Dear Flexers, I thought it would be in order to give the reason for updating the calibration of RX2 after installation of the new firmware/PowerSDR update. We made an improvement in the accuracy of the local oscillator (DDS) quadrature phase setting on RX2 with this release. Because of this change, it is necessary to run the RX2 calibration as Dudley noted. There is no change to RX1.
Note that this firmware release also improves CW transmit to receive recovery by turning off the transmitter local oscillator when in receive mode. Beta testers have reported significant improvement in this area.

I did notice that you should reboot the computer and power down the radio and back up before running the tests.. 73, Dudley WA5QPZ Dudley Hurry wrote: > PowerSDR V1.16.1 is now available on the home page and works with the > updated firmware of 1.3.0.0 for the Flex 5000 series.
