I guess you have registered for the necessary
license from the authorities in Jamaica?
They will have a frequency listing for
Studio-Transmitter broadcast links.
Then you need
to look around for suitable low-power transmitters
and receivers for those bands.
The distance from
your studio to Tx site is short, but rainfall in
Jamaica is high at peak times in the wet season.
So look for channels around 900MHz, and look out
for a shrouded yagi with a gain around 10dB, eg from
Another solution might be to lease
a DSL line or ISDN circuits from the PTT. Assuming
they offer you high reliability, that might be
cheaper and give you a better overall quality. I
know a commercial FM station owner in Germany who
has leased 2xBRI ISDN circuits from Deutsche Telekom
to do this link. Although 1xISDN (Right stereo) +
1xISDN (left stereo) at 64kbps each (ie BRI ISDN)
was not enough bandwidth, he rented 2 ISDN BRI
circuits at 128kbps each, and used one for the Left
channel, one for the right channel, and used the Q
channel at 9.6kbps for the station control data
