Another AMAZING Homebrew Vacuum Tube (Valve)

I feel a moral obligation to put these projects on the blog every time I see one.  It just seems like the right thing to do.  Great work on the Pilotron.   Great workshop video also.  

Built-in Spectrum Analyzer in Hans Summers' QSX Rig.

I agree completely with the e-mojis.   Wow!  Cool!  I love it! 

Hans Summers is a genius. 

This is almost enough to make me get with the program and embrace SDR.  

Hans has done what seemed to have been impossible: true homebrew with SDR. 

First Audio From Mars

How long will it be before NASA starts getting critical comments on the audio quality, along with very confident statements about how to change the audio settings on the menu?  Well, at least they have "presence."

The Elser Mathes Cup awaits a winner!   

A Beautiful Launch! Watch the Video

Today's SpaceX Falcon 9 launch of Farhan's Exseed Satellite was really spectacular. Congratulations Farhan!  Really inspirational stuff. 

Now we wait to hear the bird.   If I have loaded the orbital information correctly, I should have my first chance this evening.   I have my antenna positioned.

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:
