Lots going on….but no on air time.

No room for Oliver on the old desk
The new desk twice the size
The first half of August sure has been busy around the shack here, not busy with on air time but with getting things done. I have built the A A Engineering smart battery charger for my Elecraft K2. I will be posting the build in the near future. On this project for the first time the during the "smoke test" I actually had SMOKE!!! With kits I have found some of the final check out testing is what I call "destructive" testing as opposed to non destructive testing. Going to a destructive testing  with the Smart battery charger post. One of the kits I built just a short while ago was the QRPometer and it did not have a case...well it does now and that too is going to be another post. I am really not finished with that case yet. I was at the
electronics store the other day (picking up parts as a result of a destructive test going wrong) and saw a neat 9 volt battery holder I am going to add to the QRPometer case. I also have sold all of my items that were up for sale and I have the funds to order my Elecraft KX3. It's not going to be here until  October but that will give me time to read the manual and set up a place for the radio. While on that topic with some of my funds I went online to Ikea and purchased a much needed larger table for my kit building. The old desk was just way to small and things were falling off. The old table was actually a computer desk and it now is off to the side in my shack with an  iMac (27 inch screen) one that Julie donated to me!!! So the new Elecraft KX3 is going to run on Mac software.

F8DGY's antenna
The on air time has been very limited as having to get things done around the house and shack the rig really has not been turned on. I did manage to get some radio time in late last week in the evening. I heard clear as a bell Chris F8DGY calling CQ on 20m. I dropped the K3's power down to 500mW's and gave him a go. He came right back to me with a 579 report. It was a fast exchange and he was off answering others. For me that that a 7,597 miles per watt contact.

Soon there will be a new KX3 coming to town…

Elecraft KX3
But
To help raise the funds for the new Elecraft KX3 some items here at the shack have to go up for sale....including my beloved KX1!! I have a new page with all the "for sale" items on it have a look and see if anything there can find a home in your shack. Yes Yes there was a post on my blog regarding my Elecraft K2 and how it was just fine (and it still is) and I did not need a KX3........BUT the bug has bitten.........and it has gone from a need to a want!!!

Other goings on at VE3WDM
When I ordered my Elecraft K3 some years ago I had it outfitted with the 100 watt module....as most you know I am not a QRO op....not that there is any at all wrong with QRO but for me QRP and QRPp is the best option considering my stealth operation. So the 100 watt module (KPA3) was put up for sale and sold in 1 day to help fund my KX3. Now my Elecraft radio is what is called a K3/10 (10 for 10 watts max output). Removing the KPA3 meant taking out my Sub receiver from the rig, the NB board along with some jumper cables. When events like this come I just hate opening up a 5K rig and playing around with the "stuff" inside. All went well and  it's back together and working just fine. 
I tried and I tried and tried to contact CY9M but it just did not work out that DXpedition is not shut down and it just was not meant to be. This weekend is the NAQP CW contest it starts at 2pm local time and runs til late evening. I am going to give this popular contest a go considering the not so good propagation lately this local contest will be fun even with max 5 watts. 

What else in new
I have an Elecraft K2 with the internal battery pack and up to this point I really have not been charging the internal battery to optimize its life. Some time ago I came across A&A Engineering   They offer a great charger for the Elecraft K2 internal battery. I ordered it and it arrived in no time it's waiting to be assembled because....surprise surprise.... I ordered the kit!!


As for my kit from DIY electronic kits the USB 0-500mhz USB power meter kit has been soldered  and is all together BUT is seems it has to be calibrated as the output of the rig is not even close to the readings I am getting with the kit. I have emailed the DIY electronics company over and over again but nothing.......seems that was 90.00 down the drain. I am going to keep it up and if I can I want to  find a phone number I will then call them and demanding a refund!!! On an up beat note I posted a short time ago about a kit that I ordered and put together call the QRPometer. This kit is a great QRP watt meter and SWR meter but it only goes done to 500mW's..........now for most of you that is just fine but not here at VE3WDM!!! I like to operate now and then at QRPp levels. This means I need a meter that will give me good and reliable wattage readings from about 10mWs up to 100mWs. This was the reason for me ordering the USB 0-500mhz USB power meter it brags of getting down to the low mW levels..........IF YOU CAN GET IT TO WORK AND GET THE DAM TECH SUPPORT TO EMAIL YOU.........take a deep breath......ahhhmmmm.........ok Im back. Talking with the 4 state qrp group (those who produce the QRPometer) I am told the meter can have it's decimal place changed!!! This would give me the QRPp readings I need. This is a project that is now in the works and I will keep the blog readers posted as to it's progress. 
In conclusion I always like to preview my blog post before it has goes "live" and for some reason the post is DOUBLED SPACED I have looked into this but am unable to find the answer..........keep you all posted on this one!!

Hendricks 41dB attenuator built and added to the mix

Hendricks attenuator in service
It's Friday and the IARU contest is tomorrow, I had been checking out the propagation throughout the week and things seem to be calming down. Well until yesterday afternoon and the sun released an X1.4 solar flare and if that was not enough a CME as well..... Oh did I mention the CME is headed in our direction as well. So far the solar-terrestrial data seems to be ok. What's not to bad about a proportional hiccup is that it affects all of us, not saying that is a good thing but in the contest  the playing field stays level. This past week my Hendricks 41dB attenuator came in. The assembly was straight forward and was done in no time it
Final testing
tested out ok and I was ready to start using it. The attenuator has to go in series with my antenna  I placed it in series with my antenna B port on the K3. Both feeds from the K3 (antenna A port and B port) go to a LDG DTS-4 switch. Here I am able to place the dipole antenna in series with either antenna Port A or B. I did this as I can set up the K3 to have different settings (power output, filter selections, ATU on or off... etc) for each antenna port. So I select either antenna A or B on the K3 and then on the DTS-4 I select either attenuator in or out.

Now when I want to use the attenuator it's a matter of selecting antenna B on the K3 and Ant B selected on the DTS-4 and I am ready to go with all the setting on the K3 done.
My goals for the IARU conest
  1. Have fun and enjoy!!
  2. Look for DXCC's I do not have so I can add to my  ARRL Diamond  count.
  3. See if I can beat my miles per watt record of 45,868 miles.
  4. Have fun and enjoy!!
Some of the extra parts
Back to the Hendricks attenuator for a moment..........the kit did come with some extra resistors and switch also the hookup wire was missing.  I also noticed that the color code for one of the resistors had a misprint in the manual. I emailed all this information to Hendricks last week and up to this point I have heard nothing. Also I did have what I thought to be a problem I emailed Hendricks about it. Their reply was "I don't know" and that was it!! Well I figured out the problem on my own but this being my first kit from Hendricks I was not impressed. Maybe this is just a one off many of you out there have had kits from this company what has been your experience?




It’s time for surgery………..

Ready for action
The time has come for me to open up my Elecraft K3 and preform some surgery. When I purchased the Elecraft P3 to enhance my K3 all was fine until the P3SVGA board was added to the P3. Since the power source for the P3 comes from the K3 with the addition of the P3SVGA board to much power was being  drawn. A
Diode to be removed
resettable fuse in the K3 now and then would trip out. So Elecraft (as they always do) came up with a mod for this problem.  The mod was sent out free BUT it meant opening up my 4k plus radio and removing one SMT diode, inductor and resettable fuse and replacing them with beefed up components. I didn't mind opening up the K3 and adding plug-in components....whole different story when it comes to De-soldering and soldering on the boards!!! For that reason the mod kit sat on my self for about 2 months, after all the P3 was now plugged into it's own power source so the problem was more or less solved.  This weekend in Canada is a long weekend (Canada day) and as always I get bored when I have to much time on my hands.......a little bird whispered in my ear that the board-um can be solved by doing the long over due K3 mod!!!  The board-um got the best of me along with that dam bird!!  I removed the K3 from service and I will say there sure is lots
Fans removed
KPA3 removed
of cables that go into the rig!! With the rig on the bench and beads of sweat starting to form I was off to the races and I hope with a celebration when I hit the finish line!!  As many times in the past I took the covers off and dove in. The first step was to remove the SMT diode easer said then done. This thing is very small it came out with
very little trouble. Installing the new one was another story and it did take me several attempts. When all was said and
 Old F2 and RFC 48
done it was  not a pretty site at all but it's in and I hope it works. I was so nervous about screwing the SMT install up that it caused me to hesitate and be over cautious. So that resulted in the SMT not looking professional at all BUT I have fallen into this trap in the past, trying to make it look good and in the end totally screwing the install and or component up. I told myself "it may not look great but if it works thats what counts in the end" The other two component replacement required me to remove the KPA3 cooling fans and the KPA3 unit. The
Ready for new parts

instructions did say the KPA3 unit did not have to be removed if you were very very careful it could be done. Not feeling at all brave out came the KPA3 unit as well. The inductor and resettable fuse that had to be replaced were in plan view and HUGE compared to the SMT diode. I now had to DE-solder the two components and this is were the Hakko 808 was stellar. In under 30 seconds both component were
Great tool to have
out and not a drop of solder was left on each pad. The Hakko 808 is well worth the money that was spent on it, for removing components it's the cats behind!! Soldering in the new components was a breeze and it was time to put the rig back together and do the smoke test.
back home and working

New parts installed

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!

It’s been one of those weeks………..

Well it's now Sunday and I just don''t know where the week has gone it does not even seem like the weekend has begun but it's almost over! It has just been "one of those weeks" I have not been able to get any radio time in....for that matter really not to much of anything has been done this week. It has been a busy week but as I look back can't really say anything was started or completed. As I have reported in my blog I am
This is the powerport box without the battery
making my Elecraft K2 portable so I can use it in the car and the out of doors when the warmer weather comes. I ordered a case from the Powerport store the case I ordered was the Radio box. It's been 4 weeks now and no case has arrived I tried to email them regarding this as I was emailed when the case was shipped. I then read on their site that they do not respond to emails just (long distance) phone inquires.  I wanted to wait until Friday just to see if it came in....but nothing. I then ordered some very nice Sony head phones for my portable op's from Ebay....and again 5 weeks have past and nothing. I did email them and was told they were shipped but they will ship another pair on Monday......It's just been one of those weeks!

Idiom Press CMOS-4 Keyer………

Sorting the parts
Good afternoon all, just the other week I finished building my Idiom press CMOS-4 keyer. When I was investigating the keyers from Idiom press there was another keyer called the K5 which had 6 programmable memories. The K5 did not seem to come as a kit and it was more pricey as well so I settled for the CMOS-4 kit. I ordered it online with my credit card but unlike other kits I have ordered from other companies this time around I was never sent confirmation of shipment or a tracking number....nothing......it just arrived here at the
house one day. Anyway, I had read many great reviews about this keyer and has seen some YouTube demonstrations of it was well so I was eager  to get it built and running. If you have read in
RCA troubles



my blog in the past the first thing I like to do with any kit I get is do the inventory of parts. It lets me know all is here as well familiarizes me with the parts. This kit like all the others had part numbers for the parts but for some reason the list gave you a part number and told you it was a 15 ohm resistor for instance and that there were 20 of them and  that was it!! So these 15 resistors were they R1, R20, R3 or what, as the kit had other resistors with other part numbers and values assigned to them. So for all the parts I had to go through the build
Resistor and diode layout

instructions and identify that transistor part number ZC4005 which was a MPSA92 transistor was in fact Q1 in the assembly instructions. Each part had to have this done and I then put the parts in a bag and labeled the bag with the assembly part number on it. The assembly instructions were very clear but more pictures would be very helpful during the build. Steps that involved an odd detail were marked out very clearly and at times in BOLD print. One part issue during the build was an RCA jack that would not fit through the per-drilled hole. This is not a disaster but a bit of a pain having to get the cordless drill out to open up the hole. The only other issue I ran into and should be rectified in my humble opinion is.....there are some diodes that have to be installed and there is a polarity to follow. To make this easier the
Diode circles missing at bottom

silk screen on the PC board has a large circle place over one of the diode holes. This is to help with placing the diode on the PC board with the right polarity. Well for some reason there are 3 areas D2,D3 and D4 were the circle did not make it onto the PC board. You are told of this in the instructions and shown on a layout diagram with the proper polarity. How about fixing the boards as well.........Those were the only issues I had with the build. The kit tested great once it was done and if you do order the CMOS-4 as a kit or already built make sure you read the operating manual cover to cover. This is were the kit really shines great detail has been put into the manual. Because this keyer is a real stand alone keyer all programing is done with your key no computer is needed. In the manual you are given exercises to do and make sure you do them!!! This will get you accustomed how the keyer works and how to program it as well. If you are in the market for a keyer this is one to take a close look at. In this post I wanted to include some assembly pictures as I found on the internet there were very few. As you are going through the build a picture would really help at times.
