The LDG AT-600Pro2 closes the gap for mid-range power levels. The tuner allows a maximum power on shortwave (1.8 to 30MHz) of 600W in SSB and CW, max. 300W in RTTY. On 6m (50 to 54MHz) a maximum power of 250W is possible. The AT-600Pro2 uses the proven LDG switched L network, controlled by a micro processor. This results in automatic tuning within a few seconds. The matching ranges from 6 to 800Ω on shortwave (16 to 150Ω on 6m). This corresponds to an SWR of approx 10:1 which is transformed to approx. 1.5:1.
