Hmmmh, in universal LNBs the polarity and hi/lo frequencies are selected like this:

# command: # t tone off (universal LNB: low freq) # T tone on (universal LNB: high freq) # v voltage low (13V) (universal LNB: vertical polarization) # V voltage high (18V) (universal LNB: horizontal polarization)

You might try to increase the waits (W15 --> W50, for example) and then try to always first set the high or low voltage, command the diseqc switch and only finally set the correct voltage for the selected polarization.

If your current setup copes nicely with H pol but with V pol only after viewing a H pol channel try something like this:

The changes made:

1. Increase all delays from 15ms to 50ms (W50)
2. Always set up the high voltage (V = 18V, v = 13V) (for H pol) first
3. Set up the correct voltage (13V or 18V) only after the whole

command sequence.

I suspect that somehow your diseqc switch is not able to hear the commands unless your dvb-s card sets up the high voltage for horizontal polarization. This is only a wild guess, though.

CANADA!!

YES YES YES YES YES YES YES!!!!!! SUCCESS!!!!!!!!!!!!!!!!!!!!!!! I would never have come up with anything wild like that configuration. That gave the diseqc the kick! Thanks Sami. If you come around some day, I'll buy you a mäyräkoira of your choice ;)

Thanks again! I'm off surfing the sky!
