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

This is the Contest and DX call for SA3BYC  Johan or in English John.  I'm located in Åre, a skiresort, 700 km north of countrys capitol Stockholm and only appr. 60 km east of the Norwegian border. On the mountain side, 520 m above sea level, 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, then the very strong winds and ice build-up on my antennas in the winter. I have to limit antenna mast height and prefer that to have my antennas low and always in the air - instead of on the ground after one of our frequent winter storms.

QSL info:  I'm not a collector of paper QSL cards and strongly encourage everyone to start using modern electronic QSL systems instead. Please stop sending me Qsl cards I haven't asked for! I'm not a member of the bureau and cards received to Sweden will be returned and not delivered to me.

All my contacts will be confirmed and uploaded to e-Qsl, LoTW , HRD log and Club log on a regular basis.  If you are a paper-chaser I will only send paper QSL direct, Pse e-mail me for information! I just  received the new postalrates and a direct card will from january 2015 cost 2,50 Euro (expensive? well, it barely cover my cost).

Last Qso's from my main log (Thnx to HRD and HRD logg)

My LOTW statistics (confirmed/worked):   All band DXCC: 128/163.  5 band DXCC: 42/66/76/87/83.   WARC band (12, 17m) DXCC: 17/45.   All band WAS: 38/50,  All band WPX: 971    All band Challenge: 416 

SE3X Set-Up

Kenwood TS-590S, PA Amp Supply LK-450 (3-500Z), LDG-1000 ATU, MFJ-826B digital SWR meter connected via a SPID 8-port antenna switch to my antennas.  microHAM USB-III cat/audio Interface for RTTY, Voice Keyer, CW and other digital modes. PC's for logging, digital modes, etc. I have the PC's connected in a schack WLAN with a common back-up harddrive, Internet via mobile connection, no fixed Internet out here,  router and firewall. Software used: N1MM, Log4U for contest, HRD as mainlogg, DX-Atlas etc. Win XP and Win 8 as OS.


Mast 1; wire-antennas: 80/40m dipole on topp @ 12m, 40/15m wire-vertical and 20m wire-vertical both with elevated radials @ 10m. 

Mast 2;  3 element, tribander short boom Yagi for 10, 15, 20m @ 10m.

Receive: 80,5m RX loop, horizontal, @ 3m agl.











2015 "SE3X - to do" list"

Station:  Re-build PA (LK-450) for lower noice and add 2'nd fan for long contest runs. microHAM USB-III Interface for RTTY and digitalmodes. New switchbox with PRE-amp for RX antennas, KD9SV DXSS DXpedition Receive Antenna Switch. Add 25 A, 13,5 V,  PS for redundancy (today single point of failure).  CW keyer / Bencher BY-1. microHAM u2R, SO2R, Station Controller.

Longterm goal is to add a second radio, don't know which, building limited SO2R capacity.  I'm quite happy running SO2V, but 2 radios and simple switching would be nice to have. As well I don't like having the one radio as a single point of failure, any problem with Trx ...  that's it! QRT!

TX antennas:  Add 80m L-vertical with elevated radials for DX and contest outside EU.

Add 10m Inv-V or Slooper dipole, mast 1,  to have full wireantenna coverage for 10-80m EU contesting.

Like to add 160m capacity, probably going for a shortened 10-160m OCF, homebrew or commercial from RadioWavz.  Reason for the OCF is to have an antenna that could be separated from the antenna switch, by the flip of a manual switch, and used for Trx 2 when running "limited" SO2R instead of SO2V in the future.

Getting 6m and WARC 12m / 17m in my antennasystem when changing my 3-band, 3-element mini-beam to 6-band Hexbeam (SP7IDX) 6/10/12/15/17/20m with a new SPID RAU rotator.

RX antennas: 2 new RX antennas summer 2015. Directional East/West and North/South. RX antennas to be switched together with my RX-loop via a switchbox.  Goal is to improve RX antenna efficiency, if you don't hear them - you won't work e'm!  The following picture illustrates the finished TX / RX antenna set-up and the switching logic. Goal is to have the changes in place for winter 2015/2016 radio season.

Having a good idéa what works, and not, at my Qth I plan some changes to my set-up during 2015. This is a drawing on how the Antenna set-up will look after installation of new antennas and new  switching devices.

Focus this coming summer will be to improve RX antennas with two new directional antennas and KD9SV pre-amp switch. Changing the 3-el beam för a 6-band Hex and adding a 80m vertical, will improve my DX signals a lot. I will start preparing for a second TRx by adding a 10-160m OCF. A manual switch will make it possibel to either let it be connected to the main switch and TRx 1, or to a second radio. My RX loop, 80.5m long with a 4:1 balun works very well for NVIS contacts on 10-80m. A manual switch will make it possibel to either let it be connected to the main switch as TX loop or to the RX switch as one of my RX antennas.

Rebuilding, adding useful equipment and improving my station and my antennas during 2015. This picture describes my vision on where I will be in the future.

I still don't know when I can afford a second radio, and absolutely not sure what it gonna be. One of my options is of course a second TS-590, another a Yeasu FT-2000, which will demand a lot of modification for contesting (AC0C mods), or maybe it will be something totaly different?

By the way, Thank you for reading all the way down on my Qrz.com page :) Hope to meet you on the radio, or if you are here because we just made a contact, Thanx. Anyway,  have fun and enjoy the hobby!


Op. Johan
