Thanks again for posting the recording, John.
Others trying to work SO-67 with handheld stations during passes over the U.S. should try timing their transmissions to coincide with the tail dropping. By doing that, I got in twice, briefly, on this pass between 3:35 and 3:50 into the recording, but not again until more than 10 minutes into the recording, when I worked AA5PK and N5AFV at 1.5 watts on a Yaesu VX-3R and Elk antenna.
73 to all,
Tim - N3TL

Audio for the SO-67 eastern USA pass on 21Nov09 is on my webserver:

Now that it is understood that there is a 3 second tail after each transmission and audio will cut off after that time has expired, ways to get around the problem can be devised.
I found that when called by another station, if you start transmitting before that station releases their transmitter, you will be able to answer and not be cut off after 3 seconds. This is because the "tail" never started. However, if this continuous transmission goes on for 30(?) seconds, the next timer will shut down the transmitter. Waiting for the tail to expire, when the bird is over the USA with many stations trying to get in, will not work. There will always be someone who keys up during the 3 second tail.
Signals were loud as usual right down to the horizon. The extra transmitter power will enable many new users to get on this bird. Thanks to all of those who had a part in launching this satellite!
