Hi Ross, 

Very feasible, there are a number of CubeSat projects that are trying to do 
exactly that. 

It seems the problem these projects have is getting a launch - it's not easy. 

For example two projects, Project Calliope and Euroluna, will both be testing 
Ion Motors. They booked a launch on the same rocket some 3 years ago now, as 
yet the rocket hasn't launched. 
http://amsat-uk.org/2012/06/20/interview-with-author-of-diy-satellite-platform/
http://amsat-uk.org/2013/03/01/ion-propulsion-euroluna-update-on-cubesat-ht-power-supply/

They seem they are plenty of other projects also planning to use CubeSat 
propulsion but in all cases launch availability/cost seems to be the limiting 
factor. I'm sure many of these projects will eventually get up there and who 
knows maybe one or two might even work as intended first time, others may need 
two or three launches before everything is perfected. 

I think over the course of the next 5-10 years we should have viable CubeSat 
propulsion systems that can go from a 310 km orbit to HEO, may take a few years 
of flight to get there but I'm sure it can be done. Of course they'd need to 
address the radiation issues that Brent mentioned, although a CubeSat that 
simply went from 310 km to a slightly less hazardous 1400 km orbit would be 
good.

BTW the Lunar Pocket Spacecraft project, announced in June, is another one 
planning to use propulsion, see

[amsat-bb] Orbitron and WispDDE - Flipped Mode Issue

[Fabiano Moser]

Hello,

I am having trouble to understand how Orbitron and WispDDE works to get
right Flipped passes of ISS over my QTH.

Some times when ISS come from South América and cross over Europe my rotor
need to work flipped, because my stop is North.

Some times he do, sometimes not, then after cross 360º my rotor need to
make a complete turn while is possible to go till 450º.

Here is an example of one pass where rotor is NOT Flipped.
http://img827.imageshack.us/img827/2755/cj0l.jpg

Anyone had the same problem and/or can help me?
Thanks.

Best regards,
Fabiano Moser CT7ABD

[amsat-bb] Rolf in EN17

[Les Rayburn]

Worked Rolf last night on FO-29 operating portable from EN17. Nice 
signal from the mobile set-up! Thanks Rolf for a new grid for me. I'll 
be uploading the log to LoTW tonight, and putting a card in the mail 
soon too.
If you need EN17, you won't do better than trying for this first class 
operator.

[amsat-bb] Polar Tracking LEO Satellites ... ?

[Rob]

I'm looking to put together a quick an easy portable tracking system for
LEO birds  maybe something for field day use or an ISS school contact


Basically looking to do polar tracking with one rotor and a manual set
declination angle 

Thoughts are:

- rotor that can swing 180 degrees (-90,+90)
- set the rotor to the half way point (0 degrees)
- position the whole apparatus so that it's pointing at the azmith and
elevation of the highest point on the pass
- position the rotor to -90 for a west to east pass or +90 for a east to
west pass
- calculate the length of the pass and time the rotation so it sweeps 180
degrees in that period

I'v been googling this topic till my eyes cross  saw some data about
folks trying to do polar tracking of Ao-40 a while back ... but that was a
tad different considering Ao-40 is (was) in a high elliptical orbit ...

Does anyone have advice ... or a link to some data  calculations ...
like how to convert az/el to something like (but not) declination/ra 

Thanks,

--> Rob, KA2PBT

[amsat-bb] Winterization project

[Greg D]

Hi all,

As I reported on the 20m Amsat Net (14.282mhz Sundays 18:00z - 19:00z) 
this morning, I noticed that my 2m antenna was listing slightly 
down-hill.  Suspecting that the boom attachment screws had come loose, 
my project for the day was to go up on the roof and align and tighten them.


The screws were a little loose.

That's not why the antenna was drooping down.

I discovered the real reason:  Acorns.

Apparently the local squirrels have been preparing for winter, such as 
it is around here, and had stuffed about a dozen plump acorns into the 
open end of the antenna boom.  Besides their weight climbing out to the 
end, there was also the remaining weight of the acorns.


So, the antenna ends have been taped over, but that's not going to 
prevent the squirrels from climbing out onto the antenna.


Any suggestions on an effective squirrel deterrent?

[Rick Tejera]

Rob,

See my article in the April/May issue of the AMSAT Journal. While not
motorized, I'm sure it can be easily adapted to be motorized. 

The basis is a simple Equatorial telescope mount.

If you need a copy let me know.

[amsat-bb] So50

[wyattdirks]

Today and quite a bit lately it seems So50 is becoming out of control. A few 
thing to consider when working So50 and the other birds.

1. Don't transmit if can't hear. Really so50 should sound like your local 
repeater its its not then you need a better rx antenna or maybe a preamp. 

2. If you hear someone talking let them finish the qso before you call someone. 
Also if someone calls somebody don't call the same person before they even have 
the chance to answer the first guy. 

3. Don't call people blindly if your interupting a qso. And don't continue to 
call the same person over and over if they aren't responding. Let people that 
are actually hearing the satellite make contacts. 

4. Do work full duplex. If you can't hear when your transmitting you're likely 
cuasing interference. 

5. Do enjoy so50 as it is the only fm satellite right now.

[amsat-bb] Re: So50

[Rick Walter]

Well said Wyatt. SO-50 sounds more like the Wild West the last few months. 
Unfortunately, the people that need to read this probably do not subscribe to 
the list. 

I do not consider myself a "perfect operator" but I try to be. 

ARRL should address this matter in QST. I seem to remember someone suggested 
this to them and where ignored. 

Ham radio's motto was always listen before you transmit. It sounds like many 
people missed it. I hear your #2 every time I'm on that bird.  

Thank you Wyatt.

Wyatt,

All good points!  I just hope I was not one that was causing QRM on SO50.

I just recently have my IC910H working with both rotor control and
CAT for the radio for Doppler  control.  I have noticed that at
times the uplink freq can be off.  I am working on getting it tweaked in.

I have  the LVB controller and Yeasu G5500 Rotator and I am finally
getting it to work for me...Had com port problems

[amsat-bb] FW: So50

[Craig Gagner]

I have to agree with Wyatt, SO-50 is getting beat up due to the fact it’s the 
only FM bird left right now. Follow Wyatt's recommendations and it will be much 
more enjoyable, especially for the had held folks. I did that for a long time 
standing in all kinds of weather and conditions, so give them a break when you 
hear them.

Also is it really necessary to make a contact with the same operator on every 
pass every day.

Wyatt, Great chatting with you today on 29, will have to do it again soon !

Very interesting, Greg.I was concerned about my vhf/uhf beams I want 
to put
up  before winter.  I used the red plastic tops of Boost Protein drink 
bottles and

they fit nice over the ends.

I broke a few of them but was able to cover all of the booms well.

I had the squirrel problem at the Sterling homestead a number of yrs
ago.

There used to be a company that sold hot pepper stuff in a caulking tube 
that you could put where birds would roost.


The birds would land, get a "hot foot", and leave.

Might be worth googling a bit to see if it's still available.

Unless, of course, your squirrels enjoy spicy food!

Hi all,

As I reported on the 20m Amsat Net (14.282mhz Sundays 18:00z - 19:00z) this 
morning, I noticed that my 2m antenna was listing slightly down-hill.  
Suspecting that the boom attachment screws had come loose, my project for the 
day was to go up on the roof and align and tighten them.

The screws were a little loose.

That's not why the antenna was drooping down.

I discovered the real reason:  Acorns.

Apparently the local squirrels have been preparing for winter, such as it is 
around here, and had stuffed about a dozen plump acorns into the open end of 
the antenna boom.  Besides their weight climbing out to the end, there was also 
the remaining weight of the acorns.

So, the antenna ends have been taped over, but that's not going to prevent the 
squirrels from climbing out onto the antenna.

Any suggestions on an effective squirrel deterrent?

Greg  KO6TH

I was thinking Aguila Super Colibris, 20 grains of .22LR low noise, 
anti-squirrel CIWS.

[amsat-bb] Re: So50

[Michael]

Not really active right now  so I haven't heard what's going on with 
SO-50 but I can well imagine. I would guess the main problem is what it 
most often always is on the FM birds.  A lot of hams like to try and 
"sell" sat ops by telling folks that all they need  is a dual band 
handheld and an Arrow antenna.  The problem is that there are very few 
if any full duplex capable dual band handhelds  available right now and 
less and less full duplex mobile rigs.   If you don't have the 
capability to be able to hear your own signal, you have no business even 
being on a sat, much less an FM one. Full duplex capability is the only 
proper way to operate satellites, especially an FM one, and how we ever 
got away from that line of thinking is a mystery to me. Gosh knows, 
handheld radios are really cheap these days, we may not be able to buy 
full duplex ones but it's not that big a deal to buy two. Just my 2 cents.

Well said Wyatt. SO-50 sounds more like the Wild West the last few months. 
Unfortunately, the people that need to read this probably do not subscribe to 
the list.

I do not consider myself a "perfect operator" but I try to be.

ARRL should address this matter in QST. I seem to remember someone suggested 
this to them and where ignored.

Ham radio's motto was always listen before you transmit. It sounds like many 
people missed it. I hear your #2 every time I'm on that bird.

Thank you Wyatt.

Today and quite a bit lately it seems So50 is becoming out of control. A few 
thing to consider when working So50 and the other birds.

1. Don't transmit if can't hear. Really so50 should sound like your local 
repeater its its not then you need a better rx antenna or maybe a preamp.

2. If you hear someone talking let them finish the qso before you call someone. 
Also if someone calls somebody don't call the same person before they even have 
the chance to answer the first guy.

3. Don't call people blindly if your interupting a qso. And don't continue to 
call the same person over and over if they aren't responding. Let people that 
are actually hearing the satellite make contacts.

4. Do work full duplex. If you can't hear when your transmitting you're likely 
cuasing interference.

5. Do enjoy so50 as it is the only fm satellite right now.

[amsat-bb] Re: Squirrel Repellant

[Clint Bradford]

Go to your local nursery. They will have solutions (there's a pun there) - 
including 
urine of other animals (usually LARGER animals (grin)) or placing a ring of 
"barbed"
wire on the mast - making it un-climb-able.
