John, I have since obtained some of the articles that you kindly listed in post #35. The National Library of Australia turned out to be a good source for this kind of material (
https://copiesdirect.nla.gov.au/home), and more economical than Linda Hall. The remainder of that list will be for future acquisition. (Had I known about Linda Hall back when I was living in Dallas, TX, I would surely have visited it – KC is an easy drive from North TX.)
I have also found some additional journal references:
The Marconi Single Sideband Receiver Type CRD150/20B-SSR2; C.P. Beanland; Marconi Review 1949 January-February.
This setup, three HF receivers for diversity reception with “add-on” SSB/ISB adaptors, evidently preceded Marconi’s dedicated point-to-point receivers, starting with the HR92/93 and HR21 in 1952. The CRD150 looks to have been the diversity version of the CR150.
The Marconi Single-Sideband Receivers – Types HR92 and HR93; C.P. Beanland and F.I. Rockaby; Marconi Review 1952, pp.60-70
A new Approach to H.F. Receiver Design (GEC RC410/R); J.M. McAinsh & R.J. Bridge; GEC Journal Vol 34 No 3 1967
On-line,
“Philco Single Sideband Communications 1957” is at:
http://www.navy-radio.com/manuals/ssb-93224.pdf. This provides some information on American point-to-point receiver practice of the 1950s. (It is a very large .pdf, something like 150 Meg.)
The book
“Single-sidebands in Communication Systems: A Bibliography” is available at:
