Following up on last month's story about the return of
Russian over-the-horizon radar on the HF ham
bands (although without the level
of interference caused by the Russian "woodpecker" a few decades
back), the International Amateur Radio Union (IARU) that a Chinese
over-the-horizon radar system is now transmitting on 6.999 MHz, with a
10-kHz-wide signal that sometimes covers up the very low end of the 40-meter
amateur band.

The ARRL Letter also
reports on 40-meter QRM from military stations in Kyrgyzstan
and Radio Eritrea (as well
as a jamming signal from Ethiopia).
