Good VHF Tropospheric Propagation

Today the VHF Propagation was so good that I was able to work with the Kodaikanal (VU2KOD at 300kms) and Nelliampathy (VU2BCM at 285kms) repeaters from Bangalore.

This is clearly a "Tropospheric ducting" propagation where the signals are refracted back to earth. This seems to be a regular phenomenon in South India especially found during this time of the year (feb).
