Experimental Station Heard on 30 Meters

From the ARRL Letter:

IARUMS has received reports of short “beeps” exactly 1 second apart, as  well as frequency hopping between 10,108 and 10,115 kHz and 18,834 and  18,899 kHz. The signals are believed to emanate from a site near Chicago  associated with an FCC-licensed experimental operation involved with  low-latency exchange trading on HF (see “Experiments Look to Leverage  Low-Latency HF to Shave Microseconds off Trade Times  <http://www.arrl.org/news/experiments-look-to-leverage-low-latency-hf-to-shave-microseconds-off-trade-times>”).  Although Amateur Radio is secondary on 30 and 17 meters, Experimental  licenses may not interfere with Amateur Radio operations.”

YCCC member Fred Coelho, WX1S writes on the YCCC reflector:

“More on our 30 meter intruder.  I’m not sure if this is what we were  hearing last month but a signal (beep) at 1 second apart sounds about  right.  I copied this from the latest ARRL letter.”
