yes.

May i ask how?

Module. Dunno what it's called. Frequencies or Base module or.... One of the 3 modules.

Thanks a lot, i'll try to make a script out of it, so i avoid making a TFAR dependency into the .sqm because of the modules... when it's done i'll post it here

class same_sw_frequencies_for_side
{
displayName = "$STR_TFAR_Mod_SameSWFrequencies";
description = "$STR_TFAR_Mod_SameSWFrequenciesTT";
typeName = "BOOL";
defaultValue = 1; // Stef 0 = no, 1 = yes - make channels syncronized.
};

class same_lr_frequencies_for_side
{
displayName = "$STR_TFAR_Mod_SameLrFrequencies";
description = "$STR_TFAR_Mod_SameLrFrequenciesTT";
typeName = "BOOL";
defaultValue = 1; // Setf 0 = no, 1 = yes - make LR channel syncronized
};

Adding this into a .hpp file does the job... just Longrange frequency looks different for each radio i spawn.. to be precise i get the radios from an arsenal with RHS on, the shortrange is AN/PRC 152, longrange is MR3000 RHS.

EDIT:
previous stuff wasn't working so i opened the .pbo and found theese:

TF_same_lr_frequencies_for_side = true;
TF_same_sw_frequencies_for_side = true;

However global exec is not working and i found a post here https://github.com/michail-nikolaev/task-force-arma-3-radio/issues/1235 that says i've to set them into CBA setting..

So here's the final thing:
add a file into the mission .pbo called as cba_settings.sqf and added those lines TF_no_auto_long_range_radio = true;
TF_give_personal_radio_to_regular_soldier = true;
TF_give_microdagr_to_soldier = false;
TF_same_sw_frequencies_for_side = true;
TF_same_lr_frequencies_for_side = true;
TF_same_dd_frequencies_for_side = true;
TF_default_radioVolume = 9;

So CBA gonna read it and sync the frequencies. About the Longrange radio, the MR3000 RHS. is not getting syncronized while the vanilla ones do.

Hope this helps :)
