Abstract:
A RACAL-17L communication receiver is used to record signal strength at Ahmedabad on 11.8 MHz transmitted from Colombo.
In the initial stages of the eclipse and again towards the ending phase the signal strength showed large undulations comapared to control days.
During the main phase of the eclipse (07:40 to 08:50 IST) the undulations were not there. The signal strength continuously rose from 07:40 IST till maximum of eclipse (8.30) and later it continuously decreased up to 08:50.
On the eclipse day increased fading in signal strength with regular wave like appearance persisted even during late night hours from 19:00 to 22.00 hrs. with a time period around 24 minutes.
