[R-390] R-390A or R-390 Teletype reception

[Patrick]

Would like to know how to set up a teletype receiving station. Have R-390-A (3 of them and 2 R-390), an A/SGC-1A Radio Teletype terminal set (no manuals) and a AN/UGC-74C(V)3 also without a manual, additionally I have found on my stored treasures a CV-483/URA-17 Converter Frequency Shift also with no manual.
Can I some how use these units to set up a TTY receiving station? Have always been curious about TTY but never been able to set up a unit nor the knowledge to do so. Now that I have found all of these boat anchors maybe some one can help me do so.
If able to help, please respond directly unless you think that the response will add to the net knowledge.

Thanks and regards,

Pat
