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: 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… Interesting to note: if you crank up the Modulation adjustment too far, it just quits modulating.

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… That ain’t 100% Negative, and starting to Flt Top The Positive Peaks…
Yup, that was the most modulation I could get out of it…. Meter (We are on the 20 Watt Max Scale now): So lets try the HIGH Power Setting Hold onto your hats fellers, that mean 8 lip cutting watts of carrier! So here we go: I want to see 100% Modulation with no over modulation on the negative peak, and no Flat Tops on the Positive Peaks. I don’t look for “SWING”, I look for Modulation Envelope. Then I switched back to AM, still on LOW POWER, and modulated it using a 1 kHz Signal into the mic element. I checked the FM Carrier as well On Low Power: The Set up was: Power Supply, Anytone Smart CB, Diamond Antenna SX-600, Dummy Load, and Rigol DS1102E 100 MHz Dual Channel Digital Oscilloscope.įirst I checked the carrier in AM in LOW POWER Mode (on the 5 Watt MAX Scale): So Lets see what it will do from the factory. Mine ended up like this (the Flux was cleaned up after the photo was taken…):Įnough said about that…. Warm up the soldering iron and follow your heart…. I’m willing to bet where 99.999% of anyone that reads this Blog will set this radio up…. Here is what the OP1/OP2 jumpers get you in their given Configurations: It Comes with: OP2 Soldered, OP1 Open (10 Meter Amateur Radio Band Only) So First things first: Get it on the band you want: Look at the MODE SELECT portion of teh board… The Power comes from a 13N10 QFET MOSFET (Upper Left Corner)īut what are all the rest of these little things? What do they do? What does it all mean?Ĭalm down, the only thinks of major importance to the normal operator are these: 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: It Takes a soldering iron, solder, and a little bravery not to fear the dreaded world of SMT (Suface Mount Technology) 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. Not counting the Hardwired Mic, the radio 4” Wide, 4.25” Deep and about 7/8” tall. Size: This little radio is just that… LITTLE. Lets take a look at these little critter and see what it is all about: Here they are, fresh off the Brown Truck… (For Reference, the Knife’s total length is about 7 1/2″) 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. Normally, a radio without SSB doesn’t even get my interest, but what the hell…
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. Albrecht AE-6110, CRT ONE)įirst, 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. I will try a few simple things first, but without a schematic (and rumor has it there never will be one available), it will take a bit of signal tracing to find out were the microphone preamp circuit is hiding in this little bastard…Īs the old saying goes: Where there’s a will, there is a guy with a soldering iron… and no morals… That would be me… 🙂Īnytone Smart CB (a.k.a.
I can live with the 3kHz top end limit, but that Roll Off below 300Hz… well, we have to do something about that. That is what you call a fine example of “DX’er Quality Audio”… and it just don’t fly around these parts… As you can see, that is a pretty damn accurate Spec. The Anytone is advertised as having a frequency response of 300Hz-3kHz. Green Line is FM Mode (looks like I could turn that Deviation up a bit more): I did a check in AM, and one in FM, then used SpectraPlus to take a look at the bandwidth: Using the stock microphone (meaning I have not modified it… YET….

This time, I was using an RTL-SDR Dongle and SDR# software with the Bandwidth set at 10kHz. I was able to do a bit more testing on my Anytone Smart.
