| Abstract: | A critical examination is made of records of some experiments that were made in 1980-81 to find out if spread-F could be produced by high power short wave broadcast transmitters modifying the F-layer. The heating transmitter of 250 kW was at Aligarh and the monitoring ionosonde at Delhi. It is concluded that, with transmitter power of the above order, enhanced spread-F condition may be produced if some irregularity structure is already present in the F-Iayer and also if the heater frequency is within about ±0.1 MHz of ƒ0F2. |
