Transverter

Some transceiver manufacturers are supportive of add-on transverters, and design in circuitry and cabling attachments for them.

Several low frequency bands are available around the world to amateur radio operators, licensed experimental stations, and some unlicensed hobbyists.

Historically "transverter" was the name for an electromechanical device, invented in Britain in the 1920s, to produce high-voltage direct current from AC sources for efficient power distribution over long-distance lines.

By automatically analyzing and converting the power between different voltages and AC or DC, the transverter enables energy to flow between all types of devices.

Transverters also locally correct for power factor, which creates significant reductions in transmission loss for the grid.
