Hi folks,

I am looking for some ideas of how to solve this issue.
I recently tried a flight using the PMDG 777 in P3Dv5.3 HF2 and wanted to start my flight in Dublin in combination with trying out the latest version of FSHUD that performs simulated ATC.

When I tried to tune into the Dublin Clearance Delivery frequency 122.985, I got the "run around" from FSHUD because it was trying to send/set a frequency the 777 didn't understand as I believe the 777 does not have the radio capabilities in the sim of using 8.33kHz frequencies (just the 25kHz spacing is available in the P3D version). It is also not possible to use the radio panel to manually set a 8.33kHz frequency in the T7.

I contacted FSHUD Support and they confirmed that FSHUD works off of 8.33kHz frequencies now and clearly the issue is with PMDG not having updated the aircraft which is perfectly reasonable. I am told that FSHUD uses the Navigraph package as its source to display the required COM frequencies in its app.

Based on some PMDG forum posts I have read, this update won't come soon until PMDG have released their MSFS product portfolio and we know how long that is taking 😉

However I am looking for some workarounds in which I would still like to use FSHUD:

Q: For the purposes of the sim, would it be possible to modify the Navigraph Airac file so that the COM frequencies for Dublin Clearance Delivery were set to an "alternate" frequency that is compatible with the PMDG 777?
If so, which file would that be in the Navigraph airac  package (I have a Navigraph subscription) as I could not spot where the COM frequencies for each airport are stored?

If this is possible I could then also update the EIDW scenery I am using using Herve's AIE tool to set the corresponding frequency in the scenery itself.

 

Q: Alternatively, is there a way to write/send the PMDG T7 an internal command for a 8.33kHz frequency (even though it may not be properly displayed on the radio panel)  as I understood that  the underlying sim does (v5) support the new frequency spacing.
 

Any thoughts on how to get round this issue/dilemma?

Anyone else encounter a similar issue and how did you solve it?

Thanks in advance
Mark

Since you use FSHud, sadly not: the database you need to edit is hosted online in their servers. I hope to be wrong.

@787flyer, Mark, Radar Contact still uses 0.25Hz steps and it’s free. Plus you get me to watch your flying. 😉

@Ray Proudfoot Thx for the reminder about RC! I may well just try this out.

Can you remind me how does RC select the correct COM1 frequency? Does it work off of Navigraph or does it have its own database of airport  and navaid frequencies?

 

Thx
Mark

@787flyer, It needs MakeRunways by Pete Dowson. That reads all the relevant BGLs and creates csv files used by RC4. So frequencies are derived from your addon scenery as well as default ones.

RC4 has a Update Database option to import them. Runs on same PC as P3D or networked.

OK @Ray Proudfoot, let me review the installation process. Hopefully config is easy. Can you send me the new link for the RC4 download via PM please?

Done. Good luck!
