Add Bands to your MMX!

If you purchased an MMX Morse Code Transceiver with less then its full complement of bands, you can always add a band board at a later time.

Each band board contains the specialized frequency-sensitive components and control circuitry for the band it was designed to operate on.  The band board is automatically sensed and the band is automatically added to the available bands via the Frequency Button on the Main Screen.  When you select the band for the card, it is automatically connected into the circuitry of the SDR receiver and the transmitter, and ready to use instantly.

Each band board also contains protection components to prevent overload of the final power amplifier (PA) of the transmitter in adverse circumstances.  The protection circuit is automatically resettable in most circumstances.  While it is very unlikely to cause interruption of the ability to transmit on its band due to a failure of the protection components, a backup band card is not a bad idea in cases where getting one repaired is difficult.

Currently available are 80 meter, 40 meter, and 20 meter band cards.
