About K3NG

If you are looking for support for any of the projects on this site, please consult this page.

If you hear me calling CQ MY TEST, I’m operating My Contest. The exchange is RST.  It’s your contest as well and you’re welcome to participate in it.

I QSL via LOTW usually within a day or two and prefer this over paper QSLs.  I no longer have an eQSL account.  If you’re not on LOTW, you should be.  It saves paper and it’s fast.  It takes a little bit of work to get it set up, but you’ll be glad you did.

My postal address for paper snail mail QSLs is

Anthony Good

5145 Pohopoco Drive

Lehighton, PA 18235 USA

I QSL 100% with an SASE, however I’m often very slow at paper QSLing. I tend to amass cards for a period of time and then respond to them all at once. Don’t be upset if you send me a PSE QSL card and you don’t hear back from me right away. I *will* QSL sooner or later. If I’m the very last QSL you need for 5 Band WAS or County Hunters, email me and I’ll try to expedite it :-)

The K3NG home QTH shack is powered with a 100w solar panel and two deep cycle batteries.  You can enjoy our QSO knowing the electrons from my rig arriving at your antenna are carbon neutral.

I enjoy QRP, 6 meters, CW, DXing, making microcontrollers do cool things, and hiking with Amateur Radio.  I’m getting into DXpeditioning and you’re going to see me on a big tent-and-generator expedition below 40 degrees south latitude someday.  Turn-offs include political discussions, phone operation on 80m, and old people who act like really old people.  I will not join FISTS due to the North American chapter leadership’s position on the elimination of the code test and public statements made regarding CW that in my opinion are detrimental to getting new people into CW and amateur radio.

I do not publish my information on QRZ.com these days as it has become a podium for egomaniacs, political wingnuts, and antagonistic moderators.  You might want to try using these fine sites for callsign lookups:

  1. Hi Goody,
    Tnx for attempting a QSO with me on 7040 today. You were clearly copyable to begin with but then got stomped on by other stations and some noise. I did manage to get your name and signal report, though. You were my first QSO with the Tuna-Tin-Two/Sudden Storm combo – putting out about 500 mW to a Cushcraft R8 vertical. Tnx for hanging in there with me. If you think we managed to exchange enough info on the air for a valid contact, I’d like to exchange QSLs to mark my first flea-power QSO.

    Tnx & 72/73 for a happy new year,

  2. i noticed you had trouble at one point logging into VHFDX,Info. I am having the same run in circles experience, did you ever solve it?

    • Every time I’ve had an issue it’s been a server side issue. I see errors that point to database issues or resource exhaustion on the server. I’m guessing the site is too popular and it tends to get overloaded. It is a great site and I miss it when it’s down.

  3. Great site Anthony. We’re running parallel on many aspects. Have just started the keyer project which will be a great learning curve for me.

  4. Hi Anthony its been a long time since i fired up the code you have for the yeasu rotor ,i have been busy myself with a icom civ band decoder based on (antenna matrix – ON7EQ ) with lots of help from – Pete VE5VA ,any intentions of maybe adding that to antenna tuner unit you have as its running on a mega 2560 now but might have to redesign the switching for in band and out of band antennas completely ….

    Regards

    • Icom support is on the list. I was looking through the code and I think I can follow it as an example. I hadn’t considered automatic switching of antennas based on band, but that’s a great idea I will throw on the list.

  5. Hi Anthony
    Pete and i have made good improvements with the original code … to many to name ,but what we are currently sorting out a big stumbling block and has been a terrible bug to resolve and i think we going to have to re-engineer the code as im sure if you look at the code you will notice that
    the way in which it works is freq gets mapped to a band then antenna but the correct way as Pete has explained to me is by mapping the freq to a antenna and then to a band to be able to get the correct default antennas assigned ..Hope that helps ..I am also willing to do some basic testing of the code if you like and pick up glitches on the antenna selection on a full time basis… As that gives me a chance to learn more as well :-)

    Thanks for a very informative and diverse blog.

    I’ve developed a fairly novel approach to home-brewing a beefy antenna rotator, using a readily available Buehler gear motor and 60:1 gear reducer plus chain drive gearing. It can turn a fairly large array a full 360° in about 45 seconds (about 2800 kb-inches of torque).The enclosure is a 10″ aluminum chef’s stock pot. Now that the rotator is functioning, I’ve turned my attention to a controller. Your Arduino-based project seems to be exactly what I need.

    The gear motor operates on 28 volts has a stall current of 5 amps, so I think I need a more robust controller than the standard Arduino shield. I’m a complete newcomer to the Arduino world, so please forgive what are certainly naive questions. In researching online, I have found a board that combines an Arduino development board and an H-bridge capable of handling up to 40 amps surge per motor, and up to 30 VDC supply. (This is the T’Rex board sold by SparkFun; see https://www.sparkfun.com/products/12075.)

    My questions are: is there any reason to think that this wouldn’t work to provide the foundation for a heftier version of the controller that you have created? And, are there better, or cheaper, hardware implementations of which I should be aware?

    thanks and 73,

    • Hi Lew. There are several amateurs using H bridges with my controller, however most of them use Arduino Unos, Megas, or their own homebrew Arduino board using a bare Atmel ATMEGA chip. I’m not familiar with the T’Rex, however it looks like they’ve integrated an Arduino controller with the H bridge electronics, along with other things. My code probably could be made to work with it. At a quick glance I see the functionality is I2C controlled. However, this board is probably overkill. There are H bridge motor control shields available that connect to a stock Arduino Uno or Mega. I use Megas for development these days due to the extra memory, and there’s a cheap source for them (SainSmart).

      I see the “Arduino project” motor board handles only 2A per channel / 4A total, so that board isn’t robust enough. I’m sure we could probably locate a third party one that can handle 5A.

      There are several folks on the Radio Artisan group with experience with H bridges and hefty rotation systems. I’d recommend you join and see if you could get some advice there: https://groups.yahoo.com/neo/groups/radioartisan/info In the meantime I’ll do some Googling…

      • Googling around, I’m actually liking the packaging and price of the T’Rex board more. It seems like a pretty good deal. I looked at the sample code a little more and it looks like motor control can be achieved without using I2C commands and just mapping the appropriate control pins. I need to look it over more, but I think you can probably get away with customizing the rotator_pins.h file in my project to make this board work.
