OTHR? Was: Dasher 6943 1110 UTC 22 Jun 2017

New one for me. About a 3.7 second period.
Still barely there, but almost gone, at 1216z.

Checking an online SDR in Idaho at 1310z, I hear and see the dash on 6943, along with what appears to be an OTHR burst. So now I suspect I was hearing just the dash, and the wide band OTHR was too weak to be received.

I think there are a few hf radars that precede their blast with a doppler correction tone thingy. Where's token when we need him?
