IF Output Modification
Basic Information
This modification provides a tap of the Jupiter's internal 12KHz IF at a connector on the rear panel of the radio. This is intended to facilitate reception of Digital Radio Mondiale (DRM) as well as other, future digital-mode broadcasts.
Contact John W3GQJ directly for information about his success and comments about the excellent quality of his DRM reception using the Jupiter 12Khz IF feed.
