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
- The propagation was.....shall we say (because this is a family blog) crap!!
- I was in the contest for a grand total of 5 hours today.
- 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)
- The attic dipole once again did very well considering the conditions.
- 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
- 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!!
- With the propagation conditions in the dumps I was very please to get my QRP signal heard in Hawaii, Australia, South America and Cuba.
- I have been practicing my contest code with some programs and for the first time code at 30-35wpm was clear and understandable!
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!

230KV lines out back |
MFJ 1026 noise canceling unit…for today ham!
Things don't seem to work when you really need them |
Nice openings on 10m
Signals on 10m this afternoon |
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

Seems doing nothing is doing something…..
RFI Friday night |
1. I changed out the video cables and wrapped them with chokes as well.....did nothing.
2 Moved the monitors to other locations on the operating desk...that was loads of fun and it too did nothing.
3. Tried running the K3 just off battery power and.... nothing.
4. Ran the monitors from the 12 volt Astron power supply and again nothing.
5 Put snap on chokes on ALL cables coming out of PC and the ALL cables from each monitor.....NOTHING!
6. Even tried tin foil on the back of the monitor and grounding it...only made monitor look sci-fi.
7. Put 1:1 balun on the coax coming out of the K3 and still had problem.
8. Tried my Elecraft K2 (maybe just a K3 problem) found same issue with K2.
Sunday...not to bad |
9. Plugged monitors into separate AC outlets on different circuits and did not fix issue.
10. Ran a ground up to each monitor and video card on the PC (PC is already grounded) and nothing.
11.Repositioned screen to see if that made any difference I thought it did but turned out not to.
So that was how my Saturday was spent and from doing all the above I was able to find out a few things that I hope may ring a bell on how to solved the RFI isssue
1. As I move my hand closer to the monitor the RFI increases.
2. When the rig is on the dummy load the RFI is gone.....but so is everything else regarding signals.
Now it's Sunday and I have come to the understanding that I am going to just have to live with the problem. I know where it is coming from that sometimes that is half the battle! I am going to do some reading and thinking about the issue. I came into the shack to just roll the desk back up against the wall and tidy up the room. I then turned on the K3 along with the PC and for some reason the RFI is still there but not as much at all!!! Seems doing nothing is doing something!!
Monitor RFI issue…..
RFI from new monitor |
Both monitors off |
