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!

Kit build came to an abrupt stop
Last weekend I was working on my Elecraft K2 project all was going well until I tried to clean my Weller soldering tip in the wire sponge. For some reason it the wire sponge was not letting the soldering tip go. It was as if the tip was soldered to the sponge that was supposed to clean it! I did free the tip from the sponge and I tried to clean the tip once again and the same thing happened but it was even harder to remove from the wire sponge. I then took a closer look at the Weller soldering tip and half the tip was missing, it seemed to have come off. I never had this happen in the past with these tips and of coarse it was this tip that I did not have a spare of. I did pick up some new tips (4 of them) and will now be able to continue with my Elecraft
K2 project once again. At one point I was using just a sponge that was damp to clean the tip's but I found this cooled the tips down and the soldering was affected. Has anyone out there ever had the problem of the soldering tips dissolving or breaking off in the wire sponge? The temperature on the Weller WES51 is set to around 800.

Have you ever been listening to something that may not be there???
Thought it was time this evening to power up the K3 and see what was on the bands. The software I use is DXLab and it comes with a spot collector as it's called. I noticed a spot for AX7GN on 20m so I double clicked on the spot and the K3 magically was there! So here I am listening for AX7GN and yes there is a station there calling what sounded like CQ....or did I want it to be a station calling CQ? Well I hoped it was not little voices in my head talking to me. I heard nothing so I just put my call out there....and listened just maybe a little to intently. I did hear what sounded like VE? VE? By this time the APF was on the RF gain was being adjusted and the filtering narrowed. I gave the call again at a deafening 5 watts!! Between the static and the ringing sound from the APF I thought AX7GN was giving out what "KINDA" sounded like my call.....or was it those voices again!! I passed along a 559 but did not hear much in return. To be honest I am not sure what the heck happened.....did I want to hear my call so bad that the static kinda sounded like VE3WDM?? For a short time I listened to the band and low and behold AX7GN was there and answering some U.S calls! I'm not going to put this one in the books as I am just not 100 percent it was just not the DX voices playing games with me. Has this ever happen to you??
The bandwidth on the Alexloop.
The next step in my Alexloop tests is the bandwidth in which the loop has. Again the antenna is mounted in a bedroom/office on the second floor of the house so that may have some affect on the SWR. I do plan on getting the loop in the out doors were the ceiling, walls and surrounding furniture do not have an affect on the loop. Below is the bandwidth results.
28.004 (SWR at 2.2) to 28.060 (SWR at 2.1) around 60 Khz of bandwidth.
21.020 (SWR at 2.0) to 21.070 (SWR at 1.7) around 50Khz of bandwidth
14.000 (SWR at 2.1) to 14.035 (SWR at 1.9) around 35Khz of bandwidth
10.110 (SWR at 1.8) to 10.125 (SWR at 1.9) around 15Khz of bandwidth
7.005 (SWR at 2.5) to 7.015 (SWR at 2.6) around 10Khz of bandwidth
I did however use the ATU on the KX3 and the SWR was flat when used on all bands so if I want I can use the tuner and increase the bandwidth of the antenna. I do know that my attic dipole on 10Mhz the SWR is about 9.1 to 1 and the tuner will flatten that out and I have made lots of milli watt contacts all over the world. So the next step is to get this antenna out doors and give it a whirl out there and see how it does.

Nice openings on 10m

EA2LU antennas |
I was now noticing some stronger signals, the first I tuned in was EA2LU from Spain. I tried Jorge with 500mW's and made the contact without any troubles. He was running a Yagi at 100 watts. This was a nice contact as we were able to exchange rig info, antenna info and

Announcing a new blog
Back in December when my second Elecraft K2 kit arrived I tossed around the idea of starting an additional blog about my K2 build. I planned to not only document my kit build but to keep the site updated with links and sites that will help out fellow builders. I have up to this point produced 3 pages and some updating posts on the blog itself. Check out the blog and give me your feedback as well as any info you would like to see on the site as well.
