One of the RAX presentations during the CubeSat workshop in April stated
that they're now targeting a September launch.
I'm assuming the delay is due to diffusers being added to all Minotaur
IV third stage steering systems to reduce unintended thrust after motor
burnout. Minotaur IV is launched out of both Kodiak & Vandenberg; I
don't see any reference to Kwaj having any launch capability for the
Minotaur family.

Does anyone have hands-on experience using an SDR transceiver?
If so, I have a few general questions:
- what unit did you use?
- have you used the unit for sat work?
- would you consider your experiences with the unit enjoyable or miserable?
- did the SDE unit come with an SDK?
- if you were to go back and do it all over, would you have gone with a
different unit?
Thank You,

I saw in the AMSAT Filed Day rules we get extra points for working digital
modes like PSK31, RTTY, etc.
Is anybody planning to work any of these modes during this year's FD? Has
there been any activity in the past?
Just curious to see if it would be worth the effort to give it a try,
especially in a demo situation.
I will be operating the satellite station for the K9MOT Motorola Amateur
Radio Club again this year. We will be a 2A Battery (QRP 5 Watts) operation.
Hope to work you in a few weeks.

Adrian,
In past years, the satellite digital modes for Field Day were limited to two
types of contacts:
1. PBBS contacts with GO-32: 3 points for uploading a message to ALL
describing your Field Day setup, and 3 points for each message to ALL that
you download. GO-32 may or may not be operational. (AO-51 is capable of
PBBS mode, but will be operating in FM voice for Field Day.)
2. APRS unproto 3-way exchange via NO-44 (semi-operational), ISS, and maybe
HO-68.
Detailed description of the digital mode rules can be found here:

Hi Steve,
Thanks for your note. I guess I should clarify my earlier question.
Please see #1 in the AMSAT FD rules:
1. Analog Transponders
ARRL rules apply, except:
- Each phone, CW, and digital segment ON EACH SATELLITE
TRANSPONDER is considered to be a separate band.
- CW anddigital (RTTY, PSK-31, etc.) contacts count THREE points each.
This is what I was specifically trying to address not PBBS or APRS exchanges
via Digital transponders.

Has anyone used "Stuf" from Cross Devices to waterproof RF connectors (with

I have made a LH circular patch for 2.4 GHz and mounted it as a feed for a
1'prime focus dish. I have successfully used it on AO 51. The Patch is in
air with 1/4 " spacing, The active element is rectangular with 2 opposite
clipped corners. It has less than 1 dB of axial ratio. It is fed near one
corner at the 50 Ohm point.

Hi Greg,
What I meant by "at best" is that it will certainly be a challenge (at 2.5
GHz) to get one panel just a perfect 1/4 wavelength forward from the other.
It will be equally as challenging (at 2.5 GHz) to make 75 ohm phasing cables
some odd multiple of 1/4 wavelength.
I say that because I found it quite challenging to make phasing cables for
1.3 GHz and even 440 MHz and I had a network analyzer to help me. Just when
I thought I had it cut perfect I put the connector on and found myself 10 to
20 degrees off. That will affect the circularity of the polarization. I
finally gave up and mounted the elements of one yagi 1/4 wavelength forward
from the other and used equal length cables.
Physical spacing is easier to achieve within a few degrees at the lower
frequencies (VHF/UHF). Another alternative would have been to use a 90
degree broadband hybrid (that can handle 25 watts) but that was much more $
than I wanted to spend.
If you have a helix already, I would use that. But don't let me talk you
out of experimentation. It is possible and might be fun.

Subject: RE: [amsat-bb] CP antenna from 2 WiFi panels
Hi John,
"At best"? Interesting... I've seen many diagrams about mounting two
linear YAGIs at 90 degrees from each other on the same cross arm, with the
appropriate phasing harness. My plan is to mount the two panels the same;
one next to the other, rotated 45 degrees in opposite directions on the
cross arm, with one pushed out 1.23 inches by a block of wood. How bad will
this be? One will surely get some elliptical effects when the satellite is
off-axis, but keeping them aimed at the satellite is what the rotor and
computer are for...
I understand that I'm losing some NF by not using a proper splitter, but I
don't have one handy, and this is (was) supposed to be a low effort
adventure. Again, for AO-51 VS, I should have plenty of margin.
I've built several helixes, both 2.4 ghz for the feed to my BBQ grill, and
my current L-band uplink, and could do the same here. But, back to the low
effort part of things...
If this simply isn't going to work, then I'll just leave my current setup
alone. It consists of a 3 3/4 turn helix feeding a 30 inch BBQ grill, lined
with window screen. All combined, it's kind of heavy, and the wooden cross
arm is showing the effects of the weight and its age. It was built for
AO-40, and for the current satellites I don't really need this much gain,
hence the replacement idea.
Bad idea?

shape of the patch and position of the feed point is typically how you
obtain circular polarization with a patch antenna.

Just ordered one for $14.99+ shipping. I comes with 12-inch coax
with NF connector. Other cables and /or connectors for $36.99

Look for the youtube video shot from the roof of the VAB. You can hear the
countdown in the background, and it is perfect. SpaceX must have had some
lag in their audio feed.

Ollie,
I have used Stuf since the 90's when I was doing Satellite TV installations
ie. BUD dishes. It works very well. The only thing the paste is very
slippery like Teflon, so once a connector is filled with Stuf and tightened,
one must wipe off the excess with a towel or paper towel otherwise black
tape or Coaxseal will not stick to the connector. Stuf is used to fill the
air gaps in connector once mounted.
In all the years that I used it along with black tape and Coaxseal, I have
never had a connector go bad on me or corrode. Keep in mind satellite
signals coming down the RG6 can be in the Ghz range and also supply voltage
to the LNB.
I have never tried it on ham radio antennas as I am "locationally"
challenged: ie. apartment.
Hope this helps. If you have further questions feel free to write me offline.
73, Adrian AA5UK

Has anyone used "Stuf" from Cross Devices to waterproof RF connectors (with
or without with coax seal)? It seems like a good idea but I wonder how well
it works in real life.

Did any one have the KEPS or a way to derive them?

Speaking of pannel
I try to get info's on a square patch antenna made by California Amplifier
described as "sich planar antenna/converter" PCS/WCS filtered
radar immune. There is a part number NO: 2240/020 Google search does not
return anything just a clue as it seems to be in the MMDS or
satellite range?
It is a flat pannel with linear polarization as there is V and H arrow
marking in the back making the pannel installation mounted as a
diamond instead of having the side of the square mounted parallel to the
ground.
