Yes, but only the 3.3V TTL 3 wire types (RX, TX, GND). Some are 2 wire (multiplexed) and will not work with these radios.

Luiton LT-310SDR

Thank you very much! I have the original anytone at-5555 - 3 wire programming cable. Not sure if it is 3.3v but I know the pins on the main board socket to connect it are RX TX and GND. Not sure if you are familiar with that one. I guess I could look at the anytone at-5555 mainoard schematic and see if the ic that the programmer is connected to uses a 3.3vdc to the chip. That would tell me if the cable should work? Or is there a simpler way to just measure RX or tx to GND wire for 3.3vdc? Appreciate any feedback
Can someone please confirm. I got the USB to serial adapter and a RJ12 cable to make the programming cable, what is confusing me is the wiring. The cable shown by Simon built shows TXD and RXD reversed of what the radio RXD TXD is, Is this the way it should be? The TXD for the USB Programmer goes to the RXD connection at the radio , GND-GND, and RXD programmer side to TXD radio connector side?
Picked up one of these and am working on a video but really wanted to compare it against the AT-5000.
Thoughts so far -
The Luiton is an interesting radio for sure and super tiny, but so far it would be limited to use for SSB in my mind and even that audio quality is lacking.
If I didn't need one to make a video and could have tested it in advance before buying I likely would not buy one of these unless the size was absolutely necessary for some reason.
Thoughts so far -
- It works fine for basic SSB, audio is a bit muffled IMO
- AM and FM audio is severely lacking (the nice way of putting it)
- AI Noise Reduction is interesting, fairly effective but cuts station audio too much even though it cleans up the noise.
- Noise Reduction (non-AI) adds a lot of weird artifacts like older DSP systems
- Slight delay on TX audio - watching the meter this was interesting to see the delay. I also listened to the audio on a monitor radio and the delay was definitely there.
- When NR is on - it effects TX audio as well. I didn't figure out if you can make it RX only but it was interesting to try whistling and see it not move on the meter at all. Pretty effective at knowing a voice compared to a whistle.

Interesting bunch of info. Thanks for offering it guys. I bought 2. 1 for the Denali, don't want to bang my knee on it, the other for testing in the shop. Haven't tried it on AM yet but SSB seems pretty good. I do like the clarifier feature being adjustable for tx, rx or both, havent really had much of a chance to experiment with the AI feature. Adjustable fr out is nice.
Your cable should look like the one on Simon’s website, and like the pics that Shadetree Mechanic posted…the RXD lead goes into pin 2 of the RJ12 plug, the ground lead into pin 3 and the TXD lead into pin 4. I made that cable some time ago and it works.
How in the programming do you change the AM modulation. Or am I missing something. I've yet to find it or get it to change.

I got my USB-TTL cable from Amazon today, clipped the Dupont connectors off the three wires (TXD-GND-RXD) and crimped them onto a 6 pin modular plug (RJ-12). It works !!!
Here is the cable I got…
USB-TTL cable
I used the Midland 8001-Pro tuning software (linked above in Shadetree’s post #6) and could adjust deadkey levels for all three power settings, adjust modulation on AM, USB and LSB, and adjust deviation on FM.
And most of all…I could adjust the volume level of all modes, so now volume setting 1 is nice and low
The software did help with the stock mic, but the overall tone is still “stocky”. But you can get a bit more audio out of the stock mic with this software. With my 4 pin mic-adapter cable, the audio out of my Astatic 575 is really good in all modes. You can adjust the parameters for the particular mic you are running. It is not a ‘one setting fits all”.
The software is a bit odd. There are various adjustments for Low Band, Mid Band and High Band. My guess is those are for the various frequency ranges. Mid Band generally refers to the standard 40 channels over in the UK, so I guess there is a frequency range for each of the bands, and you can make adjustments as needed across the entire coverage range of the radio. I only messed with the Mid Band Low Power setting although my dead key settings seemed to carry across the entire range of the radio (mostly).
This is weird…
The software makes the adjustments in real time ! As you adjust deadkey in the software, you can see the adjustment on your meter…so have the radio connected to a meter and dummy load as you do this. The radio does not indicate it is in transmit…but it is transmitting when you make adjustments.
I guess if you have an actual RF test set, this would be cool, but I only have a golden screwdriver, so I had to make the modulation and deviation adjustments in the software, and then swap to my mic and transmit while using a monitor radio. There is a “write to radio” menu setting, so after I got the settings adjusted to my liking, I did write to radio, even though the changes happen when you adjust the parameters. As always…read the radio first and save the factory parameters.
One other thing…not sure what all these settings are for, or how they are applied, but I did find with the stock mic that FM deviation and audio sounded better with a lower setting.
The factory FM deviation was set around 22, but it sounded better down around 8, so cranking everything up to “11” is not the way to do it.
