Now you can listen to the Technet that best suites your needs!

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.080106tech-001 is the first entry in our chart) This means: "This is the January 6, 2008 show, reel number 1" Just click the link!

2. To click reel 2 of the January 6, 2008 show, move down to the next orange box in the same Audio File column which is:
080106tech-001 (which is reel 2 of the January 6, 2008 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 occurrence of that word is shown on the screen highlighted. To find the next occurrence 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.
