need help understanding what is UHF , V/UHF and TCN radio ....??

[simo1000rr]

Dear all ,

 

as the title says im trying to figure out the differences and usage of all these panels in the M2000 , You see this is my first clickable interference plane on DCS ,Before I only loved to fly the F-15 and SU 27 and ofcourse as all of you know they are simple aircraft in terms of pre flight setup and things like that , all you need to do is turn power on and start that’s it and your flying and when you need to contact the tower no need to bother with radio frequency and such things . Now in the M2000 I see 3 radio panels with each one has its own inputs , UHF , V/UHF and TCN radio . all I need to know what is what and the difference between the three . I mean when do I use UHF and when do I use V/UHF and when to use TCN radio. Also how do I know which one is being used at the moment , like is there an indication that tells me which on is operating at the moment . im a bit lost pleas help .

 

Thank you all in advance.

Depends on what you're using them for.

 

The VHF radios tend to hug the earth, and do well in hilly terrain, however, I believe they have shorter range overall. I think it also has an advantage in wet weather. I think it also has the overall longer range AGL.

 

UHF signals have a better range for line-of-sight (At altitude; I believe VHF has more interference up higher), but is more affected by obstacles, though the reflections they produce make them good urban signals (Presuming you're in one, not trying to communicate to one, I think).

 

In a fighter I might want to use UHF for outer comms (Package or Tower), and use the VHF for intra-flight comms (Depending on a number of factors that I need to read up on), but if I'm in the A-10C doing CAS with a JTAC, it might be easier to communicate using the VHF and use UHF for intra-flight comms (I'm presuming due to the way it hugs the earth; the assumption I'm gathering from the JTAC usually being assigned a VHF frequency).

 

I'm definitely wrong, and hope someone who actually knows what they're talking about explains it, so I can learn the actual use too; however, that's what I gather from it. :thumbup:

 

EDIT: Forgot TACAN.

 

TACAN is a frequency set that's tied to navigation beacons. If you're set to the right band and frequency, you can pick up the signal, and know where it's coming from. It's the primary navigation for the older jet aircraft that do not have HUDs and/or on-board INS/GPS, along with another type of homing that doesn't give you range. So, if there is a TACAN Beacon at a runway, you can use that to get home.

For my experience playing on this M-2000c, the UHF Radio is used to communicates with other flight members as is secured (encrypted). Use only presets.

The V/UHF radio is used for communicates with ATC (i've successfully communicated only with ATC's at the moment). It use Preset or manual inserted frequencies.

Tacan is a militarty navigation radio (you don't speak with person), that allow you "only" to navigate to an airfield (A/R mode) or for example to a flying tanker (A/A) mode simply entering the related code (Ex 87X).

I've created a really simple chart with Mirage 2000c radio presets.
