648 Radio Repairman, FM Equipment

For the earlier SSN 648 title, Radio Repairman, FM Equipment, Appendix B suggests reclassification to SSN 174 or 649 after individual Qualification Card and job-specification review. The asterisk ties those suggestions to the earlier AR 615-26 title, not to Signal Electrician, the title listed for SSN 648 in both June 1944 and June 1945.

Source extraction notes

Predecessor title from the AR 615-26 column: Radio Repairman, FM Equipment. Suggested conversions/remarks, as printed: *174, 649. Asterisks bind the suggestions to the correspondingly marked earlier title, not to an unmarked present-title meaning. The Present Title column is the manual's June 1945 meaning: Signal Electrician. It is not a present-day MOS equivalence. These are suggested reclassifications subject to individual Qualification Card and job-specification review, not automatic or present-day equivalents. The table gives no row-level calendar effective date. June 1945 is the manual publication date, not an inferred individual conversion date.
