If you are looking for historically-accurate matches for the 1940 GO-9 0.3 to 0.6 and 3.0 to 18.1 MHz liaison transmitter:

1.  Rule out RU-4A, RU-5A, and RU-14.  Those are command set receivers used with transmitters GF-3, GF-5, and GF-9, respectively.  They are also very rare today.

2.  Rule out RU-6.  It is a liaison system that uses two CBY-46048B receivers and is very rare.  It also dates from 1937, while the GO-9 dates from 1940.

2.  Rule out ARA or ARB.  Those are command set receivers eith top coverage of 9.1 MHz.  There are the instances of USN using C-131/AR-equipped R-26 and R-27/ARC-5 receivers or even the ARB with the AN/ART-13 in remotely-controlled installations, but these were not used with the locally-controlled GO-9.

3.  The most appropriape matching receiver systems for a GO-9 are:

-  RU-19   0.195 to 13.575 MHz.  It normally uses two CW-46048D receivers.

-  RAX-1.  0.200 to 27.000 MHz.  A complete three-receiver RAX-1 is rather difficult to put together today, but it would be the best of all candidates.
