How much whas difference releted to Techno Trend TT S2-3200.
I have problem to be solved to receive Eurobird 2D (2,4m antenna) here in north.

hello,
yes, KNCone is between 10 to 12 dB more sensitive than S2 3200.
constructor say -100dB sensibility at SR1000.
I have made the measures with my DTA107 + attenuator directly connected to Tuner cards.

measures can be different with usise of LNB that give more noise level and "sensibilty" begin not to capture a signal very low but more a C/N ratio very low.
I come back at home Monday, if you want I can send you a KNCone card to test.

take care to get the good model.
They have perhaps now different models.
the model that are same:
-KNC One HD
-Mystique Satix DVB-S2
-Satelco EasyWatch HDTVS2 PCI

some Knc-one have also 1 RF ouput, don't take them the sensibility is lower.
