"So You Want To Build?" Words of Wisdom from Pete Juliano

Everything on Pete's blog is worth reading, but this article was so good that I could not resist posting a link to it here. 

Tribal knowledge from a leader of the homebrew tribe:

AE7KI (VK2APG), FT8, and WAS on a BITX20

I've had several very nice conversations with Gerry AE7KI (aka VK2APG).  His Australian accent sets him apart from the other Tennessee stations.  Last time we talked Gerry mentioned having competed Worked All States with his BITX20 (below). Very cool.

Gerry also alerted me to a new digital mode created by Joe Taylor.  This one is called FT8.  Gerry is using it to good effect on the 6 meter band. Here is Peter Marks' initial reaction to FT8:

As I type, there are 252 stations monitoring 6 meters for FT8 signals.   You can see a map displaying these stations here:

Yellow Fever! The Cold War Origins of Juliello

How could you miss them?  That yellow was bright!  Apparently you needed high visibility to cope with the looming danger of nuclear annihilation.  The operator in the ad is obviously calm in the face of Armageddon -- note the cigarette dangling from his lips. In this 1956 Gonset ad we can see the inspiration behind what -- many decades later -- has emerged as the avant-garde ham radio color scheme known as Juliello.  The roots of this aesthetic are clearly not in the psychedelic "Mellow Yellow" hippie era.  No, this color has harder, more flinty origins.

Pete Juliano is not the only one to embrace this look.   Podcast #198 elicited this response from our friend Armand WA1UQO: 

Pete:
Don't let that Meara guy give you a hard time over the yellow Rigs.  The last three of mine have been yellow and I'm happy to see I'm not the only one with good taste.  In the picture they are from top to bottom a 30M One Watter, a 20M One Watter and of course the BITX 40.  The 20M does have a Juliano Blue cover though to give it an extra bit of class!  As always, enjoyed the podcast.
Bill,  see you at Berryville?
73, Armand WA1UQO

Juliello.  No. 

Ralph Baer -- Video Game Inventor

Thanks to Stephen G7VFY for alerting us to this very nice video.   Ralph Baer did pioneering work in video games.   It is fun to see him in his workshop. He obviously has a variant of The Knack.  Stephen hinted at a reference to "noodling" but I didn't hear it -- perhaps Stephen meant that the whole thing was about what we'd call noodling.  I found the box on his bench labeled "Wire Wrap Materials" kind of ominous -- remember our April 1 announcement about the launch of the new "Wire Wrap Rap" podcast?

I liked Ralph's summary comment about how these days he just has fun building things.

KC8WBK's Cakepan BITX40

I talked to Paul KC8WBK last night during the regular 7277 kHz Sunday night BITX gathering (7 pm local). I like his BITX enclosure.  Very practical and economical.  It provides ready access to the circuitry.  He also has nice enclosure for the microphone and push-to-talk switch. He has more info on his QRZ.com page.
