OK thanks, I'm quite interested in the ACT DSL rx's myself (with DPSD twin batteries alimentation) but I have many pending questions with that system, like the way it qualifies "bad" signals (failsafe from RX only or not ?) I will try to get more details from the manufacturer. I have sent my twin DDS10 rx systems for upgrade to PCM after I receive them I would like to organize some testing.
