You can get an RTR license on the basis of just operating a radio . You can only renew it
@hemlohani07
If you have 30 hours of experience as an RT operator within the last 3 years then you can renew it for lifetime by paying the 10,000 rupees DD
Other wise you need to pass part 1 exam again and pay the 10,000 rupees DD and get it renewed for lifetime
@boeing787dreamliner
In order to renew the Indian RT you need to pass part one as well as hold a valid Philippine CPL
I am not sure if they will accept the part one results from 3 years ago , you will have to check with someone in Sanchar Bhawan regarding the same
I strongly recommend applying for the next attempt in Delhi , Pass both Part 1 and Part 2 and then apply for the RTR A license with lifetime validity . That way you wont have to worry about renewing the RT license ever again
