Friends, Thank you all for your comments and understanding. Please do not use FM on VO-52. There are very few (less than 3-5 radio hams in India who work thru VO-52 on FM due to the lack of all mode 2 meter and 70 cms radios and hence the exception) who use FM when VO-52 is over India. 73's Nitin [VU3TYG] Secretary, AMSAT INDIA
