[Milsurplus] Question ( RBS; submarine )

[Hubert Miller]

Ray, you nailed it. 

The legend originates from early war desperation to explain the seemingly unstoppable U-boat onslaught.

I am still not buying it, the Afghanis in there mud huts believe that the Americans can hear their conversations with drones five miles above them. QRP operations in the Ham bands are a wonderful thing but my experience of running low power CW and AM left me with the idea that life is too short for QRP, lots of time spent calling other stations or CQ with little response. If all the stars and planets are in perfect alignment sometimes they get lucky and have a short exchange and call that a QSO, but that’s just me.

I would have thought German surface raiders in there short period of time in operation relied on things like patrolling know shipping lanes and approaches and visual sighting of smoke way before they would use something as sketchy as receiver LO detection. And as to the noise floor remember that we are talking about a ship that also had many electrically powered motors and other potential noise sources. 

No, if no one here can’t sight a document I am sticking with LO radiation being an issue in using multipole receivers in the same location and the idea of long range LO direction finding a myth.
