Launch Day! Godspeed Exseed! 1:31 pm Eastern time. Video links here.

Farhan posted this message and the above video to Facebook today (I have the video cued up to around the 5 minute point): 

We are all set for the launch of ExseedSat... There are two tiny switches at the bottom of the satellite that keep the satellite switched off while it stays in it's container. Once the satellite is ejected, the switches are released and the satellite wakes up. 
There are 36 satellites on this launch, some belong to close friends in the satellite fraternity. We wait for all the satellites to drift out and after 45 minutes, the antennas are depolyed and we will start beeping signals home.
Here is a test of that process. You can skip to the fifth minute to watch the antenna depoly .

I really like the tape measure antenna.  This recalls the earliest OSCAR satellites.  And let's not forget that OSCAR 1 also launched from Vandenberg.  So there a lot of good tradition flying with Farhan's bird. 

Press reports indicate a launch time of 1:31 pm Eastern time today.   I think you can watch it live through the video window below.  Or try this link:

Totally Absurd -- Farhan Being Questioned in a Police Station

I walked into the shack this morning hoping to read good news about the InSight landing and the impending launch of Farhan's satellite, but instead I found this message from Farhan in a police station.   This is really absurd and disheartening.   Someone (not Farhan!) altered the Indian flag and put it into an image of Farhan's CubeSat.  So with 24 hours to go before the launch, our friend Farhan finds himself in a police station. 

Stay strong Farhan!  You have a lot of support around the world.

Falcon 9 Cubesat Launch Now Set for Wednesday

It looks like the Falcon 9 with Farhan's CubeSat is not scheduled to launch this Wednesday between 1030 and 1100 West Coast time.  Above you can see a similar launch.

The Max Valier Satellite Flies Over, Sending CW

I understand the launch of Farhan's CubeSat has been delayed a few days.  That's the way it works in the rocket launch biz --patience is required.  In the meantime, I've been practicing with my receive system.  Today at 1000 local the Max Valier satellite flew to my west.  It rose 78 degrees above my horizon to the W NW.  I left my three element quad pointed in that direction and waited for the satellite (which had been launched from India) to fly through its pattern.  

The CW beacon was quite strong, very visible and audible through my RTL-SDR dongle and HD-SDR software.  You can see it and hear it in the video above.  There is something quite charming about this very personal Morse message coming down from orbit and then passing through all that digital technology.   

More info on the satellite: 

"Max Valier Sat" is an amateur satellite built in cooperation by:

• "Max Valier" High School in Bolzano/Bozen (Italy)
• OHB System AG from Bremen (Germany)
• Max Planck Institute for Extraterrestrial Physics from Garching (Germany)

Its main payload is an X-Ray telescope devised and made by MPE. Data generated by this detector will be transmitted, together with housekeeping data, over an amateur radio link with frequency 145.860 MHz.

A second payload is an amateur radio beacon transmitting a message in Continuous Wave. The beacon's frequency is 145.960 MHz

"Max Valier Satellite" was launched by the Indian Rocket PSLV-C38 on June 23, 2017 at 9:29 am IST (05:59 am CET) from Satish Dhawan Space Centre.

Regarding the CW beacon: 

Beacon by Holger Eckardt DF2FQ:

• Transmit frequency is 145,960 MHz (IARU and ITU coordinated).
• Modulation is CW:
• Duration of one dot is 114 ms.
• Duration of one dash is 342 ms.
• Interval between words is 1881 ms.
• Interval between repetitions of the message is 6000 ms.
• The beacon transmits Max Valier Sat's call sign and a greeting message.
• Transmitting power is 500 mW.

And who was Max Valier?  Quite an interesting fellow:

Launch Date Approaches for Farhan's Satellite

It looks like the launch date might have been moved up from 24 November to 19 November. 

W7ZOI: Direct Conversion Receivers -- Some Amateur Radio History

http://w7zoi.net/dcrx68.pdf

Farhan and Pete WB9FLW alerted me to this wonderful article by Wes Hayward, W7ZOI.  I guess my interest in DC receivers must have been noticed by the Google algorithm because I am bombarded by ads extolling the virtues of "Zero IF."   Hey Google -- I'm already a believer!  I was converted by W7ZOI's 1968 article in QST. And my belief in the technique has been greatly reinforced by his November 2018 50th anniversary article. 

There is so much good stuff in Wes's look-back piece.  The travails of trying to write for QST are presented very well.   And we learn that none-other-than Doug DeMaw himself is responsible for the use of the word "presence" in describing amateur radio audio.  

This article has inspired me to take a new look at the DC receiver I built last winter.  Mine needs some work. I think it is kind of deaf.   It could probably benefit from a diode ring  detector.   But it already has presence.

Thanks Wes.  And thanks to Farhan and Pete for the heads up. 

1972 Solar Flare Caused Naval Mines to Explode

There are reports out this morning that a big solar flare in 1972 caused naval mines placed by the U.S. off the coast of Vietnam to explode.

Getting Ready for Farhan's Satellite (videos)

I've been getting ready for the November 24 launch of the CubeSat that Farhan and his friends in India built.  I started out with my trusty Drake 2-B and a Hamtronics 2-to-10 downconverter, but I quickly switched to an RTL-SDR dongle and HD-SDR software.   My 3 element quad antenna is visible in the first video.   So far, I am using the Armstrong method to turn the antenna. 

In that first video I keep saying that I am waiting for AO-71.   In fact is was AO-73, the "FunCube" from the UK.   I think it is similar in power and antenna configuration to Farhan's satellite, so I think we are almost ready for launch.

(Any ideas on what that mysterious pulsating sig in the satellite passband signal is in the first video?)
