Hi Adrian, you are doing an excellent job at marketing your product ;-) As I do not have the time to proof you wrong, you deserve the chance to proof me wrong! I'll shut up now and stop objecting against merging your code. I won't be able to merge it myself before we enter the feature freeze

Hi replying to multiple posts here, I'll try to collect and answer to some arguments. First: I totally agree that our current nav/comm radio implementation is far from being realistic w.r.t. propagation of the radio signal close to or on the ground. This should be improved. I spent an hour

Hi Torsten, Regardless of the fact that you support or not the inclusion of this new radio code, I have to clear up some statements which are wrong. See below. I spent an hour or two reviewing your code and I still think your implementation should not be merged into the code base. Let me

In some cases, the used algorithm is plain wrong as we know by definition (ICAO rules) the propagation of the radio signal. Um... I would like to understand this statement. The algorithm has a physics model in. I am no expert in radio propagation, but after doing a bit of reading, by usual FG
