Woketman,
We don't have the issue here with positive or negative shift, there is only one standard.
I agree with you regarding the IPD Rx's Rock solid. What is more I ranged checked my ES a week or so back with the 12 Channel Synth IPD. Now I am used to good range but this just went on forever. Engine running was the same as engine off. Friends have reported the same range. I got bored of walking in the end. Exceptional.
Regards,

John.
