New Software for JT-65 and Fun with interfacing computers and ham radio.

JT-65 is a wonderful way to make radio contacts using a ham radio with computer, interface and software. The fun part is you work with low power.  You would be surprise how far a 10 watt JT-65 signal will travel.

This protocol is much like playing ping pong.  You must set your computer time to the second to ZULU time before you begin.

Here is the Zulu clock that I use: http://zulutime.net/

Here are some video demonstrations:

The man doing the demonstration mentioned an unwritten rule about a 5 watt max.  I have not heard of any such rule.  I have made contacts all over the world with power setting from 10 watts to 25 watts.
