Thank you for answering. By the way, you should not be sorry for delay in replying, holidays are legitimate. I found 2 cases: 1. starting from 1600.0, writing 1700.0 has no visible effect on the panel, readback through FSUIPC shows transiently the written value, then the original value. 2. starting from 0100.0, writing 1700.0 makes the panel display 1100.0. Unfortunatly, no valuable result. Since you had already identified the bug, I think there is not much to do with it, and honestly, I am not sure it is worth spending much effort on the topic. As for me, I'll set wrap-around at 1600.0 and forget supporting higher frequencies. Thanks again, Daniel Delande

I am currently writing an application that drives NAV settings. FSUIPC version is 3.201 and FS version is 2004. I have no problem to change frequencies except the ADF one. I change the ADF frequency by reading offsets 0x034C and 0x0356 (these offsets actually reflect FS ADF frequency), modifying them as needed, and writing them back. This works OK except when the frequency I want to write ranges from 1700.0 to 1799.5. I can change and display these frequencies by clicking on the panel, but no way to do it through FSUIPC (but once they are modified manually, I can read the correct values through FSUIPC). As far as I know, the 'official' range of ADF frequency is 190.0/1799.5 kHz. I tried several combinations with no success: - write and process 0x034C, then write and process 0x0356. - write and process 0x0356, then write and process 0x034C. - write 0x034C, then write 0x0356, then process. - write 0x0356, then write 0x034C, then process. Any suggestion? Daniel Delande (d147@tiscali.fr)
