saan project 'to? depende 'yan sa frequency, layo ng transmission, at orientation nila.

I would suggest na gumamit ka ng mas mataas na frequency sa carrier para hindi kayo mapagastos at mahirapan sa paggawa ng antenna..
take note: antenna size is dependent on frequency.. mas mataas ang frquency, mas maliit yung size ng antenna..
saka consider din natin yung "distance", from mother RDPZYCH, :-) yung distance, iassume ko na din na short distance lang yan kasi kelangan nyo itest sa shool yan, kaya malamang low power lang magagamit nyo..
For the antenna, you can use yagi-uda antenna.. simple to build, reliable and kayang kaya ng budget...
suggestion lang to ha.. if you can think of any greater idea to improve your project, pwede mo i-incorporate..
good luck!!

samin dati ginamit namin 150MHz tapos transmit namin using handheld radio... kinabit namin sa SWR meter para makita yung mismatch.. eh 1.2 lang swr nya kaya OK na daw yun... gumawa kami 3 stack dipole...

Markie, tama si sister nucleus, Yung project nyo is nothing more than a stereo transmission na may left and right channel. Yung stereo FM transmittter sa CDR King binanggit, pwede yun at di nyo kailangan ng dedicated RX dahil any stereo FM radio will do. plus, you can manipulate the frequency to outside the 88-108 commercial FM broadcast.
