No. The TM751 has an RF receiver daughterboard but no RF transmitter.

Since the RS/OS wireless protocol has been published I will try to design a
module to allow their use with roZetta and with the ZX-24 version of the
AHT. It will, however, have to wait and assumes that someone will loan me a
wireless unit to experiment with.

I've always taken the approach that the devices need to operate
independently of anything I design to monitor them. I just try to eavesdrop
on the conversation between transmitters & receivers.
