Sunspot number this morning was 31 but band conditions were extremely poor, worse than with no sunspots.
Hope this is not the sign of things to come in this cycle 25. 

Recently, YouTube has clumsily inserted commercials into almost every video on its site. Video presenters are often interrupted mid-sentence. The intention is clearly to make the free version an uncomfortable experience and drive users to the paid version.

But, there is at least one way to watch YouTube without the intrusive commercials and without being forced to pay a fee. I access YouTube through the website youtube.com using the Brave Browser. Brave blocks ads and commercial interruptions. I haven't had any problems with this method yet although I am sure if it becomes widespread Google will find a way to block it.

A serious gear collector!

From ARRL:

As reported on Spaceweather.com, Canadian radio amateur Scott Tilley, VE7TIL, has snagged another signal from deep space. His latest conquest has been to copy the signal from China’s Tianwen-1 (pronounced “tee-EN-ven”) probe, which went into orbit around Mars on February 10. Tilley told Spaceweather.com that the probe’s X-band signal was “loud and audible.”

“It was a treasure hunt,” Tilley told Spaceweather.com. He explained that while the spacecraft did post its frequency with the International Telecommunication Union (ITU), it was too vague for precise tuning (X band is between 8 GHz and 12 GHz).

Launched last July, Tianwen-1 represents China’s first Mars mission. It consists of an orbiter and a rover, which will land on the Martian surface in May or June 2021. It is able to photograph the planet’s surface while in orbit.

Finding signals from deep space is a sub-hobby for Tilley, who seeks what he calls “zombie satellites” among other signal sources. In 2020, he tracked and identified signals from the experimental UHF military communication satellite LES-5. Tilley said he found the satellite in what he called a geostationary “graveyard” orbit after noting a modulated carrier on 236.7487 MHz. Launched in 1967, LES-5 was supposed to shut down in 1972, but it continues to operate as long as its solar panels are facing the sun, Tilley explained.

In 2018, while hunting for an undisclosed US government spacecraft lost in a launch mishap, he spotted the signature of IMAGE (Imager for Magnetopause-to-Aurora Global Exploration), a NASA spacecraft believed to have died in December 2005. The discovery delighted space scientists.

Tilley has also picked up signals from NASA's Mars Reconnaissance Orbiter, and the United Arab Emirates Hope probe, both orbiting Mars some 124 million miles away. He uses a homemade 60-centimeter dish and relies on software-defined radios (SDRs) to accomplish the task.

Radio amateurs have been listening for signals from space since the 1957 launch of Sputnik 1, which transmitted at around 20 MHz.

We had a request for help with an Icom 7100 from our website.  Does anyone want to take the lead on this and also interest the person in our club?  Here is the message we received:

ARRL to Extend Field Day Rule Waivers from 2020, Add Class D and E Power Limit
02/10/2021

The COVID-19 pandemic-modified ARRL Field Day rules from 2020 will continue this June with the addition of a power limit imposed on Class D (Home Stations) and Class E (Home Stations-Emergency Power) participants. The news from the ARRL Board’s Programs and Services Committee comes as many clubs and groups are starting preparations for Field Day in earnest. Field Day 2021 will take place June 26 – 27.

“This early decision should alleviate any hesitancy that radio clubs and individual Field Day participants may have with their planning for the event,” said ARRL Contest Program Manager Paul Bourque, N1SFE.

For Field Day 2021:

• Class D stations may work all other Field Day stations, including other Class D stations, for points. This year, however, Class D and Class E stations will be limited to 150 W PEP output.
  

• An aggregate club score will be published — just as it was done last year. The aggregate score will be a sum of all individual entries that attributed their score to that of a specific club.
  

The attachment file is the Feb 09/2021 GBARC technical presentation.  The antenna I took apart was a 4 bay 70cm was the main soucre of photos and reference for the presentation.  The 4 bay unit did not have any 1/4 wave matching coax in the grounded feed arm of the folded dipole.  The 1/4 matching coax of a different impedance is used to make the antenna once completed a 50 ohm device.  Would probably be needed for the 2 bay or 1 bay antenna.  As part of phasing a multiple bay antenna, matching coax of different impedance may be needed but was not used on the reference 4 bay 70cm unit I used.

From the questions and follow-up emails, the info presented about the 4 bay diople appeared to be of great interest to those present.  I know for me it changed the way I thought how they were made.  If you were not there, you may find this interesting as well.

Cheers
