MHX 2400 DP

For this Cubesat the MHX-2400 spread-spectrum transceiver from Microhard Inc. was to be used and supported by the Cubesat kit. In order to minimize power consumption, +5V power to the modem is under software control from the FM430's Flight CPU.

Due to licenses in the UK and effects of large Doppler shift a 435MHz transceiver is best to be used. This frequency is well suited for the amateur radio band here in the UK.

Having looked into these specifications, here are the technical details for the communications platform of a MHX-2400 DP (Development Platform), available from Microhard Systems, Canada

This includes:

* 2 MHX2400 wireless radio modems
* 2 Development boards
* 2 MCX to RPTNC antenna cables
* 2 MCX to RPTNC 2.4 GHz Rubber ducky antennae
* 2 6' RS232 serial cables
* 2 Wall adapters

Total cost for MHX2400 DP = $1595.00 (CAN)
