You cannot legally operate the aircraft radio without both RTR and FRTOL valid
The DGCA wont endorse a type rating if the RT license is not valid
If you have 30 hours of flying experience within the last 3 years you can submit for renewal and get a lifetime validity ( i am guessing you got the RT license after passing part 1 and part 2 )
Otherwise you need to pass Part 1 again and then you can renew for lifetime . The last date for the October attempt is over . You can give the December attempt in Hyderabad
