LF/VLF,I'm doing first local tests in chirped hell by outphasing, i.e. steering the two legs of a H bridge PA with a stereo modulated signal, generated by DF6NMs recently provided program. This is very interesting. Before i apply the signal to a PA (that driver still doesn't exist) i tried just playing in the AF range and record it with SpacLab using the netbooks internal microphone. Besides transmitting letters, i like the option to transmit pictures, which a funny game. See: http://dl.dropbox.com/u/19882028/Outphasing%20tests.png Who is the popular person on the picture? :-) 73, Stefan/DK7FC |
