Re: [IRCA] [NRC-AM] B-P-B-P Mystery station on 680 KHz



One would also want to include the possibility that it's a harmonic. Integers in "interesting" ranges which have harmonics on 680 include 340 kHz, 170 kHz, and 136 kHz. But then there's also the Chelobityevo NDB "BP" on 680 itself in Russia, (found in a simple Google search) but perhaps you've ruled that one out? Which beverage was it on?

Would love to hear the actual recording.

Good luck,

Just received a fascinating recording from famed DX'er Hannu Tikkanen, who records from the top of the world in Lapland using a Perseus SDR and a 3,000 foot beverage. He records in this nearly noise-free cabin location for a week, once per year. Then spends the rest of the year combing through those looking for rare catches. 

Today he sent me a recording of KKGR 680 in Helena, MT with three
    crystal clear ID's. In the background you could also easily hear
    KBRW in Barrow, AK. But clearest of all is a Morse Code identification at about five words per minute. It sends out B-P-B-P in a four letter group. 

Hannu had no real ideal who the station might be. He suspected an
      Asian station due to the time of day for the recording. At first I
      thought it was possibly a beacon of some sort, perhaps related to
      British Petroleum, but it's clearly a four letter group, not a two
      letter group repeating. Is 680 KHz allocated for radio location or
      beacon service anywhere in the world? 


Any help in solving the mystery would be appreciated.
