Greetings to all readers, I am posting this to let you know about my progress with WSPR ( Weak Signal Propagation Reporter) .</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
I am running the Ultimate QRSS beacon kit for 30m band from Hans Summer G0UPL and Steve Farthing G0XAR it supports many modes one of which is WSPR,.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
The UQRSS is in the garage in a woolly sock at the moment because the cold weather alters the frequency outside of the 30m WSPR segment.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
The antenna is a homemade resonant 1/4 wave vertical, the radiator 7m long is at an angle of about 60 degrees in an NW direction and the 10 x 5m horizontal radials are in a fan shape of 45 degrees in a SW direction, the complete antenna is on top of the garage, the RG 58 coax is about 1m long and no balun is used.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
I am very happy with the results sofar.</div>

<br />
I have been trying out the W3EDP antenna which I have built, it is also known as a Zeppelin Antenna as it was trailed behind the Zeppelin Airships which is fitting because there is a Zeppelin Stone on the plateau to commemorate the fact that Graff Zeppelin was forced to fly over the Erpeler Ley during trials of his steerable Airship due to an approaching storm front.<br />
<br />
It is basically made of two wires one is 84 feet (25.6m) long (the radiator) the other 17 feet (5.2m) think of an OCF dipole, these then run vertically and parallel to each other for 17 feet in an open wire feeder configuration, (I use 17 feet of a comerical 450 Ohm open wire feeder) the longer wire (radiator) then needs to be vertical for another 6 feet (1.8m) I fix the open wire feeder and the first part of the radiator to a 25 foot roach pole and the rest of the radiator can be hung at an angle up in a tree or from another roach pole, add a 4:1 balun and an antenna matching unit ( I have the 4:1 balun connected directly to the AMU) and you are good to go as they say, you should be able to match this antenna to the 40 20 15 and 10 meter bands, I have only tried it on 40m to date with good results, people are amazed that I am running just 5 watts with this antenna, it can be put up in a couple of minutes, needs no trees and would also be a good antenna for SOTA operations, I have had this antenna up in some high winds and have not needed to guy the roach pole.<br />
<br />
I am also interested in portable digital modes and have built the Softrock RXTX ensemble by KB9YIG Tony and also the Ultimate QRSS tranceiver kit by G0UPL Hans, the softrock I built for 30 20 and 17m bands and has an output of 1 watt, the Ultimate QRRS kit I built for 30m band it runs off 4 AA batteries (6v) and has an output of 180 milliwatts the QRRS kit can also be used on WSPR (Weak Signal Propagation Reporter) as a stand alone transmitter with no PC required, for WSPR on the 20m band I use the softrock with an old laptop and a homebrew 20m band C-POLE antenna from HB9MTN's website, this antenna also fits on the 25 foot roach pole and again has not needed guying during high winds.<br />
<br />
I have had my very first WSPR spot into Australia on 40m on Sun 12/Aug/12 at 07:15 UTC with VK5EE Tom, running 1 watt and the C-POLE antenna from the Erpeler Ley at a distance of 16124 Kms.<br />
<br />
The Ultimate QRSS kit for the 30m band I use with a small homebrew magnetic loop (the Wonder loop) from G4ILO's website, I have increased the diameter of the loop from 80cm to 1.30m by bolting 4 x 1m long aluminium strips the kind you can purchase in DIY stores (use washers and self locking nuts so the loop can be folded into one 1 m length for transportation) , the loop is on an ordinary camera tripod and the QRSS kit can be straped to one the legs, just switch the QRSS kit on in WSPR mode then leave it alone all transmissions are automated, I have had a number of spots on WSPR through out Europe with just 180 milliwatts and the magnetic loop antenna, I also use this loop with 5 watts SSB on 40m and have QSO's into UK, Belgium, France, The Netherlands and once could be just heard in Norway.<br />
<br />
Its fun to have two WSPR modes and SSB QSO's all at the same time and the three antenna look very impressive and are a good conversation starter.<br />
<br />
Thank you for reading my Blog, I am more than happy to answer any questions, photos of the antenna to follow.<br />

<br />
I first tried the magnetic loop which has a diameter of just 80cm and had a QSO with Stefaan, ON2BS at 14:53 he was 57 with me I received 55 at a distance of 125 Kms (78 Miles), then at 14:58 with Christoph, DM5HF/P, he was 57 and I received 56 at a distance of 373 Kms (231 Miles).<br />
<br />
I then changed to the Hairspray can antenna, at 15:30 Jean, F8CHM, him 59, me 57, 583 Kms (362 Miles), 15:35, Peter G7FMF, him 57, me 56, 670 Kms ( 416 Miles) and 16:01 Mike, F5VIG, him 56, me 44 at a distance of 780 Kms (484 Miles).<br />
<br />
It was raining and some condensation got into the 360pF air varible cap on the magnectic loop, I noticed some flash over on the vanes which never happend when I was running 1.5 watts, I will have to think about sealing the plactic box for the mag loop, no condesation problems with the Hairspray can antenna, I will post some pictures later.<br />

<br />
Hi, when I am visting my in-laws in Münster I take my 40m and 2m portable setup which all fits into a backpack, included are a monoband transceiver (1.5 watts) from a kit from England (The Fivehead) and my trusty old FT 290R II (2m) which has been with me since 1986, the antenna I use for 40m are a hairspray can antenna from an idea by DL7AHW, G4ILO's Wonderloop (both for the 5th storey balcony of my in-laws flat), in the field I use a resonant 40m short dipole (each leg 8.23m and 2.44m ladder line) on a 7m roach pole from an idea by G3TKN (see QRZ.COM G1ZOS for photos), for 2m I use a rollup J pole antenna made from 450 ohm ladderline (balcony ant) and in the field a double quad SOTA antenna for 2m and 70cm from an idea by DL1JMS also on the 7m roach pole.<br />
<br />
My best contacts were using 1.5 watts on 40m and the hairspray can antenna, with GD4WBY Mike (Isle of Man) at 07:47 UTC on 31/12/2011 who gave me a 5/7 report he was 5/9, at a distance of 523 miles (841 kms) and IZ8FRH (Enzo) at 17:08 on 31/12/2011 he was 5/9 he had my callsign right but I lost him before I could receive my report from him, at a distance of 828 miles (1332 kms).<br />

</tbody></table>I went back to my home town for 10 days holiday and was QRP SSB QRV<br />
on 8 of those days, I had a number of contacts through out Europe on 40m using homemade equipment and running just 1.5 watts into a short dipole as inverted V (from an idea by G3TKN) on a 7m roach pole, my furthest contact was with IV3SUS, Savino at 07:43 UTC on 15/8/2011, my report was 5 and 3 and his was 5 and 5 at a distance of 1334 Kms. I also used my homemade hairspray can antenna for 40m and one for 80m,( from an idea by DL7AHW) my furthest contact with the 40m hairspray can antenna was at 07:05 UTC on 20/8/2011 with DL7MEF, Franz my report was 59 and his was 56 at a distance of 761 Kms with just 1.5 watts and a 50 cm long antenna, I am always amazed at how far I get with these two, the 80m hairspray can antenna has just been built and I had my first two QSO's with this on 20/8/2011 at 08:29 and 08:39 with GB2HLH and TM0LHG at a distance of 134 Kms and 113 Kms using 4 watts, the 40m ant has one hairspray can and the 80m version uses 3 cans.<br />

<br />
QRP to me is not just about the reduction of power output to 10 watts SSB or 5w CW, it is also about using simple homebuilt equipment and simple wire antenna, but if you are able to afford commerical equipment and multi element high gain antenna that is also good because it is the<span style="color: blue;"> <strong>QRP SPIRIT </strong></span>that counts, just reduce power and start enjoying the challenge of Ham Radio again, I would prefer a deckchair copy to an armchair copy anyday.<br />
<br />
I hope to be able to keep you up to date about my portable operations with locations photos and types of antenna used.<br />
