Combining Digitrax Radio Receivers?

My Digitrax throttles will include both 402Dupelx and older throttles w/ Simplex operation. In the "LocoNet", can I plug both the UR92 duplex radio receiver and the older simplex UR91? I can't find any reason or technical data that says it is not doable. I'd like to run both.

The reason I ask is because the Digitrax website mentions certain simplex throttles will still need to utilize the UR91 which is no longer available from Digitrax.

 

Yes, you can plug both in and they will each work.

 

I ran the Sub that way for a time until I replaced all the 100Rs...never encountered problems but quickly bought more 400s - the only way to go, IMO.
