Yes, this has already been submitted to the developers bug tracker for improvement in the execution of the RX Image rejection calibration process.

Tim If it is best that the antennas be disconnected - then should there not be a pause in the set procedure to allow them to be disconnected? Perhaps (for my setup) it's not that important but I'm guessing that we all would like to have the "system" running the best that it can. So if I uninstall PowerSDR, disconnect the antenna's and reinstall - would that work better, without the risk of the manual system?

Here is the procedure to run it manually, but you should only do this if you are experience SEVERE issues with image rejection. Don't use the lower half of the bands in a CW contest to determine if you have a RX image rejection problem. WBIR is not working 100% correctly yet and there are too many strong signals down there to null properly. > > Caution: Running any other calibration test other than the ones > described below may hose up your radio to the point it may have to be > sent to Austin to correct and it may not be covered under warranty > repair, meaning you might have to pay bench rates for the fix. > > Procedure: > > If you have PowerSDR running, do a database reset using the Setup form > (buttons at the bottom).
