anytone at 6666 review
Dubbed to become the successor of the AT-5555, I wondered if some flaws were fixed, or about to be fixed. When I reviewed the Superstar 6900N, which I still own and use, I ran into a few problems. The most prominent one was the presence of unwanted mixer products up and down the carrier.
CRT France, apparently very annoyed by my findings, refused to send a service manual. This ruled out the possibility of finding the cause, let alone a fix.
Last flaw: 5 KHz steps are too coarse for amateur use.
The AT-6666 best 10 meter cb radio is one of many so-called export radios. An export radio is basically a CB transceiver that can’t be sold legally in most countries. Either the power output is too high, the frequency range is too wide, or some modes aren’t allowed. In most cases all of the above applies.
The trick some manufacturers use is to initially limit the frequency range to 28.000 – 29.700 MHz and advertise these radios as ham radio transceivers. Suddenly these radios are legal to sell, because ham radio operators may use any mode and generally don’t have to worry about power output restrictions.
The catch: without exception it is very easy to modify these transceivers and change them into an (illegal) CB radio.

The first thing I noticed is that this radio looks more like ham radio equipment than previous models. The ‘old’ Anytone AT-5555 and all its identical twins can be recognized as CB radios from miles away, but this model could fool you.
The AT-6666 best 10 meter cb radio is a small radio: 24.6mm x 15.7mm x 4.8mm (depth x width x height, heat sink and knobs included). The microphone is simple but ergonomic with Up and Down buttons located on top.
The LCD background color is selectable, something I like a lot.
If this is a beta version, it doesn’t show. This is a nice PCB, neatly built.
RF power is generated by four 13N10 Power MOS FETS (download specs here). Three are mounted at the back, one at the left.

Harmonics, Phase Noise and Mixer Products
Whatever Anytone did they did right: the strange, unwanted mixer products are gone, and harmonic suppression is excellent. There’s no phase noise of any importance present, which is a sign of a stable oscillator.
With a harmonic suppression better than 60 dBm, this Anytone joins the ranks of the best.
No phase noise, no unwanted mixer products.
At the highest resolution of the counter I measured a difference of +5Hz. Such a small difference is completely irrelevant.
Power Output Measurements (@ 29.000 MHz)
FM: 40 Watts
AM: 15 Watts carrier, 30 Watts @ 100% modulation
SSB: 55 Watts
Not quite at the promised levels yet. Don’t forget that this is a preview sample.
The menus are divided in two parts. One is hidden under the menu button, the other under the channel selector. The menus pop up when you press these keys for about one second.
Channel Selector Menu
- Hi Cut (on/off)
- Noise Blanker (on/off)
- Echo (on/off)
- +10 KHz (on/off)
- Roger beep (off, 1-5)
- Beep (on/off)
- Indicator (Off, SWR, Time Out Timer, DC Voltage)
- Microphone Gain (1-36)
- NOG (monitor volume, 1-32)
- TOT (Time Out Timer, Off / adjustable up to 600 seconds)
- TSR (High SWR Protection, On/Off)
- TDC (High Voltage Protection, On/Off)
- SCM (Scan Mode, SQ/Time)
- FIN (Fine Tune, RX only / TX only / Both). Adjustable with Clarifier, range ± 1.5 KHz.
- Color (LCD background color, for choices see above)
The front panel of the radio is more or less self explaining. You have an on/off/volume knob and adjustable RF power, RF Gain, Clarifier and Squelch pots. At the back we find a micro USB connector, so there’s no need to open up the radio in order to program it.
On the air
The first thing I noticed is that the quality of the modulation improved. The AT-5555 / Superstar isn’t bad, but a bit on the tinny side. This radio sounds more like my Yaesu FT-900. I could work what I heard, and in the end that’s all that counts. Sensitivity is fine and on par with the previous models.
For a beta version there are surprisingly few flaws to be found. Almost all of my gripes were addressed; the AT-6666 best 10 meter cb radio is what the AT-5555 should have been, or what I hoped it would be.
There are still a few things on my mind:
- The price is unknown, hence price/performance is unknown,
- The passive cooling is likely insufficient. The heat sink gets really hot, and does so in a short amount of time,
- Still 5 KHz steps at default on 10 meters. Smaller steps can be set by pressing the channel selector momentarily, but the radio will default to 5KHz as soon as you let go. Oh well, it’s a CB radio, right?
- I didn’t look into all the details of the programming software, but it appeared to work as advertised.
Bottom line: I like this radio. I like it a lot.

thank you for your notification.
we will correct it Immediately。
how much is the Anytone AT 6666 i see all the stuff about them never a price i want to buy one
please visit best2wayradio.com to buy the radio
Anybody know what happened to best2wayradio.com ? The website vanished early June 2017 and as of this post has not returned. Are they on extended leave or kaput? I wanted to get the CTCSS/DCS option for the AT-6666 that was on their website and now I can’t find anyone else selling this. Apparently Anytone has an option that no other dealer wants anything to do with.
it’s on stock now.
