Transceptor FLEX 6700

SmartLink™ for Remote Access

The FLEX-6700™ is for the most demanding amateur radio operator who desires the ultimate on-air experience.  With dual spectral capture units (SCUs), the FLEX-6700 allows multiple active antennas providing reception and unprecedented spectrum visibility across up to eight panadapters and waterfalls. The FLEX-6700’s dual-stage RF preamplifiers enhance weak signal reception up through six meter and two meter bands*.  Total flexibility and the highest performance sets the FLEX-6700 apart from other radios.

*Two meter transmit power limited to -15 to +7 dBm; external power amplifier not included.
