Setup for test. (Laptop running Ubuntu update)

The propagation conditions have not been all that great over the last couple of days so what a better time to do some on air Alexloop vs attic dipole comparisons! Here is the setup I used my Elecraft K3 putting the Alexloop in antenna 1 on the K3 and left the dipole on antenna 2 on the K3. This way I can use the internal tuner for the dipole and remove the antenna tuner for the Alexloop with just the push of a button on the K3. The power output was 5 watts, figured I would go to the top end of QRP considering the atmospheric conditions being not so hot. The Alexloop was up in my radio room facing West out the widow and East through my house walls. The Dipole is in a "Z" configuration in the attic so it kinda is facing most all directions. The Alexloop frequency was 14.061 and the dipole was 14.059 and I was using CW along side the Reverse Beacon network. The current atmosphiric conditions at the time of the test were:
A-5
K3
SFI 157
SN 173
Below is the results of the test.....not so well it would seem the Alexloop netted zero and the dipole only one. So is seems for a more acurate comparison better conditions are needed.

112 miles. 10,000ft of climbing on roads up to 30% gradient in the wind and rain of a very ‘normal’ West Cumbria. Fred Whitton Challenge. All 6 passes in the lakes in a day. Radio is a whole load less tiring, even when its not going well. Looking forward to getting back on the air

A few days ago my Fox Delta WX1 Micro Weather Station stopped working. As it turned out, I just had to switch off the power and switch it on and it started working again . But while I was waiting for the rain to stop so I could go out and look at the device I began thinking about getting a better weather station – one that measures wind speed and direction and rainfall as well as temperature, humidity and pressure.

When you start to look at weather stations the choice is overwhelming. My first priority was that it should work with APRSISCE and generate the file wxnow.txt that it uses to update weather objects. That requirement led to the stipulation that it should be compatible with the free weather software Cumulus, which creates the required file. There is a list of weather stations that work with this software, which narrowed the choice down a little. After reading many reviews the best choice seemed to be the Davis Vantage Vue. Unfortunately this cost about four times more than I was willing to pay, so it was back to the drawing board.

The weather stations made by the Chinese firm Fine Offset and sold under the Watson brand name seemed to meet my criteria at a more reasonable price. However, browsing through the reviews on Eham.net and elsewhere there were quite a high proportion of dissatisfied users. Complaints about anemometers that stopped rotating, poor wireless reception and so on. With weather stations as with everything else, it seems, you get what you pay for.

Despite the reviews I am tempted to get one of the Watson W6861 solar weather stations. But before I did I thought I would take the opportunity to ask my readers for their experiences. Many of you must have home weather stations. So which ones are good, which are bad and which should be avoided at all costs? I await your comments with interest.

It's always nice to get new toys. Toys are usually never in the category of "needed", but almost always in the category of "wanted". Over the past week I've had two new additions to the shack that are definitely "wanted toys"

I received the Begali Adventure paddle. What a work of art. This paddle is another example of the precision workmanship found in Begali keys. I installed the key on my KX3 (you must plug the key into the key port on the side of the radio) and it is pure joy to operate. So a KX3, with a Begali key, this isn't your your Dad's QRP. Most luxurious.

The key also had available hardware that will allow this key to be used with the KX1 and FT-817.

The weekend was busy, with lots of stuff to do in order to get ready for Mother’s Day, as well as actually celebrate it.  Even though I did not have much radio time, I did manage to get some time in behind the K3 and some good things happened.

The first good thing to happen this weekend was a package that arrived through the mail on Saturday:

Yes – my JARC Antenna Launcher Kit arrived through the mail. Thanks you Joplin Amateur Radio Club! This is going to be a tremendous help with portable operations this summer.

Late Saturday afternoon / early evening, shortly after my weekly Echolink ragchew with W3BBO,  Bob sent me an e-mail, letting me know that 15 Meters was wide open and that he had worked Z81X in the Republic of South Sudan.  I had just finished washing the floors, so I put down mop and bucket and ran down (literally) to the shack.  Sure enough, there was Z81X on 21.030 MHz, working split and sounding louder than all get out.  The pile up was tremendous!  So following my tenet of when the pile up is fierce and it’s a new one,  to  “Work ’em first, get ’em QRP later”, I turned the K3 up to 85 Watts.  After a half hour of chasing, I landed them in my logbook.  Z81X was like one of our wiley Foxes in the QRP Fox hunts in that he kept moving his listening frequency.  Once I established the pattern, and inserted myself in his path, it just became a matter of time.  Bob worked Z81X at 23:08 UTC and I got him a mere half hour later at 23:38 UTC.  Bob checked the on-line log this morning; and yep, we’re both in there. Sweet – a new DXCC entity for both of us!

Then today, I got some time this afternoon behind the dial and got two more new DXCC entities, and these I worked at QRP power.  15 Meters was hopping and netted me UN3M in Kazakhstan, as well as RI1FJ in Franz Josef Land.  The pile ups in these two instances were very small, so I tried QRP from the get-go here and was richly rewarded in both instances.  When the competition is not so fierce, you can afford to “be a purist”.

There was another station that I worked on 15 Meters that caught my ear, as it was a long and strange call sign – LZ1876SMB.  I have worked Bulgaria many times with QRP, but this was a Special Event Station to commemorate the Bulgarian Saint Martyrs of Batak.  A little Googling revealed that these were 700 members of the Bulgarian Orthodox Church who were martyred for their faith in an uprising against Ottomans in 1876.

If you go on QRZ, you’ll find out that LZ1876SMB is just one of many stations that will be on the air commemorating the Bulgarian Saints. For us Stateside ops, if we work five of these different LZ Saints Stations, a very beautiful diploma can be earned.

One down – four to go. I am going to keep my ears open for these stations. Bulgaria is usually (although not always) a fairly easy trip from NJ via QRP.

It may look like rain on the window but it's very much snow

It has been a week of not  much radio time and one of where you just seem to be spinning your wheels and not getting to far. In the evenings once dinner is done I am just to tired to hit the radio. The weather last week was great very warm and showers only now and then. The temp's were in around 24C dinners were BBQ's each night and even turning on the A.C was being considered. That was short lived when this weekend came

around and the temp's dropped. When I say dropped I mean it has gone from 24C last week to snow falling today and frost warnings for this evening. My Saturday was spent with Julie at the Metro Toronto ZOO.    We are about an hour and 20 minutes away from the zoo but this place is amazing and well worth the drive.

Sumatran tiger...seeing us as dinner dinner

Julie and I were there for 9 hours and we still did not cover the entire property. There are over 5,000 animals, about 1.3 million people visit the zoo each year. There are both huge outdoor exhibits and very very well done indoor as well. Julie was able to take 1500 pictures (and now is editing them) if you ever come to visit Toronto this is a must see venue. Here are some of Julies ZOO shots from our amazing day.
