Venerable AO-7 Satellite

The nearly 46-year-old AO-7 amateur satellite made a remarkable contact possible on May 4 between Diego Feil, LW2DAF, in Buenos Aires, Argentina (GF05rk), and Tom Ambrose, ZS1TA, in Cape Town, South Africa (JF95fx). The contact spanned 4,329 miles across the South Atlantic, with both stations aiming at only 2 or 3 degrees above the horizon.

Both stations had been watching orbital predictions for several weeks, and times when both stations could “see” AO-7 at the same time occurred only occasionally. Electrical noise, particularly in Cape Town, had hampered earlier efforts, but on the morning of May 4, noise levels were low, and a perfect contact was possible with full call signs and reports exchanged.

In 2016, Dave Swanson, KG5CCI, in Arkansas, and Eduardo Erlemann, PY2RN, in Brazil, achieved a distance milestone on AO-7, completing a scheduled contact that covered a calculated distance of approximately 4,979.2 miles, which Swanson said was “way beyond the theoretical range of AO-7” and a feat that “the math said shouldn’t be possible.” — Thanks to AMSAT News Service

Hot Spot on Keystone West Room

Click on Image For Full Size

We are currently working on adding a link to the Keystone-West Room.  This will let users using a MMDVM Hot Spot or any other model to get access to the Keystone-West network. Stay tune to this website when it goes active.  Temporary we will be linked to “FCS00315” Pittsburgh-Pa-Digital-Group but hopefully will be moved to its own reflector. So if you are not close to any of the Pittsburgh you could pick up an Hot Spot {Example here} and create your own like to the Western Pennsylvania C4FM System Fusion network.

Hello are you missing all your friends up at the club house? Well This Wednesday night at 8:00 PM sharp we will try out our first virtual social meeting. Like our normal social meeting there is no set format  for the meeting just friends getting together to jabber the night away.

This past weekend the technical committee tried out the software and what was suppose to be just a short test but it work so well we used the software for two hours. Doug W3HH show us his shack and how his person SDR radio worked.  Karl WA3VXJ show us some of his old antique radios. The the stories flowed the whole night.  I was able to show off RemoteHams software to the whole group while they were all able to ask questions about how to use it.

This is what the invite will look like – Just click on the link in the message

So you now wondering how to join in on the fun.  First of all there is nothing to install on your computer. All you will have to do is to check your email for the Zoom Meeting Invite which I will be sending out around 7:45 PM Wednesday.  Once you open the email you will just have to click on the link inside the email. This will install a very small program in your browser once that little program is install the Zoom Window will open up and ask for your name.  I would recommend using your First Name and Call Sign. Now the meeting will open up and you should be able to see what is going on.   You will most like need to click on the MICROPHONE icon at the bottom of the screen to turn your microphone on.  The first part of the meeting I will be going over how to use the software.

So what equipment do you need to make this work.  You will need either a Desktop Computer, Laptop, I-Phone, Android Phone, Window or Mac are ok.  The second thing you will need is some sort of microphone plug into your computer. If you have a headset for the remotes that would be perfect for the Zoom Meeting.  Now your computer should have a Webcam {While its not required it is nice to see your face other wise the screen will just show your name} If you have a desktop computer make sure the webcam is plug in. {Dont bother looking to buy one the $40 ones are going for $100 and they are still out of stock.}   Now most laptops have webcams built into them along with a microphone. The webcam is a small hole above the computer screen.  And all I-Phones and Android phone have camera now a day.

Now if you what you show us your shack pictures, an interesting webpage, or your favorite FT-8 program make sure you have those open before you start the Zoom Window.  That way you can click on SHARE THE SCREEN icon at the bottom of your window to select which ever Windows screen you want to share out to the group.  This program has been very interesting in how it lets many people join in on the fun.

MEMBERS: Please make sure your on the [W3KWH Group] email reflector.  The invite will be sent out only via the email reflector from my N3LRG gmail account.

 

WLS RADIO 890 KC

The Sears & Roebuck Co. founded WLS ( WORLDS LARGEST STORE) on April 12,1924. In 1938, the station’s transmitter was moved to Tinley Park, Illinois In 1931 and the station’s power was increased from 5,000 watts to 50,000 watts using a RCA 50 kw transmitter.

The 50F even had a door that you could walk through to get into the transmitter from the front. Here, the door to the power supply section is open.

Transmitter site Tinley Park, Illinois

Ralph Beaudin was the station’s president and general manager, and oversaw the station’s transformation into a rock and roll / top 40 station.Sam Holman was the station’s program director and an afternoon DJ. Beaudin and Holman were both brought in from KQV in Pittsburgh, Pennsylvania. Could of been our own Joe WB3AGB !

The station also experimented successfully in many forms of news broadcasting, including weather and crop reports. Its most famous news broadcast was the eyewitness report of the Hindenburg disaster by Herbert Morrison. Morrison and engineer Charles Nehlsen had been sent to New Jersey by WLS to cover the arrival of the Hindenburg for delayed broadcast. Their recordings aired the next day on May 7, 1937, the first time that recordings of a news event were ever broadcast.

Herbert Morrison born May 14th, Connellsville, Pa. In 1905 best known for his dramatic report of the Hindenburg disaster, a catastrophic fire that destroyed the LZ 129 Hindenburg zeppelin on May 6, 1937, killing 36 people.Morrison served in the Army Air Corps during World War II and became a radio reporter and the first news director at WTAE-TV in Pittsburgh. He ran for Congress three times as a Pennsylvania Republican during  the 1950s.

 

United Nations Amateur Radio Club

From the ARRL.ORG website

The president of the United Nations Amateur Radio Club, James Sarte, K2QI, reports that during the UN Headquarters building lockdown as part of the “Stay Home” mandate, the club’s 4U1UN has been granted permission for “very limited” remote operation on FT8, only running low power. Fox/Hound mode is part of the mix. Operation on 40 and 20 meters was reported on April 12. — Thanks to OPDX via Southgate Amateur Radio News

JS8Call now supports APRS over HF

JS8Call is an experiment to test the feasibility of a digital mode with the robustness of FT8, combined with a messaging and network protocol layer for weak signal communication on HF, using keyboard-to-keyboard style interface. JS8Call is heavily inspired by WSJT-X, Fldigi, and FSQCall and would not exist without the hard work and dedication of the many developers in the amateur radio community.

JS8Call is a derivative of the WSJT-X application, restructured and redesigned for keyboard-to-keyboard message passing. It is not supported by nor endorsed by the WSJT-X development group. While the WSJT-X group maintains copyright over the original work and code, JS8Call is a derivative work licensed under and in accordance with the terms of the GPLv3 license.

Trans-Atlantic contact made on 432 MHz

On Tuesday the 7th of April 2020, a remarkable contact was made with the FT8 digital mode on 432 MHz between D4VHF on the Cape Verde Islands off the coast of Africa and FG8OJ in Guadeloupe in the Caribbean.

This was the first 70cms trans-Atlantic contact without using satellites or the moon. The most likely mode of propagation was marine ducting with the signal being trapped close to the ocean.

This is a screen shot showing the FT8 contact which was approximately 3,867 kms in length.
