Operation Schedule / Signal Reports 2018

1 Dec. Start Opera32. 50 watts 137.477 kHz to big rl. OPDS detections at DF6NM and IZ7SLZ. PSKR: 2E0ILY EB8ARZ PA0RDT. This is the first LF opera transmission since November 2016. DOCXO, AD9850, arduino uno, TC4426 keying the IRFP260n class E tx using a python script on a raspi3.
3rd reports from Domenico IZ7SLZ and Graham G0NBD who marvelled that the EB8 got a daytime reception. Several spots on psk reporter 2E0ILY G0LUJ EB8ARZ SM2DJK PA0RDT PA0LSB.
4th. Bernd, DF9RB reported on 10 receptions peaking -32dBOp at 0600 at DL0AO. Stefan DK7FC sent similar report.
5th. Checking out the 7400 XOR modulator module. Evidence of phase shifts seen on Markus spectrogram. 6th Try Ebnaut. DF6NM reports reception of a frame from K3RWR and 'HHERTZ' from here at 2300. Running 50 W to big rl. Now try 10 watts... Then 4. Decodes by IZ7SLZ, W1VD, VE2IQ (Carrier detect),K3SIW and DF6NM and W1VD who decoded the QRP (4 watts) transmissions. 7-8th: EbNaut 50 watts, 7 chars, 8K19A, 608 3 s symbols. rx at DF6NM,K3SIW,DL0AO (137.477 kHz, 7 Chars, 8K19A, 3 s symbols, 608 symbols, starting h:00 ut) 17th. Continuing wiht EbNaut. The class E TX is holding up well. Received by DL7FC, the EbNaut autodetectors at DF6NM and DL0AO. Report from Marco DD7PC for the transmissions on the 14th. 18th. High SWR and Hot heatsink on TX... aerial had been grounded by wx (ice,wind). Last EbNaut message rec'd at DL0AO at 0700.

Here's the low power setup before the gps upgrade. Centre: B+ set to 20 volts with variac on the power supply as seen on meter. Below an arduino programs an ad9850 via 10 pos'n switch. The dds is clocked by an oscilloquartz 10 MHz DOXCO. Front of dds: BPSK modulator module comprising a 7400 configured as an XOR gate with leds showing in and out. Front of modulator: 2n222 and tc4426 keying and driving stages; left: a class E 100w TX for 630m, collecting dust awaiting revised RBR4 at the moment) left: Admy. Patt. key. Above: class E for 2200m. Same one used in 2003 experiments but sith IRFP260 instead of IFF640 hexfet. The former has a lower fatality rate.
19th. Big RL tangled in tree tops by wx. Clipped the tower tap on coil; carrier restored 1500ut.

(Thanks to DF6NM for the above plot)
and this summary. 21st: daytime copy on grabbers. 22: gps disciplined carrier at 2015 ut today. 23rd good copy at K3SIW. 25th: EbNaut messages copied by K3SIW and W1VD. 26th. 18 dB Eb/No Rank 0 report from K3RWR. 29th TX off 2300ut. Scaled the hill in a raging blizzard at night to switch from LF to MF.

29 Nov 2018. Switched on the power supply for the home brewed amp and continued with the 50 watts QRSS30 transmissions. A fortnight ago, the far halyard on the big RL failed, bringing latter to the ground. Feeding the tower with the Decca caused the far halyard on the low (VLF) RL to fuse, bringing it to the ground too. Also had to fix a mess of charcoal that was once a cleat anchor. 30 watts of VLF back on to the low RL and 50 watts on the big RL again. Strong sigs seen on N1BUG grabber without amp during test transmission using just the TC4426 driver connected to the coax!
18 Nov 18. The far halyard was replaced. The burnt halyard of the low RL was repaired and the insulator raised again. Energising the tower with LF when the big RL is down is not kind to the VLF halyard. Tuned the coil back to 1.7 mH from 2.6 mH and ran the Decca on 137.777 with some QRSS30 and QRSS60.

2 November 2018. 1 or 2 modules of the Decca to the high RL (20x30m) 3rd. switched to CW on 136.5 kHz following report from Roelof that the QRSS was audible.

Markus' high resolution spectrograms showing 5 nights of carrier and one of QRSS100 with th keying sidebands just visible.

Markus sent this capture from the club station DL0AO.

Meanwhile to the west, Gary K3SIW captured a few letters.

And to the East, Alex RN3AUS does well too. The QRSS on 1 Nov was sent with 1 module of the Decca; about 150 watts, 2 amps of RF to the antenna.
4th: CW 500 watts to 20x100m RL. Ended when a windstorm severed the far end halyard and shattered an insulator. The rotated "L" is in a heap on the ground. Fortunately Roelof was recording: PA0RDT audio Linrad, 12 Hz SDR, Miniwhip. 5th: N1BUG reported clear cw reception at time last night. The tower was used without top loading but was base loaded with 2.7 mH.

12 Sep. hf heard by n1bug and here too 137.0 khz. 13 0040 tx on after shutdown for Lightning. 8Sep. Demo t vo1hp get-together at freshwater. Pwr increased to 15 watts. Copied in st brides (135 km )

2 Aug. Continuing with 4 watts on 136.4 kHz to the big rotated L. Copied by VO1FOX at Signal Hill. 9th VO1LM heard weak sigs. 2200ut. Remote rx Whitbourne: rx with ft817: Burhans+ loop sm6lkm converter and pa0rdt mw. No copy with mw and 817 or lkm + eco whip or lkm+loop. Latter 2 appear to be limited by noise.

9 July 137.777 kHz QRSS100 200 watts to big RL. Captured on DF6NM grabber along with R7NT who was up 0.5 Hz. 10th 4 watts 136.38 kHz CW to big RL. Aerial earthed 12th, 15th.

13 June 2018. QRSS100 on 137.777 kHz starting ~0015. Seen on DF6NM grabber.

21 March. A few days testing on 137.777 kHz started as soon as the aerial was raised. Moved to VLF (8.2700075 kHz) tonight.

10th. Markus reported on the carriers for the past 3 nights. 'It is well visible all over Europe, e.g. on Chris' uHz grabber in Bucharest. He noted the first was about 2 mHz high. The Raspi3 was not following commands to disengaging the AD9851 clock multiplier. A uno was used and the carrier is near the expected 137.7770002 kHz. The clock is a 10 MHz doxco. 11th. Trying again for a distance record. 3.6 amps. to the big RL. The attempt to link the antipodes was brought to a halt when the 50' mast supporting the far end of the big RL came down in 158 km/hr gusts. 12th: ad9850 comparator output via 4426 to the Decca. Using a box from the Loran site (formerly used for freq calib). between the MAR3 and the DDS clock input. The output now seems clean on the NM grabber. 17th. testing ref osc amp(2n3904, 74LS04) ad9851 & raspi3. checking on df6nm grabber. Good line on 137.77701 kHz as expected. Misc tests of DOXCO amp, dds, rpi3 software -- seems all ok on df6 high resolution grabber.

16 Feb. 2 Decca modules fed by ad9850 \& onboard comparator + 4426 driver. arduino freq/phase word and cw message generator. and 20x100m aerial.

Wolff RN3AGC RN3AUS and SQ2BXI 13 Oct. Reports from WA3TTS F6CNI F1AFJ RN3AGC and 2E0ILY. 13-14th: A sudden drop in signal levels. The Kyoto dst plunged 131 points and CFH could not be seen on the DF6NM grabber at times. CFH has been active for several weeks after a long hiatus.

SQ2BXI on the 12th.
19-20 Oct. Seems CFH is now QRT again. Tried OP32 on a raspi after the ardino went on the blink. A nice report from Joe DJ2JP for whom this was his first TA OP reception.

Reports from DF2JP and F1AFJ. Traces seen on the DF6NM grabber for almost the whole period including daytime.

Operation Schedule / Signal Reports 2015

Paul and Markus' phase/magnitude data of dec 2015.

December. Various tests with EbNaut. 5th 131 characters sent in less than 11 minutes. Received by PN and DF6NM on 4th-5th. 5 second symbols starting morning of 5th. Received by PN during day.

Pauls plot. Offset = -255 uHz.

November 01: RN3AGC veak trace. 04 QRS100 5A RF good strong copy at DF2JP. 05,06 OP32. Reports of good decodes at DF2JP, IZ7SLZ and SV8RV. Pskreporter log: G3XKR DF2JP EI8JK G3XDV 2E0ILY. Thanks to all. 07. Reports of OP32: DF2JP G3XDV IZ7SLZ SV8RV TF3HZ G3XKR PA7EY SP5XSB SV8RV DK7FC. Also DF6NM who confirmed the carrier phase was adequate for EbNaut experiments. 08 QRSS100 137.777 kHz 09: OP32 137.477 kHz. 09: OP32 Reports from G3XDV DF2JP IZ7SLZ and the usual insightful commentary from G3NYK explaining the good prop. in light of the -80nT DST and the poor reception at TH3HZ. 2 hops, but sometimes 1 and 3 as well... OP32 again tonight.

DF6NM analyses the signal. A 0.7 mHz error and temporal fluctuations of 0.5 mHz. The TX was off for a while before 0304 utc to prevent interference to a scope. Markus observed a 0.1 mHz error in LORAN sidebands near 137 kHz which was likely due to Doppler from ionosphere motion. Thanks to Chris 2E0ILY Iban EB3FRN Ulrich PA3EY and Graham for reports and email and about a dozen spots on pskreporter for the transmissions on 10-11th. 11-12: OP32 5.4 amps to the 100m wire. DOXCO was adjusted today (first time in 2 years) and there was some tower work -- top guy saddled and a new halyard.
11-12th. 5.2 amps op32. Frequency correction apparent on DK7FC IZ7SLZ and DF6NM sites.
18th. DOXCO restored to original calibration (5.29 volts on VCO). A rounding error (TNX DF6NM) causing the OPDS freq to be low by 0.7 mHz. was corrected. Phase shift experiment and QRSS transmissions.
21st. Finally sent a phase shift across the pond! Much jubilation and cat excitement. The event was heralded by evidence from Markus (Germany) and Paul Nicholson (UK).

DF6NM Spectrum

Paul's spectrum. Earlier today the more recent 100m wire was raised again.
22nd November. First attempt at EbNaut (137.777000 kHz 8K19A 13 chars 896 symbols 2s duration 29:52 total sequence time) resulted in transatlantic disappoint, a disgusted cat and profanity. Software engineering glitch? 24th November. The cat's name crosses the pond as confirmed by DF6NM P. Nicholson and IZ7SLZ. 25th EnNaut received by P. Nicholson and IZ7SLZ. 26th. PN, DF6NM and G4JNT. 27th. TX on 2000 using CHU for timing again. 29,28,30. ebnaut including day transmission. Night decodes by P.N. and DF6NM. No daytime copies though Paul could see the carrier.

30th -31. DF2JP strong, and RN3AGC traces of sigs.
29th. G3XDV G4WGT and RN3ACG kindly provide traces and reports.
26-27th. Mucking about with the VLF/LF/MF exciter followed by a test run to ensure it still works on 2200. 5 amps 100m wire. Fuzzies at first (seen on DF6NM G4WGT and DK7FC grabs). Then removed exciter xfmr and put big xfmr (tnx G3LDO) before tuning coil. Seems to have reduced fuzzy sigs. Report of strong (audible 0100) at DF2JP. Traces reported by Alex RN6AUS in Moscow.
20-21st OP32 5 amps RF till 0157 then 2.2 amps. 6dB drops were seen on the DK7FC and DF6NM OPDS reports as well as 1 mHz freq. accuracy. SV8RV copied OPDS 2 frames (QRA 5905km). G0NBD provided compliments on the signal strength as well as updates on the PSKreporter. Thanks to all for the grabs/reports/ encouragement! OP32 reports from LA3EQ PA3ABK DF1VB PA7EY G4WGT DF2JP and G0NBD relayed by Graham.
19th Another strong cap by PA0RDT with traces 1.5 hours past dawn.

PA0RDT capture 0656-0816 2 hours after his local sunrise at 0609.

DF6NM high res spectrum showing sidebands, phase coherence, freqency accuracy and possible post dawn peak.

13 Reports from SV8CS and DF2JP 14. DF2JP
SV8CS Capture
17th. Audible sigs at PA0RDT, despite (recent) poor conditions following a dip in DST.

11-12 Oct. 3 Decca modules engaged and no fuzzies or incoherent phase seen on the DF6NM high res grabber. Nice caps seen on G4WGT Dk7FC grabbers. Joe DF2JP sent a nice capture without fuzzies. The syth, u-processor and keyer/divider/driver were partially dismantled and reassembled with more shielding in an attempt correct the phase/freq instabilities. It seems there may have been some ingress of carrier to the synth.

7-9 oct. 200 and 500 watts. Fuzzies only at higher power.

5,6 oct. DF2JP observes fuzzy signals. Iban EB3RFN has clear sigs on the 6th. (lower power was used)

Testing CW on 136.500000 kHz. ~10 watts to 100m wire. Not heard at 60km with miniwhip.

March 01 3 Decca mods. 3 apms RF QRSS100 on at 2047. (still daylight) Shortly after TX on air, DF2JP reports improved sigs and on the morning reports" the most outstanding signal I┤ve ever seen from your side." The sigs were audible. Good reports from F1AFJ (>20 dB over noise) GW0EZY (fuzzy sigs) although not sure why they were fuzzy G4WGT too(sigs nice & clean). Lovely sidebands were seen on DF6NM's high resolution spectrum.

Henny's PA3CPM capture shows sidebands and fuzz!!??

2nd: More reports of fuzzy signals from PA3CPM, G4WGT, GWEZY and DF6NM.

Gary's plot.
A trip up the hill on snowshoes in the dark and cold last night (3rd) revealed the cause of the problem. Wind had blown downlead against the wood ATU frame causing part of the latter to go up in smoke.

DF6NM reported stable signals again last nigt. 4 Mar. Reports: PA3CPM DF2JP YV7MAE DD7PC F1AFJ. No fuzzies this time. A greyline fadeout was observed by DF2JP followed by a brief return to 1041 UTC. 5-6 Mar. Reports from PA3CPM DF2JP and PA0RTD with whom the sigs were audible. TX off 1112 6th. Another greyline fade/return at 2JP. TX on 2111 6th. 7th: reports from PA0RDT, PA3CPM and another daytime reception up to 1200 by DF2JP. The TX was switched on again today at 1306. 3.8 A RF QRSS100 to the 100m RL. Daytime copy at DF2JP, W1VD and W1DEX. 8th. PA3CPM PA0RDT(audible) EW6BN.

Last 2 gave QRG as 137.476999 kHz. 28-29 Oct. 4 amps to 100m wire. Reports OPDS and PSK Reporter: LA4ANA LA3EQ SM6BHZ DL-DWL F6CNI GW0EZY G4WGT G4MDH G3YXM G0KTN G3XDV SV8RV G8HUH EW6BN DF6NM (UNTIL 0733UT) TF3HZ W1VD W1TAG/1 30th. G8HUH and F6CNI, who reported audible signals.

30th Good reception at EW6BN.

1st. 5 Amps from the Decca with 3 PA's engaged. 100m wire at 15 m high. F1AFJ: "monsterous signals" maybe saturating his agc. OK2BVG and PA3CPM report very strong signals. EW6BN reported good sigs too. F1AFJ sends an MP3 of the audio. Incredible to actually hear the signal! 2nd. Weaker sigs copied by F1AFJ and PA3CPM.

After months of delay, new 40 amp 600V rectifiers are installed in the power supply for the Decca 5501. Hopefully they will survive longer than the single-unit bridge rectifiers did. A 234/80V 18A xmfr is used with a choke input filter. 27th. QRSS100, 500+ watts, 4 amps to the 100m wire. Reports from DK7FC G4WGT. 28th. F1AFJ and Lubos, OK2BVG, and traces reported by G4WGT in heavy QRN and Yuri, EW6BN. 29th: F1AFJ copies 30 dB over noise at audible level. OK2BVG copies a full call sign
and Henny PA3CPM sends
a spectrum showing very strong sigs, and a strong capture were received by Gary G4WGT and Stefan DK7FC. All 3 Decca modules were engaged with 5 amps of RF. The Decca PA's became quite warm, as did the 1.44 kVA xfmr, but the rectifiers, cooled by a small fan on the heatsink, remained cool. 30. Another audible reception by F1AFJ

and a report of less clear sigs was received from VE2IQ, 1800 km over land to the west. 31. Good copies at PA3CPM and F1AFJ. An apparent frequency shift of 0.01 Hz was noted on the DF6NM hi res grabber. Markus explained that a computer issue caused the LORAN frequency lock to be lost and the free running xtal drifted down as it cooled. A record breaking July in terms of temperature has not resulted in excessive heating of the TX system except for the LV (25V 1A) xfmr which was too hot to hold.

1st: Running 80 watts from one Decca module (HT=40V). 1.2 Amps RF to the 100m wire. QRSS100 Phase coherent 137777000 Hz (as monitored on DF6NM high resolution grabber) Nice spectrum from Henny

13 April

Despite the high A,K indices (25,3), UW8SM, DK7FC, DF6NM and R7NT were copied last night. For RX, the 100m wire (usual TX aerial) was used. It has 2 mH of series inductance. The RX was the FT-817 without the external (35dB) preamp. IPO was engaged (to remove the internal preamp) and the AGG was off.
15 Apr. DF2JP DF6NM and DK7FC copied.
17-19 Apr. 70 w to 100m wire. DF6NM F1AFJ and F6HCC reported reception of the QRSS100 sigs. 20th. F1AFJ reports sigs along with those from XGJ , XES and XEB. The wire is covered with ice and the current is very 19th. F6HCC also reports sigs despite low aerial current due to icing. 23rd Reports from: PA3CPM F6HCC IZ7SLZ & F1AFJ (strong sigs) 29th PA3CPM F1AFJ KL1L (nil) 30th PA3CPM F6HCC (online DF6NM nice sidebands) and F1AFJ.

01 February. 4 watts output. Lovely clear copy at Hartmut's, Trace reported by PA3CPM. Poor copy on 4th but much improved on the 5th at PA3CPM. F1AFJ grabber showing good sigs. 7th G3XDV copies OP32 sigs. 9th G3XDV reports "Consistent signals from VO1NA (3742km) on 137kHz Opera32 last night. Nothing seen on the Opera software, but OPDS produced decodes at 0308, 0343, 0418, 0453 and 0603UTC, all around -40 to -43dB S/N." 11th. OPDS at DF6NM following power increase from 4 to 6 watts. Also TF3HZ. PA3CPM and DF6NM report copy and traces. 15 Feb. 16th. Wire is lowered in anticipation of sleet and wind storm. TX off. 18th. G3XDV requests stations to send some OP32 so raised wire but it is fouled by 2 trees.

June: Trying a new signal source and phase coherence. DF6NM gives a positive report, but identifies areas for improvement wrt phase glitches and freq chirps. Accuracy not too bad: 137.77702 to 137.77704 kHz. Another daytime copy at VE1VDM at 840 km away. Traces starting to appear on F1AFJ grabber at 2330 utc. 3 June. TX still on. Report from Michel F5WK of chirp which is readily apparent against the loran line. Reception on F1AFJ grabber 2300-0450 utc. F1AFJ reception between 2320 (3rd) and 0420(4th). 4th. Checking for thermostat transients in the freq of the docxo o/p. Put a 6dB bjt amp between the docxo and dds. 5th: reports from G4WGT and DK7FC who received the sigs between 0050 and 0300 utc. Markus in a critical report said the sigs looked better and the QRG was "137777.0028, give or take a couple of 100 uHz." It also seems the chirp and phase glitch problems have been resolved. Thanks to all! TX on again tonight 2330. 6th. Andy F6CNI checked the stability and found better than 0.005 Hz over 2 hours. Jay V1VD switched the RX ant to get a strong copy as well. 7 June: Plans are made following discussion on the Blacksheep news group to try 137.555 kHz for Op32 experiments. 18 June. DF6NM measures frequency as 137.7770000 kHz. DOXCO and synth seem to be working well together. 22 June OP32 transmissions commence 0000 on 137.555 kHz. Receptions have been recorded at G3XDV G4WGT G3XDV GW0EZY PA0OCD DF6NM DF5JP and W1TAG. It seems the summer equinox TA path is open from 0000-0500 utc. Markus sends an informative spectrogram. The sigs are phase coherent, accurate and stable, and agile as we are no longer rock-bound to 137.777 kHz as for the past decade.

Particulars of the new station were sent to the Blacksheep RSGB reflector. 23 June. Reports of OP32 reception from DF2JP (using 1m rx loop) and DF6NM. 24 June. TX power reduced from 450 to 150 watts.

30 October: OP32 receptions : 2113 PA0A -38 dB and 2202 DF6NM -36 dB.

September 01: OPERA32 starting 2200 UTC. 137.777 kHz 4.5 Amps Reports from GW0EZY(-28dB), F1DTL(-40), W1TAG(-40), G4WGT(-25) and DF6NM(grabber). 03-05 OP32. VE1VDM(-26) and DK7FC(-40) Reports received so far: GW0EZY F5WK DF2JP F4DTL G4WGT G8HUH VE1VDM and W1TAG. 6th: DFCW copied by GW0EZY. 11th: Reports of good reception fron DK7FC and W1VD(25 dB s/n in 28 mHz) and GW0EZY who noticed the post dawn enhancement. Alan, G3NYK offers a masterful explanation: " I think you will find that the shadow is around 1/4 of the way into the path. This suggests to me that the 2nd ionospheric hop point of the signal has been washed out by the solar radiation. The remaining signal maybe a weak one-hop (!) or possibly one night hop followed by two daytime D-layer hops. I think this is unlikely, but dont role it out, but D-layer daytime skywave is usually weak in the early morning. "

31 Aug-1 Sep: DFCW 4.5 amps. Reports from Terry GW0EZY and Martin YV7MAE.

29-30 Aug. Initial try with ARGO 8 and 32. Then DFCW.

Operation Schedule / Signal Reports 2011

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 noticeable 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 the first transcontinental LF transmission from this station.
Jacks reception on 137.777 kHz about 0400 utc on 13 December. WD2XKO is also visible at 137.7777 kHz. 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, 29 PA3FNY 30 PA3CPM. 30 Another daytime reception by M0BMU.

Reports received from PA3CPM F1AFJ and DF6NM who reported the frequency as 137.777016 kHz. 12: 1 kw 4.5 amps to a 100m wire for brief operation. 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 propagation and reports were gratefully received from PA3CPM and PA3FNY.

  • 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.

After some aerial work the current increased to 1.2 amps. 10: Traces by G3NYK and CT1DRP along with my WD2 colleagues XDW XES and XGJ. TA conditions are generally poor according to G3NYK but 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.

    Timeline and signal reports:

    Please note that signal reports and frequency measurements are appreciated.
  • 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. Station Description

    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.

    Alan G3NYK has an excellent site, complete with propagation information and an easy-to-use spreadsheet implementation of Sokal's Class E Amplifier design equations. There are several other excellent sites on the internet, for instance ON7YD. More sites and a list of other Canadian LF experimenters are available at Steve's VE7SL site Steve's old site Propagation info and forecasts can be seen at Alan's G3NYK Propagation page.
