Get your winter gear on! The FYBO (Freeze Your B___ Off) Winter QRP Sprint, sponsored by the Arizona ScQRPions, is being held Saturday, February 4, 2012, from 1400Z-2400Z.

The rules are simple, and you even get multipliers for your (low) temperatures. Lots of fun, lots of QRP.

Read the full set of rules at the Arizona ScQRPions QRP Club website.

First photo of the Kenwood TS-990S?

UPDATE May 8, 2012: Want to see the real photo of the TS-990S? Check out this post.

The image above has been floating around the Internet for a couple of months as the concept for the Kenwood TS-990S. Is it the real thing? No. Absolutely not.

It is, without a doubt, a Photoshopped image. I ran an image error level analysis to see what parts were Photoshopped–see results below and follow this link to the full anaysis.

This analysis shows where Photoshop cuts and pastes were made--notice the areas highlighted in pink.

We will post TS-990S images when they become available from Kenwood. [UPDATE: see our most recent post with photo.]

Andy’s 6N7 Tube QRP Amp

In this Glowbug Times article, Andy shows us his very cool homebrew tube amp. Andy shares his motivation:

Once upon a time I’d decided to join a Big Guns Gang and made a Super-Duper Powerful Vacuum Tube QRP amplifier for my 800mW QRPP homebrew telegraph vacuum tube transceiver “3T” (I promise to write a separate article or two about this three tube transceiver project later). It was not an easy decision to me because for that legendary time I’d almost a year used the QRPPpower of less than a watt[…]

Building an Elecraft K3 in 7 minutes

This is a great time-lapse video of the assembly of the Midland Amateur Radio Club‘s Elecraft K3:

See, that wasn’t so hard!

Update: Ten-Tec should take orders for the Model 539 QRP transceiver at Dayton

Prototype of the Ten-Tec Model 539 QRP transceiver at the Ten-Tec 2011 Hamfest.

I just received the following from Ten-Tec:

We are progressing along per our schedule for having the 539 ready for orders at Dayton of 2012.

I have a hunch the Ten-Tec booth will be busy at the Hamvention this year.

Try your hand at Straight Key Night (SKN)

Photo courtesy: ARRL

For many, the CW event of the year is Straight Key Night (SKN). This is the time of year that you dust of the straight key and hit the bands with fellow hams who are using the most time-honored tradition  for sending CW.

Regardless of your sending and receiving skills on CW, SKN has a lot in store for you. Since this is a non-contest event, fellow operators are more patient with making contacts and more likely to rag chew. For many, this is the first time they’ve used their straight key since the previous year’s SKN, thus CW speeds are more comfortable for the novice across the band.

Straight Key Night is held every January 1 from 0000 UTC through 2359 UTC. 

The ARRL has a great article about SKN–check it out and get pumped for a full day of straight key bliss.

Ken’s PCB holder makes for a great weekend project

Thanks, Ken (WA4MNT), for bringing this very cool and simple project to our attention.

Click here to download instructions–parts are available from Ken for $23, or components can be home-brewed (I can imagine the plastic components can be replaced with wood).

Ham Radio Magazines now also available as a free download

Image source: VE3WGX

Just after we announced that 73 Magazine was available on archive.org as a free download, Ham Radio Magazine (1968-1990) is also now available. [Thanks to John AE5X (via QRP-L) and Eric WD8RIF for the tip!]

I cannot underscore the treasuretrove of information that you can mine out of these two publications. Both 73 and Ham Radio Mag have numerous articles related to home brewing, antenna design and low power operation.

What are you waiting for???  Christmas is here early! Go grab your copies of Ham Radio Magazine!

[UPDATE: It appears Ham Radio Magazine has been removed from Archive.org. Has anyone noticed if they’re still available somewhere online?  Please comment!]
