Title: 15016.xx usb HF GCS, 1835 utc Feb, 28 2014
Post by: Antennae on February 28, 2014, 1840 UTC: Is this the right forum for this?
I happened upon some phonics.
It sounds like it just ended at 1835 utc. "This is H O out."

The voice was too funny, it sounded like a bored American football player. "Yankee, sigh..., quebec, etc.)
Now I realize it was ITU phonics. I wish I wrote them down to see if it spelled something.

Post by: glimmer twin on March 01, 2014, 0350 UTC: I just noticed that there are about 200(!) users on the U Twente sdr all sitting on HF GCS frequencies and totally freaking out on each transmission..."this is it"...."here we go"...."OMG that guy has an accent"... They are pretty funny but I don't think they intend to be.

No, Spy Numbers is not the right forum for HF-GCS receptions, although it is a common mistake. These should be in Utilities. I'll move it for you.
