The skimmer receiver at SE0X has been offline a few weeks. Some of the local species find RG6 coaxial cable delicious. Our 100 meter coax was temporarily repaired this past winter after being chewed off. This summer when replacing the coax, I found deep cuts caused by animals in several places were the coax crosses trails.
The new coax now cross these trails inside a rubber hose which hopefully will protect the coax a little better. Protecting your expensive coax against the wild life is definitely something to if your station is in the woods. Luckily the SE0X skimmer is located away from the main station. At SE0X wild life is limited to birds, fish and the occasional fox who doesn’t mind a swim.
Skimmer spots are being reported to the Reverse Beacon Network by SE0X and can been seen here.
Challenged by the QRM picked up by my omni directional active RX vertical when trying to work TL8TT on Topband, I decided it was time for a directional RX antenna pointing south in addition to my N/W and N/E Pennants. I had a transformer and termination resistors collecting dust so I decided to throw out some wire to make a short BOG, Beverage On Ground. Since I didn’t have any proper common mode chokes at hand I just wound about 10-12 turns of the coax around a FT-240-31 core. How does this quick fix compare with a proper RF choke? Read more ›
CQ 160 is one of my favourite contests. The goal this year was set to break the SM record in SO-HP Assisted. In addition I also wanted to beat my own score from 2010 in SO-HP (unassisted). Reasonably well prepared, somewhat rested and with the gear in shape I was ready to take on the challenge. This is the story of SE0X in CQ 160 CW 2017, keep on reading to see if I succeeded in hitting my goals. Read more ›
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 ›
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 ›
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 ›
Earlier this month I was logging more than one thousand contacts in the IARU HF contest using an SDR transceiver. In this blog post I will share my experiences of this modern approach to contesting. Read more ›
The IARU HF Contest this past year was a lot of fun despite the bad band conditions. More than 1000 QSOs where logged in 22 hours of operating time. Here is a short summary with results. Read more ›
This 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. Read more ›
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 ›
