PMDG 737 Offsets

[Sandy1]

Hi Pete,

I am currently building a 737 home cockpit with the PMDG 737 NGX. Inputs are looking good (i'm using leo bodnar cards) and I'm working on outputs using open cockpits sioc. I've been looking through the offsets, but no matter where I look, I cannot find the offset for the frequency in the radio panels. Do you know where I can find these offsets, or how I can access this information?

Many thanks,

Will

I assume you are looking at the PMDG 737NGX offset document installed in FSUIPC documents subfolder?  I don't use PMDG aircraft, but are you sure they don't use the standard FS/P3D facilities for radios? I would think they'd have to because other things (like ATC, ILS, VOR), operated by the Sim, use them too.

For FS/P3D offsets you need the Offsets Status document, in the same folder.

Thanks for the response. In the offsets status document, I have found the offset for NAV 1 Frequency, and have tested it using the logging feature of fsuipc. However, I do  not get the result mentioned (for a frequency 113.45, it will output 0x1345). However, in my NAV 1 radio, the frequency is 113.70. for type S16, I get read 4976, as opposed to 1370. Do you know how I can fix this, or what the necessary type is?

I hope this makes sense!

You need to convert the decimal value to hexadecimal, so

        4976 = 0x1370

which would correspond to a frequency of 113.70 (BCD format).

Hope that helps,

John

Thanks so much! That is definitely the solution. I am using MobifFight for the simulator (just a temporary fix!). Do you know if this conversion is possible in MobiFlight?

Many thanks.

No, sorry - not heard of MobiFlight before. Just googled it though and it looks interesting...

Using a bodnar board and rotary encoder i just use the FSUIPC button list,   turn right for Nav 1 whole numbers inc.that cycles through 108-117, do the same for  left turn  fractions inc. then use the rotary push button to swap. And do the same for Nav 2.

This works on all my aircraft including PMDG.

Happy Xmas

Thanks Brian. I use leo bodnar for my inputs too. That setup is incredibly clever, and must be quite compact - might use it myself! Dual rotary push button encoders are ridiculously expensive, aren't they? Around £25 a piece?

Merry Christmas to you too!

It does look quite good - I was going to use OC cards, but I thought that it was rather a lot of money to spend, and I didn't even know if it would work. Apparently, you just plug an Arduino mega in (fortunately, I have about 2 lying around). The only problem is that they don't have many pins, so you don't get a very good "value for pins" as opposed to on the open cockpits mastercard.

Hi Sandy  I use 2 single rotary encoders 1 for Nav 1 & 1 for Nav 2.  Direct from Leo bodnar about £4.50 and the knobs are another £2.50.

You also have a program to download to set the rotarys up.

Cheers Brian
