3D Printing Is Not Magic
Despite some of the challenges, I still think there is a lot of potential in 3D printing. It's not like the internet started out with wireless tablets and other magical sci-fi tools. Give it some time. I remember when I was a geek since I had a (wired) network in my home. Now grandmothers' have networks and preschoolers zip around iPads.
Leixen VV-808
N9XLC has posted about the VV-808 transceiver. As he points out, this thing is small. I'm guessing from the pictures and the box that the manufacturer is Leixen, but there is no name on the radio. And we all know how these things get re-branded. The radio itself is $71 USD, but shipping is almost the same.
I'm going to assume the description of 136-174MHz or UHF: 400-470MHz is true and it is a mono-band radio despite some fuzzy language in parts of the listing. DHGate gives these specs:

Ten-Tec 506 Rebel
A sneak peak of the new Ten-Tec Model 506 Rebel - an open-source CW QRP transceiver for 20 or 40 meters at the qrper.com:
"The TEN-TEC Model 506 Rebel is an open-source (meaning, anybody can program it), factory-built QRP transceiver based on a Chip Kit Uno 32 Arduino-compatible prototyping platform, which serves as the main processing unit that holds the Rebel’s program. (For those of you not familiar with the Arduino series, check out this article.)
And I have to admit, I love the concept: TEN-TEC delivers a factory-built, uber-simple transceiver, with just enough programming to reliably get you on the air with a basic radio (see details below). Users then have full access to develop and program the Rebel via an open-source platform, themselves. No need to wait on firmware revisions; firmware, in a sense, will be crowd-sourced! That’s to say, it uses online collaboration–a great idea."
No surprise - it has a Yahoo Group.

What's in a name?
harrymccracken I love the fact that Windows Blue’s official name is Windows 8.1. I hope there’s a Windows 8.11, too. But not for workgroups.
