Re: [HCDX] Voice of Russia with interference
Rich,
9885 has VOA Spanish at 2300, which is jammed by Cuba. If you only heard chirping, you were lucky as usually here it`s a wall of noise.
Theory is that just one Cuban jammer puts out pulses which are individually detectable like that, while if you are getting a bunch of them, they merge together, overlapping. Ask Arnie? You might time how many chirps you hear per minute as I have done in some of my monitoring of Cuban jamming. In this case probably what we also refer to as bubbling.
As soon as VOR started using 9890, I complained about what a poor frequency choice it was, right next to Cuban jamming and VOA. Now they`ve added 7440 (via Ukraine apparently) from 0000, but deeper into the summer noise level.

I wonder when HCDX will get around to selling the WRTH 2010? I reminded the list owner about this months ago. (gh)
