My SR-447HPC2 isn't showing the SWR when I transmit.

The feature can be turned on or off in the radios programming. From the factory, this feature is turned on, but can be inadvertently turned off if a dealer performs a reset procedure. The programming software for the SR-447HPC2 will be available this month if you'd like to turn the feature back on. If you are willing to send your radio to us, we can do the programming procedure for you. If you'd like us to do it for you, please visit repairs.strykerradios.com and submit an RMA request.
