DishproPlus switch, bandstacked LNBs -- no signal

[Mistress]

I have several receivers hooked to a DPP switch.
I have a DishPro stacked LNBs out in the wind.
I have DVBDream 1.7a and a Skystar2 PCI card.

In the path from my receivers & PC to the DPP switch are tone switches. The 22khz side goes to the linear PBS sat.

Everything works great everywhere but DVDDream is only able to find signals on the linear PBS sat. Nothing on any of the DPP paths.
If I remove the tone switch from the path I get nothing except on E129, tp 12516.
LOF1=11250000. LOF2=14350000.

There was a post in 2008 that suggested changing the LNB frequency a couple Hz to compensate for "drift". It didn't make a difference here.

So, what next, expert friends?
Thanks

I'm afraid, you can not (reliably) combine bandstack LNBs with tone switches.
22kHz tone is used to switch between two different LOFs.
Bandstack LNBs already have two LOFs (for different polarizations). There is no way to add a third LOF using just one binary signal (22kHz in this case). How do you encode 3 different states with just one bit?!

You may trick the software and configure it to use several LNBs on the same diseqc input (one LNB is DishPro, another is a Legacy LNB with one LOF and 22kHz always ON).
But your diseqc switching will be intermittent, cause DPP switch does not understand diseqc commands when they are sent at 13V level.
If you wand combine circular and liner LNBs in one big assembly, do not use DPP switches.

added: the trick described above will work with WDM driver. if you use BDA driver, this trick wont work. BDA driver does NOT have direct control of 22kHz tone (it is controlled only through the relationship between Frequency and Lofsw values). Also, keep in mind that BDA drivers don't know what is a bandstacked LNB (software is changing Lof1, lofsw, Lof2 on the fly to convert them into parameters which BDA driver can understand). BDA driver also does not know that DPP switches (unlike DP switches) don't understand diseqc commands which are sent at 13V level.
