P3D v4 - a request

[Andy Parish]

Hi,

Can someone who's running P3Dv4 please try to tune the following frequency on the radio stack in a) one of the default aircraft, and b) their add-on aircraft of choice and let me know the outcome for both - together with which aircraft you were using for b).

121.935

Yes. That is a definitely a "3" inbetween the "9" and the "5". If you're able to tune this one and you've time, it would be interesting to see if it lets you tune 121.945.

Thanks!

Hi Andy
P3Dv4
Maule M7 260C only has 2 dec places But I can only tune 121.92 then jumps to 121.95
PMDG 737 only has 2 dec places But I can only tune 121.92 then jumps to 121.95

Hi Andy
P3Dv4.3


default Beech king Air 350 only has 2 dec places But I can only tune 121.92 then jumps to 121.95
PMDG 737 only has 2 dec places But I can only tune 121.92 then jumps to 121.95


Thus , same as John's

Thanks John / Henk,

What you've said confirms my suspicions that for the time being at least, P3D doesn't simulate radios capable of supporting 8.33KHz frequency spacing. 25Khz spacing would show the behaviour you're seeing; 8.33KHz spacing would show 121.920, 121.925, 121.930, 121.935, 121.140 and then 121.950!  There is future provision for support in the latest version of FSUIPC though - I guess all they're waiting for is the program to catch up.

The CAA started rolling out 8.33KHz spacing in the UK at the start of the year, with a completion date of January 2019. They're mandating that any aircraft that needs to work an 8.33 spaced frequency MUST be fitted with an appropriate radio (no s**t Sherlock!), so if you can do everything on 25KHz spaced stations, you're OK!. I don't know which other countries are currently using it (I'd venture to say none as yet given a big master list of all of the frequencies of all of the ATS facilities in the world I use), but it's going to become more of a "thing" as time goes on I suspect.

On the plus side though, I'm currently testing a version of the tuning plugin that allows X-Planers to tune the real frequency, and "the others" to tune a different frequency, but the plugin will place them both in the same room...
