I also have problems with 4 quad LNBs on a diseqc switch (1.0 and another 2.0) If I plug out the cable from the card and plug it back again (reset switch and LNBs) I can use szap to change the channels. I believe the quad LNBs have diseqc switch inside and at reset they are in backward compatible mode (Tone/Voltage). In Diseqc specifications/recommendations they recommend the diseqc LNB should ignore responding to Tone/Voltage commands when they receive one diseqc command. Unfortunately, I did not find the proper diseqc commands for the LNBs.
I will try today a workaround to reset the LNB before sending the diseqc.conf sequence in backward compatible mode: - switch to another LNB (hope the power will be cut for the one I need for the channel) - do the sequence for current channel t v [E0 10 38 FF] W500 (switch to LNB4 and wait 500) [E0 10 38 F0] W100 A W15 t (switch to LNB1, wait for power to stabilize, use back compatible)
If I am lucky enough the switch will cut the power for the LNB1 when I switch to LNB4.
Does anybody knows the Diseqc commands for Quad LNBs??
Thanks, Ilariu

Hi Grégoire There is a Diseqc command to reset (all) LNBs :
[E0 00 00]
maybe it could send in some cases.

Yes, it does,
Thank.
Tonight, I try to tune to one of my favorite radio station :
SSR-Espace 2;Radio Suisse Romande:12399:hC34:S13.0E
:27500:0:218:0:0:928:318:8500:0
And I got :

Tuning back to Astra (for example DMAX : DMAX;T-Systems:12633:hC56:S19.2E:22000:203:303=deu:503:0:12602:1:1113:0
) tune directly.
And then back to Espace 2 again :
Jan 26 19:07:42 ar vdr: [9259] frontend 0 timed out while tuning to
channel 254, tp 112399
Jan 26 19:08:47 ar vdr: [9259] frontend 0 timed out while tuning to
channel 254, tp 112399
In fact it only tune to channels on Astra 19.2E but no Hotbird 13.0E neither Astra 28.2E.
I stop vdr and restart :
Jan 26 19:09:49 ar vdr: [15712] frontend 0 timed out while tuning to
channel 254, tp 112399
Then I quit VDR and reload the driver : it then tune without any problem, directly.
Is there a way to achieve this without reloading the driver ?

Thank you very much,
