Spektrum AR9000 9 Channel
2.4GHz DSM2 Receiver

AR9000 DSM2 9-Channel Receiver (SPMAR9000)

By combining two internal, alongside one further remote receiver, the AR9000 has the capability of performing the most sophisticated monitoring of the RF environment yet seen in aero modelling to date. In addition one remote receiver can be added to increase that capability even further.

Spektrum radios simultaneously transmit on two frequencies and this combined with multiple receiver locations result in unmatched monitoring of the RF environment providing optimum path diversity and a more secure radio link.

This option is particularly useful in large scale aircraft and jets where remote receivers can be easily sited around the plane to increase the RF ‘eyes’ of the system and avoid the kind of problems encountered with installation of more conventional systems. To facilitate the sheer physical size of some of these planes remote receiver extension leads for the remote receivers are available in 150mm, 230mm, 305mm,610mm and 915mm lengths.

The Spektrum Flight Log (SPM9540) is compatible with the AR9000 receiver. Whilst the plane is being flown it logs data about the overall performance of the RF link as well as individual data from the main and remote receivers. Once the plane lands this data can be reviewed and used to optimise the receiver installation. It also gives an indication as to the level of 2.4GHz “noise” present in the flying environment, and displays the receiver voltage so you can be sure that power capacity is sufficient for the next flight.

Neither the Flight Log or the optional remote receiver are actually essential for the AR9000 to operate but with more complex models they can be of great benefit. All models are different, and each can present unique problems which customised radio installation, assessed by hard data can help to eliminate.
