Hi folks,
Thanks for looking up my bio on qrz.com  !

I've passed the ham radio exam in May 1970
on a day between two highschool exams.
You bet, I valued my ticket DK3XT more
than my high school diploma ...
I've made my first steps on VHF/2m working with
a homemade crystal-controlled fixed frequency
AM transmitter of 8watts and a pair of vertically
stacked 2ele HB9CV type antennas. Working a distance
of 30km I called "DX" in those days.

Moved on to a qth in Hamburg/Northern Germany,
set up 2x13ele 3wl DJ9BV antennas, Icom IC201
and a PA of 80watts output.

In the years 1976-1982 I ran about 150 meteorscatter qsos
in high speed cw from a UHER 4-speed taperecorder
and a homemade memory keyer.
QSOs in MS usually ran 2hours, 5min periods, max 600lpm.
Skeds were arranged, sometimes weeks in advance, by snail mail
or via VHFnet on HF 14.345MHz.

My best lucky shot in meteorscatter marks a qso with an
Iceland dxpedition of GM3YOR/TF in August 1978,
which gave us the honor of having completed the
1st ever recorded qso on VHF between Iceland and WestGermany.

I left Hamburg in the 1980s, various jobs and projects
of research and development in the field of nuclear energy
took me to places in southern Germany.

With a VE-team on Bitburg AirForce Base in Germany in May 1995,
I got my US ticket as AB7IY (Extra Class) after having
been licensed as KC7CZY (Technician) before.
In those days, key requirement for the Extra Class
was passing a morse code exam with 100lpm (20wpm).

As AB7IY, I extensively travelled the USA, so far,
visited 24 of the 50 states. My heart, though,
will always belong to the down-to-earth people and
my beloved friends in Roy/Montana/Fergus County,
in the middle of nowhere, where Montana is, what America was.

From 1996 - 2006, I was owner and webmaster of "meteorscatter.net" .

After being qrv every now and then, I went back on the air
from JN49fe on Sept 1st, 2013 with a qso in FSK441 with OM5CM .

My current rig consists of a single 3wl yagi YU7EF, lna HA8ET and
high power coaxial relay in a box attached to the antenna pole.
Split rx/tx lowloss coax lines run to an SSPA Beko HLV1000 and
a US-specs FT736R.
The rx line connects directly to the 1st rx stage of the FT736R.
Rx/Tx switching is done in the antenna box, controlled by a sequencer.
The antenna box sits right below the roof, coaxial relay and lna are
air-cooled by fan. Rotor is a KENPRO KR-5600A, Az/El controlled by
ERC-M interface with digital readout and YO3DMU's PstRotator with moontracker.
The audio signal is picked up from the FT736R's data output, processed
through a digital DSP filter by Sotabeams, thus producing a nice flat
passband curve 100hz-2900hz, then fed into the computer.

I'm in (slow) process of setting up a 10/11ele crossyagi, a high quality
prototype design (GTV 2-9n XPOL QRO) by DG7YBN, featuring angled dipoles,
current baluns of LCF-1250 coax with 7/16'' spinner connectors
and switchable H/V planes.

My radio programs are running on a mil-spec Panasonic CF-30 toughbook.

Standings & Grid Counts since Sept 1st,2013 :

All of the following qsos were made with single yagi HPol / 750W .

As of Feb 19th,2018 I've worked 487 worldwide qth-locators, 68 DXCCs
via MS, EME, Tropo, Es & Aurora.

Since Feb 22nd,2015, I've worked 612 qsos, 188 inits, 6 continents,
46 DXCCs, 22 US-states, 41 US-inits via EME.

On June 30th,2015 I expanded my terrestial VHF ODX to 3148km in a qso
with EA8TX/Canary Islands/IL18qi, in a mix of MS into Atlantic Tropo.
We completed the qso in 28 minutes.

On July 17th,2015 I've worked EA8TX once again, this time in SSB
via Es propagation.
We completed the qso in 30 seconds.

On Aug 30th,2015 I've worked TF3CY via EME, almost to the day 37 years
after my 1st contact DL-TF with GM3YOR/TF.

On Oct 7th,2015 I've worked ZL2ADU via EME, setting my ODX to 18434km.

On Oct 27th,2015 I've worked TO2EME via EME, first time I've managed
to work an EME-dxpedition. After about 4 days of listening
to an ever growing pile-up, everything fell into place :
excellent operators, early morning moonset, very low degrad,
very quiet band, no man made noise, no pile-up, I clearly picked up
their "CQ", and my single yagi weak signal finally made it through.

On Nov 13th,2016 I've worked the 100th MS-qso with Lyn, GW8JLY.
On Aug 22nd,2017 I've worked the  50th MS-qso with Stamen, LZ1KU.
On Nov 25th,2017 I've worked the 100th MS-qso with Tage, SM7NMO.
On Dec 16th,2017 I've worked the 150th MS-qso with Peter, LZ2PG.
On Dec 31st,2017 I've worked the 200th MS-qso with Plamen, LZ2PI.
On Feb 17th,2018 I've worked the 150th MS-qso with Tseko, LZ2FO.

Above the most extraordinary birthday card I've ever received.
Tnx Tage, SM7NMO !

Looking forward to meet you on VHF/2m :

73, Bernie DK3XT/AB7IY
