Exporting the F-14 TACAN to Helios, channels come out wrong.

[Maverick-90]

Hi,

i'm working on exporting the F-14's TACAN and Datalink frequencies to my external screens, however the values are always one channel off.
TACAN is 45, Helios shows 56 same goes for the Datalink, Freq is (3)12.0 but Helios shows 23.1
is there a way i can offset all these Values in Helios by -1?

Thanks in Advance
Maverick
