well, i bought a 15-2103. i was startled to find that out of the box it powered up my rca tv and pioneer receiver (power functions was all i tested).

i am sorry to say that setting aux to 0013 and trying the advanced functions 247 and 251 gave me the same result as the discrete codes in the library here. :-( both codes toggle input attenuation.

i wonder if this is a bug in the receiver since every other pioneer receiver responds to these codes.

oh well, guess it was about time to replace the old thing anyway. still, a major disappointment!

thanks for all your help, jon and edmund. btw jon did you ever get a chance to look at the ccf i sent you?
