Greetings To All !
I just purchased one of these 'Anytone' SMART 10 Meter Amateur Radio Transceivers for my car. It is capable of both AM and FM modulation and is switchable between 4 and 8 watts RF power output. It is just slightly larger than a standard credit card in size and will fit just about anywhere in a vehicle which made it very attractive to me for mobile operation ! It is very easy to use and covers between 28.000 and 29.695 in four separate channel groupings. It can be readily recognized as a CB radio that was modified to operate in the 10 Meter amateur radio band and even sports a Channel 9 and 19 'emergency' channels which is a dead giveaway that it is a modified CB radio, at the factory of course.
It's a VERY cool little radio, I can't wait to give it a try during 'E Skip Season' this spring ! While it is impractical for use on repeaters it is a great little rig for working simplex DX on 10 meter phone ! The only thing that would make this radio even better is if it had a CW mode !
If anyone else has one of these and has used it I'd love to hear your comments !

It will do 8 watts but I recommend leaving it on 4 if using AM since when going over to 8 watts it won't fully modulate. I think it tops out somewhere around 70% modulation when in high power mode whereas low power mode will push the full 100% with ease. I turned the RF variable resistor inside to full power so it puts out right around 4.5-5 watts carrier on low power mode in AM and will fully modulate and only use high power mode if I am going to play with FM since FM doesn't need the modulation headroom for both sidebands like AM does. So when in FM mode it's perfectly fine to use high power and you will get full FM deviation after turning up the FM deviation pot inside. There is another mod for this radio to basically short out the modulator transistor either by a toggle switch or permanently to get to around 25 watts FM but it will disable AM entirely unless you use a switch. It's hard as hell on the final transistor and will need a fan added, but it can be done if FM is what you use mostly.
I have OP1 soldered and OP2 unsoldered to get the full 25.615 to 30.105MHz for export bands A through J. One thing to keep in mind when using this mode is it will have the standard CB radio band segment skip across the entire export bands so if you go to use it on the 10m ham bands you may find yourself getting confused with channeling but I only use mine for CB right now anyways so that's fine by me. Also don't forget that if you press RFG it will switch from 5 or 0 offset, so for example 27.185 would be "E" and 27.180 would be "P", thus turning on the radio you will see dE or dP to let you know it's in band D and either 5 offset or 0 offset.

Hi Kage !
Thanks very much for the excellent information on the Anytone 10/11 meter transceiver !! I really like the Channel Chart. very helpful indeed !! I had planned to create one of these using MS Excel but now I won't have to spend the time to do so, thanks to you ! I really appreciate it ! Very good to know about the 4 / 8 watts setting regarding full modulation, etc..
Also, the 25 watt option sounds very interesting too ! I will pass this information on to a fellow ham radio buddy who also has purchased one of these rigs for use on 10 meters, I am sure he will also appreciate this valuable info ! Thanks again for sharing this !
I too, have opened up my rig to cover the same 25.615 ~ 30.105 as you have. I do have one question, when turning up the FM deviation pot inside the rig, is it required to measure the deviation in some way for accuracy or is it just a matter of maxing out the pot and forget it ? I look forward to your reply !

With the FM deviation potentiometer you will need a meter designed to read your RF output deviation, or if you want you can do it by ear using a dummy load and a quality radio nearby with selectable bandwidth range with sharp cutoff. I used my SDR dongle for this and injected a sine into the mic and measured/listened for lowest distortion at +-2.5kHz deviation. If you have a ham ticket then simply hop on air after you think it sounds good and ask some others how it sounds to them. I don't think this radio will go that loud on FM anyways and probably tops out around +-5kHz deviation which is still allowed above 29MHz amateur I think..

Greetings Kage !
Thanks for the info ! I just ordered an 'Opek Trunk Lip Antenna Mount' on EBay, it should be here this Saturday so I will be able to install the rig into my chariot. I'll do a little experimenting with the pot and set it for optimum performance. I'll have a few guys listen to it on 10 meter FM and get some opinions. I also can listen to it using my Icom IC-746Pro HF rig for the initial setup.

Greetings To All From High Mountain Radio !
I have included a chart of the different channel banks and frequency allocations for a modded Anytone Smart 10 Meter Transceiver. Hope that it proves to be useful !

The channel chart does not show which banks work with which options with OP1 and OP2 I dont know how to change banks I had my radio set up for CB NOW I want to set it up for 10M simplex and work 29.3 and 29.6
I have closed OP2 now my radio comes up PH I want it to come up IH so I can get 29.600 any ideas Can anyone tell mee how to go from frequency bank H to bank I

Should just be able to power the radio on while pressing and holding A/F until the screen lights up, then use the channel up/down buttons to select a different band bank, power back off then on and you're set. To get the zero frequencies you need to press and hold RFG to select either xE (2x.xx5) or xP (2x.xx0) frequency offsets.
