I started a new thread about the LT-310SDR here: Thread 'Luiton LT-310SDR' https://www.worldwidedx.com/threads/luiton-lt-310sdr.271257/

This radio has two different noise reduction features. One is DSP like the Anytone radios have, and the other one is AI Noise Reduction. The AI version is not like any I have seen before. The DSP in the Anytones is a game changer and this AI Noise Reduction takes it to a new level. Now Anytone...

My only concern with the microphone is that there is no menu option to select electret or dynamic. So there will be a small voltage going through the dynamic element. It won't hurt it, but when I make an adapter, it will have a capacitor to block the dc current. Let us know how the programming...

Big thanks to Simon the Wizard, he has some information on his site about this radio. Here is the microphone pin out, programming cable pin out along with programming software: https://simonthewizard.com/2026/05/31/luiton-lt-310-sdr-pin-out-download-software/

The performance of the radio overall is good, although the adjustments inside did not seem to do a whole lot. Maybe there is an engineering menu? The AM modulation will do 100% on power level 1 with a 1.5w carrier swinging to 6w with a whistle. Power level 2 gives 3w swinging to 10w while level...

The inside of the radio reminds me of the Chierda S890, and the microphone appears to be almost the same. It is interesting to think about who made the radios, or at least who made the parts. The "Mini" printed on the board made me remember this radio, the TYT SSB Mini...

The chassis of this radio looks very similar to the Anytone Smart, just slightly longer. The 310SDR has a taller display, which is easier to read.

I encountered a problem on my unit when I took it out of the box. The main radio knob was stuck in like it was pushed on too far and wedged against the face of the radio. I was able to pull the knob out, but the first time I pushed it, it got stuck again. Also with the knob pulled out, it still...

The Luiton LT-310SDR radio that I received came in an unmarked box, and the radio itself has no name or model number. This is not a big deal because the radio itself is what we are after. It came with all the normal mounting hardware and power cord, along with an owner’s manual printed on copy...

Out in the garage today, I heard several California stations working the east coast. I tried, but they couldn't hear me...

What would happen you put some audio on the external modulation?

CQ, CQ John Crapper standing by!

Standing by on 35USB as I do some stuff around the house.

Yesterday conditions were not that good, but I did hear a station from downtown Mexico City calling DX in Canada that I could not hear. USB on 35 for tomorrow sounds great, although it's going to be another rainy day here. Hopefully the lightning stays away...
