2.4 About the Software with your AXRX-QDM Receiver
The AXRX-QDM Receiver has two software elements:
Firmware that operates on the primary board of the device.
Control Application that you operate on your Windows PC.
About the Firmware
Although much of the unit is built up of hardware components, many of the sophisticated
features are done in the firmware operating on a Field Programmable Gate Array (FPGA) in
the device.
When you must do an internal software upgrade we can give you an installer which contains
all the code to do this easily.
About the Control Application
The software tools give users with a convenient access to the most usual features and
functions of the Device. All software tools are implemented as a web interface. The
advantage of a web interface is that it is independent from the user’s operating system and
it is not necessary to have special software on the host PC.
The computer display control application of the unit gives access to many of the features of
the radio but for more sophisticated operations and configuration tasks you’ll connect up a
PC operating a web browser to access the Control Pages on your AXRX-QDM Receiver.
The Control Page enables you to set up sixteen presets in the radio and have control of
many parameters of the unit.
Here’s what the receiver’s Control Pages look like:

Keep in a cool and dry environment. Being kept too hot can cause permanent loss of
capacity.
For short term (fewer than six months), keep in a fully charged condition.
For extended periods (more than one year) charge before keeping and charge at
intervals of six to nine months.
Always fully charge the battery after a period of more than one month before operation.
Do not keep the battery with the charge low as this can cause the battery to become
unserviceable and invalidate the warranty.
Do not short circuit.
Do not put in water.
Do not burn. Cells are likely to explode if put in a fire.
Dispose of batteries in accordance with the regulations for the Country of operation.
Batteries are usually thought of as ‘isolated waste’ and must not be in the usual waste
stream. Send to the seller, or send to an approved re-cycling company.

F Means…
FEC Forward Error Correction is a system of error control for data
transmission, whereby the sender adds redundant data to its
messages, also known as an error-correction code. This lets
the receiver find and correct errors (inside some bound) without
the need to ask the sender for additional data. The advantage of
forward error correction is that a back-channel is not required, or
that retransmission of data can often be prevented, at the cost of
higher bandwidth requirements on average. FEC is thus applied in
situations where retransmissions are relatively costly or
impossible.

the less obtrusive the background noise is.
Shannon Limit The Shannon limit or Shannon capacity of a communications
channel is the theoretical maximum information transfer rate of

Signal In electronics, a signal is an electrical current or electromagnetic
field used to send data from one area to a second area. The
simplest type of signal is a direct current (DC) that is switched on
and off; this is the principle by which the earliest telegraph
