August 8, 2017: ARISS contact with the International Space Station….twice!
Todays ARISS contact went a bit different compared to the “regular” contacts.
The contact was scheduled between Paolo Nespoli in the ISS and the Youngsters On The Air 2017 event at Gilwell Park in the UK.
When the contact came round, it was clear that after a few attempts, Paolo could hear us, but we could not hear him over the downlink. HamTV did pick up some of the audio, but due to delays, this audio is difficult to use during the contact.
The Flight Director kindly rescheduled the contact on the next ISS pass and moved it to the service module, to be able to use other equipment on the station.
The second attempt was a great success!

June 9, 2017: Veron Pinkster Kamp radio camp
I have attended the 52nd “VERON Pinkster Kamp” radio camp last weekend. During the camp, Ivo PA1IVO and myself gave an amateur radio satellite introduction and demo.
I made videos of the opening, demo and closure of the camp, which can be found below (in Dutch!)
March 15, 2017: PI6WL outdoor tx unit
For the PI6WL ATV repeater, I have built a new (temporary) outdoor unit. This should reduce losses in the feed cable and also provides visual indication of the internal fuse state
February 25, 2017: HamTV contact
This video is a recording of the hamvideo downlink from the international space station, as received in Delft. JO21ex. It was part of a school contact between Thomas Pesquet on the ISS and Ecole primaire Elie Desplan, Boissières, France and Marie Castang, Saint Dionisy, France.
February 17, 2017: Nayif-1 launched, alive and kicking!
On the 15th of February, Nayif-1 was launched on a PSLV with 103 other satellites.
I have been spending the past week at the American University of Sharjah, United Arab Emirates, in the mission control centre. Also, we have been visiting the Mohammed Bin Rashid Space Centre to give a training to their education team.

We have received one pass with FUNcube and Nayif-1 in view at the same time.
In the doppler plot below, you can see both satellites.
February 13, 2017: HAMTV received
Today, the International Space Station transmitted live video during a school contact between Thomas Pesquet on the ISS and Collège André Malraux, Chatelaillon-Plage, France. The signals were received in Delft and forwarded to a central server.
The video received in delft can be found below.
December 31, 2016: New BY70-1 satellite transponder
I have been trying to use the new BY70-1 transponder lately.
Information is still a bit sparse, as this satellite is Chinese.
Working conditions are:
TX via Home QTH: Diamond X50 vertical and IC-910h
RX via the TU Delft station.
RX operator: Nils von Storch

December 28, 2016: Beach day – lots of starfish (sea stars) washed ashore
Today, we were visiting the beach, and found loads of starfish washed on the shores.
Apparently, a strong current in the Noth Sea loosened them from the seabed. A beautiful but cold day, but its a sad sight to see all these dying starfish. Nature is cruel.
October 31, 2016: PI6W test repeater – testing 23cm
Today I managed to get the first signals through the 23cm input of the test repeater that should become PI6W.
I used a yagi from the window on the front side of my apartment. This gave B4 images on the repeater.
The received images are the signal received by Jaap PA3HGL in Spijkenisse, from a reflection and Herman PB0AHX in Delft.
October 18, 2016: JOTA 2016
The JOTA 2016 is over. We ranked 9th in the JOTAcross game. I still have to count the QSOs, but it was a pretty low number.
We did have some nice ATV QSOs, although the other two groups that were visible did not have the audio enabled, so they did not hear us.
A new type of tower was tried and it was a success. We did break one pole, but the rest survived, including the rope holding the tower during hoisting.
We streamed the three days live to YouTube and were on ATV on Saturday and Sunday.
Unfortunately, the EME contact we scheduled did not work out because the volunteers at the 25m radio telescope CAMRAS in Dwingeloo went home at midnight, and I only became QRV around 01:30.

August 2, 2016: Colloquium is now over – I was awarded the G5RV cup!
The colloquium was a great success, and apart from meeting old an new friends, there were also some highlights to the trip.
First of all, the ARISS-UK team presented me with a team polo shirt at the colloquium, A principia mission patch and a pin badge. The same evening, the whole ARISS-UK team was awarded the G3AAJ Trophy.
On top of that, I have received the Louis Varney (G5RV) Cup for advances in space communication.
I am very grateful to be awarded this cup, and this stimulates me to continue working on AMSAT satellites.
We gave a presentation for ISIS at the colloquium, and got a big thumbs up from the audience.
Having arrived safely back at home with all equipment, I am currently editing all the video that was recorded during the weekend, and publishing this on the AMSAT-Uk YouTube and my own YouTube channel
