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.

I'll see if I can move the frequency off 147.455 if I can get a custom
oscillator...the cheap one from Digikey puts it right on 147.455...it's a
design I've been working on for a cheap 2m FM transmitter for balloons.

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.

Mark,

Is the frequency list stable enough to be added to the GPSL web page?

Probably is OK to be added. Can you reach the page w/o signing into

update it I can just do it there.

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.

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.(?)

Re: GPSL update

Ralph & all,

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
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?

Zack Clobes <zclobes@...>
 

 


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

paul.verhage@...
 

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.

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.

Mission Control

paul.verhage@...
 

Is anyone planning to attend the launches but not go on chase? If
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

paul.verhage@...
 

I'll be in Kansas on the 1st of July. At that time I'll make
reservations at the Gold Fork and Sirloin Stockade for 20 people.
Is there a consensus that that is a good working number?

Paul


Proceedings

paul.verhage@...
 

I've only had a couple of people ask for Proceedings. I'll collect any
manuscripts at the symposium. Afterwards, I'll make them
available in bound form. If you'd like a copy, let me know at the
symposium.

Paul


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.
