The idea is to divide the frequency allocation into blocks to make it easier to get an overview of the system and to realise the allocation for frequencies for specific projects. As already explained above, the default frequency is 300 and this should never be used. That makes the default the "off" position, which will reduce confusion to new pilots and make it easier to track errors. Frequencies below 300 (i.e. 200-299) will be for mission specific frequency use. This means that any mission builder can use any frequency in this band, without worrying that he or she will be over-writing "official" frequencies and thus leading to confusion (or errors). Frequencies from 301-313 will be used for the actual Knickebein frequencies, as discussed with ATAG_Torric270. Although the frequencies are actually NDB band, the set use of these frequencies will be in alignment with the historical station numbers and thus lend to the authenticity of our missions.
For 314-340, I've made this the first large NDB (non-directional beacon) block. There are numerous gaps to allow for future new map regions or airfield use. Additionally, I've avoided placing nearby airfields on adjacent frequencies and adjacent frequencies on any given map should be pretty rare with this scheme. Again, we are trying to have something authentic, in the absence of a detailed (100 Hz-resolution) system and in the absence of historical frequency lists.
The airfields covered are from all the existing ATAG missions (Cherbourg, Sealion, Fall Rot, Hellfire Corner and Kanalkampf) and include all locations from where the Ju 88, He 111 and Br.20 bombers fly. These aircraft are the only types that currently have this level of LW navigation systems.
The X-Gerät frequencies are also mapped into the NDB range, even though these are typically much higher. Although, like the Knickebein system, this is anachronistic in this usage, it should nevertheless serve as a suitable compromise, for their implementation, given the limitations of the existing smiluator engine. I've done the same for the Y-Gerät frequencies. Like the Knickebein, these are grouped and the last number of the station matches the last number of the frequency for ease of learning.
Although it is tempting to use blocks fo frequencies for specific missions (e.g. 310-319 for Fall Rot), this is flawed in that the missions will slowly evolve and new ones will replace the old. Sooner or later you will need to click through to 580-589 to get to the "current mission". Additionally, there should be common frequencies for common locations between maps. In the proposal below, the K06 (Mont Violette) would be a common Knickebein site used in several missions (e.g Seeloewe, Hellfire Corner). Likewise for common airfields (e.g. Tramecourt). It does not make sense to put these onto separate channels for separate missions. It also provides set frequencies for new mission builders, who can rely on (in the future) well-established blocks.
As indicated in one of my earlier posts, I would recommend against implementing frequencies for Bernhard- or Erika-Systeme just yet.
See my previous posts for references.

So, the next step... I have latitude/longitude coordinates for the K/X/Y series of beams, but these need to be converted into the FMB system and then checked to ensure they do not clash with existing scenery. Airfield NDBs are easier, but still this will need to be checked and implemented.
Then, templates will be created, so they can be dropped in to the existing missions and used in new ones.
If new map areas become available, then they will need to be assessed and new frequencies allocated to cover the common airfields used by bombers with radio direction navigation systems.
In the meantime, I'm inviting comment and suggestions.
