ICW orginally was CW interrupted at AF with an interrupter wheel. See p. 129 of 'Radio Engineering' ed. Roy C Norris, pub. Odhams Press Hello all, Look for example "MIL-STD-188-140A" Appendix A .....
Hello all, Look for example "MIL-STD-188-140A" Appendix A ............ 20.2.1 Interrupted continuous wave (ICW) ICW or on-off keying (usually associated with international Morse Code) can be used wit
snip "CW" - "continuous wave" - means just that; a steady unbroken unmodulated carrier wave; "N0N" (or "A0" in old money). Morse code is mainly sent by interrupting the carrier so how can it possibl
I was taught that the term CW (Continuous Wave), was coined to differentiate between the 'pure' oscillations generated by valves or HF rotary generators and the quenched or interrupted oscillations g
For some reason this didn't seem to make it onto the reflector first time round so here goes again: Recent discussions on "CW" and "Morse" have brought up some interesting points. Does a mode that is
MCW-- AM MODULATED TONE, BOTH CARRIER AND TONE KEYED KEYED TONE-- AM MODULATED TONE, ONLY TONE KEYED, CARRIER CONTINUOUS FSK-- FREQUENCY SHIFT KEYED, VARIOUS SHIFTS USED BUT 400 AND 800 CYCLES COMMON
I suspect coast and ship stations used MCW on 500, and CW on working frequencies. Am I right, Mal? John F5VLF Attachment: signature.asc Description: Message signed with OpenPGP using GPGMail
