CQ WW WPX RTTY Contest

Toes our Maine Coon Cat

Toes our Maine Coon Cat

I finally made my first ever RTTY contacts during the CQ Worldwide WPX RTTY contest this past weekend.  The SignaLink, N1MM and MTTY worked flawlessly during the contest. Working RTTY is certainly a lot different experience than operating CW or SSB.  RTTY signals are more challenging to tune but once correctly tuned the text magically flows across the screen.

During the contest just clicking on the various pieces of information in the MTTY receive window (callsign and exchange) automatically populates the correct fields in N1MM.  You then send your own information, wait for a TU from the other station and hit return to move on to the next contact.  This was very enjoyable.  After a while you get into the “zone” and the time just flies by.

During the contest I noticed that our Maine Coon cat is not a fan of RTTY.  Normally, “Toes” will hang around in the shack when I am operating CW.  In fact he seems to enjoy winding around my legs or laying on the bed next to my shack and observing the activity.  He didn’t come near the shack while I was operating RTTY this weekend.  Maybe the weird RTTY tones hurt his ears or perhaps cats understand CW?  I vote for the latter!  In the future I need to watch what I send, because “Toes” may be listening in.   Here is a summary of my results:

Good Hamming but Poor Antenna Repair Weather

Iceberg in Our Pond

Iceberg in Our Pond

The weather this winter has been good for hamming but not good for antenna work. Our winter has had one of the most sustained cold periods I can remember.

The photo at the right shows the ice in our 1/2 acre pond.  The iceberg in the middle was formed by the water falling from our floating fountain and freezing on the frozen pond surface.  This is the first time I have seen this much ice build up around the fountain.  Normally the fountain will keep an 8 to 10 foot diameter area open around the fountain.  Right now the only open area is from our air pump which is keep about 3-5 foot area open (right side of photo).

Since late December we have had a cyclic weather pattern of snow followed by sub-zero temperatures followed by warming to the mid-20’s followed by more snow and more sub-zero weather.  This weather pattern has been quite unusual for us.  Our more typical winter would be a sudden cold snap in late December or early January with one or two 6-8″ snow falls followed by a warm spell in January or February.  We would also sometimes have a snow fall sometime in March followed by a gradual warming trend until Spring arrives in April.  Of course the sustained cold is also evident in my heating bill!  I’m hoping for an early Spring because I’ve had enough winter for this year.

First RTTY Contacts – CQ WW WPX RTTY

Well I finally had a chance to test my RTTY setup. I decided making a few contacts in the CQ WW WPX RTTY contest would be a good test of my RTTY hardware and software. For Hardware I’m using a Tigertronic’s SignaLink USB interfaced to my ICOM 756 Pro III.  For software I am using N1MM with MTTY and 2Tone setup in the Digital Interface.

It took a little time to determine the best arrangement of all the N1MM windows on my monitor because the MTTY and 2Tone take up quite a bit of screen space. After I had the N1MM working with MTTY and 2Tone I downloaded a key file for the CQ WW WPX RTTY contest.

I also sent out a request for pointers to fellow hams in the Society of Midwest Contesters.  Several experienced RTTY operators sent this rookie some key pointers.  I’ve summarized some of them below:

  1. Watch your ALC level
    Do not allow the ALC to activate because it can distort your RTTY signal; making it hard for others to copy.
  2. De-rate your output power
    RTTY has a 100% duty cycle when you are transmitting.  This can stress transceiver and amplifier output stages.  It is probably not a problem to operate a full power if you are doing Search and Pounce, but if you are going to try running a frequency it is best to reduce your power a bit unless you are certain your transceiver and amplifier can handle 100% duty cycle. It is advanced that you check your transceiver and amplifier manuals for their recommendations.  In my case my setup should be able to handle the 100% duty cycle, but I chose to operate at 50% power just keep the stress low on everything in case I made some sort of rookier mistake.
  3. Keep Your Macros Short
    Don’t over do the length of macros in a contest.  You can send your call twice when calling a station and send his call followed by the report twice and your call again for the exchange.  You can always re-send the information if it is missed the first time.  The default N1MM RTTY macros for the CQ WW WPX contest are reasonably short but can be tweaked a reduce them a little more.
  4. Listen for a While Before You Jump Into the Contest
    This was valuable input because when I first start tuning station during the contest it was a very confusing.  After I had spent a half hour listening to other stations operating I had a good feel for properly tuning in stations and had a better feel for the flow of the exchanges.
  5. Never Run Compression and don’t over drive the audio
    Make sure that audio compression is turned OFF.  Having it on will make it hard to make contacts.  Also make sure your microphone gain is set just high enough to provide a clean audio signal.  Keep the audio low enough that the ALC is NEVER triggered.
  6. Add a space or CR at the start and end of your macros.
    This helps to insure that your signal will be properly synchronized to the receiving end.
  7. Make Sure Your Not Operating Upside Down
    One of the most common transmit problems is transmitting inversely or up-side-down. RTTY is polarity sensitive. Transmitting inverted means you are sending a Mark when you should be sending a Space and vice versa. This can happen if you are using AFSK or FSK. With AFSK, it could mean you are using the wrong sideband. LSB is standard but USB can be used if you have the polarity correct. Yet, most stations who send inverted are using the wrong sideband. If you are set up to transmit in LSB, sending RTTY while in USB will result in your transmit being inverted.The above information was from AA5AU’s excellent article on operating RTTY which can be found here: http://www.aa5au.com/GettingStartedOnRtty.pdf

I would like to thank all of my fellow Society of Midwest Contesters for their helpful advice for this new RTTY operator.

After following through on the above advice I finally got on the air and made my first RTTY contacts last night during the CQ WW WPX contest.  I was only on about two hours and did not set any records for rate, but I did make over 30 contacts.  I plan to get on again to day and see if I can improve my skill.  I’ll let everyone know how I ended up.

Setting up for my First RTTY Contest

I’m planning to make my first attempt to enter a RTTY contest during the NAQP RTTY contest later this month.  Since I have never operated RTTY  I have a lot of preparation to do before the contest.  I’ve been reading up on general RTTY operation and RTTY contesting.  I’ve decided the easiest way to get on the air will be to use AFSK (Audio Frequency Shift Keying) rather than true FSK (Frequency Shift Keying).  From what I have read, most of the serious RTTY contesters use FSK rather than AFSK because transceivers having true FSK offer better filter options than when operating AFSK using LSB mode. Since, to operate FSK I would have to setup an additional interface to my transceiver I decided to take the easy route for my first RTTY contest because I really don’t want to take the time build a FSK interface to my transceiver right now.  If I find I enjoy RTTY contesting I’ll probably go the next step and setup an FSK interface between my computer and the ICOM 756 Pro III.  I decided the quickest way to setup for AFSK is to use my the SignalLink USB interface which I have for operating PSK-31.

Tigertronics SignalLink USB

Tigertronics SignalLink USB

Last night I repeated the setup of the SignalLink USB just to make sure I have the levels correctly set on my computer.  After that I reduced the power on my transceiver and did some initial RTTY testing using a dummy load.  Everything seemed to be working OK so in the next few days I’m going to see if I can actually make a RTTY contact!  However before I do that I will spend some time tuning in RTTY signals to get the hang of quickly zeroing into the correct frequency.  I will also be watching the flow of RTTY QSOs so that I have a good feel for the proper procedures before I attempt to make my first RTTY QSO.    I plan to also read through the ARRL Operators Manual just be make sure I don’t make any stupid mistakes on my first attempt.

After I have made an RTTY contact or two I will need to setup N1MM to work with the SignalLink and MTTY.  I found an excellent website that goes through the complete setup of N1MM for RTTY contesting.

Here is a link to the website:  http://www.rttycontesting.com/n1mm/n1mm-quickstart-index.html.

As soon as I make my first RTTY contacts I’ll add a post describing my experiences.  I’ll also post my experiences setting up N1MM for RTTY.

Want to Work More DX ?

Complete DX'er by Bob Locher, W9KNI

Complete DX’er by Bob Locher, W9KNI

 

If you haven’t read Bob Locher’s “The Complete DX’er”  I highly recommend you read it if want to improve your success working DX.  Like many hams my ham radio activities were put on hold for many years because of career and family.  After I retired in 2008 I decided to setup my thirty old transceiver, a Kenwood TS-520 and see if ham radio was as exciting as it had been when I first got my license.  With a lot of help from my wife, we were able to string a 40/20/15 trapped dipole between two of our large yellow poplar trees.  Then, after spending some time re-learning how to tune the TS-520 I was on the air again.

At first I spent a lot of time tuning around the bands and making SSB contacts with hams around the US.  I decided it might be fun to try working the ARRL Sweepstakes like I had done as a Novice.  Since my CW skills had deteriorated over the years I figured I would start with the SSB Sweepstakes.  Working lots of stations in the sweepstakes was a real thrill.  I didn’t get a clean sweep by a long shot but I managed to work nearly as many states that weekend than I had during all of my years as a ham.

After working Sweepstakes I was hooked and wanted to try participating in the upcoming ARRL DX Contest. During the ARRL SSB DX Contest I was able to work over 40 DXCC entities; including Iceland and the Galapagos Islands.  For me,  working DX stations was a real thrill.  I decided it was time to upgrade my station and my skills.  My first purchase was Bob Locher’s The Complete DX’er.

In this book, Bob passes on his years of experience chasing DX by letting you sit in the shack with him as he works DX.  In each chapter he demonstrates specific skills that help him nab the rare ones with his Elecraft K2-10 and Skyhawk beam.  One of the key skills he teaches in this book is the importance of slowly tuning the band listening for DX stations.  He emphasizes how important it is to work the DX before they are spotted on the DX Clusters because they are much easier to work before the rest of the competition arrives; especially with a modest station.  He also explains the dynamics of a pile-up and how to increase your success rate by spending most of your time listening instead of just throwing your call into the pool with all of the other stations.  The pile up techniques Bob teaches have helped me work a lot of DX running QRP while the kilowatt stations were still beating each other up in the pileup.  It is amazing how often you can get the DX station on one or two calls if you call him just above the frequency he was listening on during his previous QSO.  This technique doesn’t always work, but it sure is thrilling when it does–which is quite often.

Even if your not a aspiring DX’er I think you will still enjoy reading Bob’s book, but if you are interested in working more DX, The Complete DX’er  will help you develop the skills to work more DX..  I find myself going back and re-reading portions of the book because even as my skills have improved I still pick up new things with each reading.

DX Code of Conduct

As I listen to some of the high profile Dx-peditions I amazed by the bad behavior that I hear in the pile-ups.  I know that all of us have probably called on a DX frequency once or twice because we hit the wrong button on our transceiver or did not know the station was working split but what I’ve heard in the past two to three years goes well beyond the common errors of inexperienced DXers.  Some of the things I’ve heard include:

  1. Deliberate jamming of the DX stations frequency
  2. Calling CQ on the DX stations frequency
  3. Sending their call sign continuously in the pile-up
  4. Continuing to send their call sign while the DX station is working another station, and of course our favorite
  5. The policemen sending UP, UP, LID, LID and sometimes even answering the caller as if they are the DX station all while the DX station is trying work stations.

I’m sure most of you could add to this list.

I know in every large group their are probably going to be a few bad apples which even a code of conduct will not cure.  However, for the rest of us the DX Code of Conduct provides a list of “good” operating practices which will not only improve our DXing success but will make it much more enjoyable working DX.

DX Code Of Conduct

DXCode_Logo_small

  • I will listen, and listen, and then listen again before calling.
  • I will only call if I can copy the DX station properly.
  • I will not trust the DX cluster and will be sure of the DX station’s call sign before calling.
  • I will not interfere with the DX station nor anyone calling and will never tune up on the DX frequency or in the QSX slot.
  • I will wait for the DX station to end a contact before I call.
  • I will always send my full call sign.
  • I will call and then listen for a reasonable interval. I will not call continuously.
  • I will not transmit when the DX operator calls another call sign, not mine.
  • I will not transmit when the DX operator queries a call sign not like mine.
  • I will not transmit when the DX station requests geographic areas other than mine.
  • When the DX operator calls me, I will not repeat my call sign unless I think he has copied it incorrectly.
  • I will be thankful if and when I do make a contact.
  • I will respect my fellow hams and conduct myself so as to earn their respect.

FT5ZM On the Air

FT5ZM  Amsterdam Island

FT5ZM Amsterdam Island

Well one of the most wanted DXCC entities is finally on the air.  After over a week of travel the team started operations today and the pile-ups were astounding.  I tried for nearly an hour to work them on 20 meters with no success.  The pile-up was nearly 15kHz wide.  One interesting thing I did was to hook up the I/Q output of the KX3 and feed it into CW Skimmer.  Within less than 5 minutes CW Skimmer had captured over 160 call signs.  Even with CW Skimmer running it was still difficult to pick the right spot to call.  I finally decided to try another time.

This evening I saw they were operating on 17m.  I went up to the shack and heard them loud and clear.  There was still a significant pile-up, but it was only about 5 kHz wide.  After about 20 minutes of tuning the pile-up I found a pattern in their operation.  After about 5 tries I finally heard my call sign and a signal report.  It was pretty exciting to work another All Time New One.

Hopefully over the next several days I will be able to work them on some other bands.  Their website is:  http://www.amsterdamdx.org/

Feel free to join the pile-up.  Just be sure to follow the DX Code of Conduct and the pile-up will be fun for all.

The Spectrum Monitor

Like many hams, I have also been interested in other aspects of radio and communication since I was a kid.  Some of my other interests include shortwave listening, scanning police and fire communications and vintage radios.  One of the best magazines which covered these topics was Monitoring Times, published by Grove Communications.  It was a big surprise last summer when Bob Grove announced that he was retiring at the end of 2013 and would be closing Grove Communications and ending the publication of Monitoring Times.

Just by luck I had just renewed my subscription for three years.  Of course Grove Communications gave all subscribers a refund for the remaining issues of their subscription.  The real loss was not being able to look forward to receiving each new issue because each issue always contained a wealth of information on scanning, ham radio, radio restoration and numerous other topics.

Fortunately, many of the writers from Monitoring Times have moved on to a new venture and are publishing an electronic magazine called The Spectrum Monitor.  The magazine contains  much of the same content that was in Monitoring Times, but with significant additions.  Since they do not have to worry about printing costs, the magazine is published as a full color pdf file which contains features not possible with a printed magazine–such as sound and video clips.  The sound clips are a nice feature well suited to those of us interested in communication.  Want to hear what that restored boat anchor sounds like?  Click on the link provided in the pdf file and you can actually hear it!

If any of you are like me and miss Monitoring Times you might want to check out The Spectrum Monitor.  Here is a link to their website:  http://www.thespectrummonitor.com/

I think you will be pleased with what you see.

By the way, I do not have any financial other interest in The Spectrum Monitor. This information is only provided because I feel there might be other hams that were also part-time or regular readers of Monitoring Times that would be interested in a similar magazine.

KX3 QRP in NAQP

Well I decided to run my KX3 in the QRP class of the SSB portion of the North
American QSO Party.  This was the first time I had ever done SSB contesting at QRP power levels.  During the 2 day warm spell we had last week, I was able to repair and re-install my 80 meter doublet which had come down during the last snow storm.

The next step was to get the KX3 ready for a SSB contest.  To setup the KX3 for the contest I had to figure out how to interface my Heil Pro head set to the KX3.  I use a headset and foot switch during SSB contests so that I can keep my hands  free to type on the keyboard.  Connecting the Heil head turned out to be straight forward because the 1/8″ headphone and mike connectors will plug directly into the KX3 mike and headphone inputs.  However,  a KX3 menu setting had to be changed to disable the mike PTT button because the 1/8″ mono phone plug on the Heil head set will enable the PTT since the KX3 mike jack is a 1/8″ female stereo jack.  Elecraft provides a menu setting to disable the PTT function for this reason.

The next thing I had to do was interface my foot switch to the KX3.  I determined that the foot switch can be connected to the KX3 through the ACC2 connector.  The only problem I had interfacing the foot switch was connecting the 1/4″ male mono phono plug from the foot switch to the 1/8″ ACC2 female jack.  Elecraft sells a nice cable for the ACC2 input which plugs into the KX3 and provides RCA female connector (to key an amplifier) and a 1/8″ female mono phone input which can be used to access the PTT function.  Once I had the Elecraft cable all I had to do was make a 1/4″ F phono to 1/8″ M phono adapter.  I happened to find an adapter cable in my Junk box so I was in business.  The only other thing I had to do was a simple menu change to tell the KX3 that the PTT should activate when the ACC2 center pin is pulled low.

I found that operating QRP in a SSB contest is a bit more of a challenge than running 100W, but I was still able to work nearly all of the stations I called.  Sometimes I had to wait in line behind the high power stations but I usually did not have to call more than two to three times.  In most cases I was answered on my first call.  The main exceptions were the rarer states such as WY and DE.  I even managed to work Alaska and Hawaii during the contest.

Here is a summary of my QRP part time Search and Pounce effort:

BAND QSO POINTS SEC
3.5 12 12 10
7 57 57 26

KX3 Tryout in Contest Mode

I used the KX3 in the North American QSO Party (CW) this weekend.  I was only able to put in a part-time Search and Pounce effort but the KX3 performed marvelously during the few hours I was on the air.

Before the Contest

Before the contest I had to interface the KX3 to N1MM.  I used the Elecraft USB cable to connect the KX3 to my computer.  The KX3 was immediately recognized by my computer which assigned it to COM 9.  I went to N1MM to setup the KX3 and discovered that N1MM can only interface to hardware on COM ports 1 to 8.  After a little investigation I discovered I could reassign the  KX3 to an un-used COM port in the range 1 to 8 using its properties dialog.  In my case I was able to  reassign the KX3 to COM port 2.  I was then was able to setup the KX3 with N1MM with no problems.

Next I had to setup the KX3.  First I connected an output from my USB Winkeyer to the external key input on the KX3.  I also had to go into the KX3 menus to tell the KX3 to treat the Key 2 input as a handkey since the external Winkey would be creating the dots and dashes.   Next I fired up the KX3 and used my external watt meter to set  the output power to 5 Watts since I was entering the QRP Single Operator, QRP category.

During the Contest

I started the contest on 15 meters because it seemed to have the highest concentration of activity early Saturday afternoon.  Once I had worked up and down the band a couple of times I switched to 20 meters and repeated the same process.  Finally, after I had finished on 20 meters I dropped down to 40 meters to try to work a few more stations before I had to quit.

The KX3 did a great job separating the strong signals under contest conditions.  Also the continuously variable passband and roofing filters did an exceptional job pulling weak stations out from between the major league contest stations.  I was also impressed by the performance of the KX3s internal antenna tuner.  The one thing I missed from my Icom 756 Pro III was the large color panadapter.  In the next few days I plan to use the I/Q outputs from the KX3 to create a panadapter display using HDSDR.  I’ll post my experiences once I get it working.

The highlight of the contest was working both Alaska and Hawaii with only 5 watts.

Here is a summary of my contest results:

Band   QSOs   Pts   Sec   Mt2

7         19        19       7      0
14         45        45    14      0
