Setting Radio Nav frequency

[Fredflyer]

Hi all,

is it possible to set a radio nav frequency using the event NAV1_STBY_SET using XML and how ? (FSX SP2)

Thank you

L:Nav2Freq,number) (>K:NAV1_STBY_SET)

You will, of course, have to set the initial value for L:Nav2Freq,number yourself, and also add/subtract 0.50 as needed.

thank's for the tip.
i tried that

 <Script>
  1 (&gt;G:Var1)
  111 (&gt;L:MYNAV1,number)
  (L:MYNAV1,number) (&gt;K:NAV1_STBY_SET)
</Script>

but it seems not working...i displayed the result of (A:NAV STANDBY FREQUENCY:1, Megahertz) and the value dosen't change...

Did you configure your aircraft.cfg to ALLOW for standby NAV radios?

[Radios]
// Radio Type = availiable, standby frequency, has glide slope
Audio.1 = 1
Com.1 = 1, 0
Com.2 = 1, 0
Nav.1 = 1, 1, 1
Nav.2 = 1, 1, 1
Adf.1 = 1,0
Transponder.1 = 1
Marker.1 = 1

Well N4gix, you were right for the aircraft.cfg, but it seems that the event only switch from nav active to nav stby...because when i change the frequency with the buttons, the stby frequency change.
the value i pass is not given to the frequency...or there's a problem with the value i give...i did something like 111, probably i have to give 11100 or 111.00, because the SDK says "NAV1_STBY_SET Sets NAV 1 standby frequency (BCD Hz)"

N4gix, you gave me the way...
i understood what was wrong...in fact the aircraft.cfg is to change if you use stdby freq for flights...for me it is used but in background, not for flying...so the value is set to 0 in this file (Nav.1=1,0,0)
the problem for the event key is to give the right value, with the right format...here it's BCD...
so you have to give something like 0x11130 for the freq 111.30
then everything works...which is for example

0x11130 (>K:NAV1_STBY_SET)

Thank's for your help and answers even if i found the problem myself...asking and speaking helps everytime for everything...it's brainstorming !

See you for other questions and problems.

No problem, Fred. Yes, if you wish to tune the active COM or NAV freqs directly, you do need to set the section in aircraft.cfg file to zero for the standby radios.

Then to tune the standby freqs you need to use the _SET key events as you've done.

I've only done this in a C gauge (which is honestly much more difficult), but understand the basic XML syntax. I did forget to mention the requirement to encode in BCD format... <oops!>

Here then is a <Macro> that will make life a bit simpler...

<Macro id="NAV1StbySet" Name="NAV1StbySet">
 <MacroValue>
	100 * 10000 % int (* 123.45 to 2345 *)
	d 10 % r 10 / int (* stack: 234 -&gt; 5 *)
	d 10 % r 10 / int (* stack: 23 -&gt; 4 -&gt; 5 *)
	d 10 % r 10 / int (* stack: 2 -&gt; 3 -&gt; 4 -&gt; 5 *)
	16 * + (* stack: 2*16+3 -&gt; 4 -&gt; 5 *)
	16 * + (* stack: (2*16+3)*16+4 -&gt; 5 *)
	16 * + (* stack: ((2*16+3)*16+4)*16+5 *)
     (&gt;K:NAV1_STBY_SET) 
  </MacroValue>
</Macro>


@NAV1StbySet(L:NAV1StandbyFreq,number)

Place the <Macro> script within your <Gauge> section. To use it, simply use @NAV1StbySet(L:NAV1StandbyFreq,number).

Set (L:NAV1StandbyFreq,number) in a <Mouse> routine and increment/decrement as you desire.

thank's for this code
probably i will use it in another gauge on day.
