How does TARS work in the KA-50?

[Yassy]

The TARS control panel only allows to change the Guard frequency per sim, however the push to talk keys are a global setting in TARS for VHF AM, FM and UHF.
In the KA-50 we have VHF 1 and VHF 2 as radios. No UHF as far as I can figure out, but please correct me if I am wrong.

VHF 2 can be switched between AM and FM mode. VHF 1 cannot (again, correct me if I am wrong).
Does this mean we use FWD to talk on VHF 1 and BWD to talk on VHF 2 in FM mode?
Does this work out of the box?

You use your 'normal' TS PTT when flying the Hokum. You only have 1 PTT in the real pit, so the same is true in sim with TARS.

As with the A-10C, you can hear transmissions on both radios, HOWEVER, in order to transmit on a specific radio you must have the rotary switch set in the correct position. This means that, unlike in the Hog, you can't jump from one radio to the other as easily.

As for guard, again the Hokum differs from the Hog. While the Hokum does have a guard receiver, it's tuned to VHF guard (121.500) by default. You need to do a (very easy) edit to one of the .lua files to switch it to 243.000.

If you update the frequency to UHF 243.000 in the TARS control panel, will this alter the game files?
If not, then where should one change the setting in the BS2 files?

[Eddie]

No, the TARS setting doesn't affect the sim. I don't remeber the name of the lua file off the top of my head, but it's in the \Scripts\Cockpit\Ka-50\R-800 folder somewhere (or very similar file path, at work so can't check) .

MODULATION_AM = 0
MODULATION_FM = 1

modulation_speed = 50
modulation = MODULATION_FM
squelch = true
emergency_radio = false
adf_function = false
emergency_frequency = 243000000.0

something like this, Eddie?

[Eddie]

Exactly like that.

Thanks gentlemen!
