New offerings

Some offerings:

The uBITX, or micro BITX - being offered at $109 for a limited time.

The uBITX is an HF transceiver capable of 10 Watts output on CW and SSB. It features a general coverage receiver, digital tuning, dual VFOs, RIT and a built in CW keyer.  It comes pretty much assembled, except for a housing and the user would have to hook up the controls knobs, speaker and antenna connections, etc.  Details can be found here: http://www.hfsignals.com/

It comes with open firmware and is designed to be hacked and experimented with. The original software is available online, so if you mess up you can go back to the default, easily enough. The programming language is Arduino C language.

The QRPGuys have also announced some new products:

1:1 and 4:1 voltage Baluns - http://qrpguys.apps-1and1.com/qrpguys-11-41-voltage-baluns

K8TND's 40 Meter Direct Conversion Regenerative Receiver based on a heavily modified Kitchin, N1TEV design. - http://qrpguys.apps-1and1.com/k8tnf-direct-conversion-40m-receiver

Note: W2LJ is NOT connected in any way with any of these companies - just trying to offer the latest news I come across to the QRP community.

In keeping with the Season

and the band conditions during our diminishing sun spot cycle, I will post a graphic that I saw on Facebook, courtesy of Jim Stephens NX8Z:


Last night's 80 Meter QRP Fox hunt was a tough go.  I finally managed to nab Randy NC4RT  in North Carolina for a single pelt.  Dave K5IX in Texas was a mere whisper, although my relatively close by neighbor Steve WX2S managed to squeak in a QSO in the closing minutes of the hunt.

QSB was tough, rapid and fluttery, and there was a low, whooshing noise across a part of the band that made things very difficult.  I'm not sure whether that was just local noise or some kind of over the horizon radar; but it was not pleasant to deal with.  I thank God for the Butternut, as it allowed me to snag the pelt.  Going against conventional wisdom, the vertical was giving me less noise than the horizontal wire!

Unfortunately, I think we have a few more years of this before things get better.  Maybe Santa will bring us some sun spots if we're all good Amateur Radio ops?

Fermi Labs Special Event

Fermi Labs celebrating their 50th Anniversary

https://www.symmetrymagazine.org/article/radio-lab


Don't get too close to the collider!

On a side note, one of the finest, most sleek looking Special Event certificates that I ever earned was when I worked the Oak Ridge National Lab in Tennessee during one of their milestone anniversaries. That one is framed and hangs on the shack wall to this day.
