Happy summer John - The oldest ones I had used to use dip switches - inside the remote and inside the receiver. Same here. Mine's c. 1992-94 from Sears. Never had one minute of trouble with opener. Only have had to change batteries in the remote every few years. http://imageshack.us/f/151/searst.jpg/ |

All the remotes were pretty much on the same RF frequency (really realy old was 27 MHz, just really old on 300MHz). They modulated the carrier with one of a dozen or so audio tones to avoid interference with your neighbors. |

I had one of those until I had to replace it 3 years ago (defective opener wouldn't reverse when hitting something o tore up the door). Apparently, you would change it by moving the core inside the coil. -- Mark Lloyd http://notstupid.us "Eskimo: If I did not know about God and sin, would I go to hell?
