Variants of the RA-98 SSB Adaptor:
RA-98A: British type coaxial connectors, no internal crystal controlled 188 kHz oscillator,
need external 118 kHz source for hich stability ECSS operation.
RA-98B: US typ coaxial connectors and Monitor jack socket, no internal crystal controlled 188 kHz oscillator
RA-98C: broadcast version of R-98B
RA-98D: with internyl crystal controlled 118 kHc oscillator with crystal oven
switched by AGC - control knob.
RA-98E: with transistorized coupling circuit for use with transistorized receivers as RA-217 and RA-1217
RA-98F: RA-98A modified for use with RA-317.
