fitness88 Posted August 21, 2018 Posted August 21, 2018 As an example, Sochi airfield has VHF 127.000 and UHF 256.000 associated with it, is one used for ground control and the other when your far away? It seems UHF can only reach the tower when I'm very close to the airfield. Thank you.

That is, what the different ATC frequencies are there for. There are no "advanced" procedures or SOPs implemented in DCS for talking to ATC - all ATC frequencies do the same. This might (hopefully!) change when ED tackles the ATC rework in Two Weeks.

Beamscanner Posted August 21, 2018 Posted August 21, 2018 I think LOS is modeled. But not diffraction, refraction, or atmospheric attenuation. Meaning there is no extra range from the VHF signal. Technically both UHF and VHF can propigate beyond LOS IRL. Just more so for VHF.
SmilingBandit Posted August 21, 2018 Posted August 21, 2018 Generally military aircraft use the UHF channels, older military aircraft may not even have a VHF radio. Civilian aircraft don’t have UHF radios. Modern software defined radios have the ability to do either band but fighters still tend to use UHF. In the heavies I work on we tend to hang out on VHF since we fly with the airliners hear more of what they are saying about the weather. Our command and control is almost all UHF.
Flagrum Posted August 21, 2018 Posted August 21, 2018 So both VHF and UHF have the same range? Also, is a weaker signal from the ATC as I fly further away modelled in DCS? Afaik aircraft radios are modelled in some depth (transmit power, LOS, etc.), but I never really looked into the range question - although I would expect it to be modelled if there is a difference in RL. That said, it is probably a different story for ATC right now. I would think, ATC's radios have all the same range and the only difference modelled is the name of the band they use - but without any other properties. So probably your aircraft radio can reach the ATC, but not vice versa - or the other way around. :smilewink:
fitness88 Posted August 21, 2018 Author Posted August 21, 2018 Let me ask you all this, do you find the ATC voice gets weak and a bit static when out at a certain range...this seems like a recent re-modelling of the radio?
