So, as long as only one trasnmitter is ON, there is no problem. That's why you can unlock your car, when all the cars and remote door controlers are on the same channel.

Regarding the SMD or DIP case, I suppose you have to call Bruce and ask him.

Is rentron still operating? I've called a few times and only get voicemail. No response to an email.
I'm off to Washington, DC next week and would like to order a few CIP-8 chips to collect on Friday but time is running out. May have to go with PT2262/72 chips.
