Radio Operation
| | Learning about your receiver
 |
The Receiver Team's job is to understand how the FM radio
in your observatory works, including the
connections on the back and the settings controlled from the front panel. They
must work with the Software Team to ensure the |
receiver is connected to the sound card of the
recording computer and with the Antenna Team to ensure the antenna is connected
correctly. Follow the link at the left to see how to operate the radio itself.
The team should do the following tasks:
 | Learn what the frequency ranges are on
the FM band that are clear of local radio stations. For example, you might find
that there are no radio stations that can be heard between 88.1 to 89.5 on
the radio. Note the beginning frequency (eg 88.1) and the last frequency in
the band that is clear from the bottom to the top of the FM band. |
| Listen to the AM band on the radio, searching from the bottom to the top
of the band and note the frequencies that have radio stations on them. Note
any characteristics of the band that you hear (static, smooth, stereo,
etc.). |
| Do the same observation of the FM band, noting the sound characteristics
of the band and how it is different from the AM band. You can do this at the
same time you are scanning the FM band for clear frequencies. |
If you have already done these exercises as part of your homework, then use
the results of your homework to compile a list of characteristics of both bands,
and identify clear frequencies on the FM band.
