Oh yes, there is certainly such a permit.
If your radio is certified, than this permit simply is a matter of filling
out a form, filing ist, pay the fee and then pay the annual fee.
However, there is no requirement to actually have a radio installed,
provided you are not going to fly in (German) controlled airspace.

Hallo,
Anybody versed in german regulations?
Is there an official requirement - "aircraft radio license", to have a
radio in a german registered glider?
Not a "operator permit" but some oficial permit to have a radio
installed....

Thanks.

Andy
