Anyone capable of fixing inverted spectrum issue on tt s2-3200?

Anyone capable of fixing inverted spectrum issue on tt s2-3200?

[Newsy Paper]

Hi,

as the problem with the ORF HD transponder on Astra is now figured out and ORF switched inversion off again, we know know where the bug in the driver is. I don't know if the problem also occours on dvb-s(1) transponders but I'll try to figure that out.

Is anyone able to fix that dvb-s2 problem? Perhaps it would also solve the problem with some transponders on 1° west?

regards

Newsy

To verify whether an inversion will solve the issue:

Please try changing

line: #1313 .inversion = IQ_SWAP_ON, /* 1 */  to IQ_SWAP_OFF

in

http://linuxtv.org/hg/v4l-dvb/file/79fc32bba0a0/linux/drivers/media/dvb/ttpci/budget-ci.c

and check whether that solves your inversion issue. Please report your findings.

Manu

thx Manu for your quick answer. I tried that patch, at least on those 8psk 30000 3/4 on thor 1 West it didn't solve the problem, but I'm not sure if they really use inverted spectrum on that transponder.

ORF switched inverted spectrum off again, so I'm in search of an dvb-s2 transponder that has set inverted spectrum on in order to test your change. :(

ok this modification does change something as I have no signal on all dvb-s2 transponders that don't use inverted spectrum. I'm still looking for a transponder that has this inverted spectrum still enabled, so I'll give feedback as soon as I find one.
