!! Protect your Transceiver!!

With this new Soft-Key who safely acts as an amplifier interface between your modern transceiver and the Linear Power Amplifier. This unit is mounted inside the amplifier and transforms the -120VDC key switching, to approximately 0.7VDC at 1.5mA, without it you run the risk of severely damaging the keying circuit in your transceiver.

The switching transistor is in flat position, to install the module in a reduced space, (see pics).

Fully assembled, and tested, no needs other parts, it simply, just install, and solder wires (this module is supplied with welded wires for fast install).

Detailed schematic, parts list, PCB layout, and installation, provided by download in PDF format.

Size: 4 cm length x 3.5 cm width x 1.5 cm high.
