Cool! Ideally I think we get both options working so most people can
be included (radio or phone) Once one is set-up the other can be done
easily as well.

Ah I see. Are radios allowed in the park? I guess I've been sort of
confused on the details of the amplification restriction. Does anyone
have that information?

i was initially a fan of the conference call route and did some work on it with ian, but i think radio is "lower tech" and more reliable and scalable (phones calls can eat minutes and speaker phone are ineffective in the din of zuccotti).  teleconference is more suited for people in disparate locations (e.g. among occupies).

Hey guys have you already thought about free conference calls? We have
been looking into all these options as well for the film screenings.
The conference calls seem don't need a device with an
fm receiver, people just dial a number and put in a pin and they are
connected the person who started the conference (and is speaking into
their phone). You can make it so that everyone else is silent (so
their noise doesn't interfere with the person who started the call.
That phone can be passed around to whoever wants to speak.

The drawback number of callers. Some sites have 100, some
less. The one we are looking at is called and has a max of
50. But if 50 people called into the line, they could put their phones
on speakerphone and I think that can help with distributing
information. The ones that have a larger number of callers allowed
(upwards of 250) cost money (although not much I think). If we did the
larger number of callers one, people from anywhere theoretically can
listen (you can even listen with google phones)

Anyhow, something to consider since most everyone has a phone (rather
than a computer or something that receives an FM signal)

I'm going to be testing this with a bunch of phones in the park
tomorrow around 4pm. Please find me if you'd like to help.

Thanks for your reply and comments on the proposal!

We have actually done this a couple of times, with some people from
media, using the PART-15 transmitters, USB audio devices, cables and
adapters that we have purchased ourselves ahead of time in order to do
this demonstration.

None of these have been widely announced because the transmission range,
money and space concerns have kept us from being able to reliably
provide something that would work as a demonstration for a larger

The proposal as written is intended for the first phase to be
accomplished in much the same way as you describe, using minimal cost
equipment to just do the FM broadcasting, not doing the streaming,
archiving, etc.

have you looked at these transmitters:

Yes, as far as we can tell from the minimal descriptions there, these
are *not* FCC PART-15 compliant, especially with over 3 miles of
transmission capability. This is O.5 W, which is over the limit for
PART-15. This would require a LPFM license, which is not trivial to get.

my suggestion would be to get one transmitter, one wired mic, one
shotgun mic (to pick up audience comments), and ask people to bring

We have two wired microphones (SM58s) donated, but they require phantom
power (ie. mixer board, which can be obtained for ~$120, we heard there
might have been one that was put in a green bin at SIS about 3 weeks
ago, we'd like to find that and use it if possible). We also have a
shotgun mic that takes a battery, but it is suboptimal for the purpose
as the cable lengths are poor, and the pickup very bad, it would not
work for a GA (we've tried). We have already two transmitters, cables,
adapters, etc.  which is over $200 already out of pocket. We can't go
any further without support from an official working group. We need
space, recognition and some resources to take this to
completion. Several of us are hauling a ton of equipment on our bikes on
a regular basis down to the square that I would really like to put
somewhere other than my already bad back.  We've been making callouts to
the local community asking for equipment donations and support, but have
thus far only received one offer that did not come through. The amount
requested is for the full project, but we could easily do phase one at a
lower amount, which I think would be sufficient to provide
demonstrations, but to do that, we are going to need some money to do
it. If I could front the money, I would.
