Re: Frequency coordination page
Zack Clobes <zclobes@...>
We're also interested in building a cheap, 2m
backup signal. I've attached the data sheets on a Motorola MC2833 (which
aren't being manufactured anymore, but you can still get them). Radio
Shack has a crystal that will put it in the 2m band (I forget where off the top
of my head) that they sell for about $1.
That's as far as I've gotten on the project - maybe
this summer.

The one I was planning on flying uses the MC2833 (flown it many times and it
works just fine, but unfortunately it's been discontinued). I'm working on another design using a VCXO from Digikey. - Bill WB8ELK

APRS equipped record breaking amateur rocket
Ralph Wallio, W0RPK <wallio@...>
NEWINGTON, CT, Jun 13, 2002--If all goes as planned, a group of Amateur
Radio operators and amateur rocket enthusiasts will make aerospace history this month by putting the first amateur rocket into space. If the attempt succeeds, the suborbital vehicle will carry its Amateur Radio payloads to an altitude of more than 60 nautical miles. http://www.arrl.org/news/stories/2002/06/13/4/?nc=1 "Spaceshot 2001" / �Spaceshot 2002� Update Page Record-setting September 29, 2000 initial test flight http://www.remarkable.com/rocket/ TNX es 73 de Ralph Wallio, W0RPK wallio@crosspaths.net http://members.crosspaths.net/wallio Defect prevention is better than cure

GPSL update
Ralph Wallio, W0RPK <wallio@...>
PAYLOAD DETAILS
Publicity requests are going out this weekend. Please review payload details near the top of http://users.crosspaths.net/~wallio/GPSL2002.html and forward additions/corrections/deletions to me ASAP. PRESENTATIONS Total time for presentations, 9am-noon and 1-5pm, will be 7-hours. We will have 8 presentations and need a few minutes of break time in between. Plan on having 45-minutes per presentation including discussion and questions. The first slot will be opening remarks and short ~5-minute program discussions, e.g., ANSR, EOSS, et al. A/V SUPPORT Paul collected A/V support requirements but did not confirm availability of equipment before leaving for an extended trip to the southwest. As I prepare my discussion it occurs to me that support for Power Point, a PC and projector, has not been confirmed. Just in case, I will be ready with a Power Point file and overhead transparencies. Perhaps someone as access to a laptop and projector that can be brought to GPSL so we can depend on having Power Point capabilities.(?)

I really wanted to come to GPSL, visit and write an article for Amateur Television Quarterly, but it just is not going to happen. A couple of questions: Is there someone that would be willing to cover the event with a write-up and photos? Will any of the forums be videotaped, and if so can copies be purchased? All the best to those that are going. I know you will all have fun.

GPSL reporter and video guru wanted
Ralph Wallio, W0RPK <wallio@...>
This is the second request we have had for a GPSL video tape. Seminar
toggle quoted messageShow quoted text
discussions would need to be taped morning and afternoon, a total of roughly 6-hours. Additional footage from the mass launch could be added to almost fill an SLP T-160. Required equipment would include a camcorder or video camera, a large tripod, a VCR (so the seminar master could be SLP), and either a wireless or wired microphone up forward near the speaker. Two or more volunteers could share the pan-tilt-zoom chore. I suspect there will be paid requests for more than just two copies. If anybody knows anybody who knows anybody that would like to take responsibility for this service please ask for their support. Anyone who would like to report on GPSL for Gene Harlan, WB9MMM, and his ATV Quarterly please contact him directly.

What are the chase frequencies for GPSL?

Helium
paul.verhage@...
If we order six tanks of helium for GPSL, I can get them at $45
each. I'll need 1.5 tanks, Mark asked for 1, and I've had a request for another tank. Please let me know if you need helium. I need to order two more tanks to get the lower price. Who can help me move tanks to the launch site? Paul

AV Equipment

I'll call my mom tonight and find out about the A/V equipment at
the library. She asked me to contact another person at the library, but I never got an answer back. I know there will be a TV/VCR and overhead. I want to confirm the LCD projector and PC. Paul

More GPSL frequency coordination items
Mark Conner <n9xtn@...>
A few questions for some of the groups planning to fly next
month.
I define "time-slotting" as the ability to keep your
transmissions between X and Y seconds after the minute, using the time reported
in the NMEA output from your GPS.
EOSS: Can your 144.34 payload time-slot
its beacons? What callsigns will you be using?
TVNSP: I believe you're using the
KPC-3+ second serial port to control transmissions for your 144.34 payload - is
this correct? If so, you can therefore time-slot. Are you planning
to fly a backup beacon - if so on what frequency? What callsigns will be
used?
WB8ELK: Can you time-slot your 144.34
beacons? If not, does it beacon every X seconds, or is it
semi-random? What call do you plan to use?
KD0FW: Is it OK to change your simplex
repeater to 147.585, or do you have another frequency you'd prefer?
Traveler: You sent me e-mail earlier
that your programming will not time-slot. Is it every X seconds, or
semi-random? I think as long as it's not too close to 60 seconds for a
repeat interval we shouldn't have a problem.
ANSR: since you're transmitting on 70cm
you can set up your telemetry as you wish.
I would like to use a 70cm frequency for chase comms - if we
use 2m we'll desense our data reception (though ANSR has the opposite
problem). We'll probably select a convenient "rally point" near the
predicted landings for everyone to head towards after they recover their
payloads so everyone knows where to go if they lose comm with the rest.
Depending on where we end up going, cell phone coverage ranges fair to
none. I have no problems using the NSTAR simplex repeater (if it flies) as
a chase frequency - this will let distant stations listen in on the
fun.
Once I get answers back on the above, I'll work out a strawman
proposal for the division of clock times and intervals to be
used.

so, I'd like to appoint you as Mission Control for the flights. We'd have to get you set up a day or two before the symposium. Paul

Meal Reservations

Got Helium?
paul.verhage@...
Here's the list of people I have wanting helium. If you're name
doesn't appear and you want helium, please let me know ASAP. I'll check email on Friday and update my list. If you get this message after Friday, please leave a message on my cell phone (208) 631-7162. Me Mark Conner Bill Brown Zack Clobes Mike Bogard Helium is $45 a tank, payable during the symposium. I plan to drop the tanks off at the Johnson Near Space Center on the 2nd of July. I'll pick up an extra tank. I'm assuming everyone wants just one tank. The tanks hold something like 240 cu ft of helium, so I've had to use part of a second tank to launch a 12 pound capsule. With the extra tank, we'll have 6 tanks, the minimum needed fo the $45 price. I'd like to see if I can talk someone into getting a second tank as a backup. I'll have all tanks gauged before leaving Linweld, just to make darn sure we don't get an empty tank. I still need to line up help moving helium tanks, Linweld will not deliver tanks at this price. Paul
