— Besides the remote controller, HV-122 can be configured and controlled thru its UART port by an external host.HV-122 can also decode the mux'ed UART data in received streams and output it thru its local UART port. - 14 Channel bandwidth
— Besides standard TV channel bandwidth (5/6/7/8MHz), HV-122 can tune 1/1.5/2/2.5/3/4 MHz bandwidth channels. - 15 Band options
— Depending on the model options, HV-122 supports standardTV-band (170-860MHz ),2.4G-band (2100~2550MHz), or All-band (170~2700MHz).

- There is a saw filter in the RF front end. The saw filter limits the reception range but minimize ACI (adjacent channel interference).
- When the saw filter removed, full band range is supported but poorer ACI. The sensitivity is ~20dB less at 170~700MHz.
- Specifications are subject to change without prior notice.
