The National PSK Preselector was specifically designed for the National FB-7 series of receivers, but could be used for any TRF or superhet. It utilizes a single plug-in coil for each band, covering 0.9 MHz to 34 MHz. It could be run as a 2.5 or 6 volt unit, depending on which tube was used. The PSK can be run from the same power source as the main unit or from a separate power supply.
