[Feature Request] Realistic Radio Values

[JurgenvRooyen]

It would be nice to have the option for DCS to use more realistic values depending on the radio in use. For instance the Tx power for an AN/ARC-182 should be higher (and the Rx sensitivity lower) than the AN/ARC-164.

I think it would be easy enough to pre-calculate the partial Friis (to match the current path loss method), and have a stored list of radios present in flyable modules.

However, I think there is a problem with identifying which specific radio is transmitting. Matching radios based on modulation and frequency isn't suitable due to different radios in the same aircraft covering the same frequencies and modulations. I believe some new field would have to be inserted into UDPVoicePacket class for this to be workable.

This was actually something I meant to implement at the beginning of the project - but I struggled to find the relevant information for each radio - settling on the ANARC 164 - as the datasheet was available. https://tsc-60.cellmail.com/tsc-60/TSC-118/rtn_ncs_products_arc164_pdf.pdf

It would be a breaking change of the UDP packet - but something I'm definitely open too. I'd probably send through the partial friis with the packet, or the power of the transmitter. This means that if clients arent in sync it'll still work, as all the information the client needs is in the packet itself

I had a quick mess around at a prototype to test ways implement it over the last week, and to try to source some datasheet or info for Tx power/Rx sensitivity. I ended up with this.

I haven't had the opportunity to test it, but I think it gets across what I imagine it might look like. I ended up thinking its probably possible to allow server owners to specify their own values for radios via a config file, and letting the server communicate custom values (if present) when a client connects similar to how the SyncedServerSettings are resolved.

As for values from datasheets, I was able to find data for about ~1/2 the radios. All the sources are commented in the RadioTypes class, sources that are suspect are labelled as requiring better sources (though I've used the values). If anyone does use these values (or this ends up as a PR), it'd be worth sanity checking the Rx sensitivity values as I'm not 100% the conversions I made were accurate.
