K3 at SE0X gets major upgrade

K3 KSYN3A Upgrade OK

The Elecraft K3 transceiver at SE0X is an early first batch model. It was ordered within days from the K3 announcement at the Visalia DX convention 10 years ago. Many improvements has been introduced over the years and most of them have been implemented in our K3. Read more ›

SE0X CW Skimmer Back Online

SE0X Skimmer

Our CW skimmer is finally online again after a series of both software and hardware problems. It all started with with Windows automatically upgrading to Win 10 which lead to network problems. The WiFi link was replaced with Ubiquity equipment which seemed to cure the problem. Read more ›

Remind me again…

Why am I always working on antennas in November, right at the start of the wet and windy season!

 

Posted the above video on Twitter. I have to admit it doesn’t look as dramatic when seen on video, but when below the tower the beams swing back and forth like a mobile whip on the highway. Read more ›

Keeping your competition on a distance

Screen Shot 2015-07-13 at 14.00.23This is a grim example how to keep your competition on a distance! I won’t mention calls, but this screenshot is from the IARU HF contest this past weekend and this is a HQ station. If you look closely to the waterfall display you notice the splatter lines at least 30 kHz down.

Multi-One Low Power in WPX SSB

WPX SSB a year ago, in 2014, was a success for SE0X. Propagation was fabulous and we where able to set a new SM record in the Multi-Two category. This year we wanted to try something new and decided to enter in Multi-One Low Power where there presently is no Swedish record. Reaching the current EU record would be a stretch with the current propagation, but we like a challenge so we chose this as our goal. Read more ›

QRP action in CQ-160 SSB!

Working a 160 meter contest QRP is much more fun than you might think! A few weeks ago I worked the CQ-160 SSB contest using 5 watt QRP power. I logged more than 200 QSOs and the claimed score is almost half the number of my SM Low Power record and more than a third of my High Power and High Power Assisted records. Read more ›

8Q7BM Photos

Spending two weeks in the Maldives in January was an unforgettable experience. Not only because of the blue ocean, white sand and warm sun. 160 meter contesting and DX’ing barefoot with a compromise antenna posed a challenge very different from the usual big signal-work-them-all experience from home.

Below are a few photos from 8Q7BM.

Amazing Propagation in WPX SSB

A multi operator effort with international operators have become a tradition at SE0X in WPX SSB. This year the team consisted of four nationalities, DD1MAT from Germany, SM0MDG and SM0MLZ from Sweden, TF1ZA from Iceland and W1UE from USA. The team set its target at beating the 2011 SM record in the Multi-Two category, a record set by a previous team effort from SE0X in 2011 (7S0X).

SE0X is a “small station” but with a great location. We have only a fraction of the aluminium compared to some of the local super stations. But at SE0X we have the benefit of being close to the sea, our antennas are surrounded by brackish water. Good propagation is also helpful, we need the stateside runs on higher bands to be able to build competitive scores. Our 5 element OP-DES mono-band Yagi really gets the job done in most situations, but when 10 meter opens big things really gets interesting and almost anything is possible.

This year we invited W1UE Dennis to participate in the team via remote. Dennis already had the necessary hardware, a K3/0 and a Remoterig interface which is the system SE0X uses for remote control of the station. After a little testing we decided the transatlantic connection was good enough, and we scheduled Dennis for several shifts on station one.

SE0X have been remotely controlled in contests for three years, but never done before with an operator physically outside SM. We wanted to see how the bigger latency and logistics with a mixed local and remote team would work out. Dennis logged 876 contacts from his home QTH in Marlborough, Massachusetts. N1MM’s ‘Talk’ feature and a Skype chat was used to communicate between Dennis and the operator on Radio 2 when needed. Dennis was also able to follow the contest by listening in to the other operators working their shifts on the remote controlled K3. Except for some intermittent dropouts, the transatlantic internet connection was reliable and the remote operation part of the contest very successful.

WPX this year will go into the SE0X history book. Propagation was great, higher bands where in excellent shape. 15 meter really dominated the log on Saturday while 10 meter took over and rocked on Sunday. 20 meter was the goto high band for NA runs overnight. Lower bands where not as good this time, probably because most operators where busy on higher bands even during dark hours.

The result of the team effort in WPX SSB 2014 is amazing!  The band breakdown shows that 15 meter was the strongest band overall with a large amount of North American and Asian DX. 10 meter was also very strong ranking number two in contacts but with a bigger share of DX than any other band.

WPX SSB 2014: Continents by Band

Our goal was to beat the 2011 record at 8.410.650. Not only did we beat the record, but we where able to almost double the score. With a claimed score of 16.297.886 points the team left SE0X early Monday morning with a broad smile on their faces.

Thanks to everyone in the log, we couldn’t have done it without you!
