Is there any plan to assign fliers using tracking transmitters such as the BeeLine GPS and BeeLine radio trackers radio frequencies to prevent frequency overlaps?
Thanks,
Joe

To my knowledge there are no provisions set in place at this time.
The Recovery Team will be equipped with a GPS handheld and Modified USGS Topo maps to assist in locating and recovering if necessary. There will also be a Modified USGS topo map at the rangehead to allow fliers to plot points and find routes. If you would like you can also download the Potter NY Quadrangle from the USGS site in PDF form. Then you can get a free plug-in for Adobe Acrobat Reader which you can also use to plot points, track your location, etc. A nifty little tool.
If you would like to view the preliminary USGS topo map it is available for download from the PYRO site here (~4.5 MB). Please note it is still a work in progress and will not be finalized until June.

I would like to hear from more people flying about this topic. Please post if you are planning on using some form of radio communication to track/find your rocket, if you are broadcasting radio or video from it, or if it is a radio controlled descent. My simplest solution would be to have a sign-up sheet posted at the range on a bulletin board where you can write your name, callsign (if required) and frequency for everyone else to see. That should help avoid conflicting transmissions. Would this suffice for everyone?
(If you know your frequency now, then you could post it and other people could take steps to avoid it beforehand.)

Thanks! That sounds like the simplest plan to avoid confusion.

That does sound like a easy solution. That was how it was handled at Midwest Power last year.

I'll be using a GPSFlight system that uses a 900MHz radio modem. It uses a frequency-hopping spread-spectrum system, so I can't give you an *exact* frequency. (Not even a range...)

Mike arent these GPS units digital? if so they really cant overlap can they? i have seen radio beepers that just transmit a tone but they need a ham dont they?
sorry to be full of questions radio stuff is completly foriegn to me.

It depends on the unit and the technology. All I've been doing is googling the equipment as it is mentioned. It may be an issue where you need to find one rocket first before you can find the second since the closer one will overpower the other. Others you can program the frequency beforehand. Still others broadcast "voice" on an FM channel. As far as the technology goes, I'm not an expert on it. I'll have a sign-up sheet posted. Name, freq, HAM#, parking spot #, unit type. Then everyone can see who is using what and make side arrangements if necessary. Ex: two people are using the same units but will cause interference, they can make arrangements to launch at different times and/or wait until one is found before launching the next.
The fliers will be responsible for their own equipment, usage and making sure they don't conflict.

According to Neil's post in the "Range, Launch Site and Registration information" section:
http://www.ldrs28.org/Forums/messages.aspx?TopicID=70
"There will be a white board positioned near the RSO area for folks to post their frequencies."
Right now, my Big Red Bee is on 433.960. I'm going to bring my laptop and the programmer so I can change the frequency. I had a lot of trouble at the last Red Glare since someone was on my frequency (or really close). This makes tracking pretty tough.
In preparation for LDRS I posted a message on recommended channel spacing in the the Big Red Bee forums and got this response:
"I'd recommend 25 Khz spacing: 433.900 433.925, 433.950, etc. You could probably get away with less."
It sure hope we can get the word out on the white board. My sense is that there are a lot of Big Red Bee units out there. This should be interesting.
