  Sounds like a pile of surplus government equipment from one of the
services. The CV-89A is a device for converting levels (in this case,
the current loop from the teletype) into a pair of tones for
transmission.  It most likely does the inverse function also. In
short, it is a modem.

  The AR-88 is a general coverage shortwave receiver. 

  W2VZM is an amateur radio call. There is a server that is
telnet'able that could provide you with the 'who' behind the call.
