My brother, Wil, who is also ham radio operator AI4QT sent over a couple of Gamma Research Power Supplies for me to experiment with and use.  This power supply is amazing considering its small size.  In fact, the footprint is less than a QSL card yet has enough power to run a 100-watt transceiver.  Click on the link to the video for a review and see how it was adapted to use Powerpoles for DC output.  I plan to use this little guy for a month or so of portable use then give a review on its field performance.

I often get questions about how my CW progress is coming along and do I have any tips for learning CW so I decided to capture my thoughts in a video.

As for my progress, I’m virtually 100% CW and enjoy QSOs in the 15-18 wpm range…comfortable for either a straight key or using my paddle.

I contribute my progress to two things. One my desire to learn CW and the other to CW Academy.  This video covers the concepts taught in class, what to expect, how to prepare and tips for getting the most out of the class.

If you are considering learning CW or improving your skill/copy I highly recommend CW Academy. Check out the video for the complete story.

In a previous blog post I mentioned I was building a 9:1 unun for a long-wire antenna.  I just complete the project and the results were a little less than I had hoped for. The SWR was a little high on several bands…in the 2.5-3.2 range.  That’s a little too high for me to feel comfortable when using my QRP rigs.

The video will be out later this week with the test results shown. I want to solicit comments from other builders out there who may have suggestions on how to get better results.

Stay tuned.

From time-to-time subscribers to my YouTube channels send along items that may be of interest to me or to my viewers. The past two weeks have been bountiful to say the least.

In fact, I can see a :how-to” video using Buck Converters on the near horizon.

Thanks to Preston, Joe and George for sending along the much appreciated gifts.

MFJ 259C_resize

Happy days are here again.  My MFJ 259C just returned from its round trip back to Starkville, MS for repair. The entire repair process took just 14 business days.  Not bad, especially considering one of those weeks was Dayton prep where MFJ travels the crew to Hamvention.

I know MFJ gets lots of grief over its “Quality Control” and in my opinion much of that is undeserved.

I’ve got several pieces of MFJ gear and yes, I’ve had to go back and make a solder repair on a QRP Wattmeter after years of bouncing around for portable use.  Is that a fault of MJF?  Or was it my use and even abuse of the item? Either way, three minutes with the soldering iron and I was back in business.

If we could only have a perfect world my lawnmower (made with LOTS of plastic) would not suddenly quit running when one of those plastic gadgets gets loose. Or my Jeep heater core would not leak. Or my microwave door would not have broken even though it was just out of warranty. Or…well you get the picture.  Even things costing many hundreds or thousands of dollars more have problems, defects and aggravations.

So perhaps MFJ is not that bad, considering the myriad of items they provide to the ham community and the jobs they provide to Americans.

Oh, the meter works flawlessly once again…be watching for more QRP antenna videos.

Hope to meet you on the air soon.

As I get older and the eyes get a little weaker, I sometimes have trouble counting turns or windings on a toroid, especially the smaller ones.

Here is a quick tip that may help make the job easier just by using your Smartphone or tablet.

I recently attended the Four State QRP Convention (OzarkCon) in Branson, MO.  While this was my first trip it surely won’t be my last. The event was great and meeting fellow QRP operators even more so!

One thing I’ll do differently next year is bring along an antenna suitable for operating from a hotel room.  I suspect a long wire with the ZM-2 tuner will do just fine; all I need is a UnUn to make it work so I’m getting the parts together for the next video.

The UnUn is very easy to make requiring little skill, money and time.  A perfect combination if you ask me.

Here is a picture of the workbench as I’m getting ready to build.  Watch for the complete YouTube video coming out in a couple of weeks.
