Standard free-to-air (FTA) set-top boxes (STBs) and early versions of the MiniTiouner using the Sharp tuner module, only cover the frequency range 650—2400 MHz. Whilst this is fine for the 23cms (1.3 GHz) and 13cms (2.3 GHz) amateur bands it does not provide coverage of the 146 MHz (2m) or 437 MHz (70cm) bands, where the majority of ATV operation takes place.
In order to provide coverage on these lower bands we need to use an upconverter in front of the tuner which converts 146 MHz or 437 MHz up to an L-band frequency that is within the coverage range of standard FTA STBs and early MiniTiouners.
The page list details of receive upconverters used to convert 146 MHz or 437 MHz ATV signals up to L-band:
- 146 MHz to L-band receive converters:
- 437MHz to L-band receive converters:
SUP2400 mods - 70cms to L-band receive upconverter hardware modifications
SUP2400 DiSEqC - 70cms to L-band receive upconverter DiSEqC control PCBs
