Frequency Change - Blank CDU

[Gabreil]

With the current CDU problem with it going blank on certain key presses -  Its somewhat of a challenge to change the Frequencies for SRS.  I want to set UHF 250.000.   I
Or, Is there a .lua that can be edited so it always powers on on a desired  frequency - again in my case 250.000

Thanks as always.

You can set the FRQ on the Mission page of the CDU.

I did try that.   Not sure if it was something in the way i was doing it..  After selecting the radio, then freq preset followed by  pressing tune it did not change on the MFD to the selected frequency.

I did find an answer to do it via the CDU:

CNI > Radio > Presets (when screen goes black) Type Freq you want (250) > Top Right Arrow > Top Left Arrow > CNI.

Not on the MFD, but on the CDU. I can't tune presets on the MFD either.
