As other correspondents have noted, Radio Pakistan has shifted all transmissions forward by one hour - presumably as of June 1st.The split frequencies are via faulty 100kW unit API-3, except Urdu at 1915-0045 - now at 1815-2345 - which is via API-4. This unit is used at other times to broadcast domestically the Current Affairs programme, and which should now air at 0100-0300 on 5940 and 1200-1700 on 4835. Other external transmissions are via 250kW units API-5 & 6. The Chinese service now at 1100-1200 has changed frequency from 11570 to 11510 // 9385. World Service in Urdu to West Europe at new time 1600-1800 will need a new frequency on 9 MHZ to avoid a clash with Radio Liberty in Uzbek on 9390 via Udorn at 1600-1700 - as pointed out by Wolfy. 7530 continues.
