In AMVI we are always committed to the best realism achievable, but sometimes you have to compromise aircrafts' tech specification to achieve a better realism level during the mission. The radio net is one of this thing, expecially if you want to fly russian helos with NATO standards, needing the ka-50s to be US equivalent assets. Obviously as you may find in the corresponding manuals, the AH-64 has a very different radio equipment than the Ka-50.
Speaking of planes only, in the current DCS layout there aren't any AWACS or ATC dedicated solution.
We don't need any airplane talking with any helo. We only need that tactical commander & game master slots (& loATC slots maybe) to be able to communicate with either planes or helicopters, either using UHF, VHF-AM and VHF-FM frequency. That will allow any people to work as AWACS, FAC (JTAC), ATS and Ground troops roles.
I note, with v0.0.1.6, than a JTAC can not talk to a Ka50, Mi-8 on their R828. Better is an extension of JTAC radio from 30.000 to 150.000 or add a 3rd FM radio.
That is what we (and I bet many other) need
About R-800L1 use:
As stated in the manual, the R-800L1 is used either for datalink and communication with, apparently, no data corruption. I'm not that much into R-800L1 tech specification (if anyone could really know about) to know how they archieved this. I may say that the manual state also that the Ka-50 has 2 R-800L1... I may think that both work on the same freq, one is used for voice and the other for data.... but I always thought that it was simply a manual error. This is a thing that I may look into... and maybe I'll report you any interesting findings, if you like
