... The RF signal spreads about 20Mhz +/-
from the 418Mhz signal which explains why the remote would
be able to control some of my 433Mhz equipment (lights,
etc). Weird!
The newer MX-3000s (Built after April 1 2005) have a more narrow band transmitter which is what makes them work MUCH better with the MRF-350 and MSC-400 (Specifically the RFX-250 antenna).
The older remotes were a little "sloppy", but that has been resolved. I have had much success with MX-3000s and MRF-350s/MSC-400s. We've done many of them and the reception was exceptional.
