I’ve recently noticed that on some transmissions, if I increase the gain past a certain point, I completely lose the signal but the noise floor doesn’t change. The signal doesn’t come back unless I crank the gain all the way to max.

I’m pretty sure this is a recent development. Any ideas what could be causing it?

I’ve tried different software (SDR++, GQRX, SDRangel, SDRTrunk), different host devices (my PC and Android phone), and changed just about every setting I could think of. Same result across all of them.
