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 …
