LimeSDR-mini wanted

i might have one but i was never really to good with it and not sure if it was fully functional.
i havent used it in a year or so and i know for sure the Receive work but not sure on the Tx.
i remember i did some firmware update and i think the Tx lost sensitivity or something.
if someone wants me to run some tests and figure out what works and what dont i would be willing to sell probably.

im in a windows 11 enviroment but i probably could load some linux live distro or if i had to i could do a seperate hdd install but i prefer to stay in widnows 11 if possible.
i also wanted to add i have alot of other items to go with it.
i have 3 or 4 SDR’s (Elonics E4000) and 3 R820T2 or something like that and alot more then that.
if you are serious let me know.
my email is tdbone1@hotmail.com
i probably should have started a new thread but i really wasnt looking to seel. i always check back about every 6 months or so looking for that quick scan think like the hackrf has.
this time i bumped into a thread where people were looking for a lime mini and thought i might reply.

maybe there is nothing wrong after all.
i booted into ubuntu and installed some software.
here are the results

oh i see something on the rf loopback test.
i did this test with a 3" coaxial dipole antenna on Rx and a terminator on Tx.
ive done this test before with both off and same results.
only think (that i remember) is that maybe i need to go into limesuite and do something on the SXT tab first then calibrate.
i forget.
