And so far in the book, there is no mention of voice radio other than a limited use short tange FM system for spies to talk up to aircraft..</p><p class="MsoNormal"> </p><p class="MsoNormal">My Father in law was a radioman in the battle of the bulge but I didn’t get around to asking till it was too late.</p><p class="MsoNormal"> </p><p class="MsoNormal">I guess there is no way to re-create it, so unless there are recordings, I guess it is gone.</p><p class="MsoNormal"> </p><p class="MsoNormal">Apparently SSB was discovered in 1915 and patented in 1923 or so? It was used by high commands in WWII to mask normal voice, but I haven’t found much about its juse in WWII.</p><p class="MsoNormal"> </p><p class="MsoNormal">I guess by WWII, everything had a BFO or the superregens too the CW came out as tones just like today?</p><p class="MsoNormal"> </p><p class="MsoNormal">Bob, WB4APR</p></div></body></html>
