My QRP signal is spotted in Europe!

I had some down time over the weekend and felt it was time to spin the K3's VFO and see what was out there. I started on 15m it really did not seem all that busy but I was hearing some German stations so the band was open. My Elecraft P3 is great as I was able to get a snapshot of the CW portion of 15m. This allows me to not spend time moving up and down the band blindly and maybe just missing some stations as they end their transmission. One could end up concluding the band is dead and move on when in fact they just missed a station or stations calling CQ and waiting for a reply.  I ended up calling CQ in and around the QRP watering hole at 21.060, in the past I have checked the Reverse Beacon Network (or RBN)  just to see how my QRP signal was doing. At this new QTH

for some reason I have been only able to get spotted in Canada and the U.S. To my surprise when I checked RBN I had been spotted in Hungary, Switzerland and Germany. I was very shocked and it kept me on the band calling CQ. Unfortunately there was no answers I then moved onto 17m and was spotted in France but again no answers to my CQ! I then ventured down to my standby band of 20m and found F5GPE Pierre calling CQ. His signal was in around 559 and I gave him a call and he came back to me with a report of 539. I did send him an email thanking him for the contact, he did get back to me giving me more details about his setup.

Rockmite

As I’m moving towards CW as an operating mode I took the plunge and bought a Rockmite kit from Kanga. Lets just say its not working quite as I had anticipated. This time I was very careful to look at the various instructions. Lid everything out and then checked every component as I assembled it.

2015-02-28 18.51.57Next time I’ll throw these things together in the usual manner. I might have a bit more success. Power on and I get little in the way of audio, a gentle hiss but not much else. So troubleshooting has to begin. Fortunately there is quite a bit of help for this but to be honest I’m not holding out much hope as I did such a thorough job of checking the first time round. Must be a faulty (insert component here) ;-)

 

All good fun and not as if the world will end if I have to spend some time on it.

ARRL CW Contest done QRP style

Oliver is asking……"Ahhhh dinner!!!
I took part in the ARRL CW contest this weekend in a part time way, I was not able to go full tilt as I had things around the house that needed to be done. I skipped the Friday evening as it's most of the big guns going at record setting CW speeds. I operated QRP, single band, non assisted, single transmuter and with my MFJ 1788 magnetic loop antenna. The bands were alive with CW and you would never think we were in the downswing of a solar cycle! Then conditions over all were great on 15m I was able to get on from early morning into the early evening. In the morning the bands were filled with
The rig setup
Europe and as the late afternoon rolled around the South Pacific started to boom in along with Central and south America. Some of the standout locations I heard were Bangladesh, Guam, Japan, New Zealand and South Sudan. None of which I was able to contact the pileups were HUGE!! Some of the highlights for me were contacting Hawaii, Cuba,  and grabbing a new DXCC Dominican Republic.
Score rundown is as follows
Contacts        DXCC's      Points
81                   39                9360

The equipment  used was the Elecraft K3 with 500,400 and 250 inrad filters, the Elecraft P3, Begali Contour Key and the Flex control external VFO knob and last but not least the MFJ 1788 Magnetic loop antenna. The software used were N1MM+ contest software, N4PY rig control software and MRP40 CW code reader for the chain saw speed code. I never had Murphy pay me any visits during
The contest software
the contest which really is a first time. I found 15m to be a great band very low noise floor and lots of action. I did venture up to 20m for a listen and from my location it was very noisy and I was glad I decided to stick with 15m.  Sunday seemed to be an easier day for making contacts I had far less repeats to do, Saturday I really had to work for each and every contact. Looking forward to the next CW contest!

Monday brings two dx contacts

Monday was a stay in and stay warm day oh and also I was able to fit in some ham radio time as well. Next weekend is the ARRL CW DX contest weekend and since I had time on my hands I thought I would finally install N1MM+ on my PC. Up to this point I have been using the older version of N1MM, the only time for me to update was just before a contest. According to Murphy's law if you update your contest software just before a contest bad things will happen! N1MM+ has some nice new features all of which I have not tried as of yet. While I was setting up and getting to know N1MM+ I had my K3 on and was rolling around the 20m band. I was able to make 2 DX contacts the first one being IK3VUT from italy. He was calling CQ and he came back to me on my first call to him. This was not your typically fast contact Luca gave you a report but also shared his name, thanked me for answering his CQ and asked my name. It was not a long QSO but it was nice to not just have a 599 and move on Luca gave me an honest 559 signal report.
late afternoon it was time to go out with Julie who had a photography assignment that involved us going downtown (Toronto) for some shots she needed to get. It sure was cold out but soon we would be back to our warm home and just a little more radio time as she edited some photos. This time on 20m  I heard HC5AI calling CQ from Ecuador and after some going back and forth he got my call and the contact was made.

It’s a cold one out there!

The little motor in the antenna
Today is supposed to be one of the coldest days this winter and up to this point we have had some very cold days! This morning I went out to get our food shopping done and going from the car to the market it was so cold it took your breath away. We live in a condo and in the underground garage the temp was -7C, most of the time it's well above 0C but not today. The temp this morning without the windchill was -22C and the weather is forecasting later later today with the windchill it  will drop to around -40C!! Today is a good time to stay indoors and play radio. The MFJ 1788 seems to have no problem in this cold weather. As a matter of fact the colder the weather be better the SWR, the little motor that operates the large capacitor has no problems in this weather. This afternoon I'm hanging out on 20m at the QRP watering hole of 14.060 calling CQ and listening. I was calling on 15m and it really did not seem like the band was open I then moved up to 20m. Since I was calling CQ I checked the Reverse Beacon Network and noticed that on 15m I was spotted by F5MUX from France. This is the first spot EVER for me from my new location being spotted  outside of the U.S. Well it's getting late in the afternoon and I was skunked on the bands today…..oh well maybe later this evening!

Middle East QRP contact

Back in 2012 I made my first and only to date contact into the Middle East using QRP power of 5 watts. The band conditions were good and 4Z5MU had not been spotted yet, this is also a great advantage to a QRP signal. Once the spot goes out the band gets crowded and the amps start warm up the QRP signal cools down. The other week his QSL card arrived and reminded me about the contact. As often happens when I hear a call and at the same time writing it down the rabbit ears go up when the result at the end of my pencil is a sweet DX call. One the first things that goes through my mind is "did I copy the call correct?" Once I realize it was copied correctly the next question is "where is the pileup" Now the game in my head begins……I now know this is a very sweet opportunity but I want to make sure they are not operating split and end up calling where I should not be! As I do this in the back of my mind there is a little voice saying "hurry up fool before the pileup starts and you loose the opportunity" This time the questions were answered and the opportunity of 4Z5MU made it into the log book and now a QSL card to boot.

Low cost kits

See http://www.aliexpress.com/store/331885 .   This website has some very low cost rigs for sale. An example is a 40m Pixie at around $10 post free. You’d be hard pressed to buy the individual parts for less!

UPDATE 1430z:   I have just ordered a 40m Pixie kit from them.  Should be here in 2 to 3 weeks time. I hope I can manage to build it with my clumsy soldering currently.

UPDATE 2000z: G1KQH has found the same Pixie at an even better price:
