Thanks for your reply.
No luck yet....
Set to true south and clear sky. 44 degree in clamp-motor.
30-6 = 24 degrees dish elevation. Signal meter shows full scal signal..(not sure whether it is broken or not) but
twinhan software shows no signal at all. Mytheate doesn;t show anything.
should i change the LNB1 = 11300 and LNB2= 11300 (other thread said it is LO)
I don;t know how to check my USB receiver broken or not.
mytheatre detects the USB box, however red color letters Twinhan DVB-S VP7021. 0% -0%.
no idea how to debug the whole thing.
