Anytone Smart CB (a.k.a. Albrecht AE-6110, CRT ONE)

First, I want to say thank you to Simon The Wizard for his BLOG Posts on this radio, which convinced me to give one of these a try.

The Anytone Smart CB has got to be the most interesting little critter to hit the market in years: Sure, it doesn’t have SSB, and it is only 4 or 8 watts of Carrier, but come on, it is SMALL. Normally, a radio without SSB doesn’t even get my interest, but what the hell…

I ordered a pair of these radios, one for me, and one for a friend that wants to get into the radio hobby without breaking the bank. Here they are, fresh off the Brown Truck… (For Reference, the Knife’s total length is about 7 1/2″)

01 Boxes

Lets take a look at these little critter and see what it is all about:

Size: This little radio is just that… LITTLE. Not counting the Hardwired Mic, the radio 4” Wide, 4.25” Deep and about 7/8” tall.

02 Little Radio

They come as a 10 Meter Radio, so there is a bit of tweaking to get them on the 11 meter band… or 25.615-30.105 Band, if you plan to run on 11/10 meters (Or anywhere above, below, or in between), so you will need to pop the lid to do the mod. It Takes a soldering iron, solder, and a little bravery not to fear the dreaded world of SMT (Suface Mount Technology)

To Pop the lid take a really small Torx tip (T7?), or a precision filed flat head screwdriver… 😉 but once to get it off (mind the short speaker lead the plugs into the circuit board) you will see something like this:

03 Guts

The Power comes from a 13N10  QFET MOSFET (Upper Left Corner)

But what are all the rest of these little things? What do they do? What does it all mean?

Calm down, the only thinks of major importance to the normal operator are these:

03 Guts ADJ

So First things first: Get it on the band you want: Look at the MODE SELECT portion of teh board…

It Comes  with: OP2 Soldered, OP1 Open (10 Meter Amateur Radio Band Only)

Here is what the OP1/OP2 jumpers get you in their given Configurations:

OP2 SOLDERED, OP1 OPEN

10M

OP2 OPEN, OP1 OPEN

11M

OP2 OPEN, OP1 SOLDERED

Freeband

I’m willing to bet where 99.999% of anyone that reads this Blog will set this radio up…. but I digress….

Warm up the soldering iron and follow your heart…. Mine ended up like this (the Flux was cleaned up after the photo was taken…):

05 Guts 2

Enough said about that…. So Lets see what it will do from the factory.

The Set up was: Power Supply, Anytone Smart CB, Diamond Antenna SX-600, Dummy Load, and Rigol DS1102E 100 MHz Dual Channel Digital Oscilloscope.

First I checked the carrier in AM in LOW POWER Mode (on the 5 Watt MAX Scale):

06 AM Carrier

I checked the FM Carrier as well On Low Power:

07 FM

Then I switched back to AM, still on LOW POWER, and modulated it using a 1 kHz Signal into the mic element.

Carrier on the O’Scope:

14 LP Carrier x10

Giving it a bit o’ modulation:

10 Modulated

Looking good indeed!

You may ask…

“How much “SWING” did ya get?!?!??!”

My Answer:

Who Cares. I don’t look for “SWING”, I look for Modulation Envelope. I want to see 100% Modulation with no over modulation on the negative peak, and no Flat Tops on the Positive Peaks.

So lets try the HIGH Power Setting; Hold onto your hats fellers, that mean 8 lip cutting watts of carrier! So here we go:

Meter (We are on the 20 Watt Max Scale now):

12 High Power Carrier

And on the Scope:

11 High Power Carrier

Give it some Modulation and….

13 High Power Modulated

Ahhh, WTF?

Yup, that was the most modulation I could get out of it….

That ain’t 100% Negative, and starting to Flt Top The Positive Peaks…

Interesting…

There isn’t enough audio Power to Modulated the High Power Carrier… very similar to the Stryker SR-655HPC at full power… but that is a story for another time…

Interesting to note: if you crank up the Modulation adjustment too far, it just quits modulating. On LOW POWER, this thing will do 100% negative peak, they it stops modulating, until you turn it back down… On High Power, this is all she’s got…

So I decided to check the FM Deviation; now I don’t have the Cool FM setup equipment, so I did it the old School way: turn on a receiver radio and give it a listen:

I notice that the audio was low on the receiver side, so I turned up the FM Deviation variable about 1/4 turn and the audio came right up. I turned it a bit more, the the RX Audio became distorted, so I turn it back down until I had a strong, distortion free audio signal on the RX Side.

When I got it setup, I decided to see what the Audio bandwidth looked like.. you know, because I’m an Audio kinda guy…

As the few people that read this Blog probably know, my ICOM IC-718 isn’t stock. it will Transmit 40Hz to 6kHz in AM Mode (40Hz to 3.3kHz in SSB), and Receive 40Hz to 6kHz in AM (40Hz to 6kHz in SSB as well).

I first did a 40Hz to 5kHz audio sweep (using the signal Generator feeding the Mic on the Anytone) and received it on the ICOM. Then I  Transmitted on the ICOM and received it on the Anytone and got this:

YELLOW Line is the TX Audio received on the ICOM

BLUE Line is the RX Audio transmitted from the ICOM

TX and RX Sweep

Interesting pattern to say the least, but I can tell you in real world test, this thing has some serious DX’er quality Audio. No Low end… I believe that bump in the YELLOW line is an odd artifact, because on air, it sounds more like the BLUE line with a 250Hz roll off…

Here is what the On Air Audio sounds like as recorded by my SDR Dongle using SDR#:

 

If someone can get me a schematic of this puppy, I think it it could be increased in the audio bandwidth department, it ain’t gots no stupid Modulation transformers that I have located yet…

Final Thoughts?

-$70 from Amazon

-Small enough to hide in your tighty whitey shorts, or stick almost ANYWHERE in a modern vehicle

-Best bargain AM Radio out there on the Market… and you Get FM Mode!

-She does get warm, and down right Hot if you are long winded (or do some long testing with it)

All in All:

16 Little Package

A Lot of radio in a VERY Small package

    You are about the only definitive source I can find that is based in the USA on this radio. There seems to be alot of info on it but, alas, its in german. I am new to CB and Ham radio in general, but what is the advantage of having FM on 11 meter?

    Also, OP2 OPEN, OP1 SOLDERED… you really get that whole range? Does is show the frequencies on the radio or just channel numbers?

  3. Gary Garcia says:

    a little confused. I just opened up op2 and left op1 alone. was I supposed to solder op1 for both 10 and 11? also when powering on for the first time, am I supposed to do anything from there? any help would be appreciated.

      Hello Gary and thank you for posting.

      My question to you is, how do you want to use the radio?

      As a CB?
      As a Ham Radio on 10Meters?

      For a “standard” CB: OP1 OPEN and OP2 Open (Unsoldered) and Select the BAND EU for the standard CB 40 channels in the USA : (26.965 MHz – 27.405 MHz)

      HAM Radio (10 Meter Only): OP1 OPEN, OP2 Soldered (How it shows up from the factory) , The BAND selection changes the Freq range)

      I would actually set it up Like this: OP1 SOLDERED, OP2 OPEN (Unsoldered). This gives the option of CB and HAM bands depending on your BAND setting. (DE is the standard US CB Band)

      When you power it on, select your Band you want to operate on. I would suggest AGAINST selecting the HIGH Power Mode, as in the standard AM Mode, the radio can NOT 100% modulate the carrier.

      Does that help you out?

      It is a great little radio, in my opinion.

      • Gary Garcia says:

        yes that helped out a lot, I actually did op1 soldered and op2 open. I guess I was confused because when I powered it up it shows EU and not DE and that’s the main problem I am having. Should it had automatically gone to DE? or is that a program setting?

    • Reverend Bow says:

      You have it setup for the normal “Freeband” mode, so “dE” is where you need to be.

      DE is if you set it up for “Freeband” mode:OP1 SOLDERED, OP2 OPEN (Unsoldered)
      Frequency Range: 25.615 MHz – 30.105 MHz

      It Should be like this: https://reverendbow.files.wordpress.com/2016/04/freeband.jpg?w=614

      Did you turn the radio back on while holding the AF button. Released the AF button and use the up/down buttons on the mic the scroll thru the country codes ending up on “dE” (which yields US 11 meters) Cycled the power to the radio again and it should retain the 11 meter band

    yup, that did it! It was the cycling thru the country codes that was the problem. thanks for the help on this and the clear cut instructions!

    Dumb noob question. How do you hook the Anytone to the Rigol scope?

    Show pics! Send me a pic!

    Thanks!

    Is there any way to solder jumper clips or dip switches across OP1 and OP2 for easy switching between modes?
