PLEASE NOTE - As of September 2014, I have moved to Denmark and my new callsign is OZ5TN.


Hi there, and thanks for looking me up!

** IMPORTANT ** QSL for OV5T and AF7BE direct or via M0TRN - I am NOT a member of the Danish or US bureaux

My name's Thomas and my home QTH is Girton, about 3 miles north-west of the city centre of Cambridge, England. I'm originally from Denmark, but I have lived in Cambridge for the past 12 years. I'm 40 years old (as of 2014).

First licenced on 8 December 2010. I currently hold the following callsigns / licenses:

  • M0TRN - Primary call, UK Full Licence
  • OV5T - Full (Class A)Danish license (I'm a Danish citizen)
  • AF7BE - US Amateur Extra

These allow me to operate in much of the world, and I enjoy working hotel/mobile when I travel for work, which I do a fair bit. I tend to put my Danish call on the air when I visit relatives at home, and use the US call from Arizona and California when I travel there for work. If you worked me as AF7BE or OV5T chances are I was using my Elecraft KX3 at QRP levels, either from a hotel room or a hiking location, with an inverted V doublet suspended from whatever I could find.

My home station is the full Elecraft K-line lineup: Fully loaded K3, KPA500, KAT500, P3. I was using just the K3 with a valve(/tube) linear for several years. I love all the Elecraft products, and have built/assembled all of mine except for the K3 which I bought used as a reward after obtaining my full licence. I only use wire antennas, although I hope to one day gather the courage to apply for planning permission for a small mast.

CWis my great passion, and wanting to learn it was a major reason for getting into the hobby and getting licensed in the first place. I use a Begali Sculpture for most of my CW, but also have a beautiful straight key by G0NVT which I use for SKCC work (see below). Learning CW has been one of the most satisfying experiences. I currently can copy up to about 45-50 WPM and send reasonably clean code up to 30 WPM (I've practiced listening a lot more than sending).

I do enjoy a good contest, especially CW, but I can't always find the time to take part.

This was the brief version, feel free to read on for the (somewhat outdated) full version below.

QSL via bureau or direct. I am not very good at responding to these in a timely manner but hope to improve. Lucky I'm not a rare DX :)

Old news

27 Jul-8 Aug 2013:I was QRV (on and off, holiday style) as OV5T with my KX3 from Espergærde, Denmark, from 27 July to 8 August 2013.

02 Jan-09 Jan 2012:QRV asOV5Tfrom Copenhagen, Denmark on 2nd-9th January 2012, using FT-817ND with a long wire from Frederiksberg (part of Copenhagen city), grid square: JO65gq.

07 Jul-16 Jul 2011: I was QRV from Espergærde, Denmark as OV5T with my QRP station


I was first licenced on 8 December 2010 as M6TTH. On 1 March 2011 I passed the Intermediate exam and on 7 March I was licenced as 2E0ETT. I took the Advanced exam on 6 April and obtained my Full Licence and current callsign on April 28. I received my Danish callsign, OV5Ton 4 July 2011, and my US Extra license AF7BE in April 2013.

Operating out of my makeshift shack (my kitchen/dining room!), I use an Elecraft K3 with a valve linear, made by G3XNG, at up to about 350W. I am a big fanof CW and about 90% of my QSO's are in that mode, but also operate SSB and digital modes.
Current antennas (all homemade wire antennas, sadly no masts here):
  • 40m delta loop fed via 1:2.5 balun
  • 80m sloping dipole at 15m - 8m
  • 30m inverted V at about 12m
  • 20m inverted V at about 10m

Historical antennas:

  • 40m/30m/20m inverted V fan-dipole, secured about 15m up my eucalyptus tree (early 2011-late2012 when I replaced it with a bigger 5-band fan dipole that proved not to last very long due to its position)
  • A G7FEK antenna, which is my primary 80m antenna, and also used as a diversity rx antenna for the bands covered by the inv V's (late 2011-mid 2012when too many of the radials had been tangled in the lawnmower and I took it down)

Here's my old inverted V antenna:

My first ever QSO after being licenced was with Paul M0PNN on 11 December 2010. I wanted my first QSO to be on CW, and it worked out!I had been practicing CW for a couple of months. Learning the code is a very rewarding experience, when suddenly it starts coming together in your head at speeds in excess of 10 WPM, considering I didn't know much more Morse code than SOS just a couple of months earlier!

As of October 2012, I am now up to copying up to 35 WPM and and sending up to 30 WPM. I mostly use a Begali Sculpture, except for SKCC activities where my main straight key is a G0NVT PS213 key. For portable work I use the "built-in" paddles of my KX3 and I have a Czech army key, which I've found to be an extremely nice key to use.

At first I used the excellent open source Linux program Morse Classic to learn with (and also updated the program a fair bit in the process, resulting in the latest release). I learned by having the program transmit random letters at 25 WPM but with extra spacing inserted to bring the overall speed down to 7-10 words (and improving). That way you learn the sound of the letters at a higher speed, and it is easier to increase your copy speed. At least that's the theory, but listening on the bands is a lot harder than copying text on the PC. There is all kinds of QRM, every operator sends slightly different code, and nobody sends quite slowly enough for me to copy everything even when QRS'ing. But that's the challenge, and I'm getting better every day :) [ Written in early 2011, I've come a long way since then! ]

Other ham-related interests are SDR, digital modes and SWL. I have a (relatively neglected) blog here.

My portable QRP station until 2011, based on an FT-817ND (now replaced with KX3):

My QSL card:

Member of:

QSL INFO: If you send me a QSL card direct, I will send one back to you direct. No need for IRC's or green stamps. You paid for the postage to send yours, so I don't see why you should pay for the return postage as well! However, it might take a while for me to get round to processing these, so if you need it urgently please let me know or email me! Cards received via the bureau will be returned via the bureau as well.

I upload my log to Logbook Of The World (LOTW) on a regular basis, and once in a while I will upload to e-QSL as well, although I'm not a huge fan of that site.
