Subject: [bdxc-news] Radio Afghanistan International - 7600 kHz
The switch between transmitters for London-based Radio Afghanistan International on 7600 kHz appears to be at 1600 UTC at present. It is heard on 7599.9 kHz or thereabouts (presumably from Tashkent, Uzbekistan) until 1600, from when it also appears on 7600.0 kHz (presumably from Yerevan, Armenia), with any trace of 7599.9 disappearing soon after. It's listed as a 24 hour schedule on their website for 7600 kHz, and I’m assuming it changes back from Yerevan to Tashkent at either 0100 or 0200 UTC. I briefly checked at 0245 and it was seemingly back on 7599.9 by then, but I could be mistaken. Monitored using the KiwiSDR in Novosibirsk, Russia. 73’s Tony
