Thanks to everyone who responded to my inquiry about using the MS-4 speaker with 2 radios. From all of the comments and opinions it seems like the best way is to have a separate speaker for each radio, unless you use a switch with resistance for the radio not being used. Another suggestion was possibly using a 2 input mixer device that would allow both radios to work without a switch. The bottom line is that no one recommended running both receivers into the same speaker without using a switch or mixer.
Thanks again for the help and advice,
