Hi Glenn,

I'm not disputing this...but the AM-3007/URC is part of several Navy sets, such as the AN/WRC-1, AN/URC-35, and a AN/BRC-something or AN/BRT-something (I can't remember anymore) that we had on the subs.  It would seem a strange limitation for such a widely used unit.  Perhaps the key phrase is "continuous duty transmit."

Maybe some list members who were surface navy can report their experience.  But submariners likely won't have experienced such failures.  No ship transmits less (but listens more) than a ballistic missile submarine during the cold war.  Typically in a 70-day patrol, the only RF transmissions leaving my boat came from the marine VHF-FM handie-talkies that we used as officer of the deck to talk to tugs and pilot boats when leaving or coming back to port.  Even the surface navigation radar and the IFF transponder usually had their power fuses pulled and locked away.
