Re: Hammock Area
Why? A signal on the 18th floor will have a hard time reaching the first floor in my opinion. Also, if we only want to broadcast to the hammock area then why place the transmitter on the 18th floor? And the signal will need to be pretty powerful to get cover the entire height of the hotel. Just having a transmitter in the middle of the hammock area will not need a lot of power plus will be located right by the people listening to it. Thus we won't get as much interference and it'll be a lot easier to do.

Re: Hammock Area
I signal from 18 will not have a hard time reaching the 1st floor since the antenna would be located outside the building. but if its trapped in the middle of the 1st floor you are going to have people knocking it over left and right. And you wont have any interference on the 18th floor with the uplink to the radio station (or where ever)

Re: Hammock Area
The antennae can be hung from the ceiling of the hammock area. I don't really think that placing an antennae outside of the building is feasible when trying to get a signal only to the hammock area. From what I remember at Notacon FM transmitters arent thatstrong. If the signall couldn't penetrate 4 hotel floors then I don't see how a weak license-free signal positioned on the roof of Hotel Penn will penetrate the hotel's walls and the 18 floors leading to the hammock area.

Re: Hammock Area
Anything is possible, but how are you going to run the wire to the transmitter from the 1st floor? It was bad enough with the fiber cable from 18 to the NOC area, we used over 400 feet and we still came up short! Unless you want the transmitter on the 1st floor as well?

Re: Hammock Area
Well i know that every other HOPE they do a live OTH for 2 hours, so we would have access to at least some of the equipment needed to trasmit.

Re: Hammock Area
If I remember correctly from H2K2 they use some sort of broadband connection to stream the signal to the WBAI transmitter. Or at least that's how I understood it.
But do we really need a lot of equipment?We just need asmall fm transmitter. and something to play audio on.
I mean, something like this http://www.ccrane.com/radios/fm-transmi … itter.aspx (don't know how powerful it is) and something that produces audio. Maybe a small mp3 player.

Re: Hammock Area
They use a ISDN line to transmit the signal to the station. Not sure the exact equipment they use though. As for the FM that looks so cool! This is what I love about this 4m. You find out so many interesting things. We could even transmit each talk on its own channel and stream it over the internet, which is what we suggested last time. We should have more then enough bandwith to go around (assuming the cables hold up)

Re: Hammock Area
Villan, Slick0, and me had a VoIP box set up at HOPE6 to transmit the talks over the net and over a range of VoIP DIDs. It was also meant to be used as a way for people to call the world for cheap. We had a few SIP ATAs there along with some SCCP phones and it was ready to go but the 300ms delays between hops killed us. But, yeah, basically, it's all ready to go for the next HOPE. I think we even have the dialplan saved somewhere. Oh, and we also setup a bunch of VMBs on the box. At the next HOPE we can give out VMB logins and passes that people can use to get voicemail on the Asterisk box.

Re: Hammock Area
I don't know. I don't think I ever found that out. I remember there was some network problems on Friday but on Saturday the biggest problem that I saw was the insanely high latency and something about the DHCP server for the wired LAN not working properly.

Re: Hammock Area
If we can get the NOC up in enough time before hand, we should run the VOIP over the Microwave link. This is what we wanted to do last time but we wound up lossing so much time because of the move.

Re: Hammock Area
I forget who said this but it might not be agood diea if the microwave link sends out the packets in bursts. Then we'd get random drops in audio and random, uncontrolled jitter. That is if it sends it out in bursts.

Re: Hammock Area
It doesn't burst. Last year I mistakenly said that it uses compression but I have come to find out that is incorrect. the bandwidth we have is all ours as little or as much, no compression, the dish is just opened wide and all the stream comes in unrestricted. The microwave has less then 6ms latency and has VOIP running over it now with no issues at all. What we get is a steady constant stream (well as constant as anyone can be). Last time we hooked it into NAC, I think this time around I think we should just leave it on Rainbows link and let them handle the traffic.

There is a range-boosting hack.

Re: Hammock Area
As long as you people don't accidentally reverse the process and start broadcasting from the hammock area. Nobody needs to tune in live and direct to the various bodily noises of a herd of sleeping hackers.

Heh, that's the same link that I posted. I didn't know that there'sa range-boosting hack but I did find a review that said that the reviewer could hear the signal clearly from the other side of his house on anothe floor. Since the hammock area isn't that large we might not even need to boost the range to have all the hammock people in range.

Re: Hammock Area
Okay, speaking as someone who's looked into this, there's a really EASY and really COOL solution.
Pick up one of these to start:
http://www.pcs-electronics.com/2007-ste … p-968.html
Power available up to 2W... 2W on the hammock area (hell, the LPFM version would work, too) hooked into a PC that's loaded with music/talk/whatever would cover everything we needed...
AND it can sit in a corner back in the NOC, headless, and do its thing.
I've been planning for over a year to buy one for myself... if I do, and it works as well as I think it will, I'll gladly bring a machine that we could use.
