5000 to 6000 kilometers off the finish line is misleading.Reception on remote monitoring in Perseus or Kiwi net sets
at Near and Middle East target like Kuwait or UAE / Qatar target describe
an excellent useful signal - nearly free of Iran shortwave jamming.
Jamming against former IBB now AGM United States Agency for Global Media
(USAGM) / VoA Farsi on MW 1575 kHz was quite a 'different caliber'.
The same judgment also applies to Denge Welat Kurdish radio on 9530 or
11530_and nearby, or 15175 kHz in signal target.
Now - Iran or Turkey do not nearly reach the jamming level of Bulgarian
or Czech jamming against RFE / RL in that era some 50 years ago.
re 6210/6220 kHz BC usage.
This is a hot game of Armenia or Uzbek RadioCom to install a broadcast
service in this area. A decade ago, all BC users had been warned
by the ITU UN Geneva, and had to clear-up the 6210 to 6400 kHz
marine and maritime frequency range then immediately.
Of course that does not apply to the 'Korea Radio War' therein.
The 1000 Hertz tone play has been happened also in August - September
this 2019 year in 22 meterband in 13500 - 13750 kHz range
by Saudi Arabia vv Iran during daytime hours.
