Dayton = NEW STUFF!!!!

This is a great idea from Ten-Tec which was introduced at Dayton....I give you the QRPer blog he has done a stellar preview. Check it out and get the grey matter excited!!

Alexloop vs Attic dipole

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.

A weekend of fun and then snow!!

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.

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.

Short time on the radio netted 37,968 miles per watt contact.

Last evening I had a very short time on the radio I was not expecting much as the conditions have not been stellar. I did find 20m to be very busy and not reflecting the solar conditions. On May 2nd I was able to work EA4DRV and last night I heard him on again calling CQ. I gave him a call and made the contact with only 100mW's for a miles per watt of 37,968! Shortly after my contact I heard him giving a report to fellow blogger Larry W2LJ. I was only able to hear Larry very faintly just above the noise level. I did do a little more fishing but time was tight and I had to shut things down for the evening. This evening I think I am going to throw the line out again and see how the fishing goes!

The weather once again was great and I wanted to take the Alexloop out onto my back deck to see  how it would do once again. The other day I had no spots at all but this day was a complete different story. I was operating  my KX3 at 3 watts. The antenna as was already mention is the Alexloop mounted on a tripod. I called CQ on 20m,30m and 40m it was the late afternoon and nothing could be heard at my end at all. I was spotted only in the States but conditions have not been all that great. I did hear some American stations on 30m but they were just at the noise level. By the spots on the Reverse Beacon Network my signal is getting out! I am excited to see how this antenna does once the condition improve.

A nice way to rest a sore back.

Relaxing on the deck.
Last evening myself and a bathroom mat had a little hip hop time.....translation.....I was standing on a bathroom mat lost my balance causing me to "hop" and out went the hip!!! Today it was no work, off to the Chiropractor and physio. The good news is no disk problems just muscle but I still have to be very careful as I do have lower back disk issues. So what does this have to do with ham radio....nothing....BUT this does...It was a very nice sunny day out and I wanted to relax on the deck and not become board, so I gathered up (very gently) the KX3, Alexloop, Sony MDR-V150 head phones and a pad of paper.

Some things I tried with the Alexloop
1. I emailed Alex regarding his opinion about adding some extra coax so I did not have to be that close to the loop. He (as always) emailed me back within 10 minutes explaining there should be no problem doing this. At first I did try 12 ft of RG 213 and found I could not get a decent SWR. I then tried a 6ft piece 
and all was well. This would allow me to sit at the patio table and not have the loop under the patio umbrella.

2. When tuning the loop if I was in front of the loop while adjusting it's capacitor I found I could get a 1.2.1 match on 20m..but..as soon as I moved my hand away from the loop the SWR rose to 2.1.1. I found by adjusting the loop from the back of the antenna the SWR was not affected. 
New loop to tripod adapter

3. In the past I was using plastic zip wraps to attach the antenna to the tripod. I made and wanted to try a new antenna to tripod holder made of plastic pipe and heat shrink. It turned out to work just fine and will allow me to set the antenna up much faster in the field. 
 
I called CQ on 14.060 for about a 1/2 hour and was not spotted on the Reverse beacon network. This does not concern me as conditions were not that great. It was not my plan to really make any contacts but the see how the loop fit on the deck. Also how the new adapter I made fit both tripod and Alexloop.  Regarding the Reverse beacon network not sure if it is up and running properly today. I tried to refresh the spots and it seem to get stuck trying to refresh.

Poor conditons but still worked a few…………..

Throughout the day yesterday I was getting propagation updates on my Iphone, things were not looking to good. The decision was made to work on my Elecraft K2 build and not get frustrated with poor propagation conditions. After about 20 minutes of working on the K2 I just was not getting into. Putting the project down for the evening I flipped on the K3 just to check out the band conditions. One of my handy tools for doing that is the Elecraft P3. It's great for seeing the general condition of a particular band. It seemed that 20 meters was not doing to badly considering the conditions. The first station I ran across was H70ORO from Nicaragua. His signal was rather strong considering my attic dipole does not seem to favour Central or South America. His code speed was a comfortable 20 wpm and really not much of a pileup. I made contact with only 1 watt which gave me 2,190 miles per watt contact.
The next (and final) station I contacted was EA4DRV, being pumped from my last 1 watt contact I tried working this Spanish station with 1 watt. It didn't work out as well and the contact was made eventually with 3 watts. After this contact it was time to flip the switch once again and move on to making lunches, arranging morning work clothes and all that other fun stuff.  It goes to show you that even when the propagation is in the dumpers contacts are still there to be had!
