It appears that the west has decided to leave those air bands to foreign influences. Those propaganda stations also do not appear to care much wether a band is deemed an amateur band in your country or not.
I would sincerely hope so too. Moreover, if or when the BBC closes its longwave service it'll bring serious pressure on the few remaining countries to close their LW services.
With the abandonment of the LW Service the Band will be up for grabs and there will be pressure on WRC/ITU to reallocate the spectrum. My guess is that's likely happening already but these days I'm not close enough to the ground to know. So I'd strongly urge Amateurs everywhere to start campaigning before it's too late.
I'm an ex-amateur but I still strongly believe in the movement and its objectives, and I think that if or when—more likely when—the LW service officially closes (by WRC-set deadline) then the Amateurs should be ready to immediately step in.
No doubt there will be pressure from others (possibility stockbrokers wanting to take advantage of the ionosphere beating fibre in transmission speed around the globe for their ultrafast stock trading), so I'd expect there to be a real bun-fight for this valuable LF spectrum.
Personally, if or when reallocated I'd like this Band to go to scientific research and this is where amateurs could step in to help, here they'd share the Band with scientific researchers. One such example which I've raised on HN before is earthquake prediction. It's already known that in many instances that before earthquakes ocurr the crystalline rock structure is under such pressure that it can generate piezoelectric fields and these can affect the height of ionosphere and in turn the distance it reflects RF transmissions will change. This effect is most noticeable at very low frequencies and can be detected.
A network of stations would be needed around the world to monitor these frequencies constantly and the Amateur Service could provide this.
There are other options too. Even though I'm no longer involved in Amateur Radio I'm concernd with its flagging numbers (I suppose once a member of the Amateur fraternity always a member). As an alternative to the BBC's closure, I even see ways for the Amateur Service to make money, perhaps Amateurs could not only mod the BBC's transmitters but do so a at vastly reduced cost then actually run the stations at reduced cost (see my other post to this story). The BBC could justify this unorthodox approach on both maintenance and running costs and that the LW Service is now less important given the low number of listeners (maintaining the uptime percentage would be less important, etc.).
BTW, I expressed my concern about the Amateur Service's flagging numbers on HN only yesterday: https://news.ycombinator.com/item?id=41949118
Marconi T or L antennas with capacitance hats and loading coils are well within amateur practice on 630m[1] and 2200m, and common from 40m/7MHz on down.
Not very efficient still; an ERP of 1W, as demanded by the 2200m band, can still take a lot of power on a less-than-ideal antenna. Similar story for 630m. (160m and up is usually not so bad, just that even a good Marconi on longwave is still too big for most people.)
But the current LowFER[3] regs limit the transmitter to 1W final stage input power, and a COMBINED feedline and antenna length of 15m. At least allowing amateurs to operate more here would allow more than just extremely low SNR modes like WSPR to be used at any real distance.
