Now you can listen to the Technet that best suites your needs!
For the "Power User": Before, you had to flip back and forth between
the "Air date/reel page" and this page
"The Searchable/Index page". Now you can activate each reel right here
- on the same page as the index!
To play a reel on this page:
1. Just click on the bold, underlined link reel, which is always an orange box
in the Audio File column.
(i.e. 060910tech-001
is the first entry in our chart) This means: "This is the Sept. 10, 2006 show,
reel number 1" Just click the link!
2. To click reel 2 of the Sept 10, 2006 Show, move down to the next orange box
in the same Audio File column which is:
060910tech-002
(which is reel 2 of the Sept, 10, 2006 show).
Don't forget to use your player's EQ to taylor the sound!
To find a topic: Right now I have the "poor man's way" to search for
topics. In this browser window, go to the Edit Menu
then Find On This Page
(CTL-F). A dialog box appears- just type in a term that matches your topic, then
press return.
The first occurance of that word is shown on the screen
highlighted. To find the next occurance of your term press the "Next"
button.
I understand this is a very crude way for searching, hey, it's better than
nothing I guess. In the future I will be installing a
Google-like search
feature for amateurradio.tv.
