Propagation
is a fascinating subject. It affects us all, is discussed at length on
QRP-L, but is understood by few ! Just what does that Storm graphic
mean ? That's bad isn't it ? Er, or is it good ? What about that
K-index - or should we use the A-index ? Just what do those numbers
mean anyway ?

Harden NA5N is one of those rare individuals who really understands his
subject and has a talent for explaining in a way we can all understand.
He's also a whizz at presentation. This feature is set to become a
classic, full of hints and tips - you will become your local club's
propagation guru !

 If you haven't come across it, you'll want to check the website of Phil Salas, AD5X. It's www.ad5x.com of course. Phil's site is frankly not much to look at until you dig deeper! In case you are not aware, Phil (ARCI# 7497) was recently awarded the 2005 Bill Orr, W6SAI, Technical Writing Award. That's because he has had numerous articles in QST over the past few years. When asked about his articles, most folks say that they like'm because they actually feel like they could duplicate what Phil has developed!

| QRP ARCI Hall of Fame members, N2APB and N2CX, have announced the availability of a new partial kit for PIC-EL experimenters. This follows several runs of their popular pic-el kit, usually referred to as a "pic-kle". Partly due to the ongoing popularity of John McDonald's Elmer 160 online course and a growing interest in pic-el applications in the ham community, the AMQrp club will produce a partial kit for expermenters. |

Back in 2002 my then 7 year old son Austin wanted me to help him build a radio. At that time I helped him build a cigar box crystal radio set.
He enjoyed that radio but since then he has taken a liking to CW and
his simple cigar box set would only receive AM. He wanted a receiver
that he could help build yet would receive CW and voice (AM/SSB) and on
top of that it had to have a built-in antenna so that he could take it
places and/or keep it by his bedside . . .

I enjoy taking my QRP gear to the field and operating but it can sometimes be difficult to come up with a decent antenna for such work. I have used many types of antennas but I prefer antennas that can operate efficiently without any connection to the lossy ground or that require an extensive radial system. The type of antenna described here has always performed well for me and is easy to adjust for a good match no matter how you erect it . . .

My PIXIE interest started about two years ago when I was looking
for a simple transceiver to be built by my builders group that would
give a successful contact among the members and provide an effective
tool for exploring the art of building a working radio. Here I'll
outline what I've done with the PIXIE and where you can find out more
if you want to build a PIXIE.

 It seems that Bas, PA5BAS of Gorinchem, Netherlands is very excited
about his new Rockmite 40. On the yahoo.groups list called
QRPp-l, he outlines how he built his Rockmite from Small Wonders Labs
with a Euro 7030 khz crystal and has been making some great
contacts. Even has one QSO that is good for
1000KM/watt!
You can see some great pictures . . .
