Planet Ham

A new DX record for terrestrial (non EME) communication has been set with a QSO between D44 and CT on July 10th over an incredible 2696km. See http://www.hyperatlantica.ch/ for more information.

Hoy he empezado en 17 mts en Orcoyen,parecía que en 10 y 15 no había nada.Así que habría que ir acercándose a los 20 poco a poco.

En 17 he cruzado el charco con una estación especial de Puerto Rico K4C y he vuelto a trabajar a los de 6V7W.Ya los tengo en 3 bandas y en el log ya aparecen los contactos de 20 y 10 mts.

Me ha costado el de Puerto Rico la verdad,ha sido a base de insistir.

He pasado a 20 y la propa no estaba tan larga,llegaban bastantes EA con el prefijo especial de los Mundiales.

Mañana es el último día para usarlo,asi que ya podéis aprovechar.Yo no tengo intención de usarlo pero me parece un motivo interesante para encender el equipo,hacer contactos y disfrutar de la radio.

¿Una vez más donde digo digo digo Diego y te hago un truquillo? ¿O es un error tipográfico?.Aunque sea pesado si todavía existe la unión y el interés se puede hacer lo que no se hizo. ¿ O no interesa? ¿Son las cosas distintas ahora?

Visto desde fuera parece que una madeja ordenada se ha liado y nadie tira del ovillo.

Today I increased the power from my QRSS3 136.93kHz beacon to 2W out of the PA into the 20m spaced earth electrodes. Another "ride about" test locally with the deaf FT817 and E-field probe RX antenna gave the following results:


These reports are roughly "end on" to the electrodes and I've yet to try other directions such as orthogonal to them. No attempt was made to match the PA output to the impedance presented by the earth electrodes which are around 40-60 ohms below 10kHz; I've not measured it at 136kHz yet.

Even with true QRP it looks like a range of at least 10km should be possible on QRSS3 (and probably WSPR) with a half decent receiver (better than my crude set-up) using just a 20m earth electrode TX antenna on 136kHz.  I'll leave the QRSS3 beacon running over the weekend on 136.93kHz from my QTH in Burwell, Cambs (JO02dg) and any reports and screen shots would be much appreciated.

Check it out here – nice photos too. Pre-built, not a kit. No mention of QSK capabilities yet.

After pondering tree geometry with the idea of putting up an inverted L for the coming fall/winter season, I decided to just make further use of what I already have – an 80m dipole & its feedline. The idea isn’t original – it came from my well-worn copy of ON4UN’s book on lowband DXing.

Below is a modification of a diagram in the book that more accurately reflects what I want to do.

My main concerns are avoiding ground loops and in utilizing the right relay that will provide minimal loss and maximum isolation for my 100-watt station. Ground loops and relays at RF are both gray areas for me so I plan on picking the brains of those more worthy in this area than I am…

I suppose the relay shown here would be referred to as a DP3T 3PDT (thanks Mike!).

I began the radial installation this weekend by mowing the grass short and using lawn staples (75 for $10 at Lowe’s) to hold down the wires. According to several sources, the wires should be invisible within a week or two. I’ll be able to use elevated radials along the fencelines of my yard.

After several mowings of the yard, laying additional radials each time, I will have a radial system as good as it’s gonna get around here.

Chiedo scusa alle diverse persone che mi chiedono come mai il blog è fermo, in termini di aggiornamento. Bhè, il motivo, come già successo, è il tempo! Solo motivi di tempo che mi hanno impedito di aggiornare con regolarità questo “diaro di bordo”. E’ un periodo, questo, di particolare intensità lavorativa, al punto da faticare nel tovare un pò di tempo, e a volte di energie, per buttare giù qualche post.  Ma non preoccupatevi, nei prossimi giorni tornerò ad aggiornare questa mia finestra sul mondo. Il viaggio in Irlanda e la visita all’Ham Radio di Friedrichshafen, saranno tra gli argomenti affronati. Intanto, seppur in ritardo, buona estate e buone ferie.

I'm trying to optimise an IRF510 MOSFET PA for use in the 136kHz beacon and later transverter design. Alan Melia G3NYK has a very useful page on practical approaches to class E designs for 136kHz at his page http://www.alan.melia.btinternet.co.uk/classepa.htm together with a useful Excel worksheet to come up with practical values for the output network. Class E using square wave drive on the input can produce very good efficiencies, thereby reducing heatsink requirements.

The six meter calling frequency and perhaps other calling frequencies on other bands are a bit of a paradox.  Six meters is often dead and will magically open up between areas due to Sporadic E propagation.  You won't know the band is open unless you continually scan the lower end of six meters hunting beacons or someone happens to be calling on the calling frequency.

We have an amateur in the area who likes camp out on the six meter calling frequency and have his voice keyer automatically call CQ for a few hours some evenings.  It's logical to do such a thing as no one will know the band is open unless someone is transmitting and someone receives the transmissions.  But it's terribly annoying to listen to and I find myself getting frustrated when people do this.  I know others feel the same way as well.  Despite being a calling frequency it's impolite to use it for calling for long periods of time.

Perhaps what we should really have are multiple calling frequencies based on areas such as grid square fields, the first two characters of the Maidenhead Locator System (i.e. "FN", "EM", "CN", etc.).  You could camp out on the frequency for your grid square field and call CQ all you like, but if you just wanted to listen for an opening, you could leave your receiver on one of the other grid square field frequencies and not have to worry about a local station clogging the frequency for long periods of time.

A year and a half ago my LoTW confirmations were at 14%. Either more and more people are starting to use it or contesters are more apt to use LoTW than non-contesters. Most of my QSOs as a function of percentage in the last 18 months have been made during various contests and sprints.

Android is popular linux based operating system for most of smart phones and also tablet PCs. Some said that android based phones is an iPhone killer. Can we run an android on your x86 pc ? yes we can!

Steps

1. Get android x86 iso here at http://android-x86.googlecode.com/files/android-x86-1.6-r2.iso
2. you need UNetbootin to make bootable USB drive or just burn the iso if you got cd/dvd drive ( you can also run this iso in your virtual environment, vmware, virtualpc, virtualbox )
3. reboot your pc to your USB drive or burned cd/dvd

Today I started to modify my 136kHz QRP beacon to increase the power from 250mW to around 5W using an IRF510 MOSFET PA. I've still work to do to optimise the design but hope to complete this tomorrow.

A rather long, but fascinating article on the possibilities and issues with time travel is on Wikipedia.

VK3QB, VK2CA, VK3HJ y VK3CBV operarán como YJ0VK cerca de Port Vila en la isla Efate del 27 de agosto al 2 de setiembre.

Esperan poner en el aire 2 estaciones,con gran interés en las bandas WARC.

El equipamiento y los sistemas radiantes son importantes.

Researchers at MIT may have come up with a way of travelling through time (and space) using quantum closed timeline curves or CTCs. It has always fascinated me that in quantum mechanics one can describe things as wave functions that have existed in all space and all time, past present and future. It takes a leap of imagination to consider the possibilities. For an explanation see http://www.telegraph.co.uk/science/7904712/Quantum-time-machine-allows-paradox-free-time-travel.html

This is the abstract of the original MIT paper:

"This paper discusses the quantum mechanics of closed timelike curves (CTC) and of other potential methods for time travel. We analyze a specific proposal for such quantum time travel, the quantum description of CTCs based on post-selected teleportation (P-CTCs). We compare the theory of P-CTCs to previously proposed quantum theories of time travel: the theory is physically inequivalent to Deutsch's theory of CTCs, but it is consistent with path-integral approaches (which are the best suited for analyzing quantum field theory in curved spacetime). We derive the dynamical equations that a chronology-respecting system interacting with a CTC will experience. We discuss the possibility of time travel in the absence of general relativistic closed timelike curves, and investigate the implications of P-CTCs for enhancing the power of computation."

I have no idea what caused that horrendous QRN on 20 Meters the other night; but I have been hanging around and listening to 20 Meters tonight; and so far there is no sign of it. The weather here is the same as it was Tuesday night - hot and humid, no rain.

I am sure that it will probably not rear its ugly head again until the next time I am scheduled to be the 20 Meter Fox in a few weeks.

Sigh.

However, I did manage a very quick QSO on 30 Meters with HP3DX. K2 and the Butternut got me a 449. Bill was about 569 here.

Libano. Spionaggio per Israele, Berlino smentisce arresto di un tedesco

http://www.loccidentale.it/articolo/libano.+spionaggio+per+israele,+berlino+smentisce+arresto+di+un+tedesco.0094066

Il governo tedesco ha smentito le notizie circolate nelle ultime ore sulla stampa libanese in merito all’arresto nel Paese dei Cedri di un tedesco sospettato di spionaggio a favore di Israele. È quanto riferisce l’agenzia di stampa tedesca “Dpa”.

“Non c’è nessun procedimento” aperto contro Manfred Peter Mog, ha affermato un portavoce del ministero degli Esteri di Berlino, precisando che l’uomo è stato interrogato dalle autorità libanesi, ma non è stato arrestato. Ieri la stampa libanese riferiva dell’arresto di Mog, che lavora per un caseificio nei pressi di Baalbeck, da parte delle forze di sicurezza del Paese dei Cedri.

Secondo il quotidiano “An Nahar”, l’uomo è responsabile della manutenzione dei macchinari del caseificio. Sempre ieri ‘As Safir’ riportava che l’uomo era sotto interrogatorio e che, in particolare, gli inquirenti si stavano concentrando sul suo uso di apparecchi per le trasmissioni. Dallo scorso anno le forze di sicurezza libanesi hanno intensificato gli arresti tra le persone sospettate di essere spie al soldo di Israele, dedite alla collaborazione con il “nemico”.

Dal 2009 sono oltre 70 le persone che sono state arrestate in Libano per attività di spionaggio a favore dello Stato ebraico, con cui Beirut è tecnicamente in stato di guerra. Almeno tre persone sono già state condannate alla pena di morte.

I have often heard it said that, "If you listen to the radio long enough, you will hear everything." I think that in 30+ years as a Ham, that finally came true the other night.

I was driving home from work and had the Icom in scan mode. It settled on one of the repeaters in New Jersey that is linked for statewide coverage. I heard a Ham relating the following story.

He was driving through a certain town and got stopped by a police officer for going over the speed limit. He was also on the radio at the time. In New Jersey, when you get a speeding ticket a certain "point value" goes on your driving record, depending on how far above the speed limit you were traveling. If you accumulate more than 12 points in three years, your license to drive is subject to revocation. The Ham must have offered some kind of sob story and the officer must have felt sorry for this guy, or something, because he offered him a choice. He had to issue a summons; but was willing to avoid giving the guy the points for speeding if he would take a ticket for using an electronic device while driving. This is New Jersey's cell phone law. If you use a cell phone (other than a non-hands on system) while driving, you get a fine. The Ham agreed to the cell phone ticket instead of the points.

What the officer didn't know, it seems, is that there is a specific exemption for Amateur Radio operators built into that law. As far as the law is written, Amateur Radio is NOT cell phone communications and is therefore permissible while driving.

So our friendly "lead foot" Ham was explaining to his friend on the air how he is going to court to challenge and possibly have the driving offense expunged on the technicality.

I was perturbed. First off, the police officer did this guy a favor. Even though Joe Ham broke the law by speeding, the police officer gave him a break by charging him with a lesser offense with a smaller fine and no points against his driving record. Joe Ham freely admitted his guilt and freely admitted that he was going to try and get out of this on the technicality that the police officer was probably unaware of. How about taking responsibility for your actions and taking your medicine like a man? As it is, he should be eternally grateful to the police officer for not issuing him the speeding points.

Secondly, if this guy's argument works; and he does beat the ticket .... how is that police officer going to treat other Hams in the future? He will have gotten burned by one of us once. Think that's not going to reside in the old memory banks for a long time? Think this police officer is going to be sympathetic to some other Ham in the future? I doubt it.

This kind of thing makes us all look bad. Fortunately, the friend that "lead foot" was talking to on the repeater advised him against his planned course of action. The friend was trying to be the voice of reason and common sense; but somehow I don't think his advice will be heeded. It seems that anything goes these days.

I will keep an ear open to this repeater system over the next few weeks. I will be very interested to see how this turns out.

He hecho un nuevo contacto con XT2EME desde Orcoyen,esta vez en 18 MHZ.Me ha comentado Jorge que estaba en 18140 y he pasado,a la segunda con split 5 arriba lo he hecho.Se acordaba del QSO en 6 mts en móvil y me lo ha mencionado.

También he vuelto a trabajar a los de Senegal,esta vez en 14.

Jorge me ha contado un poco sus aventuras en el concurso de 6 mts y también he podido saludar al Txoska y a EA2CFR.

He dado una vuelta por 20 y he escuchado alguna PY de lejos a parte de lo ya trabajado.También una IOTA en Noruega.

Cuando iba a aparcar el escaneo de memorias se ha parado en 144300,y he escuchado una estación muy fuerte y una bajita.

Me interesaba la bajita,asi que me he hecho presente y he podido saludar a EA2LU Jorge,que era la fuerte.Con él estaba Nicolas EA2AGZ.Le he llamado y me ha contestado.

Me ha tocado pararme en el semáforo antes del puente que a la derecja se va a la RENFE.Ahí me tapaba un edificio y casi no lo escuchaba.Cuando he pasado el puente,justo encima he podido saludar a Nicolás.Me ha hecho ilusión ese contacto con la cuarto de onda de 1 €.

Al aparcar todavía lo seguía escuchando.
