FWIW, I can now answer the questions I raised in a couple of posts above:
#290 - the SX88+ (and thus presumably the SX88) does transmit both DiSEqC 1.1 and USALS commands at the "same time"(consecutively, I presume) if both settings are enabled.
#295 - the combo of the Spaun relay and the RF-remotely controlled 12V supply for it works fine. The relay switches between the steerable TD88 and the fixed dishes with LNBs connected to the DiSEqC 1.1 10-1 Opticum switch down the garden, and thus I can connect to (say 13E) via either route simply by clicking the RF remote control switch button, with no need to go into the SX88+ menus to make any changes - "Simples"
PS: the RF remote is stuck to the underside of the SX88+ remote with d/s tape, and it has a sliding cover over the button to prevent accidental changes from the switched LNBs to the steerable dish.
if you have possibility to see inside the metalic box of tuner and we have the tuner CIP ID we'll know the answer
