...and the reason unlicenced operators need to meet together to
discuss problems such as these in an attempt to find a mutually
beneficial agreement. Perhaps even a case for a centralised body to
maintain a register of frequencies - but that will come up on the
agenda (to be posted this afternoon).
To date, I have the following broadcasters confirmed as having
representation at the meeting of Auckland LPFM-ers next week:
Static
Twisted
Up FM
TLC Radio
Radio Chomsky
The Flea
KFM
Radio Southern Cross
Base FM
Spider FM
Bay Classics
Hope City
So far, no word from Julia, Fleet, or CBFM - but I've sent them all
invitation emails. Nothing from Wairau either (not sure how to get in
touch with them directly yet) - and I'm not altogether sure who is
responsible for the Tourist FM signal.
Come to think of it, I should probably get in touch with the NZ
Foundation for the Blind - don't they operate a transmitter in the
Newmarket/Parnell area?
Apna have declined with thanks (understandably), but Shyam has asked
to have a meeting with me privately. Might be another thing
altogether, but are there any pressing issues you'd like me to raise
with respect to operation of the low power FM band when I go for a
chat with him? Email me off the list for that one please...
There are also a couple of independent technical types, one or two
potential new broadcasters and one of my students, who has been
charged with the duty of relaying the content of the meeting to the
other members of his class.
I have deliberately left MED representation out of it for now - partly
because they're busy people (who isn't?), but mostly because it would
make sense for the LPFM broadcasters to decide what their position on
including them in such meetings might be...
