Jason, the Argonauts, and QRP

You don't often find beauty in software read-me files, but I found some in those of I2PHD and IK2CZL. Take a look at this. It is from the read-me file for a Slow Speed CW program:
----------------------------
ARGO -- A QRSS Viewer by I2PHD & IK2CZL

Argo is program for viewing QRSS signals, i.e. very
slow CW, or DFCW signals, i.e. slow CW where dots and
dashes are of the same length, but offset in frequency
by a few Hertz, or even a fraction of an Hertz.

The name Argo is taken from that mythical ship which,
with the Argonauts on board, headed to Colchis,
in the quest for the Golden Fleece, much like the LF
Hams are in search of that fraction of dB of S/N which
will allow them to make that elusive QSO.

--------------------------

Here is where you can get the Argo software.
Free! And lots of other good programs

QRSs QRPp


I blame Hans Summers for this. His articles in SPRAT on very slow speed, very low power CW on 30 meters have caused me to develop a new set of Knack symptoms. I now listen intently to CW that is so slow that by the time I get to the end of a letter, I've forgotten if it started with a dit or a dah. I've become intimately familiar with the refresh rates of strange web sites known as "Grabbers" (I'd never heard of them before. See above for a sample.) And for the first time in my life as a radio amateur, using crystal control is no guarantee that I'm "in the band."

My 30 meter QRSs 200 mw "MEPT" beacon is on the air, but no one has heard me yet. This is almost certainly due to the fact that I'm probably outside the QRSs "band." This band is only 100 HERTZ wide! I'm using a 10.140 Mhz crystal, but the circuit values of my oscillator could easily put me out of that band. And Murphy struck: Just days before I started all this, my frequency counter died. My trusty Drake 2B is of little help in measuring frequency to this accuracy: The dial increments are 10 KILOhertz! And the 2B suffers from a problem totally unfamiliar to those who have grown up with glowing numerals: DIAL PARALAX! (It sounds like Knack-related disease, doesn't it? "I'm sorry m'am, your son Dilbert also has a bad case of DIAL PARALAX!!!")

Wish me luck. Don't blame me if you succumb to QRSs madness. Remember: it is all Hans Summers' fault.

DUGA-3 aka STEEL YARD aka WOODPECKER


Mama mia! Now that's an antenna! Put your HW-8 on that one and you'd be in business!
Here are some more shots of the Woodpecker antenna complex:

Jean Shepherd: KNACK VICTIM!

Guys, stop what you are doing. Put down that soldering iron, or that cold Miller High Life ("the champagne of bottled beer") and click on the link below. You will be transported back to 1965, and will hear master story-teller Jean Shepherd (K2ORS) describing his teenage case of The Knack. He discusses his efforts to build a Heising modulated transmitter for 160 meters. He had trouble getting it working, and became obsessed with the problem, obsessed to the point that a girl he was dating concluded that there was "something wrong with him" and that his mother "should take him to a doctor."

This one is REALLY good. It takes him a few minutes to get to the radio stuff, but it is worth the wait. More to follow. EXCELSIOR! FLICK LIVES!

The I-QRP Club Magazine

The Italian QRP Club (I-QRP) has a very nice quarterly bulletin. They have recently started to present a good portion of the articles in both Italian and English. The May 2008 edition is very FB, with many good articles, including one on impedance matching with broadband transformers.
Thanks to the I-QRP Club for making this available to hams around the world!

Here's the link:

Beacon Rig I0/N2CQR 28.240 MHz 1 Watt

Just a few shots of my new beacon rig. The first shows the Beacon Box on the shelf above the HW-8, attached to the battery. I've been running the beacon on solar power, using my two Volkswagen panels.

Here's a look under the hood: The larger board is a crystal controlled 1 watt transmitter (Dour DeMaw's ("Lil' Slugger"). The smaller board is K1EL's amazing keyer. I've left space for a 30 meter QRPp QRSS transmitter.

Finally, here is the "Sideswiper" aka "Cootie Keyer" I threw together in order to get my beacon message into the keyer. I discovered that I need a lot of practice on horizontal CW!
