Hi Seth,

Thanks for your reply. You can find my signed-off-by tag below together with 
the unchanged patch.

I can affirm I did check this carefully with the official documents of the 
German administration for radio equipment (Bundesnetzagentur für Elektrizität, 
Gas, Telekommunikation, Post und Eisenbahnen).

I noticed that the links to the other entries for Germany are broken, as the 
website design was changed and thus all old link became non functional. I can 
provide a patch fixing this if it is something that's considered useful.


The comments to my initial mail indicated that the statement in the ERC 
recommendation I linked are alone not enough to add this frequency ranges for 
other countries. Unfortunately I don't have the possibility to do these checks 
for countries other than Germany.

If there is anything I can do to help adding the SRD entries for more 
countries please let me know.

Thanks,
Maxi
