AJS37 Viggen: Radio Tutorial | DCS WORLD

[@AdurianJ]

When the Fr-22 Fr-24 was developed a new smaller radio was developed for the Draken to basically the same technical standard called Fr-28. That radio was then bought by the RAF for use in their Nimrod and AWACS aircraft and they really liked it :D

You're talking about FM as though it's a band, like HF, VHF and UHF. This is wrong. FM and AM are encodings. FM means your voice is carried by small variations in frequency, rather than variations in signal strength (amplitude). The receiver has to be set to decode/interpret it by the same method as the sender used to encode it. This means there's nothing stopping you from having a conversation at 250 Mhz using FM, so long as the other party is also using FM on the same frequency. Traditionally some bands are designated to use certain encodings, but these are technically speaking just conventions. Usually you want guard frequencies to be global or similar, the idea being that many radios can listen to both a designated frequency and the guard frequency. I'm reading things as H being the guard frequency in the viggen, but heck if I know. I'd like to see how this interacts with srs for listening to global as you have a local channel for a viggen flight.

Thanks Marius, you have just refreshed my memory on something that I'd forgotten decades ago (regarding the AM/FM encodings).

[@grimreapers]

Oh bugger. I've just recorded all of the radio vids and was unaware of this :( :(

[@Earl11]

I am not certain about the terminology. Shouldn't it be the modulation instead of encoding?

[@mariushusejacobsen3221]

Probably. I think of modulation as a form of encoding, and encoding is a term more people are familiar with. I may be wrong there.

If you know Swedish here's some more info on the radio www.aef.se/Avionik/Notiser/Fr22-Fr24_Notis.htm At 4:08 the Norm+Larm setting means you use the regular radio but the backup radio listens on Guard/Emergency frequency

thx AJ

@@grimreapers Seems all the buttons on the Fr-22 works the knobs are for presets in combination with the number buttons. For instance all the airfields have presets, just like they have landing coordinates for the TILS. Just looked that up i'm really not that good with the radio

[@corychester5865]

Cap....Rescue from GR Discord here. There is so much more to the viggen radio. The channel selectors does work. U need to open the kneeboard to see what presets are. Also it works with SRS and you can have up to 3 different freqs at one time on the radio system. If I want to talk about it and see me in chat playing on your server, I'll be in public voice if I'm online, I can help ya refine your viggen radio knowledge. But the key is working with the kneeboard. You mostly wont need all 3 radios setup but its kinda cool. Cheers I'm off to watch your mig21 videos as I just got it.

Although regrettably I'm presently having serious issues with DCS that is preventing me from getting on any Multiplayer servers, both yourself and Marius have helped to clear-up comms (ahem), vis On-board radio and SRS with the Viggen. Now I just have to find out what is going wrong with my DCS as ED don't seem interested in helping me out; still, that's modern game developers for you (as a whole). :-/

[@grimreapers]

Thx Cory. Every time I think I've mastered something, it turns out there 100 more things to learn about it!

[@andersmeameigard3928]

FR-22 VHF in the Viggen was only between 100,000-159,95 MHz, UHF was between 225,000-399,950 MHz. FR-24 was110,00 -147,00 MHz.

[@grimreapers]

ah thx

[@lasselahti4056]

Umm. Does that manual radio tuning work all the time / only when [ - ] is selected? And where is special 3? there is only H, 1, 2 and empty button?

[@Madeyes6]

I’d like to know how I can change presets in game, not in missions editor. Also can I have both radios set to different frequencies for the likes of SRS so it’s similar to Comm1 & Comm 2 in the Harrier & F18

[@grimreapers]

can only change presets in editor :(

[@Madeyes6]

Oh really? That’s a bit crap. Thx for the info.

[@Madeyes6]

Can you set the 2 radios for SRS to have 2 different channels?

[@corychester5865]

@@Madeyes6 yes u can madeyes. I'll look for u next time and show u how

Isn’t that done via the kneepad?

[@ThunderDucky187]

Cap, is this tutorial still applicable after all the updates?
