Set up a T3/RP1 last year along with two RK3s. Tech support indicated that the signal out of the CB and RP1 could be tied together at the input of the connecting block, and it worked well for over a year.

Today the T3/RP1 does fine, but the RK3 has a strange issue. It will run the zone 2 functions on the Integra receiver, fire off the CD changer, BUT it will not do channel macros on the Motorola cable box (for cable music channels).

Possibilities:

1. Bad flasher on the cable box? Don't think so, all is well operating the Moto box with the T3.

2. Bad RP1? Subbed it, no change.

3. RF interference? Took the antenna off, no change.

4. Noise naturally emanating from the RP1? That's what I think. I pulled power from it and normal functions returned, macros on the RK3 hit 100%. I also left power to it and pulled the Phoenix plug and the same 100% reliability was seen.

Anyone seen such a critter before? Couldn't call tech support on Saturday...
