An open-ended set of extension parameters and levels are available for each amplifier, as provided in the amp_caps::extparms and amp_caps::extlevels lists. These provide a way to work with amplifier-specific functions that don't fit into the basic "virtual amplifier" of Hamlib. See amplifiers/elecraft/kpa.c for an example.
