Bell'ascolto ! Tra le montagne...

Mi pare stiano facendo un gran lavoro, sono solo 4 operatori non scordiamolo, non si sa quanti qso abbiano fatto, non avendo comunicazione web con l'esterno, ma mi aspetto numeri importanti.
Forse potrebbero dedicarsi di più alla fonia, li ho sentiti e collegati solo in 17m ssb, avevano un bel rate, forse varrebbe la pena...

Re: TI9A Cocos

Ieri in 160 avevano un segnale ottimo, li ascoltavo anche con l'antenna tx, stamattina invece arrivavano appena sopra il rumore e avevano un rate di qso molto basso circa uno ogni 3 minuti abbondanti, e rispondevano ad americani ed europei, solo che stamattina c'era meno della metà di chiamanti a causa del segnale molto basso, stessa cosa hu1dl che ha chiamato una buona mezz' ora ( al nostro SR) senza che nessuno gli rispondesse, l'ho ascoltato fino alle 8:15 e chiamava a vuoto. nel giro di 24 ore le condizioni in 160 son cambiate in peggio, mentre in 80 alle 8:15 Ti9A, segnava ancora S9...

questo è il filmato di ieri preso alle 4:00 ora locale ( prima di andare al qrl) e alle 7:14 ( quando son tornato di corsa) e non c'è stato verso di passare, mentre stamattina con la santa pazienza ci son riuscito ( grazie al fatto che c'erano meno della metà di stazioni di ieri)
Antenna RX ewe ( doppia misura)

l'audio è scsarso perchè a quell' ora devo mettere il telefono nelle cuffie per registrare...


10 minuti fa in 30 metri cw arrivava molto bene, e son riuscito a collegarlo dalla Buca del mio QTH.

Re: TI9A Cocos

Eccolo in 17m SSB, purtroppo c'è stato poco, ha detto che il rate era bassino e preferiva il cw.

Re: TI9A Cocos

Un bel segnale in 17.

Re: TI9A Cocos

E niente, io non ho ha mostrare alcun video. Purtroppo per me questa DXpedition si è rivelata una delusione. Li aspettavo dove potevo collegarli, 20m CW (non ho altre bande attive per ora) , ma non c'è stata una sola volta che li abbia potuti ascoltare decentemente. Segnale bassissimo e , come accade in casi simili, *****i a go-go isofrequenza
Ho provato a sentirli nel primo pomeriggio (caso peggiore secondo Voacap per la mia tratta) e la sera: nisba. La mattina, invece, li ho visti spottati sempre e solo in 80 e 40m.
Va be, se non ce la farò neanche oggi, pazienza. Fortunatamente ho la conferma in 10m e 15m SSB e CW (TI9M nel 2002).

Re: TI9A Cocos

stanotte in 160 metri sia con il TI9 che con 5I5 mi sono sentito come la mosca che cerca di forzare il 'campo di forza' ...

Re: TI9A Cocos

In 160m. non ho antenne ,ma stamattina in 80 cw, TI9A mi ha acchiappata, ho fatto molta confusione in rete, anche perchè proprio non me lo aspettavo. Il segnale era buono, tra un ascensore e l'altro.
I nostri in 20cw con Alfeo al timone mi arrivavano a palla, giusto prima di uscire per andare a far spesa. Soliti 70w al mio K3 e la superpensionata DX88 .

Re: TI9A Cocos

Ormai lo avete visto tutti, comunque mettiamo il link del log online.

Mi pare che, compatibilmente con le condizioni di propagazione da minimo solare, ma soprattutto direi dal numero esiguo degli operatori, 4, abbiano fatto un buon lavoro.
Sono convintissimo se non certo, che sarebbero arrivati anche in 15m in Europa, magari non ovunque ma tanti li avrebbero collegati, ma visto il periodo del ciclo forse ci possiamo accontentare.
Sacrificata l'Asia.

Re: TI9A Cocos

non Hanno avuto vita facile, come spesso succede nelle spedizioni in posti così remoti e privi di comfort...
4 persone di cui uno pure col dito tagliato a causa del drone impazzito, installare antenne nella foresta, e far si che siano "performanti" non è sempre facile... complimenti davvero, perchè hanno focalizzato il traffico per il massimo che potevano fare in quelle condizioni e nel poco tempo a disposizione.

TI9A Cocos Island News 10 February 2020
Four exhausted but happy operators arrived safely back to San Jose after the nine day DX adventure (including 2x36 hours boat transfer) to Isla del Coco.

We managed to work 28000+ contacts during 6 days of operation, and considering the challenging circumstances we are very happy with the results. Low Bands were kicking and we managed to work almost 2000 contacts on Top Band, with huge amounts of EU and other DX in the log. 80/40/30 were brilliant as well.

As with all expeditions, there will be people who are very happy, and others who expected more. We are humble enough to acknowledge that any expedition has their successes and less excellent parts.

As we did not have any internet at all during 9 days, we could not get any help from the cluster or from kind hams sending emails. We had to rely on our own belief, what was best for the DX community.

Some issues we would like to clarify:

The initial plan of having a CW/SSB camp on the hilltop above Chatham Bay was a good one. We wanted to separate those modes from FT8, with interference as main reason, and antenna space as the other. Chatham Bay beach location is not intended to accomodate all antennas, due to the jungle terrain.

However, the "road" from the base camp to the hilltop (600 meters of walking and 150 meters of vertical elevation difference), had completely deteriorated and we soon realized that we would not be able to in an energy-economical way transport 2 x 100 kilo generators, 500 litres of petrol, antennas, equipment, food etc there. If we would have decided to do so anyway, we would have lost approximately 2-3 days of the limited days we already had due to licence limitations.

The decision was made to combine CW/SSB with FT8. As you all can understand, this is not ideal due to the planned amount of stationed we intended to launch at the same time. and a VERY narrow and difficult jungle terrain all the way to the beach.

Nevertheless, we managed to get up fullsize antennas for 160-12 meters. All of them proved to work excellently to almost all directions. The only direction with really a drawback in signals were VK/ZL. Sorry for that, but we worked some VKs via Long Path anyway.

Complaints have been raised on our CW focus. The explanation is easy: Our fellow TI9 colleagues (TI9C) had announced a very focused effort on SSB, as they do not seem to operate CW. As we did not encounter them on the vessel to Cocos Island, as expected, we decided not to cannibalize their opportunities for a future SSB expedition. Contradictory to our own assumption, that TI9C would perhaps not appear at all, one well-known and respected source of daily DX information, insisted few days before our operation, that he was assured through a personal call from that group, that operation still would take place.
Due to the uncertainty of that other operation, we took the decision to lower the priority for sideband operation.

Nevertheless, we indeed spent quite some efforts on SSB when we felt conditions were good enough for that, and when we maintained acceptable rates on SSB. When we felt the rate was not at a good level, we simply went to CW to ensure that people could get a chance to at least work us there.

Regarding the FT8 issues we had, what we would like to make people understand that working this mode from a remote island without ANY internet at all, is very different from sitting in the cozy DX corner at home, with broadband Wi-Fi and all other commodities. We had a portable GPS-2-USB device to ensure the synchronization. That procedure needed to be repeated with a few hours of intervall, as we understood gradually. With the extensive use of RF in the place, the GPS signal was heavily affected, and this eventually had a very serious consequence, as our drone, to be used for attaching a 160 meter Inv L wire, started to operate and move without our control. The propeller of the drone unfortunately in high speed hit the finger of Jorge TI2JV, with the result of lots of blood all over... The paramedics in the Ranger team on the other side of the island needed to appear on a Zodiac vessel, evacuate him to the paramedic station and make three stitches on Jorge. It could have ended much worse.

Other comments are referring to the promised 24/7 hours of operation - or what appeared to be a "failure to comply with that promise"... We did indeed take a few small naps in between (on average no more that 2-3 hours per night and person). This was necessary to recover from a very intense antenna setup and walks up to the hilltop in order to evaluate the feasibility to at all work from the hilltop location, made us simply exhausted. Sorry for that guys. However, very few hours were unattended overall and we did utilize the time on the air as much as we could.

More details will follow, but this description should "kill" most of the speculations, and understand a bit better why we did like we did. At last but not least, remember that this island is quite challenging with climate, tidewater, insects, rats (not the small ones you are used to), screaming wild pigs appearing directly at the camp, destroying antennas and whatever. AND, those rats were not only outside our abandoned ranger hut. They were our nightly friends in Cocos Island "Hilton Hotel".
