Dear Gerald, I have the sense that software improvements is a commitment from FlexRadio and it is included in your old motto: "The radio that keeps getting better". > With regard to RX and TX image calibration by band, the FLEX-5000 has built > in test equipment (BITE).

The least one needs is just a second tranceiver and the permission from the software (PowerSDR) to let you store different settings for each band.
