Min, max and recommended values for LNA, PGA and TIA

Hey guys, I’m trying to use my Lime without an external LNA so I’d be trying to max out the internal LNA. What’s the max value that I would be able to use for each of these gains and what would you guys recommend as values?

Just my non technical method:
One thing I have noticed is that the TIA gain has a huge effect on noise and intermod. I try to keep it at the minimum.
I advance the LNA gain until the noise floor starts to rise and then use the PGA to get the best signal to noise.
I go back and forth between these but usually it was best at first adjustment.
I use SDRangel to look at the signal while using the manual adjustments.

Awesome, that’s great advice. I’ll check out that software tomorrow. Thanks Axemurderer.

Hey! Nobody has ever proven I’ve killed anyone.
