from Radiomuseum.org Model: SSB Adaptor RA-63 - Racal Engineering Racal
Material Metal case
Shape Rack
Dimensions (WHD) 483 x 90 x 325 mm / 19 x 3.5 x 12.8 inch
Notes SSB Adaptor matching RA-17 family receivers, improving the reception of USB / LSB / ISB signals by means of a product detector.
The 3rd IF of 100 kHz is mixed with a 82 kHz oscillator signal to result in a new IF of 18 kHz, mixing with a stable 18 kHz oscillator signal allows to extract the sideband audio.
Variants: RA-63G for British market with European tubes, RA-63H for US market with American tubes and RA-63D with crstal controlled 82 kHz oscillator instead of LC oscillator.
Net weight (2.2 lb = 1 kg) 7.5 kg / 16 lb 8.3 oz (16.52 lb)

racal: RA-63 SSB Adaptor - Variants
Martin Bösch
01.Oct.06
  1 Variants of the RA-63 SSB Adaptor:
RA-63A: for use with receivers with 100 kHz IF out
RA-63B: for use with receivers with 100 kHz IF out, US type plugs and sockets
RA-63C: for use with receivers with 465 kHz IF out
RA-63D: for use with receivers with 100 kHz IF out, improved stability through
    crystal controlled 82 kHz oscillator
RA-63E: for use with receivers with 455 kHz IF out

RA-63G: identical to RA-63A, improved stability through reinforced side panels
RA-63H: identical to RA-63B (US plugs / sockets), improved stability through reinforced side panels
RA-63K: identical to RA-63D, improved stability through reinforced side panels
RA-63L: identical to RA-63E (455 kHz IF), improved stability through reinforced side panels
RA-63M: identical to RA-63C (465 kHz IF), improved stability through reinforced side panels
