[and non]. BBC & VOA English to Africa === The Aoki file posted today, 
June 18, includes many changes showing BBC and VOA English to Africa 
jammed by CNR1 and Firedrake (Dan Ferguson, 1546 UT June 18, NASWA yg

Checking 13 & 16m only so far in Aoki, following as*erisks, these are 
shown as jammed, all English (and sometimes skipping other languages):

VOA:

Please check today, still jammed? These are in addition to numerous 
broadcasts from VOA and BBC to Asia. Also AIR English:
