The 6600 and the 6600M both share the same game-changing band awareness, industry-leading phase noise performance/receiver dynamic range, and brick wall filters to give you the advantage in the most competitive DXing or contesting activities. With a PC, laptop, or Mac client, you can utilize up to four 14 MHz spectrum/waterfall displays and independent band/ mode receivers to revolutionize your view of the bands, especially on digital modes.
