Thermatrons Al Fresco: W4GON's FB HB AM Rig

I was listening to 7290 kHz with my BITX this morning and I heard W4GON say his AM rig is homebrew.  So of course I fired up the DX-100 and the HQ-100 and gave Joel a call.  Conditions were terrible but we had some support from the radio gods.  

From Joel's QRZ.com page: "It uses a pair of 6L6s in Push-Pull Class AB1 high level plate and screen modulating a 6146. I still have a lot of work to do on this rig, like building an enclosure, but it works and I just couldn't help but getting on the air with it!"  

I think it is a thing of beauty.

"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.

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?
