FM100B • 6
USING THE FM100B WITHIN THE HOME:
A most practical use for the FM100B would be to connect it to the main stereo
system within a large home so that whatever is playing on the main system
can also be tuned-in on portable FM radios in other rooms, the garage or in
the yard. This connection consists of using shielded audio cables to connect
the auxiliary "line audio" output of your cassette deck, CD player or other
stereo device to the audio inputs of the FM100B. Consult the literature that
came with your stereo equipment.
Even if you intend use of the FM100B for your own home and family, it is still
your responsibility (in accordance with Part 15 of the FCC Rules) to ensure
that this operation does not cause interference to your neighbors.
EXPERIMENTAL "BROADCASTING" PROJECTS:
To use the FM100B successfully as a "broadcasting" service to interested
listeners in a school or immediate neighborhood, most of your effort will be
concentrated on smoothly "managing" or mixing the audio signals fed into the
transmitter input. Operation of the transmitter itself consists of the following:
1. Correct construction and adjustment.
2. Carefully checking for an open frequency between 88-108 MHz in
accordance with FCC Rules, Part 15.
3. Setting up a suitable antenna.
4. Connecting the audio source to the Left and Right RCA input jacks.
5. Turning on the transmitter while you intend to be "on the air" and
turning it off when you are finished.
6. For extra protection, use the monitor out RCA jacks to either record
your shows or listen to them on a stereo or on headphones. This will
assure quality sound and transmission. You will need a headphone
amplifier to boost the output of the FM100B to suitable headphone
levels from the line level present at J6.
