[Milsurplus] Question ( RBS; submarine )

[mstangelo at comcast.net]

Didn't the allies hype detection by DF-ing to hide the fact they were finding submarines by message interception and decryption and detection by Microwave RADAR?

The DF-ing of receiver radiation is basically an urban myth. The radiated RF is miniscule and the DF receiver would have to be at a fairly close proximity to the reradiating receiver, which will put it at visual range anyway. The real reason is that in  shipboard radio operaton there were usually multiple receivers connected to the same receiving antenna, and the mutual interference from the same ship's receivers would be intolerable, especially when some receivers would be used for SIGINT and COMINT to search for and listen to enemy communications and other RF signals.
