Hi, Thnx for looking me up, SE3X - Sierra Echo 3 X-Ray, Op. Johan!

First licensed as SA0BYC, but after moving Qth within Sweden I became SA3BYC.  Since 2012 I use SE3X as Contest- and DX call. I'm not a hard-core contester, but enjoy it as well as making DX contacts. I do not put in tons of money, but tries to build a reasonably competetive station with mainly homebrew antennas. It's a hobby and just for fun you know :)

My Swedish licens (CEPT compl.) allows 1 kW legal power, every possibel mode invented, on all hambands, but I'm a 100W and HF kind of ham. My Qth;  Åre, a skiresort, 700 km north of countrys capitol Stockholm and only appr. 60 km from the Norwegian border offers very good antenna possibilities and a low QRM level. On the mountain side, 520 m asl, it's ideal for radio operation. My only two problems is AC power, max 16A - 230/400V, have to limit my use of big PA's. Second; the very strong winds and ice build-up on my antennas in the winter, have to limit antenna mast height.  I prefer to have my antennas low and always in the air - instead of on the ground after one of our many and frequent storms :)

Station:  TRX 1 - Kenwood TS-590S   TRX 2 - Kenwood TS-570D.  Other eq:  RM HLA 300+ PA, LDG AT-1000, Ps from MAAS and Kenwood, headsets from W2ENY and Heil. Software: HRD for rigcontrol and main log, N1MM Plus and Log4U for contest logging. Manual switch-matrix for TRX and Antenna selection plus MFJ-1707; auto T/R Switch for separate Rx/Tx antenna.

Mast 1 (10.5m / 35 feet):  80/40mb Inv-V.   40/15mb wire L-Vertical with elevated radials: 4@40mb and 2@15mb.  20mb wire Vertical with 3 elevated radials.

Mast 2 (9m / 30 feet):  3-el beam, 10/15/20mb fixed @280o, Doublet dipol 12/17mb, 10mb wire-Vertical with 3 elevated radials  and 2m/70cm Slim Jim for local contacts.

Other / RX-antenna:  Horizontal loop; 80,5m long, coax feed with 4:1 balun, 3-4m agl, tunes on 80-6mb. Used as Back-Up, NVIS and as RX-antenn. Works a treat for RX on 80/40 and sometimes on 20/15m - refer to it as my Beverage loop.

In contest I normally enter as SOAB LP (single op, all band low power station). I don't work SO2R, think it's a little bit over my capability. However, I work SO2V and find that complicated and efficient enough for me.

Will always be participating in as many contests I find time to betwen family and work comitments . I will try RTTY contesting during 2015. No plan set, will be ad-hoc choise of contests - Just For Fun!

Contests coming Up: 27-28/12 Canadian Winter Contest.  2015:  3-4/1 ARRL RTTY Roundup, 17-18/1 HA DX Contest, 14-15/2 CQ WW RTTY WPX,  7-8/3 ARRL Inter. DX SSB, 21-22/3 Russian DX Contest, 28-29/3 CQ WW WPX SSB.

Contesting my first year 2012: EU HF Contest, SSA MT 09, SAC, SSA MT 10, CQ WW DX, SSA MT 11, YO HF Contest, SSA MT 12.

QSL Policy and Service: I'm not a collector of paper QSL cards and strongly encourage everyone to stop this waste of paper and trees and use modern electronic QSL systems instead. All my contacts will be confirmed and uploaded to e-Qsl, LoTW and Club log on a regular basis.  If you are a paper-chaser I will only send paper QSL direct! Always use the OQRS system at Club log for ordering a Qsl card from SE3X. I just  received the new postalrates and a direct card will from nov 01-14 cost 2.50 Euro (expensive? well, it barely cover my cost).

My last 50 Qso's - Ragchew, DX and other Non-Contest Qso's from my main log; Ham Radio De Luxe.

LOTW: During my activities I have worked some countries, states and prefixes, good fun it is!  DXCC: 159 / 123 (worked/confirmed), WAS: 38 (confirmed), WPX: 922 (confirmed).

Work in Progress / Future plans - SE3X

In this hobby there always something one would like to try and every time you try something new, you learna and most of the time one get more ideas on what to do and try. My main focus is still on antennas. When I feel I have, and I'm getting close, the best set-up I can achive, then I will find something else to focus on.  Parallell to the antena work I make small changes to my station. Main focus is to try and make operation as easy as possibel. Fast and easy audio-, PTT-, band-, antenna-switching, etc. for my 2-radio set-up. Another focus area is to get QRV on RTTY and Digi Modes during 2015.

Below you find some projects and/or work in progress ... some still in the think tank.

Antenna work:

- Add Rotator @ mast 2 and increase height to 12m/40 feet (2015).

- 2-el beam 12/17m @ mast 2 (2015).

- 80mb Vertical, L-typ?  (2015).

- 160mb, L-vertical, extension of 80m vertical, traps? (long term project,  2015/16).


- Replace LDG AT-1000 with fully automatic  LDG Pro II modell (2015).

- New TX antenna remote switching (2015).

- Switchbox for auto-switching betwen radios and fasttuning of PA (2015).

- DigiMaster Pro III, RTTY, Digi Modes etc. (2015).

- Re-build all antenna feeds. Lightning protection and manual "cut off" for all coax feeders into station and switch boxes (2015).

- PA 1 kW  (2015/16).

- RF/noice proof station with toroids on all feeders, p/s, USB-lines, etc. (2015).


My "workspace"

To the left is my back-up and 2'nd radio, TS-570. Had to switch of the 2 PC screens, while they where overpowering the picture. Left screen for a Dell PC, Win 8.1, loads of memory and processor power. Right screen for a HP Win XP PC - N1MM and HRD. To the right my 1'st radio, TS-590. Both radios connected via a manual switch-matrix to the AT-1000 and SWR meter. Switching radios and antennas with a flip of a switch ... On the wall above is a mini PC with a 26" screen I use for cluster etc.

I have 3 PC connected in a schack WLAN with a common back-up harddrive, Inet via a mobile router and firewall.

I have a RM HLA 300+ power amp (under the desk) just to ensure I have a 100W output (contest LP), regardless of antenna and/or coaxlenght and losses. Another benefit with the PA is that I can run forever whitout any cooling problem. Radio only need to work at 13W output to have 100W from the amp. Amp itself then runs at 25-30% of it's capacity.

With this set-up I can move band and betwen the two radios within seconds. Plan is to add a relay switchbox for switching radio, as well as a remote switch for the antennas.

Current antennas

Mast 1; 10.5m/35 feet with my wire-antennas: 80/40m dipole on topp, 40/15m wire-vertical and 20m wire-vertical to left and right of mast.

Detail of the radiator-/radials coax mount for 40/15m and 20m wire-vertical. To fit in with mast height both 40/15m and 20m wire-verticals are L-type. Mast 2; 9m/30 feet with the latest addition to my antennas: 3 element, tribander short boom Yagi for 10, 15, 20m. Fixed @ 280 degrees until summer 2015.

My QTH and my Neighbours .. hi hi

May 26 - 2013, springtime in the mountains and time for the reindears to move betwen low- and highland. Picture taken just outside my Qth. In the background you see Mount Åreskutan, 1440 m. Thanks to "her" I am somewhat limited West-bound appr. 310-320 degree W. But I have worked W/VE 6 and 7's on 10 - 20m, guess my problem on 80m and 40m is more because poor DX antennas. Hope new antennas with lower radiation angle will improve that.

A beautiful winterday, december 15 - 2013, almost the same spot just outside my Qth, in the background you see a winter pretty Mount Åreskutan. A winterday like this makes life worth living up here!

Autumn at it's peak, september 19 - 2014, same spot near my Qth, mount Åreskutan still 1440 m. Just finishing my vertical for 40m, hoping to "jump" over "her" this winter.

These are the guidelines for my operation

- I will learn and obey the rules of any contest I enter, including the rules of my entry category and obey the rules for amateur radio in my country.

- I will not modify my log after the contest by using additional data sources to correct callsign/exchange errors.

- I will accept the judging and scoring decisions of the contest sponsor as final.

- I will operate my transmitter with sufficient signal quality to minimize interference to others.

- I will listen, and listen, and then listen again before calling and only call if I can copy the DX station properly.

- 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 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 and/or when the DX operator queries a call sign not like mine.

- I will not transmit when the DX station requests geographic areas or callsign numbers other than mine.

- I will respect my fellow hams and conduct myself so as to earn their respect.
