Analog or PWM

[AlphaOmega]

I do no thave a RA yet but will most likely be purchasing one soon. I will be running my radion 30 pro and I am confused as to which uynit I need to purchase. Do I need analog or PWM? Also from what I'v ebeen reading the new units let you use either so if that is the case why would anybody pay an extra $20 for the analog? Also I am most positive I will need the RF expansion, is that correct?

If you want to control the radion you need the RF. Yes the parts are the same but analog actually requires more hardware so Roberto still charges extra to come default. PWM and analog for you won't make a difference, depends what other hardware you might want to control. To change it you have to break the seal on the relay box and re-glue it so it makes sense to order what you need.
