Radio help needed

Hi,

does someone can do a tutorial about radio management, because i can't communicate with my wingman or ATC ?

thanks guy's.

I think the radio isn't working quite correctly yet.

The radio works mostly by using presets, but you can manually set the radio frequency from the front panel after you press "-" button on the main radio control panel.

The radio works mostly by using presets, but you can manually set the radio frequency from the front panel after you press "-" button on the main radio control panel.

I haven't yet seen any good, clear description of how to select channel presets, much less change the frequency on the panel.

Here you can see me choosing the special channel and setting the frequency:

First, turn off the easy comms, it's not working with the Viggen.

Second, don't touch the FR24 mode selector (located behind the radar stick), its broken currently, it will make the radios inoperative!

The main radio (FR22, V/UHF) has three "parts":

1. Special preset channels (marked red)

2. Base selector (marked blue)

3. Group selector (marked yellow)

1. Special preset channels

Buttons H, 1, 2, and "no name" (should be Special 3 :D) are the presets. The frequencies can be set in the mission editor, and can be viewed in the kneeboard.

By default, the H is set to guard frequency (121.5MHz), Preset 1 is your flight frequency (i.e. wingman).

The other presets seen in the kneeboard (E, F and G) are used by the backup UHF radio (FR24), which does not work at the moment.

Button "-" is used for manually dialed frequency.

2. Base selector

Used to communicate with the ATC. The right knob is used to select the base, with its number displayed on the window next to the knob (does not work). The buttons associated with the knob (marked blue) are used to select a particular ATC frequency. All bases numbers and frequencies can be found in the kneeboard.

For example, you want to contact the Anapa ATC. You can see from the kneeboard that its number is 1, therefore turn the knob to that number. You can also see in the kneeboard all the frequencies for Anapa ATC. Since the main radio is VHF/UHF, you can choose either 121MHz or 250MHz. As seen in the kneebard, the channels are A and C, respectively. So press button A/G or C/F.

By default, your starting airfield number is already selected at the mission start.

3. Group selector

Used to communicate with other flights (e.g. AWACS). Again, all the channels are in the kneeboard (see the second image, Groups).

For example, if we want to contact the AWACS, we can see its channel is 1-1. To contact it, turn the left knob to 1, and press the number 1. The first number indicates the group number (i.e. turn the knob to that number), the second number a channel within that group (press the corresponding button).

Unfortunately at the moment the right knob can only be turned by the keys, and the window display doesn't work.

Many thanks grunf, now it's more clear.

That's awesome grunf. Great explanation. :thumbup:

Great job explaining that Grunf. (Sorry, can't rep you again so here is a virtual +1 :thumbup: )

Glad you find it helpful. :smartass:

No problem, the virtual one is just as good. :D

Great explanation; rep inbound!

Great explanation; rep inbound!

Thanks. :)

Wow yeah, that made a lot of things much easier. Rep inbound indeed.

Thanks grunf....splendid contribution.

Thanks, this explains why my wingman was deaf, I was on easy comms!:thumbup:

Is the defective tuning wheel on the fix list?

Also we can only assign groups or units to radio attack menu, a runway attack or complete mission radio menu would be nice.;)

Cheers.

Here are some detailed facts about the radio(s).

FR-22 / FR-24

The increased utilization of the VHF-frequencies forced a transition to the UHF band (225 – 400 MHz) for the military aviation radio.

Constructed in 1964 it was the first flight radio to have both VHF and UHF frequencies (for legacy support) and could use both FM and AM and it was designed for the AJ 37 aircraft. It was supposed to be in the JA variants as well, but since the 35F Draken also needed a VHF/UHF station (but couldn’t house the large FR-22 system) the FR-28/FR-29 was developed and designed to fit both JA37 and 35.

The functionality of the system is:

· Voice communication airplane – airplane

· Voice communication airplane – ground

· Monitor guard channel

· Present audio signals from other equipment in the aircraft

· Intercom for two seater variants

· Intercom with ground personnel and GCI through wire

The FR-22 control panel has 2 preset rotary switches and 20 push buttons. Only one button can be pressed (radio button), releasing any previously depressed button.

The left preset switch is for voice/GCI and has 42 presets (indicated at the left). Each selection has 10 sub presets with preprogrammed channels, selected by the 0 – 9 buttons below.

The right preset switch is the base selector and has 84 presets (indicated to the right). Each selection has 5 preprogrammed sub presets, selected by the buttons directly above.

The top row has 4 individually programmed buttons and one manual frequency mode selection buttons.

The control unit is a fully mechanical construction with punched mylar tapes setting the individual frequencies for each sub preset/channel. A light barrier construction transfer the settings “digital” to the frequency selector (non mechanical –controlled by 5 VCO’s broadband transmitters).

VHF, 103,000 – 159,975 MHz (25 kHz channel separation)

UHF, 225,000 – 399,95 MHz (50 kHz channel separation)

AM and FM modulation on both bands.

VHF AM – 25W

VHF FM – 50W

UHF AM – 10W

UHF FM - 20W

Powered by main AC grid (3*200V 400 Hz).

FR-24

VHF, 110,00 – 147,00 MHz (50 kHz channel separation)

5 preset channels

VHF AM – 3W

There are two connections externally for communication with ground crew and GCI through wire, that are released automatically if the aircraft moves away. This made it possible to have a radio silent update of the pilot in a high readiness situation.

Added information:

The FR-22 and FR-24 have separate antennas, but when on the ground (nose wheel depressed) they are switched (since the FR-22 normally uses the belly mounted antennas) for better reception.

First, turn off the easy comms, it's not working with the Viggen.

Thanks a lot for the really detailed explanation, it really clears up how to use the Viggen radio ... hope the developer fix the remaining issues soon :)

@BravoYankee4 Thanks for the info!

+1 Great explanation

thx grunf

Thank you grunf for your detailed and very helpful explanation of the radios! Great contribution!

I am still in my early days on the Viggen and I do SP only. I have now (more or less...) mastered the basics in flying, navigating, radar usage and I just began learning how to employ the Rb-04E and Rb-15F effectively.

For my training the target usually consists of 2 or 3 tankers protected by a frigate and a destroyer (with 'Average' skills per ME btw). I now learned that in most of my solitary attack runs one or both missiles are shot down by the warships. Hence, I tried to engage them together with a wingman so we have 4 missiles running in. But I did not manage to communicate with him...until now! Thanks again mate.

Glad it was helpful. :D

Thanks grunf, that was a much easier explanation than all the others I've seen. Too bad so many components of it are currently not working – hopefully this is a priority for Heatblur. Right now I don't think there is any way to use SimpleRadio with the Viggen, for instance, on any of the popular mp servers.

Oh hey, thanks... the issue of actually trying to use the radio frequency knobs is still pretty significant, though, at least for me. They are unreliable to say the least.
