** INDIA. INDIAN TIME STATION ATA CEASED SW BROADCASTS

Dear Friends, My investigations has confirmed that the Standard
Time and Frequency transmissions by Station ATA, National Physical
Laboratory, New Delhi has ceased its SW operations about 3 years back.
They used to operate on 5, 10 and 15 MHz with 2 x 8 kW from Greater
Kailash, Delhi.

There were voice announcements by male in English every 15 minutes
with station identification and IST. Ionospheric data was given every
hour.

Since 1988, NPL has been transmitting Standard Time and Frequency
Signal via INSAT satellite. It is also available via telephone now.

They used to issue QSL confirmations for their SW broadcasts and I
have 2 in my collection. One is in letter form and other one is a card
which was issued in 1978 by them after getting "inspiration" from
Dr. Adrian Peterson of AWR. They issued that card after a special
station profile on that station was broadcast by him in Radio Monitors
International via SLBC, Sri Lanka.

More details about their present activities is available from
