|May 6, 2006 Added a
page for the DI2BO medium wave experimentalstation operating on 440 kHz.
May 1, 2003
During the past few days I achieved quite
a loton LF, finally worked Sam, RN6BN and increased
my ODX to 2242 km. Sam was able to copy my Slow-HELL-Signal (thanks Markus
for providing the program!). After optimizing my Antenna matching circuit
I now have a loss resistance of only about 40 Ohms and can achieve antenna
currents of over 3 Amperes at an output of 350 Watt, leading to an ERPof
about 350 mW. This page now had 22.757 visitors since April 1999.I
thank each and every of them for their interest.
April 21, 2003
Re-erected my 18 m high umbrella antenna again
after a storm in October brought it down. Now, after six months absensefrom
the LF band new stations have arrived and I worked a few of them,for example
DL3JMM, SM1LCA, YU7AR, RU6LA and OK1DWF, I saw RN6BN in QRSS.With RU6LA I
reached my new QDX with 2113 km, working with an EMPR of onlyabout 150 mW
(!) because my antenna current is only 1.5 Amperes at themoment. UA6 is my
DXCC-country No. 21 on LF!
October 14, 2002
Edited some links, minor changes, mainly just
to show that I am still there!
March 30/31, 2002
An exciting weekend ... Ed, RU6LA and a crew
ofLF novices tried to operate from a location 2113 km away from here using
a 135m high antenna tower and the callsign RU6LWZ. They caused a lot ofattention
and a big pileup! Also saw YO2IS very weak in QRSS. Worked PA3CPMas a new
March 18, 2002
From Ko, NL9222 I bought a DSP56002EVM Modem andI am doing tests in PSK31 and PSK08 to check if this dedicated modem performs any better than a soundblaster. Worked Carl, DJ3QO as a new one. On March 4, 2002 I had a nice crossmode/crossband QSO withLaurie. G3AQC. He transmitted Jason on 71.800 kHz, I replied in plain CWon 136.500 kHz.
February 24, 2002
Worked Giulio, IK2DED yesterday in QRSS. I transmitted in DFCW. After finding out why my Hagenuk EX-1001 Exciter has some FM on the tranmissions I cured this and triedout several modes that are transmitted with an SSB transmitter. I had anice crossmode QSO with Fabian, DJ1YFK, he transmitted QRSS, I repliedin Slow-Hell, developed by DF6NM. I also had a crossmode QSO with Klaus,DN1VLF, and finally a HELL/HELL QSO in Slow HELL with Dave, G3YXM (another"first" I believe ...).
February 17, 2002
Worked Edgar, DL2HRE
yesterday as a new one. His 20 Watt signal was 339.
February 14, 2002
Ran a few tests in HELL mode, tried a QSO
qithG3YXM but the signal to noise ratio was too low. But Ko, NL9222, Wolf,
DL4YHF and Uwe, DJ8WX copied my signal.

After I managed to repair my PA again (yes,
guesswhat: it had blown up again last week during a transatlantic test ...
Iam running out of IRFP450s and have ordered 10 new ones ...) I checkedmy
station thouroughly today and made some nice contacts
.I worked both, Jim, M0BMU as well as Fabian, DJ1YFK for the first timein
January 12, 2002
Finally managed to contact Jeff, F6BWO

Changed the layout of my web-page to make
navigationa bit easier (... and it did cost a lot of sweat ... I am more
familiarin other things than HTML ...)
October 31, 2001 ("Halloween")
Worked Fabian, DJ1YFK in a crossmode QSO Slow-CW/Fast-CW
(Fabian with his 17 years is presumably the youngest LF amateur in Europe,
he is a CW High Speed enthusiast). Also got a reception report from Dieter,
DL4DSS from Southern Germany, more than 500 km away, through the "Convers"-mode
on the Packet Radio netweork. LF enthusiasts meet on channel 136!

Finally, after about 2 years of waiting, I
workedmy country #19, Finbar, EI0CF.
KeithRogers asked in my
guestbook,if I had some information on VLF and LF station transmitted
time signals,so I added an
externallink. Also worked OH1TN again.
October 7, 2001
Summer is over ... summer-vacation too ...
duringsummer vacation, my LF antenna came down due to a storm. Since that
timeI had a lot of qrl, but now I had time to repair my antenna and I am
March 25, 2001
Worked ON7ZO as a new-one.Participaed in the transatlantic test (without being heard or seen at theother side of the pond). I used my Hagenuk EX-2001 Exciter and injected an accurate audio frequency, only to realize that I produced the following signal that Uwe, DJ8WX recorded (the upper signal).
... it seems I need to work a little bit on mysignal stability ... although it is easy to recognize.
Rich, OM2TWvisited me. He operated as DL/OM2TW and we had some enjoyable time.

January 1, 2001
Last year was a successful and exciting year on LF, dozens of new
stationsworkedor heard, or my signal was
heardby them.The reception of several UK stations on 73 kHz led to succesful
crossbandQSOs. After receiving a special permit (one of five issued in DL)
for 1W ERP I further improved my power (now 150 mW EMRP, approx. 350 mW ERP).
I added various new modes to my transmitting capabilities
.First tests on 8900 - 9000 Hz were conducted (and the tests still willbe
continued as soon as weather permits ...). For the first time an LFsignal
from North America to Europe was identified.Yesterday
I conducted the first Slow-VoiceQSO on LF with
Markus, DF6NM, using compressed audio with a bandwidht of250 Hz. The counter
of this page (created April 2, 1999) climbed to 7357visitors today. And I
enjoyed the friendship and friendly assistance ofthe LF-community worldwide!
A happy new year to you all!
December 28, 2000
Added some information about the Hagenuk EX
1001SSB Exciter on the page describing my station setup
.My signal was heard by HA6PC and F6BWO, unfortunately
I could hear neither of them. HA6PC reported via the Packet Radio DX Cluster
that he will have more power in January. Continued to listen to VE1ZZsbeacon
tranmissions, however with less success than last time due to higherlocal
December 23, 2000
Did not have much time to update the pages, despitesome interesting happenings. Worked GI3KEV/p as a new one (first GI/DL?). Heard the GU-dxpedition ... and they saw my QRSS signal, but we did notmanage a QSO.
Got hold of a Hagenuk EX 1001 SSB Exciter thatdelivers 100 mW USB/LSB and A1A between 100 kHz and 30 MHz in 100 Hz steps.Got it running with a TDA2030 as buffer (2 to 4 Watts, thanks to OM2TW for the schematic) and ran my first DL/DL PSK31 QSO with DF0WD on 137.500 kHz.
Saw VE1ZZ's signal
tonighton 136.500 kHz. If the assumed locator (FN84CW) is correct, the distance
was 5278 km!
November 12, 2000
Haven't been qrv for a while due to some busniness
trips, a nice trip to Windsor to the RSGB HF/LF Conventions and a niceone-week
vacation in Cairo/SU. Beck home I found my station working fineand
worked LG6LG as a new country! Added and updatedsome
October 8, 2000
Ran a test in BPSK
yesterday and got reception report from several stations, ODX was fromAndy,
G4JNT (800 km). Worked DK6NI as a new one,was called
by DJ1ZB but Hajo's signal did not fully make it to ha a completeQSO. Change
to QRSS, Hajo!
September 30, 2000
Today we invented a new way of crossband QSOs. While being logged
intothe local dx-cluster I called cq on 136.690 kHz. Alan, G3NYK reported
mysignal to his cluster. Immediately Klaus, DK6AO used the 'chat' optionof
your cluster and gave me a reception report. Also Siggi, DC3AM connectedme
throguh packet radio and gave me a reprot. I answered in CW on LF andthe
first LF/dx-cluster qsos had been completed ... so if you hear me calling
cq with QSX DX-CLUSTER, just give me a call over there ... . Also finally
managed to work G3BDQ, not strong, but we madea
QSO. Also worked Mike, PA0CC as a new one.
September 23, 2000
Interesting Saturday ...
workedPetr, OK1FIG and his father Jiri, OK1ARN, both operating with a
150m highantenna tower. The produced the strongest signal I have ever heard
on LF.I QSPd some messages from the e-mail reflector to Petr and Jiri back
andforth, and they will try to cross the atlantic tonight. Also
workedWolf, DJ4WS for the first time. He also has got an excellent signal,
butstill some 20 dB weaker than the two OK stations, despite the fact he
isonly 180 km away and not 423 km.
September 20, 2000

September 3, 2000
Worked Rudi, DJ2EY
asa new one. Paul, G4MD saw my slow-CW cq-call this
morning and finally LWL Gamal managed to copy my signal
,Gamal is suffering from the bad QRM situation in the vicinity of several
large longwave stations near Frankfurt.

After Tom, G3OLB heard my signals a while ago we finally managed
tohave our first QSO (despite the heavy QRN tonight).
August 21, 2000
Nice LF weekend with good activity.
WorkedDF2BC/p from the lighthouse Campen as a new one (missed him during
hislast dx-pedition to the lighthouse). Also had a nice RTTY crossband
QSOin RTTY (50 bd, 170 Hz shift) with the fieldday station DL0PE/p on
theLuhberg in Peine with QSX on 144.575 MHz in FM. Did some promising tests
with earth electrodes on 8.9 kHz during this weekend with the help of Tom,

July 15, 2000
Attending the "1st German Ham Radio VLF Meeting" at Nürnberg,
well,Walter, DJ2LF, Markus, DF6NM and I had a nice beer together and exchanged
ideas. Came back with loads of new projects and plans. Added a new picture
to my index page.

July 7, 2000
Several people are listening to LF without having TX capabilities.
Igot some nice SWL or should I say LFL-cards. Added the SWL (LFL)-Callsigns
to my logbook.
July 1, 2000
After Walter, DJ2LF and Markus, DF6NM started with some very low frequency tests recently, three of us have asked theGerman RegTP for a special license to use the range between 8.9 to 9 kHzfor scientific studies. The licenses were granted recently, with a transmitteroutput of 20 Watt and the modulation bandwidth limited to 100 Hz. I amcurrently testing an old 20 Watt music PA with two EL84 and have ordered100 pieces ferrite bars and 300m Litz wire to achieve the necessary 1/2Henry (!) coil to get my 18m vertical LF antenna tuned up to the 35 kmwavelength! We do not expect much DX from this band, however, tests perfomedin the US on 3.5 kHz (see http://home.pon.net/785/EQUIP/transmit2.html )and in the UK by John, G0AKN ( http://www.wireless.freeserve.co.uk/)have revealed that a couple of miles can be reached ... we will keep youinformed. My personal goal for the beginning is to span 5 km ...
Probably it was never really understood for alot of fellow hams why Germany limits the output of LF transmitters to20 Watt. The main reason is the remote control application of the DCF39transmitter on 138.830 kHz. The German authorities feared that a higherpower would interfere with the small radio receivers that are build intostreet lights and other remote controlled devices. Continuous negotiationswith the German authorities, especially driven by Walter, DJ2LF, have reacheda first step towards a general application of a 1 W ERP rule. For a limitedperiod, five special licenses were issued (DJ2LF, DF6NM, DL1SAN, DF8ZRand DK8KW) to use 1 W ERP on LF. Probably more stations might be addedat a later stage. Main task of this test is to evaluate probable interferencebetween those other LF applications and the ham radio stations transmittingat high power. If no problems are being reported, we expect that 1 W ERPwill be generally allowed in Germany.

Installed a new counter today.
June 12, 2000
It's been a long time since I updated this
pagethe last time. The counter is gone, the Austrian Telecom had provided
itfree of charge but obviously decided to cancel that service without notice.
I will look for a new one (I had about 4300 visitors until today). Improved
my station a little bit, I will report about details later.
WorkedDJ7RDand DL0FTZ for the first time. Had a nice QSO with DF6NM,
Markus, who transmittedSlow-Hell.
WorkedLX1PD (country # 16).
May 14, 2000
Worked Wil, PA0BWL operating a station
froma windmill (it is windmill weekend in Holland!) under PI4OSS. Also managed
to work Markus, DF6NM for the first time in normal CW. CU next week inNürnberg,

April 23, 2000
Worked OK1DTN as a new one.
April 16, 2000
Worked the "Decca-Mast" dx-pedition (callsign
on 73 kHz: G3GRO) crossband in normal CW (71.800 / 137.250 kHz), as I believe
this was the first normal-CW crossband QSO G/DL. Thanks, guys for sharing
that experience with you!
April 15, 2000
Worked the "Decca-Mast" dx-pedition G3WSC
andmade some further field strength measurments. Changed "dBu" to "dBµV/m"
in my logbook, for details on how I calibratedmy
receiver/antenna system see here. Added a pagedescribing
a quick practical anaysisof the signal
strength advantage that Slow CW has compared to a normalCW signal (20
dB). Also added some further information to the field s
trengthmeasurements of DCF39 of last week.

April 13, 1973 I passed my German license exam and got the callsign
DK8KW. As time goes by ... . Added new information on
DCF39and the signal strength profile measurements
Gamaland I took on April 8, 2000. Also took a field strength
measurement of my own station and came to the conclusion that I onlyhave
30 mW ERP!

Worked Laurie, G3AQC
for the first time!
March 19, 2000
Worked Hellmuth, DF7VX as a new-one. Hellmuth
is the DARC VHF/UHF/SHF manager and he mentioned in our QSO that the signals
on LF sound very similar to EME!
March 12, 2000
Worked DL7YA as my
firstLF station from Berlin. Added some new links
. Boughta Siemens Selective Level Meter D2108. Nice receiver, but only limited
use for LF: one filter is 20 Hz wide (too small) and the next followingis
400 Hz (too wide). Receiption from 50 Hz to 30 MHz, so a nice unit toobservee
beacon stations on LF, MF and SW. Also got hold of a "Adret 2230A"frequency
synthesizer (0 Hz to 1 MHz in 1 Hz steps), output 20 dBm (100mW).
March 6, 2000
March 5, 2000
After Markus, DF6NM reported the successful recepteion of several
UKstations on the 73 kHz band, I got interested. Dave,
G3YXMand I today managed our first crossband QSO 73 kHz/136 kHz (826
km). Soonlater I worked Graham, G3XTZ in the same
manner(732 km). See Markus', DF6NM, well documented
observationson those historical QSOs. Added some information on the
GalvestonNDB (GLD) on 206 kHz, that I visited during my trip to the US.

Spend a nice afternoon with Hen, DF3OE in my shack (see picture). Weworked7S6SAJ as a new one. This was the strongest ham station ever heard on LF(41 dBµV/m!). Also worked G3LDO, Peter for the first time (heardhim many times!). Hen also made his first QSOs on LF (the LF bug caughthim, so I am sure soon we will have a new callsign on the air). We wentout to the field to do some calibrated field strengthmeasurments with a 1m solid loop.
Added some information on
DCF39(or DBF39 or DCF49 or however it calls itself ...). Currently working
onfurther measurements with my 1m diameter loop.Will
keep you posted. Added some information on the
receptionof DCF39 by stations in the United States.
January 22, 2000
Added some considerations to calibrate receiving
equipment to read field strength in dBµV/m
(thanks to Dick, PA0SE). Temporarily removed the search function (did not
work properly). I will look for an alternative. Added a couple of

After hearing the
SAQtransmissions on 17.200 kHz today with 559, I looked for more information
about stations below 100 kHz. I was able to copy the WX transmissions ofVTX3
on 18.200 kHz. ZL4ALI had distributed a listof stations
between 10 kHz and 100 kHz on
PacketRadio, which I added to my page..

Finally reached over 1000 km! Managed to work Reino, OH1TN. Additionally
worked Kai, OH3LYG with a QRB of 1317 km! Nighttime conditions seem tobe
good these days...
November 23, 1999
Updated my logbook
withthe QRB to GD0MRF: 987 km. Received e-mail from G0MRF: our QSO was the
first GD - DL QSO!
November 21, 1999
Another exciting and succesful weekend. Using the RF amlifier/preselector
of my Teletron LWF45 (2 x EF93 tubes!) to feed my MV62. I am not reallysure,
but I believe I was able to reduce out-of band QRM a couple of dB.At least
I can boost up signals by another 15 dB when there is low noiseon the band
(DCF39 with pre-amplifier: -9.4 dBu !). Worked the GD-dxpedition(GD0MRF,
GD3XTZ) with an excellent signal report on both sides. With IK5ZPVI worked
my first Italian station LF/LF (we had a crossband QSO LF/160mbefore). Valerio
and I had a crossmode QSO CW/Slow-CW (on 136.900, sorryfor any inconvenience).
Tried to work OH1TN, but the QSO was incompletebecause I was unable to copy
my report (Reino, we will give it anothertry!). Also completed my first normal
CW QSO with HB9ASB. Updated my logbookaccordingly.
November 14, 1999
Added G3LNP as a new-one worked to my log
October 31, 1999
Worked SM6PXJ, a new country for me! Today Wil, PA0BWL and I finally
manged a QSO. Yesterday I visited the INTERRADIO, in Hannover. I boughtanother
boat-ancor: A dedicated longwave receiver made by Teletron backin 1969, called
LWL45. It has two ranges, one between 40 and 80 and anotherone between 80
and 160 kHz. It was used some 30 years ago by the GermanWeather Service to
receive weather RTTY and FAX transmissions. It has abuild-in RTTY converter
with an oscilloscope. Dick, PA0SE, has some
moredetails (thanks, Dick, for the copy of the manual!).
October 24, 1999
The band is still good for new ones! After hearing Dave, MM0ALM
callingfor a couple of hours today, we finally managed a QSO. Also managed
tofinally be heard by OZ1KMR (see my logbook).
October 17, 1999
Added OZ8NJ as a new-one to my logbook.
October 14, 1999
In Windsor I presented some signal strength
observationsthat I mad during my QSOs and during listening into the band.
Here youfind the graph that show the difficult
situationof (most) DL stations operating with 20 Watts.

October 10, 1999
Just returned from the RSGB HF Convention in Old Windsor near London.
It was a wondeful experience to meet all those nice people behind all the
callsigns you hear (or see) on LF or read on the reflector. Half of my
logbookwas present and in the future they will surely re-name it to RSGB
LF Convention(with some HF people also attending ...). After my return my
XYL Andrea(DL3ABC) and I erected my telescopic antenna
under severe weather conditions in high winds (it took us nearly an hour)
and had a Slow-CW QSO with the guys back at Old Windsor (GB4RS). Also worked
Petr, OK1FIG for the first time in Slow-CW.
September 26, 1999
Worked DF6NM as a
newone in Slow-CW. Had another normal CW QSO with Petr, OK1FIG, now again
a couple of dB stronger than last time. Mike, G3XDV improved his antennaand
we had another 'o'/'o' Slow-CW QSO.
September 20, 1999
Another nice weekend with a couple of new
QSOson Sunday (I was busy on Saturday, our folk-mucis group
Piper'sWine had a public appearance). Logged
PA2NJNand DJ1RL as new ones. Signals seemed to be a couple of dB down compared
to other weekends. Noise also was low.
September 12, 1999
A nice weekend: weather was fine and the LF
bandfull of new stations. Worked two new countries,
OK1FIG and OZ5N, and two more new stations, DK1IS and DK9DX. CorrectedDJ6FU's
callsign in my electronic logbook, itwas ok in my
paper log (yes, I still do have that!). Got an e-mail fromHeinz, OE5EEG/5,
who heard me and called me in vain ...
September 11, 1999
September 9, 1999
Added DJ7RD and GW3XDV/p in my log, both
heardmy CW signal, Mike from a distance of 1029 km (new ODX for someone hearing
September 5, 1999
I made a 1 hour PSK31
testtransmission today on 137.450 kHz and got a reception report from DJ2LF,
309 km away. He could even copy my signal with a 20 dB attenuator switched
on. The transmitting system seems to work fine.
September 4, 1999
Added G4GVC and G3KEV to the list of
newones worked. After we had a crossband QSO 2200m/80m in January
and a Slow CW QSO in July I had a nice normal CW QSO with Dave,
G3YXM.Worked on my SSB-LF station and started
to runa couple of test transmissions in
PSK31on 137.450 kHz.
September 2, 1999
Added a definition of dBu that I found in
theInternet. The unit dBu is used in audio and RF engineering
and that is the unit that my MV61 and MV62 selective
level meters give as signal strength (by definition: 0 dBu=0.775 V, dBuis
not to be mixed up with dB mico-volt, the letter "u" in this case standsfor
"unterminated"). Added a few links on the eclipse-observation
page and Vaino's (OH2LX) DCF39 field strength observation
September 1, 1999
I have been to EI with my family during the past 14 days. Had a
DatongLF converter and a Sony ICF-SW100 plus a couple of feet of antenna
wirein my luggage so I was able to tune into the band from time to time.
Iwas unable to copy any amateur signals and only could hear DCF39 very weak,
however, I am certain that I operated the first LF listening post froma horse
drawn caravan! Added OK1FIG
and G4GVC to the list of stations that heard meand
two spectrograms of my Slow CW signal recordedby
August 16, 1999
Added a link the page of
Andreas,DL2KCL. Got hold of an MV62, the successor of the
MV61selective level meter. Currently I am testing this new device that
hasa digital frequency and signal strength readout. Seems to work well as
August 14, 1999
Added some new stations heard, worked DL3FDO
as a new one. Added one more GBR-Sunrise graph. Added
some graphs of Vaino, OH2LX's field strength measurments
August 11, 1999
After a beautiful optical view on the eclipse today (about 88% here
in Peine) I came back home and had a look on the field
strength measurement of HBG75 on 75 kHz. Why are ther two maxima?
August 10, 1999
Indeed, it works. The strength
anomaly of GBR at sunrise can clearly be seen!
August 9, 1999
Added a page with field
strengthmeasurements of GBR at sunrise. This measurement was initiated
by Jean-Jacques,ON5PG for scientific purposes. On Sunday, OE5EEG
heardmy CW signal but could not answer me because their transmitter was
down. Added a new cartoon on my index page (following
a real experience of Wolf, DF2PY).
August 8, 1999
Well, finally decided to pull out my fibre-glas telescopic mast
to thefull18m. Installed a second set of nylon
guy wires. Had a couple of niceQSOstoday, added
a spectrogram of DJ2LF and PA0MLCas a new one on
my stations heard or worked page.Tried to receive
transmissions, without success.

GW4ALG,heard my signal last weekend, we had a succesful
QSOtoday in normal CW. Also worked DJ5DI as a new one. Shortened my 4
top-loadradials of my umbrella antenna and improved
DCF39reception by another

Added alist of LF utility stations, that
canbe used as propagation indicators (thanks to Marco, IK1ODO). Re-organized
the main index page. Added a link to the
links-page.Changed the cartoon on the main indes

By e-mail, I got a nice report from Steve,
GW4ALG.He had heard my QSOs yesterday with ON7YD and DJ2LF. He clearly
could readmy signal. This is the new ODX of a station hearing me (880 km).
So far,my new antenna setup doubled my reach. Well, after a nice CW QSO with
Graham,G3XTZ, this morning, I have to say it nearly quadrupled my reach!
Grahamis 732 km away! Also finally had a QSO with Wolf,

What a day! Hopefully I am not the new crocodile in town now. Called
cq in normal CW with my new antenna setup and was first called by ON7YDand
then by DJ2LF. While the QSO with Rik (my new CW ODX!) was relativelypainless,
Walter, DJ2LF, needed a lot patience until I finally was ableto copy his
callsign and my report through the noise, while he could copyme with readability
5! Ha-Jo, DJ1ZB, send me an e-mail telling me thathe called me also, but
I could not copy him at all. Also could log PA0LEG(my first PA!) and PA0SE.
My logbook is fillingup!

Currently I am experimenting with my umbrella-antena
.I have re-positioned and shortened the radials a bit and thereby reduced
overall losses. The reception of DFC39 has improved
now from previously -46 dB(75) with the previousMarconi
T-antenna down to -29 dB(75), eqiuvalentto
S9+54 dB (S9=100 uV).

Finally I got my new fibre-glas vertical
antennasystem for LF set up (15 to 18m high, depending on wind conditions).
With this antenna system just tuned-up, I called cq in
Slow-CWand received an answer by
Mike, G3XDV.My first 2-way contact

I recorded the backgound noise
over 24 hours at my QTH to find out about the best operating time (forthose
of you who like to sleep long: sorry, best time for me is 04.00 UTC!).

Well, today I was able to spot Mike, G3XDV's signal (see
hisSpectrogramhere). No 2-way QSO
yet but we will try again! Also ON4ZK can be seen onthe same
Spectrogram. Re-arrangedthe Spectrogram-page
alittlebit. Still trying to find out the best parameters for Spectrogram

Mike, G3XDV was able to copy my very weak Slow-CW signal 707 km
away,which is a new ODX for me (updated the
