LNM only shows one airport radio freq

Featured Replies

When i use LNM to find radio freq data for various airports, it will only show the ATIS freq and one single tower com freq (always the lowest in the list).

Example: EBAW:

FS gives: ATIS: 124.205 - GROUND: 121.905 - TOWER: 119.700 - TOWER 135.205

LNM gives: ATIS: 124.200 - TOWER: 119.700

Now with the LNM tower info not complete i'm left in the dark when using the returned tower freq in FS that i pull from LNM. FS uses 135,205 in game as tower freq for comms at EBAW and although it also mentions 119,700 as freq, i never get any ATC on this freq, So the info returned by LNM is useless.

Any suggestions on getting the entire com freqs to show in LNM?

What simulator?
Which Navigraph AIRAC?
LNM version?
Scenery database settings (Navigraph for all features, etc.)?

LNM takes the COM from the Navigraph database while getting the airport from the simulator database. For EDDF I can see four tower frequencies for cycle 2010, for example.

Simulator: FS 2020

Navigraph AIRAC: ?

LNM version: latest beta

Scenery database setting:  Navigraph - AIRAC Cycle 1801: Use Navigraph for Navaids and Procedures

 

Update: Overlooked the "COM" tab in the information window.

Q: Why is the freq rounded to (example) 135,200 while in FS it's 135,205 (and there 135,200 does not give any coms)?

Good catch. This is a LNM bug. Frequencies should not be rounded to the next 0.025 MHz if using the new 8.33 kHz channel spacing. I implemented this already for X-Plane but it seems MSFS uses the same scheme. I will fix the problem.

The offset "bug" can either be + or - 0,005 Mhz so not always rounded to the next 0,025Mhz, it can be rounded to the previous one to.

I'm rounding. This also means I can go down to the next 0.025 for old radios. But this is obsolete.

For X-Plane and MSFS (next LNM release) I take the values without any modification from the database since they give the channels.

Information base on this article.
