(front living room, garage, deck) and have someone else turn up the power
until you receive the signal clearly. Stop adjustment right at this point; this is
as far as you will need to go! You may be surprised by how little power you
really need. If you have to run it at full power you may need to play with the
antenna a bit because that may indicate that you don’t have a good match.
The last setup screen allows you to save all of your changes. Pressing the
[UP] button will save them to the internal FLASH memory; [DOWN] will con-
tinue to use the current settings, but will not save them to FLASH in case you
need to make some more changes. Cycling through all of the displays again
will get you back to this screen to save all of your changes.
USING THE FM30 WITHIN THE HOME
Typical use for the FM30 would be to connect it to a personal computer within
a large home so that whatever MP3 or other audio files are playing can also
be tuned-in on portable FM radios in other rooms, the garage or out in the
yard. The provided whip antenna should cover a typical home’s boundaries
quite well. An external antenna can be used for a larger coverage area if de-
sired. Use the RF adjustment control to fine tune the RF output level to just
reach the area you intend to cover.
The audio connection consists of using shielded audio cables to connect the
line or speaker level output to the audio inputs of the FM30. Consult the litera-
ture that came with your stereo equipment.
Even if you intend use of the FM30 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 FM30 successfully as a "broadcasting" service for interested listen-
ers in a school or immediate neighborhood, most of your effort will be concen-
trated on smoothly "managing" or mixing the audio signals fed into the trans-
mitter input. Operation of the transmitter itself consists simply of the following:
1. Correct construction and adjustment.
2. Carefully checking for an open frequency between 88-108 MHz in accor-
dance with FCC Rules, Part 15.
3. Setting up a suitable antenna.
4. Connecting the audio source to the input jacks.
5. Turning on the transmitter while you intend to be "on the air" and turning it
off when you are finished.
The more home-built your complete setup, the more it is in conformity with the
spirit of FCC Part 15 regulations.
