IRIB vs. Iran International TV audio on 11590/6210/6220 kHz

IRAN   IRIB vs. Iran International TV audio on 11590/6210/6220 kHz, November 20
1000&1130 on 11590 Sirjan? vs. Yerevan? to N/ME Arabic/Persian IRIB+Iran Int.TV
1130-1200 on 11590 Sirjan? vs. Yerevan? to N/ME IRIB test tone + Iran Inter.TV
from 1200 on  6220 probably via Yerevan to N/ME Persian Iran Inter.TV + STANAG
from 1205 on  6210 probably via Sirjan? to N/ME IRIB test tone 1000 Hz & continues at 1320UT

from 0835UT both VIRI IRIB & Iran International TVare on 11590
from 1130UT on 11590 VIRI IRIB with TEST TONE & Iran International TV in Farsi
from 1210UT test tone on 6210 kHz, 11590 is off
from 1430UT on 6210 Sirjan test tone 1000Hz


At 1455UT  the "test tone" is audible on 6210 - very strong and no trace of any audio. The same at 1500+. My guess is that the tone is a jamming signal, particularly as it went off 11590 about the same time as the transmission on that frequency in Farsi. If  6220 is still on air it's inaudible here due to the strong STANAG transmission at 1500. (Noel R.Green, NW England)
