Hallo all,

in Lillehammer the german HF manager, DL1VDL, has told me that already in June of this year he had addressed the german administration and opposed against these new LF applications. So we can hope that our concern is taken into account and at least no transmitter for these applications will be allocated within the CEPT LF band.

Having read in more detail the German original of the proposal to allocate
 various LF frequencies to the pager service I note the following.

The questionaire appears directed at potential users of these frequencies for
pager services - ie there may be several networks operating independantly. It implies however that one individual network will use a single transmitter
 designed to cover the whole of Germany.  On that basis it would also be
 quite strong in most of the rest of western Europe.

The modulation is data in a 500Hz bandwidth, time multiplexed, and presumably
 is fairly similar to DCF39.

The notes point out that the 136.8 frequency is already allocated on a
 primary basis in countries outside DL, and any allocation must not cause
 interference to these.  Perhaps there are even more transmitters liable to
 appear unannounced on it!

Closing date for comments on the proposals is October 1st.  Perhaps some
 input from the DARC and RSGB would be appropriate before that date - but it
 is not long!

There is no indication of when the formal allocations would be made or when
 transmissions would commence.

It would be unfortunate if the 136.8 transmitter came on, but in reality
there is probably little we can do about it in a shared band.
