LF: CW beacon "BRK" on 137.00khz ???????

[Gerhard Hickl <gerhard.hickl@aon.at>]

Dear group!

I'm working on a new DC-CW receiver and while testing, I found a
CW-Signal on 137.00 sending "BRK" every 10 seconds.

I don't believe that this is a real signal on this QRG rather some
mixture in my MiniWhip or RX.

Another hint in this direction is that I only can hear it with the
active-antenna and not with my TX-antenna.

It's very weak and today it's noisy on the band so that's why I'm not
sure about the "B" in the beginning. BR would mean China.......

Does anyone know this station and it's real QRG?

73 ex tnx
