ADF standby via FSUIPC

[Extraterra]

Hello, I'm trying to set the ADF standby frequency in P3D4. For example ADF2. The normal FSUIPC offset has the problem that it is read only. So I can't use it for setting the value. I am now using the "Radio standby freq ADF2" from Prosim. I entered now an individual offset (in my case 5322) to read out the value. This works but I am still not able to write the value via this offset. The strange thing is, when I trigger the "Radio TFR ADF2" the active and standby frequencies change. So there seems to be a way for prosim to set the standby value. So why isn't that possible via the normal offset way?
Is there a chance to implement this?

I finally found a way around this. If you go away from setting the values directly and concentrate on the encoders, then it works. So now I'm controlling the encoders via FSUIPC offsets and the prosim internal functionality makes the work.
