2000 W in RTTY, AM and FM
Driver Power:40 to 60 W for full Output Power
Input impedance:50 Ohm VSWR < 1.5 : 1
Output amplification:17 dB
Output impedance:50 Ohm unbalanced
Maximum output SWR:2:1
SWR protection:automatic switching to STBY , when reflected power is 350W or higher
Intermodulation distortion:32 dB below nominal output
Suppression of harmonics:< -50 dBc
Tube:GU84b Ceramic tetrode
