Luiton LT-310SDR

[Pez]

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.

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

Ok. I just looked online, it appears the at-5555 use a 5vdc ttl programmer

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 -

• 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.

In comparison, AT Audio is superior in all modes, output is better, sound quality seemed better and NR on AT seems to be better overall for listening than the Luiton. Did a bunch of on-air testing to a local SDR receiver so I could listen and compare the TX audio. Also did some comparisons with DX stations while the skip was rolling.

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.
