Dave,
I've built helical beams, before. Latest was 6-turn feed for an
offset feed dish to receive AO-40 on 2401 MHz. But back in 1996 I
built a 14-turn 437 MHz helical beam to try to hear MGS at 10M km
from Earth. Did not finish the 437 converter in time but did try out
the helical beam on uplink and found it not near as good as my M2
436CP42UG (not surprisingly).
I used flat brass strip to match 140 natural impedance of a helix to
50-ohms. The length was 1/4 wavelength and spacing from the ground
plane reflector varied from direct connection to the flange-mount
N-connector to about 3 times further at the connection to the
starting turn of the helix. Easy to tune by varying that distance
for best match.
I think 2m is the lowest frequency I would make a helical beam. That
20-MHz monster that MIchael links to - well I think I would rather
make a x-yagi (which would permit using either RHCP or LHCP). Most
amateur Jupiter radio astronomers only use a crossed dipole antenna.

Nah Dave,
that's not big, just a scaled down version of e.g. this one (for
~22 MHz, reception of Jovian storms, built by OH8PX, SK):
http://www.rfshamaanit.fi/hf_helix_1.jpg
Your impedance is about right too, but there are several neat ways
of getting this matched to 50 ohms in a fairly broadband manner,
easily googled.

Thanks to Jeff, WB8RJY for providing the correct Doppler.SQF file for
NAYIF-1 to me via email last night. Was hoping to work Jeff tonight.
Worked Perry, WB8OTH instead. I am running a Kenwood TS-2000 X into a
pair of eggbeaters with a pre-amp on the 70 cm side. Perry and I
played with our output power and could work each other at 5 watts when
the bird was near 10 degrees for me and below that for Perry. As
reported already, a very strong signal with NO drift. I set the dial
once with SatPC32 and did not touch it the rest of the pass. Sorry you
were not on the bird Jeff. Hope to work you soon.
Congrats to all on the Nayif-1 team. A great new satellite. #42017 is
the correct keplerian elements for this bird. Thank you Nico.

SAT OPs,
I'm attending an event south of Houston this weekendand am close enough to
venture to EL28 for an activation.
Not knowing the exact schedule for the event activities,
I can't specify which passes I would be on. The best times
appear to be for FO29 and SO50 early & late Saturday.

It would be most relevant if you can use a tether to form an electric
motor with the earth's magnetic field to raise your orbit.
Otherwise, things are much more complicated with a chemical or
electrical rocket because you have to carry your reaction mass with you
and then put energy into it to blow it out the nozzle at high speed.
There's a fundamental tradeoff in rocketry between rocket power and
propellant mass flow rate. You can produce a given amount of thrust with
high power and a low propellant mass flow rate, or with low power and a
high propellant mass flow rate.
E.g., to produce a thrust of 1 N with a mass flow rate of 1 kg/s, you
have to eject it at 1 N / 1 kg/s = 1 meter/sec. Ignoring relativity, the
kinetic energy in 1 second of exhaust (1 kg) will therefore be
1/2 mv^2 = 1/2 * 1 kg * (1 m/s)^2 = 0.5 joules
and since you need 0.5 joules every second, the required power will be
0.5 watts (assuming 100% efficiency).
If you double the exhaust velocity to 2 m/s, you can drop the mass flow
rate to only 1/2 kg/s and still get 1 N of thrust (1/2 kg/s * 2 m/s = 1
N). But you'll now need a power of
0.5 * 0.5 kg/s * (2 m/s)^2 = 1 watt
i.e., twice as much power for that same 1 newton of thrust.
So, which do you have more of, propellant mass or energy? In a chemical
rocket the energy is stored in the unburned propellant, so the energy
per unit mass is set by the propellant chemistry. That's why every
propellant combination has a theoretical specific impulse, e.g. 455
seconds for hydrogen/oxygen in vacuum. Specific impulse is just
effective exhaust velocity divided by g = 9.8 m/s^2, so the theoretical
exhaust velocity for hydrogen/oxygen is 4,462 m/s.
But in an electric rocket the energy source is external to the
propellant mass, so the energy/mass ratio can vary; you decide how fast
to eject it. If mass is cheaper than energy, then you want a low exhaust
velocity. If energy is cheaper than mass, then you want a high exhaust
velocity.
Since the rocket is free to move, the kinetic energy it produces will be
split between the payload/rocket itself (which you want) and the exhaust
(which is effectively wasted). The only way to get 100% of the energy
into the payload/rocket and none into the exhaust is to set the exhaust
velocity equal to the current velocity of the rocket so that the exhaust
comes out stationary. Of course, velocity is relative so you measure it
relative to the reference frame in which the rocket is initially
stationary. So to minimize energy consumption you want to increase the
exhaust velocity as the rocket accelerates. That's the exact idea behind
the VASIMR (Variable Specific Impulse Magnetoplasma Rocket).
The recent "EM drive" hype notwithstanding, I know of only one way to
produce thrust in vacuum without some kind of propellant: the photon
rocket. Even a flashlight will work, but let's do the numbers. The
momentum of a photon is equal to its energy divided by the speed of
light, so to get 1 newton of thrust from a 100% efficient photon rocket
requires a power input of 1 N * c = 300 megawatts!
That kind of power in space requires either a very large solar array or
a very big nuclear reactor (which still needs a very large radiator to
reject waste heat).
But there's a simpler way to power a photon rocket with the sun. Instead
of turning solar photons into electricity and back into photons, why not
use solar photons directly? Voila -- that's what a solar sail does. The
thrust produced by a solar sail per unit area is equal to the incident
solar power per unit area divided by the speed of light. At 1 AU that's
about 1361 W/m^2, so the thrust will be 1361 W/m^2 / c = 4.54 micro
newton/m^2. That's actually units of pressure, so solar radiation
pressure at 1 AU is 4.54 micropascal on a sail normal to the sun that
simply absorbs solar photons. If you reflect them back, you'll get twice
as much, 9.08 micropascal. Doesn't seem like much, but you'll get it
continuously, no local power source or propellant mass needed.
The one big problem with solar sails is that you can't use them in low
orbits because they'll generate far more drag than thrust.

Hi All,
JSpOC has released a new set of TLEs, which now contains additional objects.
Doppler and TCA measurements on several ground stations indicate the
best fitting object is 2017-008-BX, catalog number 42017
Over the coming days, we will be checking the performance of this
object, and we will be in touch with the other teams on this launch
that have satellites that are close to this object.
Happy tracking and thanks for all observations!

Hi Nico,
This arrived after my E-mail to the BB. You are right, we have
concluded the same.
I am still checking with the other teams if they have anything near
this object that fits, but chances are high that this object is
correct.
Thanks

Brush up on your French first!
School presentation
We are two small schools in pretty twin villages in the South of
France, Boissi?res and Saint-Dionisy. Enjoying very beautiful
surroundings, we are located just 15 km from N?mes and 40 km from
Montpellier in the Occitanie region, on the threshold of the Camargue
wetlands and the Cevennes mountain range.
Our villages are nestled at the foot of a hillside covered with
evergreen oak trees, juniper bushes, thyme, "capitelles" (dry-stone
cabins) and with a well-preserved "oppidum" (iron-age settlement) at
its summit.
>From the top, one can marvel at the splendid view over the plain of
Vaunage (stretching between Caveirac and Calvisson), the Pic Saint
Loup and the Mediterranean Sea on the horizon, and to the recognisable
architecture of the Grande Motte (seaside town). On a clear day, one
can even discern the peaks of Mont Loz?re, Mont Aigoual and Mont
Ventoux.
Our two little schools, served by a single school-bus-run, work
closely together within an inter-town educational grouping
("Regroupement P?dagogique Intercommunal") and maintain a privileged
relationship with all of the children. The Boissi?res school welcomes
61 pupils from kindergarten ("maternelle") to first grade ("Cours
Pr?paratoire").in three classes and the Saint-Dionisy school receives
daily 73 children from second grade ("Cours El?mentaire 1re Ann?e")
up to fifth grade ("Cours Moyen 2e Ann?e") - also in three classes.
The pupils are delighted to work together on a common theme between
the two schools. They are charmed by this wonderful project of being
able to communicate with Thomas Pesquet from space. They have been
carrying out lots of learning work and are making discoveries about
astronomy, the International Space Station and communication. We can
be sure that many are already dreaming of becoming the next Thomas
Pesquet!
Participants will ask as many of the following questions as time allows:
1. Selma (4): Est-ce qu'il fait nuit dans l'espace?
2. Elia (8): Qu?est-ce qui a ?t? le plus difficile dans ta pr?paration?

8. Alexis (8): Un des plus beaux cadeaux de notre enfance serait que
tu viennes nous voir : penses-tu pouvoir r?aliser notre r?ve?
9. Kylian (6): Qu'as-tu fait pendant le trajet jusqu'? la station spatiale?
10. Gabin (7): Est-ce difficile de vivre en apesanteur?
11. Gabriel (6): Est-ce qu'il pleut parfois?
12. El?a (10): Quelles ?motions ressens-tu lorsque tu travailles ?
l?ext?rieur de l?ISS?
13. Tatiana (6): Avais-tu un sapin de No?l dans l'ISS?
14. Maxime (10): Pourquoi fais-tu des exp?riences sur les v?g?taux dans l?ISS?
15. Louis (6): Y a-t-il des radiateurs dans l'ISS?
16. Ma?lle (9): Est-ce qu?il y a de la vie dans l?espace?
17. Leah (6): Est-ce que tu peux manger glac? ou chaud?
18. Zo? (7): Es-tu press? de revenir sur Terre?

This has been already taken to LoTW admins at ARRL but they insist in
blaming the "sat operator" as she/he registered the QSO with wrong/missing
information, which is true, but the system, LoTW the case, should avoid
confirming a match between two stations when one of them does not specify
PROPAGATION MODE = SAT. What LoTW actually does when one station specifies
it and the other not is to confirm a match QSO but the credit goes to the
terrestrial VUCC on VHF, UHF, etc. which, in my opinion, put high risk to
terrestrial VUCC credibility through LoTW confirmations.

Paul, may be I am the "lucky" one, but I have plenty of examples in LoTW
here.One of the most interesting is a QSO between PY and CT made via AO-40
satellite, where I have set satellite name and propagation mode correctly,
but the other station not, LoTW just credited terrestrial qso between PY and
CT on 1.2GHz.

Ed,
LoTW will not confirm a QSO when the propagation mode and satellite
name don't match.

blaming the "sat operator" as she/he registered the QSO with wrong/missing
information, which is true, but the system, LoTW the case, should avoid
confirming a match between two stations when one of them does not specify
PROPAGATION MODE = SAT. What LoTW actually does when one station specifies
it and the other not is to confirm a match QSO but the credit goes to the
terrestrial VUCC on VHF, UHF, etc. which, in my opinion, put high risk to
terrestrial VUCC credibility through LoTW confirmations.
