When I fly near KSMX, I am handed off to LA Center at 121.90. However, 121.9 is not LA Center, it is KSMX ground. This happens every IFR flight that may fly within a distance to KSMX.

I am handed off from 119.05 to 121.90 and then back to 119.05 when I have flown far enough north or south.

I fly using BATC and have reported this issue to them directly, however I’m wondering if this issue is a Navigraph issue, since BATC is just pulling nav data from my AIRAC of choice.

Could someone look into this for me?

Thanks.

Hi,  
And without our data installed, it is working correctly, so no handoff to another frequency…

Cheers

Ok, so are you saying that there _is_ an issue with Navigraph?

Or are you asking me test again without Navigraph installed?

Your response is unclear.

No, I have asked if it is working as you expect it, when you don´t use our data (means with the stock data only).

Not sure, what is unclear here …

Cheers,

Apologies for the misunderstanding. Your initial reply contains no question mark, so I was trying to understand if you were making a statement or if you were asking a question of me.
