I have met with 4 versions of this radio :

- R-123 - the original version

- R-123M - electronically little bit modified version

- R-123MT - M type that can be remotely controlled :

- on the left side of the radio is the connector for the remote controller

- all the tubes in module nr. 7 were changed to 6Н28Б-В type tubes

- R-123Z - if I know well, then this the polish version of the "MT" version

the differs from the MT version, that the power supply drives with 750V

the final GU-50 tubes, so the output power it significantly higher
