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.

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?

Dayton with many more surprises

My issue of QST came in yesterday and the back page made the new Kenwood rig official !!  There is a great pic there of the new TS 990S but with little to no spec's. The available spec's brag of a top RF output of 200 watts, HF and 50mhz, built in antenna tuner,built in power supply and really thats about all the info Kenwood released in the full page release. Viewing the picture one can see two USB ports which are nicely placed on the front of the rig. A very impressive color TTF display along with a band scope, not if the rig houses two independent receivers but it would seem so as there are independent controls for each receiver on the right hand side of the radio. Not sure as of yet what the optional components of the TS 990S are.  So what are your impressions of the new kid on the block??

My DXLab's desktop

Over the past couple of weeks I have been dabbling with "all in one" radio software. I narrowed my search down to Ham radio deluxe and DXLab. In the past I had about 4 different radio software programs on my computer. I found that I used one for a month then switch to another one. I would once again have to hit the  learning curve to get familiar with the program. A lot of time was wasted doing this and it could get very frustrating at times. So last month the decision was made to narrow my choice down to ONE and stick with it. So it was time to release the hounds and begin the chase!!!! It was recommended I give DXLab a shot. Up to that point I really had not heard of this program not sure why but just never had. After working with this program over the past month I have decided this is the program for me. DXLab's is made up of 8 applications ranging from rig control, logging and a  web cluster app just to mention 3 of the 8 modules.

1. You can pick and choose what applications you want to install. 
2. Once an application is installed you are able to customize it to your needs.
3. Great support, the short time I was running DXlabs they released fixes and upgrades.
4. Running all 8 applications  did not seem to take up much of the PC's processor.
5. Each Application has over the top documentation in great detail. 
6. It will start up 3rd party applications to run with DXLab. For me so far I have my LP-100A virtual meter starting up within DXLab. 

1. Make sure you read the documentation to fully understand what each app can do. 
2.  The first application you want to download is called Launcher. This app when up and running at the push of a button install each app you want to try. It also (when configured to) will check for updates of all the programs each time it opens. It will also with one click start-up and shut down all DXLab app's. I made the mistake of not using this program and I manually unzipped, created a folder and installed each application. The Launcher makes installation a painless experience. 
3. Join the DXLab yahoo group for outstanding support. I posted a questions and it was answered in 20 minutes.  

So in conclusion this is one of the best programs I have come across and it's FREE as well. I have not as of yet installed all the application programs that I have planned too. I want to take the time to read about each app and understand it's capabilities. So for me it's still a growing adventure if your in the market for an all in one radio application do give DXLab's a shot!

QRPometer complete

Well the QRPometer has made it from a pile of parts to a very useful tool for the shack and portable op's. It's no wonder this kit sold out in record time and now the 4 state QRP group will have to round up more parts and move out some more kits as the demand is out there. I began this project the same way I have with all my projects.... by doing a parts inventory. That went by without a hitch all the parts and pieces were present and accounted for. It was then off to the "puttin" the parts where they belong. The instructions are very easy to

Solder blob mod done

follow and very well laid out. If you are not sure about things and need a picture you will find it on the 4 State QRP groups website. During the resistor install there is a note to hold off on two resistors until after the calibration stage. I did get an email from the 4 State group letting me know that there is also a third resistor that should not be installed as well. Now that is great support each person that ordered a kit receive an email with updated info! There is a very small mod that has

Ribbon cable soldered to LCD

 to be done to the LED meter a solder blob has to be removed from a pair of pads. A new blob has to short a pair of center pads it went very smooth and allowed me to use my Hakko 808 to remove the solder blob. With all the parts installed it was now time for calibration and I wish all kits could be this easy to calibrate!!! All that is needed is a voltmeter (my Fluke meter) for the first step and then an RF input between .5W to 5 watts (my trusty K3) for this second step.


The kit pro's
1. Very easy to build and calibrate
2. No toroid or SMD for those kit builders who shy away from them.
3. Instructions are well written and very easy to understand.
4. Meter has a built in dummy load when measuring power.
5. When meter is turned off it can still be left in series with antenna and transmitter the meter is in bypass.
6. Professional silk screen front panel.
7. Parts layout on the the circuit board are...may I say "Elecraft quality"!

Con's

Calibration complete

1. The TX and ANT connectors are RCA and not BNC. I had to buy RCA to BNC adapters.
2. There is no cover for the back of the circuit board.

So lets put 2 and 2 together.......7 pro's to 2 con's = home run!!

The 4 state QRP QRPometer

Back in late March I read on W2LJ's blog a post about the new QRPometer available from the 4 state QRP group. At the time I was also building my Elecraft KAT2 antenna tuner. I was getting to the stage of testing and setting up the tuner. I needed a watt meter for one of the tests. I do have the LP-100A meter and it is a super meter! BUT for me to use this meter it involves removing it from my Elecraft K3 setup and that is a REAL pain to do. So reading Larry's post about this new meter had me come to the understanding that this unit would be a nice fit for my shack......and also it's a kit! This little unit is a great SWR and watt meter. It's reads from 10 watts and goes down to 100mW's it has a large easy to read LED read out. The kit arrived at the shack on Wednesday of this week and it's still waiting assembly. I was fortunate to get the kit as it sold out very fast. I hope to get the unit built over the Easter weekend.

I really enjoy kit building I find it to be a nice pass time when the propagation is not co-operative and the bands are slow. With kit building it's a learning curve starting out with basic kits and moving up to kits that
contain SMT components....I have yet to dive into that pond. There sure is a reward when you have spent time

Replacing a cable

assembling a kit and then to see it work is  a great feeling.
Recently I had to open up my Elecraft K2 to add an internal antenna tuner and battery. I had not had the top off the K2 for some time.....I was amazed at all the components to which I thought..."I actually put all this together" For those of you who build kits like me you have run into times when things just don't go as planned. I have soldered components in the wrong  place. There has been solder run onto two pads instead of the one the solder was intended for and so on. I would bet there are a lot of kit builders out there who have their own stories.  As kit builders we all have our "tools" from soldering stations to multimeter's

Hakko at work

and everything in-between. One tool I purchased about a year ago and really don't use all that often but when used it sure has gotten me out of many binds. The "magic tool" as I call it is the Hakko 808 desoldering tool. In the past I have used the hand pump, hand bulb and soldering iron and bulb combo. These did an ok job but at times all had failed me. The Hakko 808 is very efficient at removing soldering mistakes and at the same time saving the component if placed in the wrong location. The Hakko heats up very fast, the vacuum pump is powerful, maintenance is minimal lastly its very user friendly for filter changes. I know that solder mistakes only happen now and then but it's sure great having the right tool for the job at hand.
