Now that fall is in full swing and most.....typo alert remove  "and most" (thanks to Gary at rework eliminator for Elecraft K2)and soon all the leaves will have dropped from the trees. The temps  already are starting to drop not yet to freezing but soon. So outdoor activities will be more limited as winter gets her firm grip on this QTH. 

Serial 7372 soon in the works

I find that radio conditions do improve in the winter months and there are some major CW contest to keep me busy on some of the weekends....but.....I don't know about my readers but I also like to have a few winter radio projects on the go. This winter's project is an ambitious one that satisfies my kit building hunger. I purchased another Eelecraft K2 kit, my first K2 kit was a blast to build. With this kit I want to take my time and very much enjoy the build. Another decision I made was to sell the rig once built and run through it's paces. I then can use those funds to put toward my next winters project. I try to keep what I call my well rounded approach to ham radio. This includes on air operating time for sure, reading my monthly ham radio

K6XX's kit for the K2

magazines, blogging and blog reading, interfacing computers with the hobby and of coarse kit building. I also wanted to add a CW tuning aid to my original Elecraft K2 and it just so happens that K6XX has a kit to add a CW tuning  indicator to the rig.  This kit has the dreaded SMD parts!!!! Now having said that I used to say that about kits that came with winding toroid's and that is not a big deal anymore. Below is a video of how the tuning light works.

Charger ready for testing

I have built  A&A Engineering's 1 amp Smart Battery QRP charger mainly for my Elecraft K2's internal battery. This very much is a smart charger and here are a FEW reasons why.....

1. The charger can be connected to the battery indefinitely and no harm will come to the battery. Once the battery is fully charged the Smart charger will remain in maintenance mode delivering a float charge. Therefore the battery cannot be over charged.

2. The charger can stay hooked up to the battery while operating the radio if you so choose to do so. The charger will enter the bulk mode to help with the load of the radio operating.

3. When the charger is connected it automatically determines the type of charge the battery needs.

Close to done but no heat shrink on LED

 The charger can either be ordered fully assembled and tested or as a kit.....yours truly held true and strong the the QRP spirit and chose the kit. The kit did arrive very fast and all parts were checked and accounted for. If you are a first time builder of  kits this may not be the one for you as the instructions are vague at times. I did get myself into problems after  realizing I had missed part of the assembly and had to go back to add parts and two jumpers. The kit does not give you the "standard" step by step instructions regarding assembly. It's more or less tells you too "install the components according the the pictorial diagram".  There are even little side notes here and there one in particular relating to jumper installation that I totally missed. I did get the charger all together and it was time to check the unit out. So I plugged the charger in, turned it on and ........no 12 volts DC from the leads on the charger!!!!

Fried resistor

 It was time to check the board to see if parts were installed according to plans and if all solder joints were good and soldered. All seemed to be good so it was off to the internet to see if anyone had the same troubles. It was on the internet I found a test procedure for the kit version of the  charger from A&A Engineering. For some reason beyond me I am not sure why this was not included in the kit!!! Anyway.....one of the things what was emphasized was if the charger is not hooked up to a load you will NOT get any output. Well that solved the problem of no output and things now seemed to be "normal" There was a test procedure in the text that

Decided to use Anderson conn's

allowed you to see if parts of the charger were working as they should. It involved removing the IC and shorting legs of the IC 16 pin socket to certain areas of the circuit board. When this was done certain voltage reading should be observed or LED's should turn on. Here is my BIG problem with this type of testing......when you short things out things can go WRONG and they DID!!! I guess I was not paying close attention and I shorted the wrong pin on the IC to ground and I FRIED a resistor on the board. When you short out to test I call this a destructive way of testing I much more prefer using a meter to look for certain voltages. If  you either don't get the right voltage or a down right outrageous voltage you understand
either:
1. You are in measuring in the wrong place.
2. You have made a mistake in the assembly.
In either case nothing has been toasted

Some heat shrink fun

In the end all checked out ok with the Smart charger and it working great to charge my Elecraft K2.  Over all this is a great unit even with the hiccups that I had. Some of the things that are not clear in the instructions are as follows
1. The heat shrink tubing is very clearly stated to go on the transistor but it also should go on the leads of the LED's...that was not so clear and I have redo the LED's.
2. Make sure you add the jumper J1 to J2 in my case it is mentioned but off to the side of the instructions
3. There is no diode to be installed in D3 position, instructions just say install parts and there are is D1, D2 and D3. Just install the diodes (both are the same diode) one in D1 the other D2.

D1 needs to have the diode not D3

4. If  you ordered the QRP version of the charger as I did you will get a separate kit that allows the charger to switch between two charging currents. Read those instructions and install the resistors they tell you too or you will end up removing resistors if you follow the main instructions then move to the add on kit instructions as I did.
5. When done remember the output leads will SHOW NO VOLTAGE UNLESS A LOAD IS APPLIED.
6. The document required to test the unit can be found at the link above under "test procedure". BUT when  you do it be very careful!!!

The setup at the park

Last weekend on Saturday the weather here was great lots of sunshine and very few clouds. So it was off the the park with the radio to give the ARCI welcome to QRP contest a go. Its a 3 hour contest from late morning to early afternoon. I setup my Elecraft K2 along with my mono band mobile whip antennas. The key I used was the Mini Palm paddle which works great and has a super feel to it. I found the bands to be in good shape but was not able to find many who were participating in the contest. In total I made 3 contacts contacts in 2.5 hours of operation. While operating I did hear W6/DL6AP/P who was operating in the SOTA at location CT-086....translation Strawberry peak in California. I was not able to contact W6/DL6AP/P but I did hear him in there. There was some other very attended State QSO party contests going on at the same time and were very well attended. So over all I did not strike it rich in the contest by any means...BUT.......I did pickup some bonus points for just being portable on battery power with a portable antenna.

Packing up for the contest

I took part in the first annual Skeeter contest sponsored by the NJQRP club the first years theme was to go to  your favorate outdoor operating place and get involved with the contest. Well up this way the weather was not looking like it was going to co-operate. My fav place to operate was out in the open and very vulnerable to the weather....namely rain!! I decided to head out to a location that offered some trees as

The weather to look forward too

shelter just in case of a sprinkle, as for a down pour my car was beside me and the rest of the contest could be finished from there. I was using my Elecract K2 and this by the way this was the first contest  this rig has ever done as battery powered. My key was the Mini Palm Paddle which by the way worked great!! My antennas were mono band mobile whips on the back of my car. I operated QRP at 5 watts Oh and the K2's battery lasted for 4.5 hours at 5
watts with me calling CQ and not searching and pouncing.
The weather was a mixed bag from nice sunny skies (very rare) to very threatening overcast that did let go

The setup...with a bit of rare sunshine

with rain at times.Over the last month the temperatures have been in the upper 30's and low 40C...today it was nice and cool almost to the point of putting on a long sleeve shirt (which was used to cover the rig during light rain). The location I chose was about 15 minutes from my home and offered a pic-nick table, trees and what I consider a luxury when operating out and about a portable washroom!! The bands were busy with not only the Skeeter contest but the WAE contest as well. I did have some European stations involved in the WAE contest respond to my "CQ Buzz contest" Thats ok they gave me their report and serial and  I asked for their power output and then they moved on this made it a skeeter contact....I believe anyway???

Covering for rain drizzle

I confined my operating to 20m as it seemed to be a "buzz" with skeeters but at 14.060 for some time there was some SSB going on, not sure if anyone else heard it but they were there right on the CW QRP calling frequency. While calling CQ I did have someone come back to me at the same time a passer by asked me what I was doing and showed an interest in ham radio. So I sacrificed the contact for taking time to talk with this gentleman about the hobby. So if your reading this blog I was not ignoring you just had to promote the hobby.....:). I had to end the contest around 4:40 as the Elecract K2 was telling me that the battery is getting to the point of no return so it was time to shut things down.

When it really rained

I made in total 19 contacts including DJ5AV from Germany and YU2A from Serbia. 12 of  the contacts were fellow Skeeters as they had Skeeter numbers. One contact was just an average QRP op not in the contest but wanted to know what he had to give me as an exchange so he could count in the log. Over all I had a great time even though the weather was touch and go at times.

Finally...a must have!!!

See all you Skeeters next year!!!

Portable op's QTH

VE3WDM portable in action

It was and still is a beautiful day here at VE3WDM there is a nice cool breeze, the sun is shining with a great temp of 17C. I have been itching to get the K2 operating mobile as I have been working most of the winter getting the K2, antenna and mount ready to go. I spent the morning and early afternoon spring cleaning the shack and found some
stuff I really don't use anymore thus it will be sold for  "ham bucks". Cleaning up the shack gave me the warm fuzzes once is was all done and long over due for sure. I just hate looking for

all packed away in trunk

something knowing I have it but not really sure where it is!! Julie was involved with her photography getting some details together for some up coming weddings she is photographing. It was the perfect time for me to jump in the mobile and give the K2 setup a test run. Before I hit the open road I always like to go online to WA7BNM contest site and find out what contests are on for the weekend. It's a great way to make contacts if the QRP fishing holes are fish-less. There were some local QSO parties and the ARI international CW contest. I found a nice quiet place to operate which is real close to home. Setup was a snap but Murphy did play games with me. I had forgotten my binder at home which contained my paper pencil as well as a cheat sheet for the K2 just in case I forget how to do something. I was able to find some scrap paper and pen in my carry bag....so it was off to the races. I set the K2 for 5 watts all my operating would be 20m's as I only have mobile whips for 20m and 40m's at this time (something the ham bucks may help me with) I operated for about 35 minutes in total as dinner had still had to be shopped for and it was BBQ night!!

1.  NN7ZZ                Mendon UT                14.047
2. K7EAR                Solomon AZ               14.040

4. IZ1A                    Italy ARI contest         14.022       QRZ.COM can't find maybe incorrect copying 
5. DL5AXX             Germany ARI contest  14.010       810 miles per watt. 
6. IK2HDF              Italy ARI contest          14.011       834 miles per watt.                                                 I was very happy with the how the antenna and rig worked and was surprised at the distance I was able to get. I know for sure next time I am going to lower the output and start making some 1,000 miles per watt potable contacts. Some things that have to be worked on before next time......remember all the items to bring, some bottled water, longer cable for Palm paddle key and some adjustments to the Palm paddle key are needed. Well it's time to spark up the BBQ and get some dinner...cheers!!!

The new "ham mobile"

Removing some metal from the K400

Well the summer is fast approaching and with it the warm weather. over the winter I started to get things ready for some summer portable op's from my car. It involved getting the Elecraft K2 mobile ready and
setting up an antenna system that was easy to deploy and worked well. Now there was a small hitch in the plans that happened about 2 weeks ago Julie and I decided to downsize our

New and improved mount

cars!! We both had large 4 door Chev Malibu's and loved them.....but so did the gas pumps! We both upgraded to the Scion IQ's half the gas and half the size. Now this meant plans had changed for my summer mobile portable operations....well not really. The Scion is a hatchback and I would just have to use my trunk mount Diamond K400 as a hatchback mount. There was just one small mod that had to be done to the mount to allow it to work on the Scion. That involved removing a small part of the flange that stopped the hatch from closing as it rubbed on the bumper. With that done the K400 fit perfectly on the Scion's hatchback. I was still going to use my faithful and reliable Palomar mono band mobile whips. With the Scion being a  much smaller car I was not sure what the reduced ground plain was going to do to the SWR?? I was prepping for the worst thinking that the SWR was going to be high no matter how I adjusted the stinger on the whip but the K2 antenna tuner would fix that. Well to my pleasure the 20m whip at 14.060 is 1.5 and the 40m whip at 7.030 is 1.4. This was with some adjusting of the length of the stinger but very pleasing

results. The two (for starters) mobile Palomar whips did not really fit into the old lawn chair bag as I had planned so I am going to have to come up with another plan for a carry sack for them. I am going to be stationary mobile....not sure I want to bang out CW whilst driving among the trucks and traffic on the highway!!
