Looks like I blew my sband LNA.
I noticed that I could not hear the "beacon" sat signal on 2242.488, so checked. changed the LNA to another one, and signals came back - probably with a slightly higher Noise Figure (L-band LNA).
so - I opened the LNA and what did I find ? it is not a GaAs Fet amplifier as such, but a GaAs MMIC. Not really a problem, I have a replacement with the same pinout - only snag - it is SMD, so I hope my soldering and vision will up to the challenge.
LNA Spiritus Basta !
Why did this happen ? I transmitted on 2m with an antenna too close to the sband antenna. Oops !
