M class solar flare letting go
It's Saturday afternoon  around 3:15 local time and 19:15 UTC I just finished turning the Elecraft k3 on for the 3rd time today and nothing!! I looked over at my LDG antenna switch to see if I was on the dummy load but no the attic antenna was connected. I turned on my Elecraft P3 and it was almost flat lined hardly any signals to be found. I try not to use propagation alone to judge the bands as in the past propagation conditions have not been good but I had made some great contacts. Well it was time to head off to Solarham.net to have a look. Things started to come together as I looked at the solar data, solar flux is up and sunspots are as well ...that's good but look at the solar wind speed 689.5 also the K index is up around 4 which is not great but could be worse. the Bz has come up to +2.0. This morning when I checked the
Bz was way in the negative which is not good. The rise in solar wind and K index numbers pointed to a solar flare. The sun sure has been very busy on June 28th M2.4 class flare, June 29th M2.2 flare and now today two flares M1.0 and M1.6 class.
So in a nut shell things are very busy in space in such a way that radio is affected here on earth!! I have been using a less power as possible mind set here at VE3WDM to see how many miles per watt I can get. It seems I may have to chance the game up a little....see  how many contacts I can make compared to the size of solar storm that is affecting us.
 In closing let me know how this conditions are affecting you in your ham location. Oh and a side note to all those who live in the high latitude parts of the world.....enjoy the Auroras this evening.

See if you can identify this mystery interference….

Well over here at VE3WDM I have had a type of  mystery interference that shows up now and then check out the Youtube video below and see if you can identify it. Oh and as a sideline I have searched the internet for examples of interference and anomalies  such as AC line noise, Static crashes and birdies to name a few and have not been able to find anything!! Maybe someone could put up on Youtube examples of gremlins we hams may run across. Anyway post your ideas as to what this is..............

Seeing the big picture

The new setup
Old setup
 On Friday my new P3 SVGA card came in this cool add on allows me to move the band scope that is on the P3 up to a large monitor. This has been an add on I had been looking forward to for sometime. The SVGA card from Elecraft fits into the P3 and took about 20 minutes to complete the installation. It was then
New P3 SVGA

time to give it a whirl. As a side note I kept a monitor that I was not using but knew I would use it some day. Well the day came when I needed a monitor for the SVGA it's great when I can reuse! The P3 was hooked back into K3 I then powered up the K3 and P3.......BUT the monitor was blank!!! Well lets reboot and try again.....NOTHING..........It them came to me go to the Elecraft site and update the P3's software. I did that and low and behold the monitor came to life with a great looking band scope! It sure is nice to have a scope up close and personal. Now Elecraft has plans to add mouse control, RTTY and CW decoding and more suggestions are piling in. When I added the new monitor I had to do some moving of equipment on the desk. The LP-100A, MFJ 1026 and the LDG switches all found a new home. The monitor was mounted on
moveable arm so when not in use I can move it out of the way.  When the final position for all the equipment
P3 apart and ready for SVGA
 was found it was better than the old setup. All my ham equipment is on the same level and easier too view and adjust. Also it was due time to label all the cables and wires at the back of the ham gear. There has been many a time when I have removed cables to only have to re-connect them later that day and sure as shootin somehow I messed it up  with some very strange results. I pulled out the P-Touch label machine and tagged all the cables. It was a job that was long overdue and had to be done.  Now that I plan on making the Elecraft K2 portable I will be removing it from the desk along with all the hookup cables. Once I am done my portable op's the K2 can be hooked back into the desk position via the
SVGA installed

labeled cables. My next project is to investigate logging software, radio control software and propagation software. I have been using a hodge-podge  of software and I want to clean up the software end of my ham hobby so now it is time to look at some of the free ham software out there....any suggestions would be great!

ARRL DX CW contest done for 2012

Action on 20m
Since my setup does not allow me to be even close in the top running I try to come up with some goals before each contest,I find it makes the contest more interesting. Since this contest hosts a load of DX and the ARRL is offering a Diamond DXCC  challenge certificate for 2012 I decided to begin my DXCC country collection. During this contest I was not concerned with the number of contacts, concerned about spending to much time on making a certain contact or my hourly QSO rate. I was set on DXCC country hunting and working toward the 2012 DXCC award.

Contest highlights
  1. As always I operate the contest QRP at 5 watts but I also I was able at times to drop the power down to 5mW's. My longest miles per watts in this contest was 9339 miles per watt. 
  2. I was able to collect 65 DXCC countries during the contest.
  3. I made it into Japan and Hawaii with 5 watts I tried lower power setting but it was not working. 
  4. All bands (for me that's 10,15,20 and 40m) were open at one time or another and I had  contacts on all these bands. 
Contest downside
  1. This was the one and only downside I found for the whole contest.....at times when I came across rare DX and rightfully so there was a pileup. I found some stations would continue to send their call even over the DX station who was trying to answer a call. It's hard to find a hole to enter your call when (and they were very few) operators keep sending their call no matter what is going on in the pileup. 
To wrap it up the contest was great and propagation sure was not as good as in weeks gone by but still good. Operating QRP meant I had to send lots of repeats but the patience's of the DX op's was outstanding.  This contest gave me a good boost toward my DXCC award. 

Things are a changing……….

Lots of changes
As those of you know who have been reading my blog that I have no problem selling items that are no longer being used here at VE3WDM....and it would look like I am not done but that is a whole new subject. Since I have sold and bought items, things here at the shack have changed a lot. This afternoon I was looking at the pic on my blog of me sitting at the op desk and boy is it out dated!!! Some of the gear in that picture no long find it's home here but are being used at other op's. Just some of the items that no longer call it home are the LP-Pan (along with it the external sound card) that I built and was very hard to let go seeing it

The KAT100 and 100w amp enclosure
P3 and AKG headphones
was a project of mine. There was a second MFJ 1026 noise canceller which by the way went to soon in hind sight I would had sent it down to Larry W2LJ. I now know that he is looking for one due to Plasma TV troubles...would had sent it to him to try and buy. Then there was the K1ELUSB keyer that seemed to just be taking up space. Some the additions to the shack over the last little while are Elecraft P3 and all I can say is "it's excellent"!! I have remote mounted my Elecraft KAT100 tuner and 100 watt module in a separate enclosure. This allows me to run the K2 both at home and then grab and go for portable op's. Soon the battery and internal tuner will be installed in the K2 for the full portable operation experience. Another addition to the ham family was the CMOS-4 Logikit keyer by Idiom press. That seems to be about all the changes that have gone on here and I will be updating my profile picture soon to reflect the changes. I also sold the Heil Pro headphones since I am 100% CW then the Pro set plus was a waste. I read glowing reviews of the AKG K240 headphones I decided to go with those.

My YouTube debut……

The other day I received an email from the Elecraft reflector site mentioning Plasma TV's and the problems they can cause ham op's. I do have a Plasma TV and it sure does affect things here at VE3WDM so this thread interested me very much. As you know from reading my other posts I do have the MFJ 1026 noise cancelling unit and I have had good success with it. The post on the Elecraft reflector had a great link to a load of information on how the K3 and the MFJ 1026 can work together very well. Well since I have the K3 and the MFJ 1026 I investigated the link.  I found a very cool way to hook the both units together that
has some good advantages over the way I am now......or was using.

 With this configuration I am able to just push the RX ant button on the K3 and both units are inter connected. Also the way the MFJ 2026 is adjusted is a little different than I had previously adjusted the unit. I tried it and it is very easy, fast and works great!! So what are the advantages of hooking up your MFJ 1026 this way....well you never have to worry about the RF from your transmitting antenna getting into your receive antenna. With this hookup they are totally isolated. To include the MFJ 1026 it's as simple as powering up the MFJ unit and pushing the RX ant on the k3 and then some simple adjustment of the MFJ unit. Finally I decided to use my Iphone to video the results of the MFJ 1026 and the K3 and how they dealt with the Plasma TV noise. You will have to excuse the reflection of me in the Elecraft P3 and the audio may not be that great either but give it a go as it does show how the Plasma TV's interferance can be dealt with.

The Elecraft P3 has arrived……

The shipment arrived
Ready to go
The postal service came through for me and not only was the Elecraft P3 here before Christmas it made it to my home in a record 5 business days. The package arrived on Thursday but I had to wait for Saturday to open the boxes and drool!! Before the P3 arrived I had downloaded the manual and assembly instructions to go over things. I did have plans of participating in the ARRL 10 meter contest but the P3 blinded me to the contest.  The two boxes were very well packed with bubble wrap on all sides and the contents of each box again
surrounded in bubble wrap. I sat down Saturday afternoon as the morning was dedicated to putting up the Christmas tree and decorating our home. As always I took inventory of all the parts I encourage anyone who orders any kit to make sure you do the inventory. This kit is another of Elecraft's solder-less kits. It comes with the boards (front panel board with LCD, rear I/O board and rear RF panel  
Front panel done
board) all ready to go the only real assembly is the mechanical side of the P3.  By spending some time putting the kit together yourself you save some cash. The first step was to install some stand offs onto the front panel board these are used to secure the front LCD board to the front plate assembly. The fit of the front panel board into the front plate was perfect no binding or poor alignment of screws into stand off threads. I have found with all the Elecraft kits the attention to this type of detail makes the kits a joy to put together. It was then time to assemble parts of the enclosure and rear panel. The installation of the I/O board and RF board in the rear panel went very smooth. As the end was near it was time to install the 40 pin ribbon cable. The instructions for this were very detailed and clear. A red stripe on the ribbon cable was to be
I/O board installed

Back panel
oriented toward  certain parts on both the I\O board and the front panel board. Failing to plug the ribbon cable in correctly would result in damage  once power was applied. Lastly there was a TMP coaxial cable from the main board to the RF board and except for a few more chassis screws the P3 was done. The total time was about 2 hours with some breaks and taking my time. This unit is plug and play with the K3 radio. To get the P3 mated with the K3 there was a power cord that plugged into the K3. This way when the K3 was powered on so is the P3. ( there are other options for power up and only involved changing a plug in jumper on the P3) The IF feed comes from the K3 to the P3 with a supplied
The finished product
BNC coax jumper. Finally there is RS232 DE 9 cable (again supplied by Elecraft) between the P3 and K3 so they can "talk". I then brought my RS232 from the PC to the P3. This allows me to update the P3 over the internet and the P3 utility can communicate the P3. I have not had to much time to play with the P3 as Sunday was dedicated to shopping and resting as I worked all night Saturday.
