BITX on the Beach in East Java (Indonesia)

Nobel Prize winner Joe Taylor, K1JT, Talks to a Radio Club

Really great to see this session with Nobel Prize winner Joe Taylor, K1JT.
I liked his comments on his use of his retirement office at Princeton, University. 
I also liked his slide on how far below the noise level you can go with various modes. 
And then there was his reminder to 1) RTFM and 2) be sure to check the EME delay box so that your software will get the timing right when working earth-moon-earth. 

"Pulsars keep good time." 

A Beautiful Variable Capacitor (from Pete)

Is this a thing of beauty, or what?   Pete sent this to me back when I was having trouble finding a "smooth running" variable cap for my HRO dial receiver.  It has a standard Jackson Brother's reduction drive attached to the shaft, followed by a really cool gear arrangement.  Note the spring loaded teeth on the big gear -- that is to keep the gears tight when turning in both directions.  

As was the case with the HRO dial that Armand sent me, the beauty of this part will cause me to build something with it, really just for the purpose of putting it to use. We've been talking about double or triple conversion superhets with 100 or 50 kHz final IFs.  At those frequencies you can get good selectivity with LC filters.  As with the Drake 2-B.    Steve N8NM is sending me a dial that will go well with this part.  That will add to the already abundant mojo/juju.  I feel a VFO in the works.    Thanks to Pete for being so supportive of my luddite analogism.  

Life in Appliance Land

"Sexiest Radio!"   Hmmmm.

"It's the bomb."

The 3D waterfall is kind of cool.    As is the big screen on the wall. 

Homebrew Your Own Remote Head (with a 3D Printer) (Video)

After I issued a luddite complaint lamenting the arrival in ham radio of appliance-like "remote heads", Ed KC8BSV pointed out that at least one guy -- Joe VE1BWV -- is HOMEBREWING his own remote head. (You must admit, this sounds really weird.) I still haven't completely got my head around this, but Joe's video (above) is really impressive.  

We're living in the future my friends!

Remote your heads!  With 3D printers!   

Our Dismal Digital Future?

I'm sure some would find this device appealing -- to each his own.   But I don't like it.   It seems to mark another step down the path toward the complete appliance-ization of ham radio.  Note how the control head is looking more an more like something for your car audio system, or your cell phone.  

YUCK.  

Count me out. 

Just say NO! 

Menus are for RESTAURANTS!  

RIGS NOT RADIOS!   

HDR FOREVER!
