Out of curiousity, how does this compare with the FSK at 136Khz? I've
picked this signal up in California and Nevada.

I don't hear anything at or around 136 kHz.


I'm assuming you know what the GPS differential beacons sound like.

I guess I do now. Thanks. Based on your comment I did some
web searching and found
