Power Amplifier for 136kHz 1kW
The design is somehow up-side-down. It is because the power FETs are mounted on the heat-sink which is on the top of the box

136 kHz Transmitter JUMA TX 136
JUMA TX136 is a digitally controlled CW transmitter for 136 kHz (2200 meter) amateur radio band. The transmitter is available as a component kit which inludes all the electrical and mechanical componets

136 kHz
UK Radio Amateurs received permission to operate on the new 136kHz band (135.7-137.8kHz) in February 1998

136kHz Activity
Canadian amateurs have full access to the 2200m and the to 630m bands without the need for special operating permission
