NPM used for testing Kuhne MKU23 and Chinese S-LNB

some results testing both converter.

I use
- Wifi 2.4GHz 24dB gain parabolic antenna put on the floor of my shack.
- down converter 2.4 GHz to 1.2 GHz (Band S to Band L): kuhne or Chinese
- TT S2-1600 PCI card as DVB-S receiver
- NPM V0.8 that allow attenuation when we use S2-1600

with Kuhne MKU23 I need to add 10 dB gain using TT S2-1600 STV6110 BBgain

with Chinese S-LNB I need to reduce saturated signal using 24 dB attenuation ( using software command to send pseudo AGC voltage to STV6110 chip)
