JT65 stations on 5 MHz (2)

Tonight I logged a 5 MHz QSO between G3SUY and HA4YF in JT65 mode. G3SUY transmitted in the lower part of the channel, 5357.5 - 5357.7 kHz, according to the British 60 m allocation and the recent warning of RSGB:

1920 -14  0.3  525 # CQ G3SUY JO01
1921  -6  0.2  525 # G3SUY HA4YF JN97
1922 -11  0.3  525 # HA4YF G3SUY R-08
1923  -4  0.1  525 # G3SUY HA4YF -07
1924 -12  0.3  526 # HA4YF G3SUY RRR
1926 -13  0.3  526 # HA4YF G3SUY 73


Also at 19:35 UTC I received beacon HB9AW in CW on 5291.0 kHz, confirming that it remains active.
 

Beacon HG7BHB QSY to 5352.5 kHz


20151214-0318-5352 5-HG7BHB-0007
Screen capture of beacon signal at ipernity.com
Yesterday afternoon I noticed that the Hungarian 60m beacon HG7BHB moved to a new frequency, 5352.5 kHz. It still transmites the same message as before:VVV DE HG7BHB QTH JN97LE 34SF PWR 50W. This morning at about 03:15 UTC (05:15 local time) I can hear it with very good signal strength and some occasional deep fading (QSB).

JT65 stations on 5 MHz

This afternoon (2015-12-11) I left my receiver on 5357 kHz USB, where there is some European JT65 activity. I used the WSJT-X decoder version 1.5.0 by K1JT, with an internet connection to PSKreporter

When I came back I found that the receiver had logged CQ calls by five Dutch stations: 

15:06 PA3RIS JO31
15:19 PE1RNU JO32
15:20 PA9CC  JO32

15:49 PA3BUD JO21 
16:16 PE2HHN JO32

There were no actual QSOs between these stations or with anyone else. 

So 5 MHz activity is picking up, I hope we gain access to this band soon.


UPDATE: One minute after posting this message, at 1634 UTC, I also logged two CQ calls by A45XR from Oman on LL93.

WSPR beacons on 5 MHz


After the promissing decision of WRC-15 about a 5 MHz allocation, I decided to spend some time investigating the propagation in this band more closely. In the past I monitored occasionally the British CW beacon chain on 5290.0 kHz using the GB3RAL software by Peter Martinez, G3PLX. Unfortunately beacon GB3RAL (IO91in), which was the most reliable signal of the chain at my location, is currently off the air, and signals from GB3WES (IO84qn) and GB3ORK (IO89ja) are much weaker. I also spent some time with aural reception of other European 5 MHz beacons during local nightime, like DRA5 (JO44vq) on 5190.0 kHz, HB9AW (JN43ba) on 5291.0 kHz and HG7BHB (JN97le) om 5357.0 kHz

Recently I started monitoring the WSPR (or "whisper") digital beacon network on the same frequency. I downloaded WSPR 2.12 from K1JT's site. It installed easily under Windows XP. It requires a soundcard and two serial ports (one for CAT and one for PTT via DSR or RTS). This information is set in the Setup->Station parameters menu and saved using File->Save user parameters. Also, as we have not yet access on 5 MHz, we must disable the transmitter. This is done by moving the "TX fraction (%)" slider on the main window to the left (zero). The receiver dial frequency is set to 5287.2 kHz by selecting Band->60 m and the mode is set to USB manually.

WSPR also requires very good computer clock accuracy, which I achieved by changing the SpecialPollInterval setting in the registry, which can be found under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\TimeProviders\NtpClient (this seems to work only under Windows XP, some different approach is required for Vista, Windows 7 and later derivatives). See "Adjust Internet Time Synchronization" by Arie Slob for more detailed instructions. An alternative, recommended in Radio User, is the Dimension4 NTP program, available for free at http://www.thinkman.com/dimension4 .

There is an internet server at http://wsprnet.org/drupal/ where the WSPR program can upload spots for decoded beacons. This feature is activated by checking the "Upload spots" box in the main window. The WSPRnet site includes a WSPR spots database and a world map of uploaded reports. Unfortunately the map does not update automatically.

Until now I have received WPSR beacons from EA, G, GM, I, OZ, PA, DL and other European countries. I hope to receive beacons from North America, the best time being after local midnight, when the noise level decreases substantially.

Flash and strobo tube data

During the last few days I tried in vain to locate online the base pinout of an octal xenon flash tube type STC150, like the one shown on the picture.  Finally I discovered a discared box of a related but physically different device, a Velleman S106A flash tube.
STC150

On the two sides of the card I discovered the pinouts of some flash tubes including the STC150, the associated trigger transformers, plus a small table with some technical data. I upload it here so they are available to anybody interested.

Connection diagrams for flash tubes and trigger transformers

 
Technical data for flash tubes.

The tubes included in this data sheet are the U-style S106A, S8538, S4668 and the octal base STC150.

A scottish shower by Athens digisonde


This morning I discovered that the Digisonde of the National Observatory of Athens is once again accessible on-line at its usual URL: http://www.iono.noa.gr/  . Let's hope that it remains active in the future, as it is essential for local NVIS communications, and for tests on the new 60 m (5 MHz) allocation.

Λευκός καπνός: New Band at 5 MHz


Απόψε η IARU εξέδωσε την ακόλουθη σημαντική ανακοίνωση, για την οποία είμαστε σε αναμονή από την έναρξη της WRC-2015:


During todays (November 18th) afternoon plenary session of WRC-15 in Geneva a new amateur service allocation at 5 MHz was approved. Although only a small allocation of 15 kHz between 5351.5 - 5366.5 kHz was eventually agreed it is the first new allocation at HF since the WARC of 1979. After intense pressure from the Fixed service primary user, power limits have been set at 15 Watts eirp in Regions 1 and 3, 20 Watts eirp in Mexico and 25 Watts eirp in Central America, South America and most of the Caribbean area. 

Region 1 Member Societies not having an allocation under Article 4.4 of the Radio Regulations are urged to contact their administration to have this narrow segment included in their licence, although the new Radio Regulations will not come into force until the 1st January 2017.


Όπως έχει γραφτεί σε διάφορα sites, η απόφαση αφήνει όλους εξ ίσου δυσαρεστημένους. Προφανώς αναφέρεται στους τυχερούς, οι οποίοι είχαν ήδη εθνικές κατανομές στην ζώνη 5.2-5.4 MHz με μεγαλύτερη επιτρεπόμενη ισχύ. Συγκεντρωτικές πληροφορίες για τις υφιστάμενες κατανομές στις διάφορες χώρες θα δείτε στο άρθρο "60-meter band" στην αγγλική Wikipedia.

Στην Ελλάδα οι ραδιοερασιτέχνες ζουν εξ αρχής μια ιδιάζουσα κατάσταση, με έντονη εχθρότητα και καχυποψία εκ μέρους των κρατικών αρχών,(*) με εξαίρεση την περίοδο μετά τον σεισμό του 1999 και την υπουργία του κ. Μαντέλη. Μέχρι στιγμής κάθε νέα εκχώρηση και παραχώρηση προς την Υπηρεσία Ερασιτέχνου εφαρμόσθηκε με τον πιο "τσιγκούνικο" τρόπο και αφού εξήντλησε τα χρονικά όρια, πρόσφατο παράδειγμα η ζώνη 7100-7200 kHz. Μπορούμε να είμαστε αισιόδοξοι ότι αυτή τη φορά η νέα κατανομή συχνοτήτων θα εισαχθεί σύντομα και χωρίς "αστερίσκους" ? Θα μπορέσει η διασπασμένη σε πολυάριθμους συλλόγους ελληνική ραδιοερασιτεχνική κοινότητα να εμφανίσει ένα συμπαγές μέτωπο προς τις αρμόδιες αρχές ?

(*) Όσοι το αμφισβητείτε, διαβάστε πρώτα το βιβλίο "Από την αναμονή προς την αναγνώριση" του SV1AIA.

UPDATE 2015-12-15: Σήμερα ελήφθη και η σχετική επιβεβαίωση μέσω LoTW από τον επετειακό σταθμό 4U1WRC που λειτουργούσε παράλληλα με την WRC-2105 από το club station του 4U1ITU.

Beacon HG7BHB on 5357 kHz

20151114-2209-5357-0007

Tonight at 21:45 UTC I noticed a new beacon on 5357 kHz with callsign HG7BHB repeating the following text in A1A CW: 

VVV DE HG7BHB QTH JN97LE34SF PWR 50W

The beacon is not listed in the G3USF worldwide list of HF beacons. It is located inside the proposed worldwide 60 m amateur radio allocation.

Also earlier at 21:10 I heard DRA5 from Germany on 5195 kHz. However I could not hear any of the three British beacons on 5290 kHz.

Intruder on 14240 kHz


20151109-0621-14240-0005 20151109-0631-14240-0006

This morning around 0620 UTC, 14240 kHz was occupied by a continuous FSK (F1B) transmission with 250 Hz shift. Possibly the same Russian military station which shows up on 14192 kHz. 

At 0630 UTC the station switched to F1A (frequnecy shift morse code) and exchanged short messages like "QRJ2  QRJ? K" with unid stations on another frequency. After that it went off-air, at about 0632 UTC.

The IARU Region 1 Monitoring System reports on this frequency a Russian Military station from Irkutsk in CIS-50-250 mode (September 2015 bulletin).

ITU 150 awards

Many amateur radio societies have organized within 2015 special award comptetitions for the 150th anniversary of ITU. The competitions come in the form of one or more special event stations with interesting prefixes. QSOs with them lead to some type of award.

RAAG SX150ITU award
The first award I managed to complete was the SX150ITU award from RAAG in Greece.

URE  ITU-150 Silver
Then the URE award from Spain, silver class.

MRASZ ITU-150 bronze
Finally today the MRASZ award from Hungary, bronze class.

I also qualify for the polish award, but I have not managed to apply using their web page.

There are more news, next Monday, the 2nd of November, the World Radiocommunication Conference 2015 (WRC-15), opens in Geneva, Switzerland, and shall last to 27 November 2015. Let's see what interesting prefixes are on the air for this event.

MX beacon K on 7039.3 kHz

20151028 MX K 7039.2 kHz
Tonight I heard again after a long time the Letter Beacon (MX) "K" on 7039.3 kHz. This beacon is located in he Russian Far East, possibly near Petropavlovsk-Kamchatsky according to the IARU Region 1 Monistoring System and the HF underground wiki. While other beacons of this cluster moved out of the 40 m amateur radio band to 7509 kHz, this one remained on its old frequency.

LPD RTTY beacon


Today I received a Radiometrix NTX2-434.650-10 LPD transmitter module which I ordered on eBay from mallinson-electrical. I integrated it with an Arduino Uno, a female SMA socket and a 3λ/4 antenna to build a small RTTY beacon. Output power is about 10 mW, consistent with the LPD specification CEPT/ERC Recommendation 70-03.

I programmed the Arduino with a modified version of M0UPU arduino code, which is published on the site of UKHAS


Reception of the LPD beacon using fl-digi

I hope some time within the next weeks to make a test transmission from a high location so anybody interested can get some hands-on experience with dl-fldigi reception of balloon signals.

The interesting news is that Radiometrix produces a new version of the transmitter, called NTX2B-FA, which is frequency programmable, so it can be tuned to more appropriate amateur radio frequencies near 432.8 MHz.

Dasher beacon on 7010 kHz


This morning, at about 05:20 UTC, the dasher beacon showed up again on its regular frequency just above 7010 kHz. I am not sure if it is actualy a dasher or a single letter beacon with id "T". 

This beacon is frequently heard during local evenings but usually it passess unnoticed, as its signal is lost below CW QSOs on this busy frequency.

HABE Greek Adventure (2)

Today I had the chance to test DL-fldigi with a real balloon downlink, using the weak signal from HABE. I used an Icom IC-7100 radio connected via USB to a PC running Windows XP and DL-fldigi version 3.21.50. The antenna is a tribander vertical (6m, 2m, 70 cm) with a 15 m RG-213 transmission line. 

Screen capture of FL-digi in action
I understand that the balloon trackers transmitted telemetry using LPD devices at a power of only 10 mW. Modulation was FSK (nominally 425 and 850 Hz shift) with ASCII encoding. Shortly after lift-off, FL-digi managed to decode a number of packets on 434.650 MHz and 434.200 MHz and upload them to the HAB tracking server, before the balloons drifted to the north, behind Mt Parnis.

I would like to see in the future some experimental beacon with GPS telemetry using the FL-digi specific format, which would help us fine tune our receiving systems.


For further info, read the on-line manual: Beginners Guide to Tracking using dl-fldigi , on the UK High Altitude Society (UKHAS) Wiki.

New DX worked during CQ WW RTTY

Last weekend I participated in the CQ WW RTTY contest. The operation was fairly succeful:
  • I worked E51AAR, South Cook Island, on 20 m for an All Time New One (ATNO), getting my DXCC total to 277.
  • I worked OJ0DX on 80 m and Z21MG on 10 and 20 m for new band slots. I had Z2 only on 6 m, due to limited activity from that entity.
  • Finally I worked L33, OM2015, A96, HB2 and perhaps a couple more new prefixes for WPX Mixed and WPX Digital.

I have already sent my contest log as Checklog and uploaded all QSOs to LoTW, eQSL.cc and ClubLog.

See you next month (October 24-25, 2015) in CQ WW SSB.

SV1GK: Τα είπε όλα σε μια πρόταση...

"…Αυτό πού με θλίβει... είναι η ανύπαρκτη διάθεση των συναδέλφων [ραδιοερασιτεχνών] να διαβάσουν για να πλατύνουν τις γνώσεις τους, αλλά κύρια ο άκρατος εγωισμός, η αρχομανία και ο διχασμός πού επικρατεί μεταξύ τους…"

Athens Flying Week 2015 - Tatoi Air Show

Yesterday I visited Dekelia (Tatoi) Air Base (LGTT) for the main air show of Athens Flying Week 2015. There were many interesting participants from Military and General Aviation, as well as Aegean Air.

Unfortunately the spectators area has poor orientation; for most of the air show the spectators and photographers face the Sun.


A small collection of my photos is uploaded to my ipenity.com account.

Εφαρμογή τύπου APRS από την ΤΡΑΙΝΟΣΕ


Η ΤΡΑΙΝΟΣΕ Α.Ε. έχει αναπτύξει μια συμπαθητική εφαρμογή στο internet, η οποία προβάλλει σε χάρτη τις θέσεις των αμαξοστοιχιών σε επιλεγμένα τμήματα του δικτύου. Προς το παρόν καλύπτονται οι ακόλουθες διαδρομές:
  • Κιάτο - Άνω Λιόσια - Αεροδρόμιο (προαστιακός)
  • Χαλκίδα - Πειραιάς, με μετεπιβίβαση στις Αφίδνες
  • Θεσσαλονίκη - Λάρισα (προαστιακός)
Τέτοια κόλπα στον χώρο των σιδηροδρόμων μέχρι στιγμής είχαμε δει μόνο στην Ελβετία (http://maps.vasile.ch/transit-sbb/), και μάλιστα από ιδιώτες και όχι επίσημα.
 
Η διεύθυνση για πρόσβαση της εφαρμογής είναι: http://www.trainose.gr/traingps/ και χρησιμοποιεί υπόβαθρο Google Maps. Μήπως θα πρέπει να τους μιλήσει κάποιος και για το OpenStreetMap, το οποίο καλύπτει άριστα την συγκεκριμένη εφαρμογή ?

COMMON AND PRECIOUS update (TNX QSL)


Yesterday I visted the post office, where I found a QSL card from german beacon Common and Precious, which operates on 10237.6 kHz CW from a location near Aldershof in Germany. Many thanks and 73 to the operator!

 


Athens Flying Week 2015

The opening "pre-show" of the Athens Flying Week 2015 took place yesterday evening over Phaleron Bay. The program included:

  • The Saudi Hawks (aerobatic team of 7 BAE Hawk of the Royal Saudi Air Force
  • Flypast of Aegean Air A320 and Olympic Air Dash8Q400
  • Three ultralight seaplanes of Aviodream
  • Jurgis Kairys flying solo his Su-31
  • Polish AF Mig 29 "114"
  • Sea rescue demo of the Hellenic Navy Helicopter Command

It seems that the Hellenic Navy helicopter display did not go as planned; the S70 helicopter failed to recover the rescuer who was subsequently collected by a RIB of the Hellenic Coast Guard.


There was also a team of UAV drone operators from Ucandrone who produced live video coverage of the air show and the spectators using two quadcopters.



More photos from the event are available at my ipernity.com photo collection.

The air show continues on Saturday 12 September and Sunday 13 September at Dekelia Air Base (LGTT).

DXCC 275 entities


Last April I received the endorsement sticker for 275 DXCC entities (mixed). The next one is for 300 entities, very unlikely to achieve it.


UPDATE: Recently updated to 276 entities, with a paper QSL card from 7O2A, Yemen.
