Luiton LT-310SDR

Looks like Moonraker are out of stock at the min

I had little time so just preliminary:
Pros:
1. Small
2. Wideband,
3. Cheap (Paid 44GBP shipped)
Cons:
1. Raspy SSB,
2. Microphone plastic cord sucks.
3. So-so tx audio. Tinny, quiet, flat (but readable). Mic change didn't make a difference. Not audio monster for sure.
4. Tx lag: delay between microphone input and audio going out is around 300ms.
5. Noisy RX even on dummy load. Hiss is terrible. Hard to use without (A)SQ engaged even on lowest AF volume setting. Unacceptable for me.

For 10m radio it should have split and ctcss.
More to come when I find some time.

p.s. anyone got written description what jumpers inside are for? I'm tired watching YT mumbling. TIA.

The man from del monte he say it's Sh*te

Thanks for that Chris. Doesn't sound very promising. Maybe some or all of the issues will be addressed in later board revisions. For the time being i think it might be best to give it a miss..

I asked for schematic, maybe there is some place for improvement.
I didn't have a time to measure, but I wonder what is bias set on final transistor.

Final Bias and fiddling with the audio amp might be the only things that are easily alterable (if you're good with SMD)

I think everything else will be changes to the actual firmware (not the configuration), it's why I posted about getting a copy and seeing if it's encrypted or crackable.

I've got a query open with a seller for 5 'samples', if I can get them under £50 each I'll buy them and rip one apart to extract the code.

No UK distributers for the LT-310SDR (as yet) so the Moonraker Atlas will be the safer bet when it comes to warranty - when it becomes available of course.

I sold that junk yesterday. Jupiii!

[UK-Ham86]

For £50 I don't care much if I destroy one by hacking and modifying.

See Moonraker adding another one to their multimode line up, the Triton. Looks same as the Titan but without the split screen of.

Just seen there's a review of these on the TM1 Youtube channel

Probably similar to the midland 8001

[Transwarp]

Probably, most recent stuff seems similar or 'clones'

I am not going to name any names, but many of the reviews seem to show the radio in a positive light without mentioning any of the downsides.

I have noticed it on a few other reviews too, even the original Grant 2 got good reviews, but then when people actually took delivery of theirs the flaws soon became apparent. I was an early adopter of that radio and I don't want to get caught again in the same way.

Off topic I have an Anytone AT-778UV II, had it for a few years and it's a good little radio for what it is. In time l'd like to get hold of a matured AT-5000 to go with it.
