Thanks to mother nature, only one of the
original 2 100 metre wires of this aerial remains in the air.
January 2005: Mother nature takes remaining wire... and the 25 metre tower!
February 2005: 100 metres of wire at 10 metres average height.
December 2010: 100m at 15 m average height. |

December: 1200 Watts 4.5 Amps RF to a 100m wire up 15 metres.
1st: M0BMU reported another daytime reception.
Propagation expert G3NYK writes in response to Jim :
"a low level geomagnetic event pushed the Dst index down a bit on the
30th and the 1st. At this time of year this could give a significant
increase in the daytime ionisation in the D-region. I have seen very
noticable effects on shorter daytime paths immediately after a major
geomagnetic event, and I have seen some variations that seemed in time with
Dst values on the path to Lakihegy HGA22. My other thought is that the
daytime D-layer could be weaker at this time of year and not absorbing so
strongly so the signals could reach the E-region. However it seems unlikely
that the returning signal would be strong enough to detect." Thank Alan.
The TX was shut off at 1101 UTC which was the time of
last reception at M0BMU.
4th: Reports from F1AFJ (a big pile up in the TA watering hole:
WD2XES, WD2XNS, WD2XGJ, WD2XKO, VO1NA) and PA3CPM.
6th: a brief transmission between ~2100 and 2400 was copied by
DK7KC, G3WCB and RW3AGC. Signals were then received from DK7FC and PA3CPM
using the FT817, tower and National LF10 preselector.
8 December: 2320 UTC Aural reception of DK7FC at 4400 km.
Audio: clip 1 and
clip 2 at 2358 UTC.
This is the first TA aural reception of an
amateur LF signal at this station. Coincidence: first aural reception
of this station was in Germany (H. Wolff).
DFCW transmissions (4.5 amps 1200W) on 137.777 were received
by PA3CPM,PA3FNY and DL7ET. 10: RN3AGC and G3WCB reported.
11-14 Dec. Called CW DFCW10 and with considerable incompetence
ran DFCW60 before reducing the FSK. Ran CW for local reception
experiments. Reports gratefully acknowledged from RN3AGC G3WCB and VO1SQ.
14: Reports from RN3ACG PA3FN and VA7JX. The reception by VA7JX
is believed to be the first transcontinental transmission of an
amateur long wave signal.
27: Another TA QSO with DK7FC. Stefan was using QRSS3 to yield
O copy and audible signals. Below is a partial transcript of Stefan's
signals. Receiver: FT-817/LF-10 preselector and 100m wire resonated
with 1.6 mH. 30: Stefan had some TX trouble but a tone was heard
on 136.17 kHz: a glance of the ARGO screen showed it to be Jim M0MBU.
This is the first audible 2200m reception from the UK.
Stefan copied this from across the pond:
Following the ensuing festivities, the VE3OT Beacon
MP was seen on 137.78 kHz. 
.
30: Audible signals heard from M0BMU, the second station to be heard
from across the pond. Also, 6 complete frames of OPERA(a digital mode) were
received on 137.38 kHz from G4WGT with thanks also to G0NBD. 31: TA signals received from PA3CPM PA3FNY PA0A
DK7FC DK6NM M0BMU and G3KEV: ARGO Screen around
136.17 kHz.
November
1 1kw 4.5 amps. Reports: PA3FNY PA3CPM F1AFJ.
2 Copied WE2XEB on 184.51 kHz. FT817/Burhans preamp(35dB) and tower.
20 Nov. TX on again. 4.5 Amps to 100m wire at 15m. Reports from PA3CPM, RN3AFC F1AFJ and DF6NM 21: PA3CPMi, F1AFJ, RN3AGC and F-60130 reported strong sigs.
22: Strong sigs received by M0BMU using a 30 cm ferrite rod antenna.
25: Copied by PA3CPM and an interesting reception by M0BMU at 1120 UTC over
a full daylight path. The abrupt disappearance of the sigs corresponds
to the TX being switched off at 1121 utc, a half hour after local sunrise.
Local sunrise time 1051 UTC, at M0BMU 0740 UTC.
26: Reports from MOBMU PA3CPM PA3FNY and 4X1RF.
27: Reports from DF6NM 4X1RF PA3FNY F1AFJ and G3WCB. 28,

Signal reports from RN3AGC and RN3AUS
(Moscow) 4X1RF (reporting on reception in Bucharest and 4X) F1AFJ and
PA3CPM are gratefully acknowledged. 
Reception
by 4X1RF at a distance of 7227 km.
20: 100 watts to 100m wire 15 m. Reports from PA3FNY PA3CPM F1AFJ W1VD.
21: reports from PA3CPM and PA3FNY. 22 1 kw to tower resulted in a fried
relay
but once this was removed, reports
were received from 4X1RF F1AFJ F4DTL and PA3CPM. The fried relay
has become a celebrity: please see page 58 of the December 2011 RadCom.
It is also a testament to the brute force of a Decca amp!
23 Oct. Interesting mid-afternoon reception by W1VD over a daylight
path.
Thanks Jay. Overnight copies
were seen on the F1AFJ grabber with evidence of much variability in
the propation and reports were gratefully received from PA3CPM and PA3FNY.

Operation Schedule / Signal Reports 2007
December: A report is being drafted for RAC/IC concerning experimentation
on the 135.7-137.8 kHz band. Submissions from those granted special
authorisations are welcomed. 16 December: F1AFJ reported weak traces
just after 0100 and 0115 utc, the second looking much line an 'N'.
These were likely signals from here. Good work JP.
November. 189.9498 kHz dot 180 synchronised to UTC. 1-2 Nil at
F1AFJ. Good news from WRC07 concerning a possible new 2200m band!
03-05 Nil at F1AFJ. 7th: 2200m proposal passed by WRC Committee 4 this
morning but still no trace of sigs at F1AFJ. 8: Nil At F1AFJ
9th Nil at F1AFJ. WRC07 APPROVES A 2200m BAND! 10-11 Nil at F1AFJ.
12-15 Still no sigs seen at F1AFJ despite lower noise levels.
20th was off air for a few days, but back on again today, but still no reported
receptions. F1AFJ reported no sigs on 21st but a weak trace at 0600utc on the
22nd. nil on 23rd. Beacon off 28 Nov 2007. Many thanks to Jean-Pierre
and Hartmut for their reports.
October: 5th 187.37 kHz. 10 watts to 100m wire at 10m. Tuned with 0.9 mH.
The transmitter and keying includes a DDS
synthesiser and class E PA stage. A CMOS 4020 handles the wavelength
multiplication (X16) from 100 to 1600m and the carrier keying. 9th: copied by
W1TAG at 0913 UTC. Nil at F1AFJ. Keying speed: QRSS240. 10,11,12: Nil at F1AFJ.
13: Nil at F1AFJ; faint traces on 187.3703 kHz reported by H. Wolff. 13: On
again at 1800 utc using tcxo as reference oscillator; f=c/1600=187.3702(8625)
kHz (+-0.1 Hz). 14: W1TAG sends a shot showing improved stability but a
frequency error of 140 mHz. 
The DDS was scaled back to
correct the frequency. F1AFJ monitored but has not yet detected the signals.
15: Detected in France? Jean-Pierre F1AFJ sends a capture (0510 UTC) showing
a trace in the right place. 
Hartmut confirms the
frequency shift was close: 187.37025 kHz +- 0.05 Hz and that the QRI had been
greatly reduced. 16-17: Nil at F1AFJ. 16th confirmed fragments received in
Germany by Hartmut Wolff but nil on 17th. 18th: Hartmut copies sigs again.

Now using Colpitts osc which is more stable, but still drifts a bit.
7 March 2005. 189.81 kHz +/- 1 Hz and the usual QRH, QRSS~120.
24 Feb. Jim Dean of RAC endorses the proposals for continuing
the experiments which included some helpful suggestions from Ken
Pulfer. The Industry Canada LOA was requested for one year starting
1 March 2005. In the mean time, experiments are being conducted on
1600 metres (189.81 kHz) under a different LOA from Industry Canada.
TX: 5 watts output, 0.4 amps to a 100 metre wire.
Reception reports have been received from K2ORS and W1TAG in MA and
W1VD in CT. Despite the very high QRM from commercial broadcasting
in EU, Hartmut Wolff has also received the signals. This is believed to
be the first transatlantic LF QRP signal and the first transatlantic
1600 metre signal (160-190 kHz band). More information is
available here.
20 Feb. Dot 30 1.6 A 90 Watts. Good copy at G3NYK and H.Wolff

Hartmut managed to get a good copy before his sunrise. 11: T less than 0C and
aerial current up to 1.45 A. QRSS30 copied by HW. and G3NYK.
12: Good at HW and at G3NYK. Alan has predicted improved conditions
and on the 13th the signals were copied at good strength at G3NYK and
by HW. Traces at CT1DRP. Hartmut had a copy in QRSS3 mode. Mother Nature is
evidently quite irritated with what appears to be a restoration of regular TA
receptions in spite of her short lived success in putting the station
off the air on 24 Jan... She has iced my 100 metre aerial wire and it
might not survive today as the freezing drizzle storm continues.
6 Feb. Good copy from SM6BHZ and traces of 2-3 others.
5 Feb. Temp > 0 deg and aerial current is very low. No transmissions
today. Sorry. Fair to good reception here of YU7AR.

warm WX until Monday, 24th. Blizzard tomorrow.
20 Jan. TX off as a result of malfunction, possibly due to WX.
2040UTC: inspected feedpoint. Considerable ice encrustation of
tuning apparatus and the entire length of the wire aerial which is now
about 1 cm thicker due to ice which is likely detuning the aerial.
Will wait and hope wire stays up until the ice melts.
18 Jan. Back on Diode Matrix ID at approx. QRSS30. Power output varies

6 August.
Thanks to a new FET and fuses, the TX is now operational.
It is hoped that the beacon will be QRV again following more ATU work.
18-25 July 100 watts 137.777 kHz 24 hours/day, dot 30 and 5 WPM.
A different aerial/ATU arrangement is being used. The ATU is now at
the near end of the wire. Aerial tuning was less than optimal and after a few
days on the air the FET became fried. This FET had provided over a year of
fine service despite the high duty cycle and several episodes of abuse during
aerial matching exercises.
20 July good copy at W1TAG of QRSS30. Best reception at 0600-0630.
21: Good reception by H. Wolf.

Timeline and signal reports:
Please note that signal reports and frequency measurements
are appreciated.
2003
Jan-Feb 2003 -- An experimental proposal is developed in consultation with
officials of Radio Amateurs of Canada and submitted to Industry Canada. MRCN
members copy transatlantic commercial and amateur signals on 2200 metres.
The first amateur radio signals received from Europe were from Brian CT1DRP.
March -- Experimental authorisation granted by Industry Canada for CW and FSK
emissions on a secondary basis. A 5 watt transmitter used for long wave experiments
in 1992 was retuned for 136.269 kHz and coupled to a 30 metre wire aerial. Signals
were heard 7 km away. A 15 watt class E tx is designed (per details at G3NYK) and built
using a p-channel MOSFET.
Cross band contacts were had with several MRCN members including VO1FB,VO1HP
and VO1XP. The carrier was generated by a 13.583 MHz crystal in
a Canadian Marconi XH100 receiver OCXO and digitally divided by 100 to give
a carrier frequency of 135.830 kHz.
A 150 metre wire aerial was deployed and signals are detected by W1TAG in Mass. about 1600 km away.
April W1TAG positively identifies signals. Transatlantic tests commence.
A 125 watt class E tx is designed and constructed.
May -- MRCN Bridges the Atlantic on LF!
G3NYK detects and identifies the signals. They are also copied by W1VD,W3EEE,
M0BMU and CT1DRP. Signals are detected by VE3OT whose own transmissions were
copied by MRCN earlier.
12 June Following exchanges of the spectra between M0BMU and VO1NA, it was determined that callsigns and signal reports were successfully transmitted and received
at each station. The first LF transatlantic QSO from Newfoundland is now
recorded. See the archives of the
G3YXM LF news site for 12 June to see the spectra of the QSO.
A 125 watt transmitter was used at this end. M0BMU ran 1200 watts.

Listening (watching) for Long Wave signals.
You will need a program
called Argo by I2PHD and IK2CZL.
Argo is an advanced FFT spectrum analysis package that will make it possible to detect and copy
signals that may not be audible in the high noise.
There is a well written primer on how FFT works and bandwidth/information
theory in very simple terms at this site.
Another excellent product is Spectrum Lab.
For receiving, a piece of wire is not especially useful for weak signals
on LF unless it is carefully tuned. Without tuning, it has an enormous Xc and negligible R
unless it's 100's of metres long. Tuned loops are the way to go. They are typically 5 feet
square with 15 turns and resonated with a 1000pf trimmer cap.
I use a coupling turn and connected it with coax to an
FT-817 through a Burhans (30-35 dB) preamp. DCF-39 (50 kw FSK station in Germany) could be heard on
138.830 kHz without a preamp. The 817 and many other amateur transceivers are quite deaf below 500 kHz, but are stable enough in frequency.
Several club members have heard DCF39 and some have received it using
a wire (or shorting the near end of the feeder on an 80m or trap dipole and using it as
an antenna) but the loop is usually better in terms of signal to noise.
DCF39 can be recognised as a continuous carrier, interrupted at irregular ~10 second intervals by
a 1 second FSK transmission. If you can hear DCF39, you have a good chance
of seeing amateur signals on 2200m with ARGO.
