RUSSIAN MILITARY OFDM OPERATING ON 40METERS The IARU Monitoring System newsletter reports that the Russian military have been transmitting on 7000.8 kHz using OFDM 112 coding. The transmitter generating the unwanted noise appears to be located near the city of Severomorsk.
But Russia is not alone on the 40 meter band. The IARU also notes that Chinese Over the Horizon Radar has turned up several times on 7 MHz in the evening hours. It sometimes occupies as much as 280 kHz of spectrum and has been heard up to 7040 kHz using the well known sweep rate of 43.5 sweeps per second. Needless to say, hams who DX near the low end of 40 meters would like to see these operations gone from the airwaves.
