I'm almost never offended. I frequently give meta-advice in these forums (how to ask the question for a better chance at a good answer). Those posts really are intended to help the person who asked (and/or any other beginners reading the thread later) to get a useful answer. They aren't intended to indicate I was offended nor to offend the person whose question I'm critiquing.

I have no interest in that RF thing. I think you're probably refering to the RF_receiver_IR_transmitter, which is a seperate part, rather than to the actual RF transmitter, which is soldered inside the 2117. But either way I don't want one.
