My native town is Porayar (Nagapattinum district of Tamil Nadu). But now I am in Karaikal. When I was there in Porayar (1996, 1997), I used to get Only DD National and DD Podhigai in one single channel from DD's terrestrial relay station located in Karaikal.
Apart from that, I used to get around 10 or 15 channels from Sri Lanka. Most of them were in Sinhala and few Tamil and English Channels.
Sakthi TV (Tamil) - Used to re-telecast programs from SUN TV. Later had their own programs and few from Sun TV.
Sirasa TV (Sinhala and part time Hindi)
Channel 1 (English)
Swarnawahini (Sinhala, part time Tamil and part time Hindi) - Used to re-telecast ATN (Hindi) and Raj TV (Tamil) programs. Used to telecast latest Tamil and Hindi movies before Indian channels telecast them.
Rupavahini (Sinhala, Tamil, English)
Rupavahini-I (Sinhala, Tamil, English)
E-TV (English)
and many other Sinhala channels (don't remember the names now
)
