FM Radio in Assam

Now-a-days, I'm getting loud & clear signal specially in the morning,late afternoon to night of all three private FM Radio Stations i.e. Radio Ooo Laa Laa on 91.9MHz, Big 92.7 FM on 92.7MHz & Radio Gopshop on 94.3MHz broadcasting from Guwahati City in my place ,Abhayapuri on Western Assam (approx.170-200km Airal distance range from Guwahati City ) via my Grundig Yatch Boy 400 Receiver (Digital) with telescopic Antenna.
Also a FM Radio Station transmission from Bhutan on 90.00MHz can heard loud & clear here. The FM transmission of All India Radio Guwahati on 100.8MHz can be heard here also. Also FM Relay of All India Radio Guwahati etc can be heard from All India Radio's Dhubri FM Relay Transmitter on 103.3MHz loud & clear sometime even during day time also. I also heard a few months back All India Radio FM Rainbow Relay on 103.6MHz from AIR Shillong. But now-a-days, the signal is not audible here.
Gyan Bani relay from Guwahati on 107.8MHz::
On October 4,2007 around 0143UTC heard Gyan Bani Guwahati on 107.8MHz with fair to poor signal. There was station promos plus other educational programs. Gyan Bani is educational FM channels run by IGNOU.
On October 5, I got good signal of Gyan Bani Guwahati around 0100UTC. There was program on Sri Sri Sankar Dev, the great Basinav Guru & his disciple Sri Sri Madhav Dev , their life & legacy & works & cultural contribution-devotion songs etc in Hindi.
Gyan Bani uses All India Radio's FM Transmitter facilities in various locations.
