Activity as EI8HH is over now

October 21st, 2020

QSOs in October 2020: MS in red, FT8 in green and SSB in blue

While refurbishing our irish home, I found some time in the mornings and the evenings to be active on 2 m. At least I worked 31 squares. Even on 23 cm I got 3 Calls to the log. The rig so far is an IC-9700 with a 7 element yagi and a linear amplifier with 200 W on 2 m and a 69 element yagi on 23 cm,

Now I have to close the station and take the antennas down. It has been a lot of fun and I hopefully will be back next year, if pandemic allows. Many ideas are in my mind now, how to improve the station over here.

Many thanks to Joe, EI3IX, his N adapter female-female allowed me, to run 2 m and 23 cm simultaneously 😉 .

EI8HH on Air

October 2nd, 2020

As some work at our families house in Ireland has to be done, I am spending 3 weeks over here in IO53HN. I got my new IC-9700 with me and have antennas for 2 m and 23 cm. As I have to restrict my movements by government order, no portable activites are possible in the first two weeks. So I will try to work in the UHF/SHF Contest on 23 cm from the southern lake shore of Lough Mask. My favourite direction is to GI/GM. Maybe I can go to a better QTH later in the 23 cm UKAC. On 144 MHz I will focus on meteor scatter in the morning hours.

In a first test on 2 m I worked GI and GM in FT8. GM7PKT came back on my very first CQ. Later I tried meteor scatter with my german neighbour Mathias, DH4FAJ. As he has massive QRM, he couldnÂŽt hear anything, but I copied him twice with +4 dB. So better to try in the morning again.

IC-9700: Drift on 23 cm

A question in a Facebook group about a GPDSO for an IC-9700 to be used on 23 cm for FT8 inspired me for a quick test. As I use my IC-9700 for 2 m and 70 cm only from home, I connected a dummy load to the 23 cm antenna socket. Next was to tune it to 1,296.174 MHz (of course) and to call in FT8.

The result in brief: No problem to decode, a moderate drift and the signal appeared about 100 Hz too low. Nothing to worry about.

But never the less, I prefer JT9f on 23 cm, as FT8 is useless on aircraft scatter.

Tropo to Belarus this Morning on 144 MHz

September 9th, 2020

A nice inversion could be seen out of the window of my shack this morning, promising good conditions. In fact I have been a little too far south for the duct, but at least I had two QSOs to Belarus in FT8.

Green: worked – Red: heard via tropo – Blue: heard via meteor scatter

The stations worked and heard via tropo have been in distances up to 1300 km. Occasionally signals appeared from more distant stations, 1500 and more km away. These could be decoded in one or two periods, then disappeared. Some reappeared later in the same manner, so itÂŽs very likely, it has been meteor scatter, as it happened in the early morning, when conditions are good for sporadic meteors.

Störungen durch “Wasservitalisierer” / “Wasserenergetisierer” / “Wasserstrukturierer” nach Tesla und Lakhovsky im 2-m-Band

September 1st, 2020

For quite a while now, mysterious signals can be monitored around 144.015 MHz at the lower edge of the 2 m amateur band. The alleged sources seem to be devices to “vitalize”, “structure” or “energize” water. The manufacturer claims, it will make drinking water healthier and can heal a wide span of diseases from oncologic and virologic to orthopaedic kinds. As the problem is wide spread over Germany, Switzerland and Austria, I decided to write the article in German.

Seit einer gewissen Zeit können um 144,015 MHz herum, am unteren Ende des 2-m-Amateurfunk-Bandes, mysteriöse Signale beobachtet werden. Die mutmaßliche Quelle scheinen GerĂ€te zur „Vitalisierung“, „Strukturierung“ bzw. „Energetisierung“ von Wasser zu sein. Laut Hersteller kann Trinkwasser damit angeblich gesĂŒnder gemacht und ein breites Spektrum an Krankheiten von Krebs ĂŒber Virusinfektionen bis hin zu orthopĂ€dischen Problemen geheilt werden.

Störungen durch Wasserstrukturierer, Wasserenergetisierer, Wasservitalisierer nach Tesla und Lakhovsky
Typische Signale der “Wasserstrukturierer” in WSJT Wide Graph

Der Hersteller gibt eine Soll-Frequenz von 144,015 MHz an, die Signale verteilen sich jedoch auf den Bereich von 144,010 bis 144,020 MHz und scheinen von sehr einfachen Oszillatoren zu stammen. Die FrequenzstabilitĂ€t ist dementsprechend sehr gering und die TrĂ€ger driften oft ĂŒber mehrere hundert Hz hin und her. Als Leistung werden 20 Watt angegeben, weshalb die Reichweite relativ groß ist und im Einzugsbereich des Frankfurter Flughafens sogar Reflexionen an Flugzeugen beobachtet werden können. Dort, wo Signale im Nahbereich beobachtet werden, wird auch von einer Rauschglocke berichtet, die sich ĂŒber das ganze Band erstreckt, was die Vermutung eines nicht sehr hochwertigen Aufbaus unterstreicht. Die Dauer der Aussendungen betrĂ€gt in der Regel 5 Minuten oder Vielfache davon. Allein im Rhein-Main-Gebiet scheint nach meinen Beobachtungen eine Anzahl von GerĂ€ten im höheren zweistelligen Bereich in Betrieb zu sein.

Da der Betrieb solcher GerĂ€te im 2-m-Amateurfunk-Band nicht zulĂ€ssig ist, sind bereits eine Reihe von Störungsmeldungen bei der Bundesnetzagentur anhĂ€ngig. Wer solche Signale mutmaßlicher Wasservitalisierer in seiner Umgebung beobachtet, sollte nicht zögern, eine Störungsmeldung bei der Bundesnetzagentur abzugeben. Eine möglichst genaue Ortsangabe der Störquelle erleichtert dem PrĂŒf- und Messdienst der BNetzA die Arbeit enorm. Einige Betreiber wurden auch schon ausfindig gemacht und Betriebsverbote ausgesprochen. Bei einem Preis im oberen vierstelligen Euro-Bereich ist das fĂŒr die Besitzer sicher ausgesprochen Ă€rgerlich, ganz abgesehen davon, dass nach TKG bzw. EMVG auch empfindliche Bußgelder verhĂ€ngt werden können.

Nach dem Frequenzplan gemĂ€ĂŸ § 54 Telekommunikationsgesetz ist eine Frequenzzuteilung fĂŒr derartige Wasserstrukturierer bzw. Wasservitalisierer auf oder im Bereich der Frequenz 144,015 MHz ausgeschlossen. Daher kann man davon ausgehen, dass es auch keine gĂŒltige EU-KonformitĂ€tserklĂ€rung gibt, die fĂŒr die Anbringung eines CE-Kennzeichens am GerĂ€t Voraussetzung wĂ€re. Ohne gĂŒltiges CE-Kennzeichen dĂŒrfen derartige GerĂ€te jedoch in der EuropĂ€ischen Union nicht in Verkehr gebracht werden. Wer also ein solches GerĂ€t in gutem Glauben erworben hat, tut gut daran, rechtlichen Rat zu suchen, um seinen Schaden gering zu halten.

Nach meiner Meinung sind hier skrupellose GeschĂ€ftemacher am Werk, die GerĂ€te mit einem vermuteten Materialwert im zweistelligen Bereich, die in der EU gar nicht verkauft werden dĂŒrfen, zu einem Preis im oberen vierstelligen Bereich an kranke, gutglĂ€ubige und möglicherweise verzweifelte Menschen verhökern. Die, die diese GerĂ€te dann kaufen und betreiben, wissen in der Regel gar nicht, dass das illegal ist. Genau genommen sind sie also nicht TĂ€ter, sondern Opfer. Paradox ist , dass auf vielen Internet-Seiten, wo diese GerĂ€te angepriesen werden, gleichzeitig Produkte zum Schutz gegen “Elektrosmog” im Angebot sind.

New Dutch Beacon PI7RMD

June 23, 2020

PI7RMD is on air for quite a while now on 13 cm. I already spotted it on May 3rd, 2020. Looking at the entry at beaconspot.uk wondered, why no one else sent any spots. So I had a look for it today and got some nice reflections via aircraft scatter.

PI7RMD is located in JO31AD, using a double quad antenna beaming 270° with 5W ERP. It is keying in A1A on 2320.8948 MHz (nominal 2320.895 MHz).

The IC-9700 Effect?

June 16th, 2020

It was nice to paricipate in the recent Microwave Contest on first weekend in June. There was a lot of activity despite the fact, no multi operator stations have been there as big guns. Meanwhile the claimed scores for DL are available and I was surprised by looking at the number of german participants on the 23 cm band. 174 stations sent their logs, which is much more than the total numbers of single and multi operator stations in the past years.

So I guess, it may be caused by the popularity of the new ICOM IC-9700 SDR transceiver, covering the 23 cm band.

Addendum June 17th, 2020: Pit, DK3WE, the contest manager, had a look for me at the .EDI files and found among those, who entered the equipment, 40 entries of IC-9700.

Going for the Hydrogen Line

May 31st, 2020

I have been curious about everything about the hydrogen line for quite a while. So at least I mounted a feed for 1.4 GHz in my 3 m dish, installed a LNA at the feed, as well as a Pluto SDR and SDR# with the IF-Average plugin. First steps are very promising, as I saw something, when beaming to Cassiopeia and Swan.

Due to the doppler shifted signals the lines are smeared (red marks). The spikes seen, are just interferences.

New Bands down to DC

May 7th, 2020

Yesterday I added a logarithmic periodic antenna for the range 28 to 150 MHz to my little antenna farm. So I am QRV now on the amateur bands from the highest DC band 28 MHz up to 2400 MHz.

Antennas at DJ5AR

Recently I got an IC-7300 with extended frequency range to cover the 50 MHz and 70 MHz, as well as the new Irish bands 80 MHz and 60 MHz.

So I am looking forward to have some cross band QSOs to Ireland soon!

I took down the 3 cm dish for some work on the rig. And I know, the 70 cm yagi is much too close to the new antenna, but I have been too lazy to dismount it.

Addendum May 18th, 2020

First PI4 decodes of EI1KNH in IO63VE on 40 MHz.

AirScout V1.3.3.0 released

May 3rd, 2020

The VHF/UHF/SHF contest on 2nd to 3rd of May was a good opportunity to spend a few hours trying the new AirScout version 1.3.3.0 released by Frank, DL2ALF. In principle it works like itÂŽs predecessors, but is more stable in collecting the aircraft data. My favourite in this case is planefinder.net.

Most impressed I am by the new feature to monitor a number of paths to certain stations simultaneously! This provides more efficiency in arranging skeds, particularly in times like these, when there are a few planes only are available.
