RX888mk2 @ 120msps, VHF sensitivity -10dB (at least), also affected by bandwidth

Hello All

THANKS to Simon for the additional RX888 features, what a time to be alive !

I've noticed that VHF sensitivity is degraded at 120Msps, somewhat still at 64Msps, seems OK at 40Msps.

ADC vs Sensitivity better on HF, sensitivity does not seem to vary much by Msps, but BW does affect.

Oddly, 2MHz (BW) is most degraded.

I know this is not exhaustive testing (in a real work deadline project), but just wanted to give a heads up.

Loving the HF coverage including 6 meters !

Thanks again !
