Signal Kilo Bravo

Signal Kilo Bravo is broadcast from the WKML Broadcast Station located a bit southeast of signal Alfa Lima and far south of Fort Constantine.

Head inside the station, and you will find the activation switch for the radio signal. It's located on the wall to your right, behind the power generators.

Following the signal leads you to a Sealed Cistern at the foot of the drop-off, due south of the south corner of the WKML building. Entering the grate, you find yourself in a short drainage tunnel, blocked at the far end by sandbags. To the right side of the desk is the Explosives Bobblehead that adds 10 points to your Explosives skill.

Along with the bobblehead, you will find the following: one RadAway, two bottles of purified water, one stimpak, one Rad-X, a .32 pistol with 5 rounds in a box, a Stealth Boy a fission battery, and a lunchbox.

Morse code translation
Like the signals from most of the other drainage chambers, it sends:

This signal, "CQ CQ CQ DE / KB KB KB K", was explained by Mark Lampert, the Bethesda sound designer. Quote :

Parsing the message, we get the following:

CQ -- calling any station ("seek you")

DE -- 'from'. The reason this Spanish/French form of the word is used is simply to shorten it as it's a common word to use. Compare sending DE -.. . to sending FROM ..-. .-. --- -- Consequently, operating in CW means heavy use of abbreviations, dropping unnecessary letters, and other handy ways of compressing your message length by use of what are called 'prosigns' and 'Q-codes'.

repeated three times -- that way if you miss it the first time or copy a character incorrectly, there's a chance for error correction

K -- means 'over' and a reply is expected

Last, but not least, there's a pause as the station's operator momentarily listens for any replies. Hearing no replies, he/she resumes 'calling CQ'. Of course in this case our operator is long expired and we presume that the radio is simply transmitting a message from memory, operating for as long as it's still supplied with power.
