Ross,

The L-band uplink is currently active until 0145 UTC on 8-Oct. When the
L-band uplink is active, the UHF uplink is not.

You can check if the L-band uplink is active by looking for the L band
uplink value to be "TRUE" or "FALSE" in FoxTelem or on the website at
http://www.amsat.org/tlm/health.php?id=4&port=

Mode changes are announced on AMSAT's Twitter (@?????? at

Hi Ross,

It's listening on L-band, per the schedule.  Are you transmitting on L-band
or the normal 70cm uplink?

Thanks to all, now I know, so in the meantime, I will continue to
concentrate on the other 2 birds until 92 comes back on..
So next is some gear for the 23cm uplink.

Everyone:
A genuine newby to satellites, I plan to get QRV with U/V bands as soon as
I can (likely few months yet) due to difficulty procuring the orbital ring
rotors required to clear the trees at my QTH.

My goal is to work as many DXCCs over time as possible (and probably WAS
too).   Given this goal, is L-band helpful (will there be even 1 or more
new DXCC QRV on L-band that is easier or not workable on U/V) vs.
conventional U/V bands or should I stick with U/V given my
interests/goals?

Thank you 73,

Dave KJ9I

Ross,
If the satellite is in 1.2GHz uplink, are you trying to transmit up on UHF?
Please note: AO-92 placed into L/v mode at 0145Z and will remain in this
mode for 24 hours.

Hi All,

FUNcube-1

    As you will know, AO73/FUNcube-1 has been in full sunlight for over
    one month and has been transmitting continuously high power
    telemetry for most of that time. This has now been changed to full
    time amateur mode so the transponder is once again available. With
    the more stable on board temperatures being experienced, this means
    that the transponder frequencies are also now more stable. We expect
    to leave it in this mode for some weeks so that the team can
    determine whether or not the currents flowing from the solar panels
    are having any noticeable effect on the spin period.

FUNcube-2

    The FUNcube-2 transponder on UKube-1 continues to be in full time
    transponder mode. There are occasional breaks in service for a few
    seconds when the OBC reboots and the other onboard transmitter sends
    its CW beacon.

FUNcube -3 on Nayif-1

    EO88/Nayif-1 continues to perform nominally with high power
    telemetry when in sunlight and amateur mode when in eclipse.

With their slightly different orbital characteristics it is useful that
AO73 is now the early bird, EO88 comes over in the mid morning and UKube
provides coverage in the afternoon.

We have been suffering from some network issues in relation to uploading
the telemetry from the Dashboards to the Data Warehouse over the past
couple of weeks. Apologies for this, but hopefully everything is now
stable again. ie fingers are still crossed. Thank you for all the
telemetry that you upload.

Like many other teams, we are presently waiting for the next Space-X
launch from Vandenberg which is expected to be carrying a number of new
amateur payloads, These will provide additional transponder and STEM
capabilities for the amateur satellite service. Exciting times ahead.

Hi Ron:
These antenna options are both fixed RHCP:

Directive Systems Helix (single in Radome)  14.5dBic (approx. 12.3dB)
https://directivesystems.com/1200-mhz/23-cm-1250-1300-mhz/dseh23-12/
Wimo Antennan & Electronik GmBH  23-4 Helix  P/N 18027  16dB
https://www.wimo.com/helix-antennas_e.html

I have read that L-band AO-92 required loss budget (from this reflector
input) is 100w Effective Radiated Power (ERP) departing your transmit
system.
I believe there was a post on this email reflector from University of Iowa
(or similar) hams who operated band L.

My experience level:  I have not operated band L (just read about current
happenings).

Hi!

I will be part of a day of satellite operating from a deck on the RMS
Queen Mary, docked at Long Beach in southern California, on Saturday 15
December 2018. Operations will be portable, almost like a Field Day, and
should include FM, SSB, and possibly packet. All operations from the
Queen Mary will be as W6RO, the call sign for the wireless room on the
ship operated by the Associated Radio Amateurs of Long Beach. Depending
on staffing in the W6RO wireless room, there may also be HF activity
during the satellite operation.

Amateur radio has a long history on the Queen Mary, including a special-
event station GB5QM that operated as the ship made its final voyage from
England to Long Beach in 1967, and in almost 4 decades with the W6RO
operations from Long Beach. More about the history of amateur radio on
the Queen Mary is available at:

https://queenmary.com/history/amateur-radio/
http://aralb.org/club-station-w6ro/

I had the pleasure of working AO-7 from W6RO in March 2016. An article
covering this quick operation appeared in the AMSAT Journal, and is
available from the "Articles" folder in my Dropbox space:

http://dropbox.wd9ewk.net/

as well as an AMSAT-BB posting after that activation:

http://amsat.org/pipermail/amsat-bb/2016-March/057636.html

QSLing for the W6RO satellite activation will be handled per the procedure
on W6RO's QRZ page:

http://www.qrz.com/db/W6RO

with one exception: no QSO numbers will be given during the satellite
operation. Satellite QSOs from W6RO will be done in the normal manner, with
an exchange of call signs and grid locators. W6RO is located in grid DM03.
W6RO does not use Logbook of the World, so all QSL requests will need to be
mailed directly to the W6RO address in QRZ.

Thanks to Endaf Buckley N6UTC, the Associated Radio Amateurs of Long Beach
and the ARALB's W6RO Wireless Room Manager (David Akins N6HHR), and the
Queen Mary management for their work in arranging this event. I look
forward to another opportunity to work satellites from the Queen Mary.

Ron,

There has been a wide variety of antennas used for AO-92's 1.2 GHz uplink.
Some are using a 16-element Comet CYA-1216E sold in various ham stores:

http://www.cometantenna.com/wp-content/uploads/2013/09/CYA-1216E-inst-sheet.pd
f

Others have gone with Yagis from China via eBay. The 10-element Yagi has
been popular:

https://www.ebay.com/itm/1-2GHz-12DBi-GSM-Yagi-Directional-Antenna-1200MHz-N-F
emale-Connector-22cm-cable-/161112874419

There is also a smaller 5-element Yagi available on eBay:

https://www.ebay.com/itm/1-2GHz-Stainless-Steel-5-Elements-CCTV-Wireless-trans
mitter-Yagi-Antenna-SMA-M/321386720435
?

Some are using other larger Yagis, and K5ND has used a 23cm helix:

https://www.k5nd.net/2018/04/satellite-qso-l-band-ao-92/

If you want to build a Yagi, there are WA5VJB designs for smaller (4 to
10 elements):

http://www.n5dux.com/ham/files/pdf/D-STAR%20Antennas.pdf

Or for something larger:

http://wa5vjb.com/references/LBand-Yagis-for-AMSAT.pdf

Most of the time on the L/V passes, I'm using a 5-element Comet CY-1205
Yagi sitting on top of my Alinco DJ-G7T. Between the 1W from the HT and
this Yagi, which was sold in the late 1980s and into the 1990s, I have
done OK with AO-92 L/V. I have also used the 10-element Yagi from eBay
with my DJ-G7T.

As for power, for those using HTs like the DJ-G7T or an older HT like
the Icom IC-T81A, the power level is 1W. With a mobile radio or the
larger satellite-ready transceivers, 10W. There may be some who have
more than 10W going out to the antennas on 1.2 GHz.

A good discussion about working AO-92's L/V mode has been taking place on
a thread in QRZ's satellite forum. Once you get through the first part of
the thread, you can see this discussion, along with pictures.

 Hey Jack!

9600 baud packet requires something in the area of 15k of audio bandwidth
to work properly.? While I've heard from some folks that they've been able
to operate 9600 with a Signalink, here is the spec. from Signalink's
website:

------
Audio Freq Response: Approx. 300Hz - 3.3Khz @ 600 ohms
------

... so, as you can see it's perfectly suited for thinks like 1200 baud
packet or anything else that uses the traditional voice range up to 3k
(audio), but it's just not the "right tool" for 9600.

The other factor is the radio - for anyone else reading this, please be
sure to use a radio with a 9600-capable DATA port.? For the same reason
that the Signalink's audio bandwidth hampers operation at 9600 baud, on the
radio end of the connection you need a DATA port that works above the 3k
audio range.

Your computer's sound card might be fine but if you'd like to have a
dedicated sound device for interface to your radio's DATA port, I've had
great luck with this item:
