I have named it Jason, from the name of the coxswain of the mythological ship Argo, which was headed to Colchis by the Greek hero Jason. The coding scheme of Jason is based on the ideas about IFK that can be found on the Web site of Steve Olney, VK2ZTO. I need your cooperation to test it. I have done some preliminary tests, which have given very good results, but a true test on the LF hasn't been performed yet. Instead of cluttering this reflector with the gory technical details of Jason, I invite you to visit this page : http://www.weaksignals.com/jason You can use Jason with a mosfet Class-D Tx, no need for a linear amp. You can drive the Tx either using a DDS board connected via the parallel port or the serial port, or up converting an audio signal generated by Jason. I tested only the audio interfacing. I need someone who volunteers for testing the interfacing via the DDS board (I haven't one), with true on-the-air tests. Thanks for any cooperation 73 Alberto I2PHD
