This morning I spent about 45 minutes listening to the unidentified middle eastern station on 13790 kHz that I think is probably the Voice of the Islamic Republic of Iran (VOIRI). Time: 1345-1425 UTC. Fair to poor signal. Middle eastern music, then western musical interlude. Talk in Arabic, including an interview. Heard a couple of mentions of Iran but no ID. Off air at 1425 UTC. Matches program times and description in WRTH 2011 for VOIRI, which is scheduled on this frequency at this time in Arabic, with a power of 500 kW.
Since this station is weak but shows up regularly I`m confident I`ll get an ID sooner or later.
