antenna connector used is an old fashioned SO-239, not N. I made a few mistakes on purpose, but not harm is done when you mess up. Because both accept the same 3.5mm plugs, it’s easy to make mistakes. At the back there are two outputs, one marked external speaker and one marked A/V. Programming is possible with an optional cable which has to plugged into the microphone input. 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. The microphone connector (RJ45) is located at the right, a USB connector at the left. An insanely loud beep, enough to scare the living daylights out of you, is heard when you switch on the radio.
Display color is highly configurable, thanks to the implemented RGB color system. The readability of the typeface used to describe their function is excellent, even from a distance. Eight direct access keys are placed just under the LCD. The front panel is detachable for mobile use. The Anytone AT-588UV is a good looking mobile rig. When opinions vary from ‘Piece of junk’ to ‘Best radio ever’, I tread more carefully than usual. I took my time to review this mobile radio, as early reports contradict each other in almost every respect. I’m not the first to express my feelings about this rig, nor will I be the last. After reviewing Wouxun’s mobile transceiver, which still needed some work, all attention shifted towards the Anytone AT-588UV (now changed to AT-5888UV).
