I have tried to change from a TBS6981 to a TBS6984 card.
However the signal quality seems to differ, which makes a swap a downgrade.
- Same PC-powersupply for both cards.
Quad LNB, where on of the cables is slightly (6-10m) longer.
Command line: ./szap-s2 -a 0 -H -c thor.conf -S1 "TV" -O25 -M5 -C34
Thor 5/6 satelite (europe)
Signal level is always reported as 74%, independet of cable length.
BER is always reported 0 on both cards, independent of cable length.
no option line for any card in modules.conf
111118 linux driver
There are no visible picture errors when using my TBS6981 receiver.
There are no visible picture errors when using a Sagem DVB-S2 receiver
There are visible reception error on TBS6984.
All inputs on the TBS6984 gives ~ same snr when same LNA is used for testing
snr is always reported as 100% for TBS6981, independent of cable length.
snr is reported as 97.2% on average for TBS6984 for the shorter cable.
snr is reported as 95.4% on average for TBS6984 for the longer cable.
Are there less power supply rejection on the TBS6984 which can cause this issues?
Are there any options that could be tested?
