RFI from new monitor

This evening I was on the radio and had the Elecraft P3 up and running as always. I just happend to be looking at the P3 external monitor when my PC's monitors went into sleep mode. I noticed that some signals (now seen as RFI) dropped off the screen. I had noticed these signals before and knew it was RFI but had

Both monitors off

 no idea it was coming from the monitors! My new AOC e2351F LED monitor seems to be the major culprit but the Acer Z233h does add just a little on it's own. If I turn the monitors off (via the monitor button) the RFI is gone or if the monitor goes into sleep mode. You can see from the picture to the right where the RFI was from the tails. So the question now is how does one go about narrowing this down? I have power supplies to each monitor...but would they be the problem if the RFI is gone when the monitors are turned off but supplies are still plugged in? Can you ground a flat screen monitor to my station ground? Could the RFI be traveling down the monitor cables? Well this is just another project to keep me busy. I am lucky that the RFI is not the same on all bands these shots are from 18mhz and it seems to be the worst of them all. Any ideas blog world??

Julie was out and about snapping shots!!

For me the ARRL  DX CW contest is over, I have some blog, email and cleaning to do for the rest of the day. Over all the contest was a success for me not that I broke any records with regards to points or number of contacts. I was very pleased with how the station and antenna were working, I find that contests are a great way to see how the rig and antenna preform. With regards to the rig and software I merged N1MM logger and N4PY rig control software through LP-bridge and as an added bonus I was able to also use the Flexradio's flex control vfo knob.....now that was a mouthful!! Lets break this down shall we N1MM is the

At 40mW and below this is the reading

contest logger that I use, N4PY is the software I use to control my K3. LP-bridge is a virtual port program that allows these two programs to somewhat talk to each other. I say somewhat as there are some minor issues. (there is another virtual port program VSP manager that allows perfect integration but I did not want to install it just before a contest) Oh and the FlexRadio FlexControl works fantastic with N4PY's rig control program and through LP-Bridge also works with N1MM as well. Another software program I ended
up purchasing was MRP40 cw decoding program. Now my code is not to bad at all but during contests I have found that for some reason some stations send at the speed of sound. (not sure why as they may loose more contacts that gain as folks just move on being not able to understand the fast code) For those stations this is were MRP40 shines.

Programs running during the contest

This is as far as I am concerned one of the best decoding programs. For those who want to participate in a CW contest but your code is not up to par this program will get you in on the action.  It's not free but is well worth the money!!

That was the software success for the contest other great events were being able to keep my power down to 1 watt....except for 2 contacts were the power creeped up to 3 watts. Did I say the power was kept to 1 watt? That was for a total number of  6 contacts the rest of the DX contacts went into the log with power numbers varying from 10mW's to 900mW's!!
Here is how the power numbers broke down
Contacts          Power
2                      10mW
13                     20mW
2                       40mW
4                       50mW
14                     100mW
22                     500mW
12                     From above 500 to 900mW
6                       1 watt
2                        3 watts

77                      TOTAL
I did say there was some records broken here at VE3WDM and they are
1. 69 DX contacts with under 1 watt in a contest!
2. Miles per watt bar is set higher.....CR3A with 10mW is 344,468 miles per watt 
                                                       DL6FBL with 10mW is 400,126 miles per watt

10mW on the QRPometer

I was not concerned about QSO per hour rate as at these power levels most of the time I had to try more than several times to make a contact. My radio equipment was (for those of  you wondering) the Elecraft K3, Elecraft P3, QRPometer, LP-100 meter, Hendricks 41dB attenuator and the last but not least the monster antenna......an attic dipole the Alpha Delta DX-EE.......that's right an attic dipole!!

In the thick of things

Well I am in the thick of things with the ARRL CW contest and as for my goals....I wanted to stay below 5 watts and try to get as many QRPp contacts as possible. Up to this point my QRPp contacts in the contest are at 92%!!! Because I am making mainly QRPp contacts the total contacts up to this point is suffering as I have to take the time to make the QSO. If there is even a faint signal coming back to the DX station I have to wait in line and sometimes these lines are over 5 minutes, this affects my total contact count big time. Some of the highlights up to this point in the contest are..........

1. Contacted DL6FBL with only 10mW's for a miles per watt total of 433,756 per watt an all time record  for me.
2. As was already mentioned 92% of contacts are QRPp and a majority of those are at or below 500mWs.
3. There are so far 9 contacts at or below 50mWs and again all these contacts are DX and not U.S stations.
 As for the rest of the goals like getting up early and racking up lots of time on the contest.........well the bed was sooooo comfee this morning it was very hard to get up and out before 8am! So that goal up to this point has not been met...but there is Sunday!! (dreams are free they say)
As for spending more time in the chair that will have to be weighted out on Sunday evening when the total time on air is looked at.
Contest on....it's off to 40m and maybe 80m as well..........will keep you posted

New monitor in place and ready for ARRL CW contest

Very dusty

This week a new monitor came in via UPS as my old standby monitor after many years of service bit the dust. I ended up ordering the AOC E235F monitor to match my other two 23 in monitors. Oh as a side note if anyone out there has an AOC monitor with a white square that shows up in the upper left hand corner shut off the picture boost bright frame option, which can be found in the monitors menu. Anyway.......With this nice new monitor up and running I did notice only one monitor seemed to be real sharp?? I then did some investigating and found out that my video care (Geforce 9400GT) had
one DVI and one VGA output port. It was the VGA port that was not allowing my new monitor to shine with all it's resolution. I ended up purchasing the Zotac Geforce GT 620 video card. This has two DVI outputs and as with the other care supports dual monitors. A small part of the day today was spend

removing the Geforce 9400 card and replacing it with the new Zotac GT 620 card. It was great to have the PC out and on the test bench I was able to give the interior a good cleaning. It's very surprising how much dust gets in there and to have the processor nice and clean and running cool will extend the life of the chip. The picture of the back of my PC shows many clip on toroid around most if not every cable as well there is a ground wire grounding the cabinet as well. I also put some snap on chokes on the DVI cable to the new monitor. This way my PC and monitors are RF free!

Working the KX3

OQ5A setup

On Friday I was able to take the opportunity to get some well deserved radio time in. Most weeknights when I get in from work and get the "house stuff" done I find I'm just to tired for the rig. On Friday I was able to fire up the KX3 and try my hand at some QRPp operationing. I was scanning up and down 20m's and found OQ5A from Belgium calling CQ. I adjusted the KX3 to 100mW's of power and gave OQ5A a go, he came back to me and with just a few repeats all the contact info was passed along and the QSO is in the books. This contact  at 100mW's netted me a distance of  37,603 miles per watt. 
I emailed Greet to let him in on some of the station info at this end. He was surprised I was only using 100mW's of power into an attic dipole to boot. Now here is the funny thing about propagation with 100mW's I tried to contact K0DNG in Kansas City Missouri and it was a huge struggle. I was going to up the power but Dennis was sending his 73s to me and moving on to calling CQ again.


Finally I saw on my Maclogger's cluster a spot for W0RW/PM now the cluster showed this to be in Indonesia. He was very weak and kinda in and out and there were other station trying to contact him as well. I topped up the KX3 to the 5 watt level and gave him a go. He came back to me and gave me a respectable report.  Now I thought there was something fishy about this cluster spot showing it as an Indonesian contact. I tripped off to QRZ.com and found out that PM stood for (in this case) pedestrian mobile!!  Paul was in Colorado which is a not even close to Indonesia...(this is my high school geography shinning through) but it was great making contact as I have read on many blogs about Paul and his pedestrian mobile adventures.
