thank you, I'll check the meter. as for the signal, I have several transcievers in the house, all assigned to each area. the codes in use are, B,G, K, L, and O. the outside ligghts work fine, and all the codes respond to the CM 15. the only problem is with one of the super sockets... it won't respond to the cm15 at all, but will respond to the transceiver commands. when I use the remote, the unit works fine. should I get a repeater? or does the system just need a good noise filter. all my lights are CFL's and only the bedroom lights and the chandeleir have regular bulbs. the china cabinet has a 25 watt bulb in it... amybe I should change out the super socket... the CH15 seems to be working just fine, its just not repeating the outgoing signal to that 1 unit... the coupler I have is the XPCP and it is new.
