Times R a changing

Times R a changing with the way the sun is preforming these days. I know we have all wanted the sunspots to go up along with the flux numbers......BUT..........what is up with the solar flares!!! As a wise man once told me with the good comes the bad as well.  Sunday afternoon I fired up DXlabs and on the cluster was S573DX from Slovenia. He was booming in at around S7 to S9 and I had my K3 at around 5 watts and so began my effort to contact him. There was a pileup and as it goes with QRP you have to let the big guns get their turn and then you can fit your call in the cracks! I was waiting for my
Back to the K2 build
opportunity (mind you I still was throwing in my call along side the "big guns"...you never know) and then S573DX went from S7-S9 so S...NOTHING!! In the blink of an eye he was just above the noise level even the APF was not able to dig him out of the noise floor. So goes the conditions when the sun grumpy! There are other projects around the shack to keep me busy...such as my K2 build. There was not much time for radio this week as Julie has relivitves coming in from England next weekend. They will be staying with us for 3 weeks so it was time to get some rooms ready for them and do some needed house cleaning as well.

Day one of CQ WW CW contest

Most of the time during these full weekend contests I don't get on Friday evening as I find it to be a ZOO with lots of stations sending at a blinding speeds. I don't blame them as they want to get their score rolling so that on Saturday they are well in the game. I started on Saturday morning around 8 in the morning the power output is 5 watts QRP into my attic dipole. It's funny I was sending serial numbers in the teens and I am receiving serial numbers the the triple digits. Now that would be depressing if I was in the contest to make a showing...but I'm in it to have fun!! So how did the first day go......
The facts
  1. The propagation was.....shall we say (because this is a family blog) crap!! 
  2. I was in the contest for a grand total of 5 hours today. 
  3. There was some down time as you can tell from fact number 2...software troubles, USB port trouble and K3 updates and the list can go on.  (This is normal contest OMG stuff)
  4. The attic dipole once again did very well considering the conditions.
  5. The evening once 20m closes down I am done as with the poor conditions for some reason 40m has not been a great band for me with the attic dipole. 
Day one surprises 
  1. So far I have not used any paper and pencils to copy call's I have been able to just use the keyboard. Now yes in the picture above in the center monitor bottom right you will see MRP40. (cw decoding program and the BEST one out there) That was up and running for the contester who for some reason send at @#@%$$# SPEEDS!! 
  2. With the propagation conditions in the dumps I was very please to get my QRP signal heard in Hawaii, Australia, South America and Cuba. 
  3. I have been practicing my contest code with some programs and for the first time code at 30-35wpm was clear and understandable! 
   So there  you have day one.......Sunday is another ball of wax! Good luck to all in the contest and to those not in the contest the bands will be your on Sunday evening.........just being a smart ass...:)))

Some time on the radio

EI9KC (2nd from left) and Anthony
Very rare during the week do I have time to get on the radio once all the things around the house are done I am beat... BUT this evening was an off night were I was able to power up the K3. It was 30m were things seemed to be happening for me. I was able to "hear" lots but contact few, there was lots of South American stations calling CQ but my 5 watts just did not seem to make it down that way. I had a look at the P3 to see what stations were showing up and I came across a very weak signal. I was not able to make out the call but then as 30m does the call came in at S5 just right for me decipher the call. It was EI9KC from Ireland now for some reason I do have a very hard time with getting Ireland in the log. I took a chance and threw my 5 watts out there and EI9KC came back to me! Ark gave me a 559 report and considering the band conditions, my attic dipole and the 5 watts I was pumping out I was thrilled! The trouble at this end was he was in and out BIG TIME! It was a very short QSO but I did email him just to make sure Ark knew I did copy him and I wanted to make sure he got my call and did copy me. He emailed me right back and did confirm the contact and low and behold he is a blogger as well. You can check out EI9KC's blog here, Ireland has a special place in my heart as both my mom and dad are from there. Funny thing and small world I did a search on Google regarding EI9KC and I found out he knows a fellow blogger Anthony EI2KC   (first ham on the left of the pic above).

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.

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!

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!

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??
