LimeSDR is complex piece of hardware, therefore some of us "old folks, 50+" may have some difficulty during our learning curve, all up to level of useful use in accordance to our needs.
Lime is my SDR No6. (2xSDRPlay, 1xRTL-SDR, 1xFR24dedicatedSDR, 1xAISdedicatedSDR) all used both on Linux, RPI and Win. Personal experience, ham since mid '70ties, electronics and aviation background, 20+years in IT too, from programing to HW distribution and repairs.
And with all that on quick start I needed assistance from Marty because I was not patient enough to read bellow to chapter 4.
Lime is nice piece of hardware, please look at it like nice learning tool not like some piece of consumer electronics with on/off switch only.
Now going to resolve cooling on my LimeSDR, at the moment that is my major concern
