Find Transmitters
Try the following sources of transmitters:
- The tuner's Hot page is a list of channels chosen by Marimba;
the list is updated with the tuner each week.
- The Marimba button on
the tuner's Marimba page shows you the Marimba transmitter's
channels.
- The Marimba
Channels Web page
is another source for channels.
- The
Gamelan
Java directory has a list of channels under the heading Related
Technologies: Castanet Channels.
- The
excite
Channel Guide is a channel that describes other channels.
Subscribe to a Channel with the
Tuner
- Click the Listing tab.
- If the channel's transmitter is not shown in the scrolling
list or the drop-down list, type the transmitter's name in the
text field, then press Return/Enter.
Note: If the transmitter does not listen to IP port 80, append
a colon and the port number to the name, for example,
"trans.havefun.com:5282".
Note: On the Solaris platform you can enter an IP address
instead of a transmitter name.
- If the transmitter is shown in the scrolling list, but the
channel you are looking for isn't, select the transmitter, then
click Refresh to update the transmitter's channel list.
- Double-click the channel.
Subscribe to a Channel with a Web
Browser
- Visit the channel's transmitter's Web page. If the
transmitter's name is trans.marimba.com, the URL to type into the
Browser is http://trans.marimba.com.
- Click the channel link.
Unsubscribe to a Channel
- Click the Channels tab.
- Find the channel's transmitter and click its + if necessary to
show its subscribed and unsubscribed channels.
- Select the channel to be unsubscribed.
- Choose Channel:Unsubscribe.
Note: unsubscribing removes the channel's code and content
files but not data files it may have created (such as documents or
preferences). If you re-subscribe, the data files are still
available. To remove the data files as well,
remove the channel.
Remove a Channel
- Click the Channels tab.
- Find the channel's transmitter and click its + if necessary to
list its subscribed and unsubscribed channels.
- Select the channel to be removed.
- Choose Channel:Remove (that is, choose Remove from the Channel
menu).
Note: removing a channel destroys the channel entirely: its
code, content, and any files you created with it.
Resubscribe to an Unsubscribed Channel
- Click the Channels tab.
- Find the channel's transmitter and click it's + if necessary
to list its subscribed and unsubscribed channels.
- Double-click the channel.
Note: Any files you previously created with the channel are
available after you resubscribe. Resubscribing downloads a fresh
copy of the channel's code and content.
Update a Channel
- Click the Channels tab.
- Select the channel entry.
- Choose Channel:Update.
Note: Some channels respond to updates while they are running;
others reflect updates the next time they are launched. Consult
the channel's documentation for details.
Start a Channel from the Tuner
- Click the Channels tab.
- Double-click the channel entry.
Stop a Channel from the Tuner
- Click the Channels tab.
- Running channels have a Status of "running"; double-click the
channel entry.
You can also stop a channel by clicking its Close box (X in
upper right corner of window).
Update the Tuner
- Quit running channels. (If you don't, the tuner will ask you
if it can quit them for you.)
- Choose Tuner:Update Tuner.
Note: The tuner is automatically updated weekly.
Abort a Tuner Download
- Choose Tuner:Cancel Transfers or type Ctrl-c.
Learn When a Channel will be
Updated
- Click the Channels tab.
- Select the channel.
- Choose Channel:Properties
Note: The Update Active value (never, 15 minutes, hourly,
daily, weekly) specifies the update frequency for the channel when
it's running. The Update Inactive value specifies how often the
channel is to be updated when it's not running. Interpret these
values as the frequencies requested by the channel developer.
Values you provide on the
Configure:Loading
page can reduce the actual frequency of automatic channel
updates.
Limit Automatic Updates
- Click the Configure tab.
- Click Loading.
- Choose a value from the "Automatic updates can be made"
drop-down list to limit the time of day during which automatic
updates will be made. Choose "Never" to disable automatic
updating.
- Choose a value from the "Frequency of automatic updates"
drop-down list to limit how often the tuner will check for
updates.
- Click Apply.
Note: A channel cannot be automatically updated more frequently
than its developer requested (see the
channel's Properties page). You
can manually update it whenever you like, though updating a
channel more often than its developer specified may not be
fruitful.
Create a Windows Shortcut for a
Channel

- Select the channel.
- Choose Channel:Create Shortcut.
Prevent Channels from being
added to the Windows Start Menu

transmitter channel

usr/local/castanet/tuner/bin/tuner -start www.marimba.com

quotes.
