Dr Rego

There are two possible problems. One is that your own transmitter is not generating sufficient EIRP, which could be due to an antenna mismatch. The second, and more likely, is that other stations nearby are generating spurious signals at your allotted frequency band. As you report, they 'invade' your space. 

According to you, 'checking' for the cause only got you the answer 'frequency' - who gave you this answer? If it is anyone from the Ministry (telecom or broadcasting)/WPC, then perhaps you need to file an RTI asking them for copies of orders given to the other stations to repair their setup. 

It would also be useful to track the actual status of transmission during your broadcast timings, and also at other times, in order to establish whether your bandwidth is being cluttered by spurious signals from other nearby stations. Finally, is there a chance that you are located too close to the transmission towers of any other stations? The SACFA clearance was supposed to take care of this aspect, of course.

Subject: [cr-india] on frequency

Hi everyone!

I have a problem. Would like to know how you would deal with this - we have 107.8 MHz frequency assigned to us. But low power radio sets and mobiles cannot receive our radio signals even in nearby areas - car stereo do. That means, local communities are deprived of our transmission. People keep pleading us "increase signals" - they have listened to our station sometime; they have read in newspapers. hence their demand. We are unable because of the frequency.  We checked why this happens. The answer is 'frequency'. In addition - noise!

Besides, private FMs and AIR keep invading our frequency gloriously. All Our efforts and people's desire doesn't seem to be bearing fruit.

How would be address this problem? 
I will try uploading an audio piece recorded from our own transmitter in our own campus & in the vicinity of the College. You can feel the noise and difference.

If I succeed, the piece should be available through my blog www.richardrego.wordpress.com for you to get a taste.
