    I have no problem navigating between NDBs if their frequency is a whole number, but in the UK, a lot of them have frequencies ending in point five, so half a kHz. The ADF panel in the Arrow only has space for 4 digits, - thousands, hundreds, tens and units, so how do pilots tune it to a point five frequency, for example Oxford's (367.5kHz)?

    The manual says only this:

    "The ADF frequency is displayed on three counters.
    The frequency is selected using the frequency select knobs which are rotated either clockwise or anti-clockwise.
    The right inner knob tunes the 1s. The right outer knob tunes the 10s. The left knob tunes the 100s and the
    1,000s."

      While older analog ADF radios like this one did not have the ability to tune in .5 khz increments, they also did not have the narrow bandwidth needed to completely block these adjacent frequencies... so, in the real world you are actually able to recieve these .5 khz frequencies, but at a much lower signal strength and range.

        As MSFS doesn't simulate the behaviour described by @RetiredMan93231, I've now added a hidden clickspot to the KR85 ADF frequency digits that toggles a 'fractional frequency select mode'. With that enabled, you can rotate the right inner knob to select fractional frequencies.

          Nice workaround. Thank you, Martyn :)

            @Martyn , Is it possible to configure it to automatically pick up the frequency dialed, and the next higher fractional frequency... like 341.0 and 341.5 for a setting of 341? This might be a better workaround if it can be done...

              @RetiredMan93231 Agreed, that would actually be more realistic if it's possible.

                @RetiredMan93231 I know JPLogistics was talking about doing exactly that with the Cessna 152 improvement mod, but I'm not sure if they've had success yet. I agree that's the ideal solution.

                  I've added some code which will automatically scan through the fractional frequencies based on your selection, which should hopefully address this.

                    @Martyn said in ADF frequency whole numbers only:

                    Excellent! Thanks...
