[IRCA] B-P-B-P Mystery station on 680 KHz

[Les Rayburn <les@xxxxxxxxxxxxxxxx>]

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.
