The Sparton model 105-X receives most probably the following bands: Broadcast 550 - 1500 kHz and the SW bands 1.4 - 3.4 MHz, 3.3 - 8 MHz and 7.5 - 19/20 MHz. The VisoGlo tuning indicator VG-1 is extremely rare, even in the literature it is nearly not noticed. The model 104 and 105-XS use the same tube line up.
