Sorry I'm obviously having a brainstorm - I saw you mentioning 2174.5kHz, saw mobile on the graph and didn't read much further as I'd looked at this ages ago
The band affected is obviously 2045-2160kHz which as your link (page 22) shows :
a) is exclusively for military use;
b) doesn't appear to have any specific exemptions for low-power devices (it might have - I didn't look
too closely);
c) has a nice little entry called "Land Mobile"
Footnotes 2 & 11 apply as does 19. You'll note that Ofcom is quite happy to license
maritime mobile stations in this band which by a process of deduction should lead you all to realise that the UK military uses this band exclusively for land-based communications. With a little bit of digging you might even work out exactly what its used for but I'm afraid I can't tell you as (many years ago) I signed the Official Secrets Act
Now either Be are right and everyone else is wrong or there's something odd about the Speedtouch which requires them to block this band.
Its my opinion that Be are right not to be using the band and everyone else is wrong. If it does cause a problem then we'll find out as WBC rolls out.
