LEO Satellite System Part 3 – Final Installation And First Contacts


Eggbeater Antennas And Preamps SystemsOn Tower

Eggbeater Satellite Antennas And Preamp System On Tower

With some help from Matt Strelow, KC1XX  of XX Towers, we’ve gotten our LEO Satellite Antennas and Preamp System installed on our tower. We installed the antennas on a sidearm at about 80 ft and installed the preamp system (the upper left gray box) next to the antennas on the tower. The design and construction of our LEO Satellite System was covered in the Part 1 and Part 2 articles here on our blog.

Hardlines At The Tower

Hardlines At The Tower Base

I choose 7/8″ Heliax Hardline Coax (Andrews AVA5-50) for the feedlines between the antennas on the tower and the shack. I choose this type of cable to hold our losses to end-to-end to about 1.0 dB for the 432 MHz side of the system. Our Icom IC-9100 Transceiver which we will use for satellite work provide 75W of output on the 70cm band which results in a maximum of about 45W at the antenna – plenty of output power for LEO satellite uplink work. The end-to-end loss on the 144 MHz side is about 0.6 dB resulting in 85W out maximum from 100W in. The antennas were connected to the preamps and through to the hardline coax cables using short LMR-400UF coax jumpers and crimp-on N-type connectors were used throughout the system. The conduits that are buried under our lawn had plenty of capacity for the two additional hardline cables (the lower pair of large coax cables in the picture above). I also routed the control cables for the preamps through one of our smaller conduits.

Hardline Terminations At Shack

The hard lines (cables with orange and purple tape) were terminated with N-connectors and the shack entry end through grounded PolyPhaser Lightening Protectors.

VHF - UHF Antenna Switching Console

VHF – UHF Antenna Switching Console

The two sides of the LEO Satellite Antenna and Preamp system were terminated on our VHF – UHF switching console in our shack. The console uses Hofi-Technik Rotary UHF Antenna Switches to allow selection of the LEO Satellite Antennas as well as our M2 Antenna Systems 144 MHz and 432 MHz Yagis and a Diamond X-300NA 2m/70cm ground plane vertical which we use for repeater work.

Preamp Control Cable Terminatons On Tower

Preamp Control Cable Terminations On Tower

We also terminated the control cable from our Preamp System on Control Line Static Suppressors at the base of our tower.

Preamp Sequencers

Preamp Sequencers

The Preamp Control Cable was routed to a pair of M2 Antenna Systems S3 Sequencers (top units in the picture above) to enable proper Tx/Rx sequencing to protect the tower mounted Preamps from damage during transmit. These units allow the 144 MHz and 432 MHz Preamps to be turned on/off separately as well as enabling the noise test function on the 144 MHz preamp. With all of the installation work done, I confirmed that the SWR reading on both antennas was in specification at the input to the IC-9100 Transceiver and that the both Preamps work working (via an observed increase in noise level) when they were turned on.

Nova For Windows (FO-29 Satellite Pass)

Nova For Windows (FO-29 Satellite Pass)

The final step was to install the Nova For Windows program and download the latest Keplerian Elements for the HAM satellites that are currently operational. Nova For Windows allows me to determine when a given satellite is making a pass that covers both my QTH and the area where I want to try to make contacts. The program can also predict future passes which makes planning satellite operating times easier. The picture above shows the footprint of the FO-29 and the ISS during a pass over my location.

Fuji Oscar FO-29 Satellite

Fuji Oscar FO-29 Satellite

On the day and time that I tried to make my first contacts, only satellites with Linear Transponders were making useful passes overhead. I choose to try my first contact through FO-29 (Fuji Oscar 29) which is a V/U Mode (145 MHz uplink/435 MHz downlink) satellite.

First Satelllite Contact - EA1QS In Spain

First Satellite Contact QSL – Pablo, EA1QS In Spain

With my IC-9100 setup in Satellite/SSB Phone mode to transmit and receive on the proper frequencies and side-bands and with the Tx and Rx sides set to track each other (this is one of the useful satellite Features provided by the IC-9100), I began by locating a clear frequency on FO-29’s transponder and transmitting on the uplink while adjusting my Rx offset until I could hear my own transmissions coming back from the bird. Once I found my receive frequency, I began looking for a station to work. As good luck would have it, I found Pablo, EA1QS in Spain and made my first contact! It took some care to stay on frequency during the brief contact as the doppler shift associated with the path through FO-29 was changing fairly rapidly.

I also made two contacts with W1AW/9, the ARRL Centennial QSO Party Operation in the state of Illinois, USA. I made these two contacts through two different satellites. The first contact was made through VUSat VO-52, a U/V Mode (435 MHz Uplink/145 MHz Downlink) satellite and the second one was made using FO-29 again. I was quite fortunate to make the contact through VO-52 as its batteries failed and the bird went out of service just 12 days after my contact was made.

M2 Antenna Systems 70cm and 2m Yagis On Top Of Our Tower

M2 Antenna Systems 70cm and 2m Yagis On Top Of Our Tower

My early experiences with our new LEO Satellite System have been good. The M2 Antenna Systems Eggbeater Antennas and tower mounted Preamp System work quite well when the Satellites being worked are 30 degrees or more above the horizon. I can use our weak signal 2m and 70cm yagis (top two antennas shown above) and the associated tower mounted Preamp Systems (two grey boxes just below the top of the tower) for Satellite passes that are below 30 degrees. This mode of operation will require computer tracking which I can do via Nova For Windows or the Ham Radio Deluxe Satellite Software both of which I already have. I plan to try this combination in the future and will provide additional setup and operational results for this configuration sometime in the future.

Its been a very busy summer and I have not as much time to operate using LEO Satellites as I would like. With WRTC 2014, the ARRL Centennial Convention over, and the 13 Colonies Special Event and W1AW/1 New Hampshiree portable operations completed, I hope to have more time to devote to Satellite Operation. It’s a lot of fun to make contacts through satellites and this mode of operation will give us the chance to learn some new skills.

Operating as W1AW/1 Part II – ARRL Centenial QSO Party


ARRL Centennial Celebration Logo

ARRL Centennial Celebration Logo

I was fortunate to operate as one of the W1AW portable stations as part of the ARRL Centennial QSO Party again this past week. The first time the state of New Hampshire was on, I was only able to devote a limited amount of time to this operation. This time, I was able to set more time aside and operate about 4 hours on each of 6 of the 8 days that W1AW/1 New Hampshire was on the air this past week. During this time, I was able to make 1,925 contacts averaging a little over 120 QSOs for each hour that I operated.

The table above shows the final stats for my operations as W1AW/1 NH this past week. I mostly concentrated on the SSB Phone mode with a bit of RTTY operations on the last day. As one would expect, 20m and 40m were the most popular bands.

I encountered pileups on all of the days that I operated with the largest ones being on the first evening on 20m We had a significant solar CME event during the operation and subsequent Auroral activity which created some interesting band conditions. In particular, almost all of the 10m and 12m contacts were done on Thursday and Friday evenings using backscatter propagation. I was unable to hear much with my antennas pointed at the folks that I was trying to work on 10m and 12m so I tried pointing the beams directly south to test backscatter propagation. I also asked the folks in the pileup to do the same. This mode of operation resulted in about 350 QSOs on 10m and 12m! This was also great news for the close-in stations as this mode of propagation allowed folks in adjacent states to work New Hampshire on the higher bands.

It was great fun operating as W1AW/1 New Hampshire this past week. I wish there would be another chance to do this but we’ll have to wait awhile for the ARRL’s next big birthday to come around.

AB1OC’s 2014 CQ WPX SSB Contest Results – Another Station Goal Met


2014 CQ WPX SSB Results

2014 CQ WPX SSB Results

The CQ World Wide WPX Contest is one of my favorites and 2014 was another improvement year for me. This was the first year where I was no longer in the “Rookie” (<3 years licensed) category. I received a nice surprise in my email today – a certificate with a first place finish in Area 1 in the USA, fifth place overall in North America and #20 in the World in the Single Op High Power All Bands category in this contest. This realizes another of our basic station design goals – “to finish in the top 20 in some major contests”.

Contest QSO Summary

Contest QSO Summary (from the Athena Tool)

There are several things that worked together to help me improve my score in this contest over the 2013 total of 1,883,448 points. First, thanks to work on operating technique, my accuracy improved considerably to a respectable overall error rate of 2.8% (this is more than a 2X improvement over 2013). Secondly, our work on station automation plus better receiving equipment for the low bands worked together to provide a nice improvement in my results on the 80m band. Band conditions were also very good during this contest which helped to improve my run rates and multiplier counts. I’ve also been working hard to improve my SSB phone operating technique through participation in other contests and on-air events like The 13 Colonies Special Event. I operated for most of the allowed contest period but could have put in a few more hours of “butt-in-chair” and perhaps moved up a spot or two in North America (the difference in the final scores between places #3 and #5 in North America was only 854,958 points).

All this said, I am very happy with my results in this contest and my progress as a SSB contester in general. Anita (AB1QB) and I are continuing to work on both our skills as contest operators and our station and I hope we can continue to improve quickly.

6m VUCC And 9-Band Worked All States


6M VUCC Operating Award

6m VUCC Operating Award

The 2014 Es Season was my first chance to focus on operating on 6m. To help provide motivation, I set a goal to work and confirm enough Grid Squares on 6m to earn a VUCC Operating Award. After some time to confirm and for the ARRL to process everything, my VUCC came in the mail this past week.

6M VUCC Grids Worked And Confirmed

6m VUCC Grids Worked And Confirmed

The 6m Es Season this summer was a good one for me. I worked and confirmed over 150 Grid Squares on the Magic Band including my first contacts with the west coast of the USA and with Europe. The picture above shows my progress on 6m Grid Squares to Date (the green ones are confirmed, map via WG7J’S GridMapper website). I have also completed checking for an additional 50+ Grid Squares and should be receiving my 150 Grid endorsement for the VUCC soon. I guess I’d have to say that I’ve gotten “the bug” for the Magic Band this season.

5 Band WAS Operating Award

5-Band WAS Operating Award

The WAS award is often on of the first operating awards that HAMs in the United States pursue. It is a great award to develop some sound operating skills, prove in your HF station and make some new friends. The ARRL Centennial QSO Party with W1AW portable stations operating from each of the 50 US states provides a great opportunity to pursue WAS awards.

I’ve also been working on the contacts needed for a 5-Band Worked All States Award for some time now and I decided to focus on completing the contacts needed for this operating award last week. This probably seems like an award that should not be too difficult for a station in the United States and that is mostly true. There are two things that make this award a challenge – 1) working states that are “close-in” on the high bands like 10m and 15m, and 2) making contacts with less populated states like North and South Dakota, Montana, etc. especially on 80m.

Band Conditions (Or When Not To Operate)

Band Conditions (Or When Not To Operate)

The close in states like Vermont on 10m were some of the last ones that I needed along with a contact with North Dakota on 80m. As usual, I picked one of the worst days this year conditions-wise to complete the last few contacts. Rob, AB1NJ in Vermont helped me out with his state on 10m using JT65 and I worked W1AW/0 in North Dakota on 80m SSB to complete the last one needed for the 5B WAS.

I really enjoy operating on the WARC Bands and I often make 50 or so contacts in an evening on these bands. I have also been operating a lot on the Top Band (160m). At this point, I only need 3 more contacts (Montana on 80m, Nebraska on 30m and New York on 12m) to complete a 9-Band WAS (5B WAS plus WAS on 160m, 30m, 17m and 12m). I am planning to wait until I complete these and for all of the needed contacts to confirm to send in the paperwork for the 9B WAS.

I hope to perhaps someday make it to a 10-Band WAS, working all 50 states on 6m. At present, I’ve worked and confirmed 41 states on 6m but I know that Alaska and Hawaii will be very difficult during this solar cycle unless there is some extraordinary propagation event on 6m.

I find the pursuing operating awards provides good motivation to get on the air and work less common modes (like JT65) as well as to learn about and practice unusual operating techniques like HF Backscatter which I have used to work close in states on the high bands. Another benefit to this effort is that it has encouraged me to upgrade to Joe Taylor’s (K1JT) latest WSJT-X Software for working JT65 on the HF bands. Look for an article on WSJT-X here in the near future.

World Radiosport Team Championship 2014 Experiences


Hollis Site Support Team And Referee

Hollis Site Competitors, Referee And Support Team

Anita (AB1QB), Scott (NE1RD) and I had the opportunity to serve as site managers for the WRTC 2014 competition site in Hollis, NH. Our site was one of 65 sites in New England USA (and the only on in the state of New Hampshire). This gave us a chance to be part of the WRTC 2014 event and to meet some of the competitors, referees and the event organizers. WRTC has been called the “Olympics of Amateur Radio” because it brings together the very best Amateur Radio Contesters in the world to see who is the “best of the best”. Here’s a summary of what WRTC is all about from the WRTC 2014 Website:

“The World Radiosport Team Championship (WRTC) is held every four years and consists of 50+ two-person teams of amateur radio operators from around the world competing in a test of operating skill.  Unlike most on-the-air competitions, all stations are required to use identical antennas from the same geographic region, eliminating all variables except operating ability.”

Each competitor must qualify based upon results in selected contests over a period of 3 years. There were a total of 63 teams which participated in the event. It is a tremendous achievement just to qualify for WRTC. Each qualifying competitor selects a second person to make up their team. The competitors at our site were Julio Henriquez, AD4Z and Dan Thompson, W4UH. Our referee was Alex Orlov, RW4WR from Russia. We really enjoyed getting to know Julio, Dan and Alex. The stories that they shared and the information and tips they gave us a relatively inexperienced contesters will stick with us forever.

 

WRTC 2014 Competition Sites

WRTC 2014 Competition Sites

The WRTC 2014 competition was held on July 12-13, 2014 as part of the IARU HF World Championship contest. A great deal of effort was put into selecting and building 65 competition sites for WRTC to ensure that they were as equal in terms of propagation, antennas and configuration as possible. WRTC provided all of the antennas/feedlines, generator power and a tent for each site and each team of competitors supplied their own radios and supporting station equipment.

WRTC Station Kit In Transit

WRTC Station Kit In Transit

Preparations for WRTC 2014 have been in progress for several years now including planning sessions, station and site tests, team formation and training. All in all, the event is a tremendous planning and logistical effort. Doug Grant, K1DG was the leader and chief evangelist for WRTC 2014. Doug and his team did a tremendous job in making WRTC 2014 happen.

Our part of the WRTC experience began with the pickup of the station kit for the Hollis, NH site on the Wednesday before the event. The station kit consists of a 40 ft Rohn 25G tower, beam/wire antennas, feedlines, generator, tent and miscellaneous equipment.

TX38 Tri-Band Beam Assembly

TX38 Tri-Band Beam Assembly

Ed, K2TE and our “beam team” were at the Hollis, NH site bright and early on Thursday morning to put up the tower and antennas. The heart of the WRTC 2014 antenna system is the TX38 Tri-Band Beam which was designed for WRTC 2014.

Here’s a picture of the assembled beam and tower ready to be pulled up and into place at our site.

Tower Going Up!

Tower Going Up!

The picture above shows the tower going up. The Falling Derrick System that was developed for WRTC is quite ingenious and it raises the 40 ft tower and beam antenna with very little effort. Each beam team was specially trained in the use of this system to ensure safe setup and takedown of the tower and antennas at each site.

While Ed and the team took care of the tower and antennas, Scott, Anita and I setup the tent, generator, feedlines and “crew tent” at our site. The picture above shows the completed site ready for our competitors.

WRTC Station Radios And Equipment

WRTC Station Radios And Equipment

Julio, Dan and Alex arrived at our site after the site drawing at WRTC headquarters on Friday and proceeded to setup and test their station. As you can see, they brought quite a sophisticated setup! They used Ten-Tec Orion II radios, a microHAM band decoder and antenna switching system and PCs running the N1MM Logger to create a modern, state of the art multi-two contesting station at our site. WRTC competitors used a variety of different radios to compete in the event. You can find a summary of the radios and software used by the competitors here. The Elecraft K3 was the most popular transceiver and a combination of the Wintest and N1MM loggers were used most of the competitors.

WRTC Monitoring System

WRTC Monitoring System

The WRTC 2014 organizers did some custom design work to facilitate the event. Shown above is the WRTC monitoring system. This system is used by the referee to monitor the power levels of each operator’s radio to ensure that the 100W WRTC power limit is not exceeded. The referees can also monitor the audio from each operator simultaneously and a recording of these audio streams for the entire contest period is also made. All of this is done in the interest of ensuring a fair contest and for judging purposes as needed when the event is complete. A device also monitors the logging streams from the competitors computers to create a live, real-time scoreboard on the web. The scoreboard uses an innovative data collection method developed by Dave Pascoe, KM3T and Bob Raymond, WA1Z to “sniff” the logging information being exchanged by the competitors computers. The data extracted in this way is fed via cellphone data connections to the WRTC headquarters to update the teams scores on the web in real-time during the contest.

The Big Moment - Our Station's Callsign

The Big Moment – Our Station’s Callsign

On Saturday, just before the competition began, Alex our referee opened the sealed envelope which contained our site’s callsign which was W1T. As with all things about the event, the callsigns were not disclosed to the operators until just before the contest began to ensure that none of the operators specific callsigns were known to others.

Julio (AD4Z) Operating

Once the contest began, our team was all business. Julio is shown above operating CW. He is an amazing operator and can easily operate at 40+ WPM speeds!

Our site was one of the public access sites for the event and we had quite a few visitors from the press and local HAMs who were interested in seeing what WRTC 2014 was about. The event also received quite a bit of media coverage, some of which can be viewed here.

The final results were very close with only 118,425 points separating the 3rd through 5th place teams. To give you an idea of how close this really was – only 6/10 of a multiplier or about one minute of operating time separated the 3rd and 4th place teams! Some of the operators achieved peak rates of over 300 contacts per hour. This is very impressive considering that Field Day style stations with 100W output were used by the competitors.

Our  WRTC 2014 experience was a very memorable one. It was a great combination of amazing people, the best contesters in the world, great application of Amateur Radio technology and some of the best logistics and organization of a large event we’ve ever seen. Truly an Amateur Radio experience of a lifetime!

2014 Thirteen Colonies Special Event Operations


13 Colonies Special Event QSL Card For K2K New Hampshire

13 Colonies Special Event QSL Card For K2K New Hampshire

The 13 Colonies Special Event had another record year, completing over 108,800 contacts around the world during the 6 days of the event. This was about 25% more contacts than last year. We added the WARC bands to our operations this year which provided folks a chance to work several US states on these bands. This, no doubt, helped to increase interest in the event. The NH Operators had a good year this year completing over 9,000 contacts. I operated mostly SSB phone on 160m – 6m and made over 6,800 contacts during the 6 days of the event.

2014 13 Colonies QSO Statistics for the K2K NH Hampshire Stations

I thought it might be interesting for our readers to see how an operation like this breaks down in terms of bands and modes. The table above provides these stats for this year’s K2K NH operation. As you can see, the daytime band activity reflects the state of the solar cycle with most contacts being made on 20m, 17m and 15m. Operations on the 40m band are primarily during nighttime and are essential for many folks in the states close to New Hampshire to make a contact with us. SSB Phone is usually the most popular mode in this event with CW also being quite popular. It’s a little hard to grasp the diversity of the contacts that stations make during an event like this. Here are some additional stats for our operation in NH this year:

  • DXCC’s Worked – 82 (A good portion of a DXCC – not bad for a “US” event.)
  • DXCC Band Points Worked – 263 (A band point is a given DXCC on a unique band.)
  • CQ Zones Worked – 27
  • Unique Callsign Prefixes Worked – 1,061
  • Worked All 50 US States On The SSB Phone Mode
  • US Counties Worked – 1,416
  • IOTAs Worked – 60
  • 6m Grids Squares Worked – 94 (Almost a VUCC! Some DX from EU in here.)
  • Contacts Made To All 6 Continents

As you can see from this list, the event has become quite popular with folks outside the United Sates. There are quite a few DX operators that complete a sweep, working all 13 Colonies and the two Bonus Stations (WM3PEN and W3FT).

6m Opening During The 13 Colonies Special Event

6m Opening During The 13 Colonies Special Event

We had some very nice 6m Es Openings during the event. I worked a couple of these as K2K making about 200 contacts on 6m and working 94 unique grid squares – almost a VUCC on 6m! Amazingly, the conditions where good enough to generate a pileup for the duration of one of these openings. This was the first year that I have had the chance to focus on making contacts on the Magic Band and the  6m openings during the event were a nice chance to make some more contacts on 6m.

AB1QB's 13 Colonies Sweep Certificate

AB1QB’s 13 Colonies Sweep Certificate

Many operators who participate in the event do so with the goal of working all 13 Colonies and the two bonus stations for a clean sweep. Ken Villone, KU2US is the event coordinator and he provides a nice certificate each year for folks who work one or more of The Colony Stations. Anita, AB1QB completed her sweep this year and the picture above shows the nice certificate that she received for doing so. If you worked one or more of the 13 Colonies Stations, you can apply for a certificate here.

K2K New Hampshire QSL!

K2K New Hampshire QSL!

Many folks work the event to collect our QSL cards and for Worked All States Award Credit. This results in quite a few QSL cards being sent! The picture above shows the outgoing QSL response about 1 week after the event. This batch contained about 700 cards. The total QSL’s we will send in response to 2014 operations as K2K New Hampshire will be approximately 1,000 cards. We added ClubLog OQRS, LoTW and eQSL as alternatives to confirm contacts with the K2K New Hampshire Stations this year and many folks have used these to confirm contacts as well.

As the 2014 13 Colonies Special Event and the follow-up QSL’ing draws to a close, I have many great memories to look back on. I am already looking forward to the 2015 event. Ken has created a really great looking certificate for the 2015 event and you can see a preview here. I hope to contact many of readers as part of the 2015 13 Colonies Special Event!

Experiences From The ARRL Centennial Convention In Hartford, CT


ARRL Centennial

ARRL Centennial

The ARRL has been celebrating its 100th year this year with a variety of events. One of the biggest was the ARRL Centennial Convention in Hartford, CT this month. Anita and I were fortunate to be able to attend this excellent event and I wanted to share some of our experiences from Hartford with our readers. We began our Centennial Convention experience by attending the Contest University session that was held on the first day. No matter how many times we attend this excellent training day, we always learn some new things and techniques that we can practice in our contesting efforts.

Vendor Show

Vendor Show

One of the key things to do at the Convention was the excellent Vendor display arena. In addition to an all-out booth run by ARRL, many of the major radio and equipment vendors were present. Beyond the Dayton Hamvention, this was one of the best vendor displays of this type that we’ve had the pleasure to attend.

Forums And Presentations

Forums And Presentations

The best part, by far, for us were the excellent Forums and Presentations that were part of the convention. The ARRL managed to line up some of the most noted experts in the Amateur Radio Community to speak on a broad variety of topics.

Joe Taylor's WSJT Presentation

Joe Taylor’s WSJT Presentation

One of the best was Joe Taylor’s (K1JT) excellent presentation on the weak signal digital protocols that he has developed and the software that he has created to enable the Amateur Radio community to make contacts using the Moon, Meteor Scatter, and other means in very marginal probation conditions. You can find out more about Joe’s work in this areas on his Home Page.

Gordon West 2M Tropo Presentation

Gordon West 2M Tropo Presentation

Gordon West, WB6NOA gave an excellent presentation on Tropo Ducting Propagation on 2M. Gordon is very knowledgeable on this topic and he is also a very entertaining speaker!

Fred Lloyd's QRZ Presentation

Fred Lloyd’s QRZ Presentation

Fred Lloyd, AA7BQ founder of QRZ.com gave an interesting presentation on the history of QRZ.com and what he is doing with some new online logbook and QSO confirmation capabilities on his site.

cott Andersen's DXpedition In A Backpack Presentation

Scott Andersen’s DXpedition In A Backpack Presentation

B. Scott Andersen, NE1RD gave a cool presentation on Lightweight DXpeditioning. Scott has perfected a practical approach to lightweight DXpeditioning and has also contributed much to the use of the Buddipole Antenna System via his work with that system as part of his operations (check out Scott’s excellent book – Buddipole In The Field).

I was also fortunate to have the opportunity to speak about Station Design and Construction as part of the program. You can check out our material on this topic via the overview post here or download a copy of the presentation that we gave in CT.

There we several fun dinners and keynotes through the event. One thing that was very special was the presentation of awards to the ARRL from other Amateur Radio organizations around the world. The picture above shows some of the awards received by the ARRL.

There was also a QSL Card Wall at the event. Can you find the callsign of someone that you’ve worked in the picture above? There are a few rare ones in here.

All in all, the ARRL Centennial Convention was one of the highlights of our Amateur Radio experience to date. Anita and I feel very fortunate to have been part of it.
