Hoping for 10:30-ish Pacific today 

No live feed available.

One YouTube channel is watching FlightAware ...

Good evening,



Is there a URL for a live feed of the launch?

New FM repeater soon - UVSQsat

David Spoelstra
 

The launch of UVSQsat is scheduled for January 21, 2021 by a SpaceX Falcon 9 rocket at Cape Canaveral, Florida. UVSQ-SAT is a nanosatellite designed by LATMOS (Atmospheres Spatial Observation Laboratory) and developed at the Observatory of Versailles Saint Quentin-en-Yvelines.  Its scientific and technological goals are observing essential climate variables, namely shortwave and longwave radiative fluxes at the top of the atmosphere and UV solar spectral irradiance.

In addition to experimental and educational missions, it will provide the Amateur Radio community with a new FM transponder:

Mike-
You can go to this page to see the current status of all the satellites: https://www.amsat.org/status/  AO-91 has been off for the last six days.

Drew,

Please excuse my question from a very green newbie. It comes from this post really.

Here in New Zealand I have been using AO-91 in recent months for the first time ever.

I use the ISS Detector software for pass information and it has been accurate.

I'm assuming that since the beacon announcement is no longer announcing that
the transmitter is off, the AO-91 service  in ZL is unavailable?

Thanks

Re: AO-91/92 Update

Clint Bradford
 

Its schedule is not "continent-dependent." It's "eclipse-dependent."

From AMSAT recently -

Recent telemetry shows that AO-91 hasn't recovered much if any yet, based on a short (about 10 day) rest. We can expect to soon see the AO-91 transmitter turned back OFF for an extended (indeterminate) rest...

Remember, please do not use either 91 or 92 in eclipse. Doing so will reduce the remaining life of the satellite.

ISS Radio Schedule / EVA

Clint Bradford
 

The amateur radio equipment aboard the ISS gets turned OFF during EVAs, and when missions are heading towards it and leaving it.

The ISS FAN CLUB reminds us:

On Jan. 19, Tuesday, astronauts Hopkins and Glover of International Space Station Expedition 64 U.S. will perform spacewalk #69, during which there will be the installation of the Ka-band antenna for Columbus COLKa and activation of Bartolomeo.

There will be NASA TV live coverage starting at 10:30 UTC; spacewalk is scheduled to begin at 12:05 UTC.

To support EVA on Jan 19 all HAM radio systems on the ISS will be powered off Jan 18 and return to service Jan 20.  Check for updates Current Status of ISS Stations.

Clint,
Awhile ago you eluded to postings on improving the dual band elk antenna. Is there anything in the mix other than the carbon fiber boom?
Thanks

Re: Tape measure style Yagi using PVC and Ladder line.

Siegfried Jackstien
 

i would not use a haipin match but a halfwave transformer

impedance of a folded dipole with parasitic elements is in the 200 ohms
area .. so a halfwave transformer is the right choice

the text in the homepage where you found the design has a fault ... a
folded dipole does not have 450 ohm ... also not when using the 450 ohms
window line (that in real is more 390 ohms or so) ...

hairpin match does not provide balancing and is lossy compared to the
halfwave line

Thanks Clint. Isn’t there any video of take off prep ?

AO-91/92 Update

Clint Bradford
 

From AMSAT - 

Today I turned AO-92's transmitter off after resetting the min-max readings. We've been watching the battery minimum voltage decline steadily over the last few days, and needed to give it a rest for a bit.

 

Immediately afterwards, there was an AO-91 pass. I turned on the transmitter, and a few moments later reset the min-max readings. The command team will monitor telemetry and determine if we can leave it on for a while.

 

Please remember to not transmit to either satellite while it is in eclipse. If you do not use software that indicates eclipse state, just avoid the evening passes. We are in the endgame for both satellites, and your cooperation will give us more operational time over the coming months.

 

Thanks and 73,
