12.Jan.2011: report from
DL2HRE when G3KEV and i calling CQ
On 23.04.2009 i have my new linear transverter ready which allows me to run all digital modes on LF/MF. Here nice report of my WSPR beacon with some details about the transverter:

QSO with DL2HRE! Sked with Edgar, copied “0”. Capture of
our QSO:
and what a fun after the QSO Jeff,
F6BWO called me for my 3rd QSO:
·
30.Jan.09 16:30-17:06UTC –my 1st
QSO with DF6NM! i had a sked with Markus and he copied
my “0”. Capture of our QSO:
DF6NM in DFCW3 and I in QRSS3; Markus calculated my ERP to 1.8mW
(Dein Signal war ca. 1 µV/m hier. Tagsüber sollte das sogar gerade hörbar
sein, aber im abendlichen Störpegel konnte ich mit dem Ohr nichts wahrnehmen.
Mit der Entfernung (ca. 200 km?) und der Bodenwellendämpfung lässt sich Deine
Strahlungsleistung schätzen:
EMRP /dBm = E / dBuV/m -50 + 20 log (r/km) + 0.02 * r/km = 0 - 50 + 46 +
4 = 0
also ca 0 dBm = 1 mW abgestrahlte Leistung oder 1.8 mW ERP bezogen auf einen
Halbwellendipol)

28.Jan.09 Test transmission on 137.7798
in QRSS60: Henny,
PA3CPM sent me this snapshot:
·
26.Jan.09 permanent QRV on 137KHz: i installed my 34m longwire a bit higher with a 8m vertical part.
Matching between loading coil and transmitter is still not good and I loss a
lot power. However signal is now strong enough to see my QRSS3 signal in the
grabber of DL2HRE and DF6NM:
·
14.+15.Nov. 2008 – 3rd time on 137KHz: unfortunately high QRN level, I tested with Markus, DF6NM and he
received my signal with ~0.6-0.8mV. Good enough for QRSS3 when QRN is low. Fine signal from him in
DFCW:
(on top my signal, sri I sent MN instead NM! DF6NM in DFCW calling
me)
·
13.+14.Oct. 2008 – 2nd time
I transmit on 137KHz: result was very mixed. First I killed
my 250W amplifier again due some oscillations. Monday morning I tx then just
with the driver and 5W. Very impressive to saw my QRSS60 signal just with this
low power in the DF6MN grabber! In the evening I used my backup PA with
~50-60W. A sked with DL1EIE was not successful, but I could see my QRSS3 signal
weak in the grabber of DL2HRE. However this evening my QRSS60 signal was not
that strong in grabber of DF6MN and DL2HRE as I hoped before. On Tuesday
morning I had a sked with Gerhard, DK6NI -> I had a ufb copy of his QRSS3
signal and he was able to copy me in QRSS10 just on a small active antenna :-)
my QRSS10 signal copied by DK6NI
·
10.May 2008 I did my 1st
test (beacon) transmission in QRSS30/60 on 137.776KHz (setup was very experimental, see details under “my station”). I was very
impressed about following successful reports of my longwave signal! [My special thanks to Gerhard, DK6NI and Arnim, DL1EIE for all
their help and support and to Heinz, DM2BHG for many used LF parts of my
station!]

March 2007 i solder
my "LF Exciter" - which is a state-of-the-art unit (transmitter)
especially for LF enthusiasts and "Lowfers". With very good stability
and 1W sinewave output, the unit can be used as a low power transmitter, signal
generator, or to drive high powered transmitters. Modes are Morse & ASK
incl. QRSS, ASK image like Feld-Hell, FSK, DFSK (DFCW), MFSK (MT-Hell), MFSK or
IFK data like Jason. Operating range 0.08 - >400 KHz. I purchased from DF1CY
the "LF exciter" board and programmed microcontroller. The rest was
soldered in a couple of hours.
Here some snapshots where i
transmit on 137.7 KHz:
1st: LF Exciter in beacon mode -
2nd: my call in QRSS3
