You can't "mix" transmitters on your system.  You're going to have to
upgrade all your transmitters along with the receiver.  You can probably
sell the 900 mHz stuff on eBay fairly easily considering the number of
units "out there" and still in service.  Alternatively, you can search
eBay or http://www.tech-man.com for any additional units you might require.
