Hi folks.
Dave G4DPZ and I have generated some provisional keps for Wednesday's launch
from Vandenburg.
Usual conditions apply....good for estimates over a couple of days.
Assumes 18.32UTC launch and no change in planned altitude / inclination from
last week.

Hi Jim,
We use Kuhne (DB6NT) products all over the place here at VT.? For the
Amateur Satellite Service I would recommend this:
https://shop.kuhne-electronic.com/kuhne/en/shop/power-amplifiers/MKU+PA+70CM60
W+HY++UHF+MOSFETPower+Amplifier/?card=650
50mW in for 60W out or there about, pretty nice and straightforward
final stage.? Needs a pretty hefty heat sink, and some control circuitry
built around it.? If you are looking for something outside the Amateur
bands, they also have a whole other commercial line of products, many of
which overlap the ham bands (good for 'dual use', but may require your
own filtering).
Getting up to 100W or above I second the W6QPL recommendation. He also
has a lot of useful 'widgets' for rolling your own solutions (like a
fine sequencer that could be used in conjunction with an SDR to control
the PA).

I'm putting the following antennas on an 8-foot fiberglass crossboom:
M2 2MCP8A, 143-148 MHz C{
Gulf Alpha 70cm 8x8 CP
WiMo Helix 23
I'm not sure how to calculate the proper spacing on the crossboom. I
assume the 2m antenna should go on one end and the 70cm antenna on the
opposite end. Can I mount the 23cm helical antenna very near the rotator
without harm since it has the solid reflector behind the helix?

That's pretty much what I did, though with different antennas. Also put
the AO-40 dish on the other side of the rotor from the 23cm helix, so it
went 70cm, 2.4gig, rotor, 23cm, 2m. Put things as far away from each
other as you can, without running out of crossboom.
I was very concerned about having the 70cm beam (uplink) so close -
inches - to the 2.4 ghz dish (downlink), but it was fine. Good input
filtering in the 2.4 ghz Khune preamp, I guess. More recently, Mode L/v
on AO-92 seems ok too, with the 23cm antenna near the 2m, but I have a
lot less power on 23cm than I did with AO-40 on 70cm.

Yuri UT1FG/MM will be going into port at Santos Brazil tonight
or tomorrow morning to unload. It should take 3-4 days.
His next port will be in Argentina where he will load
cargo and then proceed to the Baltic Sea. Lots of new
grids are anticipated along the way. He has been active
on all of the ssb and fm birds and reports contacts with
V51 and ZS on AO-7.

Concerning tomorrow's ARISS contact with Ecole Primaire Jean Jaur?s et
Arnaud in Troyes, France, some of the original student questions have been
changed. Refer to our original press release posting on Nov. 24, 2018 for a
complete list of the original questions. Below are the new questions.
Q1: How are you enjoying your mission?
Q7: Were you sad about the Soyuz abort last month?
Q11: Will your future travels bring you to Troyes?
Q15: When taking photos of Earth, can you see Troyes?
Q19: Is there a phone on the ISS and do you ever have the chance to speak
with French Astronaut Michel Togini from space?
Q22: Do you sleep when it is night outside?

All,
Just a reminder that tomorrow, Nov. 27, is giving Tuesday. I hope some of
you get out there and give to your favorite cause. I also hope AMSAT and
ARISS are at the top of your lists.
The following is on the top page of the ARISS web site. Take a look at:
www.ariss.org <http://www.ariss.org> The donate button is there too. So
please consider a donation to ARISS.
It should also be noted that while folks are giving to their favorite causes
tomorrow, the ARISS hardware team will be presenting to NASA the thermal
modifications made to the power supply of the ARISS next-generation radio
system If we get through this hurdle, our next step is flight hardware
fabrication, flight testing and launch! Please wish the ARISS hardware team
the best!
Thanks for all your interest and support to ARISS! Ad Astra!

**************
Tuesday, Nov. 27 is <http://www.givingtuesday.org/> #Giving Tuesday, when
many people donate to a favorite cause. Gifts to ARISS on Tuesday or at any
time of the year are a wonderful way make a difference to our youth, to our
communities and to the amateur radio hobby. All ARISS donations via AMSAT
(including Fundrazr) are tax deductible to the extent allowed by law. If
donating directly to AMSAT, be sure to designate "ARISS" on your check, in
the PayPal notes or in your letter. Our readers can consider doing the same
thing John Carobine, WB8RFB, did -- here is his letter.
I'm not one who considers myself influenced much by advertisements but I
recently made a donation to AMSAT-NA to support the ARISS mission of
bringing technology awareness to a whole new generation of young people
because of one; namely, the Kenwood advertisement on the back page of the
July 2018 edition of QST Magazine. I "connected" with it and it made me
want to support this program in whatever capacity I can.
In part, the ad stated "The ARISS mission is to provide and operate Amateur
radio systems in space aboard the International Space Station, helping
inspire, educate and engage youth and communities worldwide in science,
technology, engineering and mathematics."
The last 11 years of my working life were spent as an adjunct instructor of
adult education in my local college's GED program. I taught some of those
subjects. As I told my students "knowledge is power and power enables one
to have many options." The mission statement struck a cord with me having
worked in various capacities in each of those areas over the span of my
entire working career. I spent twenty years in the U.S. Navy working in
various meteorological, oceanographic, electronic and computer maintenance
and management capacities. Those activities plus additional formal
education opened future employment doors for me in the civilian sector for
30 additional years.
Exposing school students via ARISS to the possibilities of careers in STEM
is nothing short of positive. As stated so many times before, we never know
what lesson, activity, or casual statement will open a person's mind and
inspire them to greatness.
As I celebrate 47 years in amateur radio, I encourage others to reflect upon
what amateur radio has meant and done for them. I hope that you too will be
inspired to "pay it forward" and help preserve and promote an avocation that
has meant so much to all of us.

I few years ago I acquired a ThumbNet USB Rtl-sdr dongle. They were made
available by a group called Thumbsat (thumbsat.com). I have never used it
but it appears different than the N3 they now have available. I can?t find
any of my documentation. I was wondering if anyone has any experience with
this item. I hope to try using it with SDR#. The only experience I have in
this area is with a funcube dongle, which I have misplaced.
If anyone has suggestions or can point me toward some documentation I would
appreciate it.
