Customer Satisfaction & Support
Customer Satisfaction has been a priority for us since the DG8SAQ VNWA was first launched in 2008
We are keen to ensure that our Customers are able to make an informed choice about their VNWA purchase. Download and try out the DG8SAQ VNWA Software first before ordering.
The VNWA software will start up without the VNWA hardware connected. This allows you to check-out the VNWA features and functionality and assess whether a purchase will meet your expectations.
Every effort is made to make the VNWA easy and intuitive to use for new owners, but be prepared to "invest some time" to get familiar with the many uses and options of the VNWA 3 or 3EC. Take a look at the latest version of the 300+ page VNWA PDF helpfile.
Ongoing Support of all our VNWA Customers
SDR Kits is committed to supporting all our VNWA users, providing technical support, regular software updates and facilitating the DS8SAQ VNWA Forum.
General Software updates for the VNWA 3 and the VNWA 3EC are made available several times a year. The same Software release is used to add new functionality to the VNWA 3 but also to the older VNWA 2.x if this can be supported by the VNWA 2.x hardware.
It is recommended that you become a member of the DG8SAQ VNWA Forum, where VNWA announcements and VNWA user experiences are shared. You will have the benefit of useful information including advice when new software and helpfile updates are available for downloads.
