From The RadioReference Wiki
The RadioReference Wiki has some custom extensions. Many of these can be used to display dynamic data in the database of custom pages of information. They are currently as follows:
Contents
Displaying Conventional Frequencies
You can display conventional frequencies stored in the database with the following tag:
<freqsubcat>xxx</freqsubcat>
Where:
xxx = The Frequency Subcategory ID
To find the subcat ID, click on the page symbol with the small circle next to it, and the following results:
Displaying Frequencies for a Trunked System
You can display the frequencies for a Trunked Radio System in the database with the following tag:
<site>xxx|yy</site>
Where:
xxx = The Trunked Radio Database sid number yy = The system's site number
To find the "sid" for a trunked system, look in the URL for each trunked system entry:
Determining Trunked System SID
The site number is shown on the far left column of each row of trunked system frequencies under the column named 'site'
Displaying Talkgroups
You can display the talkgroups for a Trunked Radio System in the database with the following tag:
<tg>xxx|yyyyyyyyyyyy</tg>
Where:
xxx = The Trunked Radio Database sid number yyyyyyyyyyyy = The talkgroup group name
The SID is found using the method above. To find the group name, go down to the desired talkgroups and point at the page symbol with a small circle next to it. The following display results:
Click on it, and the following image results. The group name is at the top, category ID below it
Displaying Recently Updated Frequencies and Talkgroups
You've submitted changes to the database, they've been entered - why can't I see the changes on the Wiki?
The reason is that you are getting your old page from the Wiki's page cache. What is needed is to clear the cache, so the Wiki is forced to rebuild a new article, and the extensions will pull the updated information. To do this, add the statement ?action=purge to the end of the URL, then press enter.
It's recommended that all articles that use the extensions to pull frequencies and talkgroups add a link at the bottom of the article for this purpose. Using the <small> tag will keep it out of the way of the rest of the details. For example
<small>[http://wiki.radioreference.com/index.php/Andrews_Air_Force_Base%2C_MD?action=purge Refresh] this page from the latest database entry</small>
Displaying EBay Search Results
You can display Ebay search results with the following tag:
<ebay>Your Search Here</ebay>
This extension is helpful for displaying used equipment on many of the equipment pages.
