On Sunday, September 13, the large dish in Dwingeloo (25 m diameter) will be active during the ATV contest. It is only possible to receive because it is not allowed to transmit with the dish below 10 degrees elevation. With the enormous gain of this dish, not only the large, but also the small stations get the chance to create a nice, sharp picture in Dwingeloo, of which a photo is also made and sent on request. It will be received under the call PI9CAM and the operators are Jan PA3FXB and Jaap PA0T. We are qrv at 70cm, 23cm and 13cm. And DATV is also possible, also at 2 meters.
Due to the Corona regulations, the dish can only be used for four hours and we are therefore only available qrv from 8:00 - 12:00 local time on Sunday morning (6:00 - 10:00 GMT).
Unfortunately, QSO cannot be made via 2 meters due to the aforementioned transmission ban. We use the internet application DXSpot, see https://dxspot.batc.org.uk/. Creating an account is necessary, do this in time. During these four hours you can also communicate via Whatsapp with telephone number 06 86875497.
Corona rules may be tightened, causing the event to be canceled. We will make this known in time.
For any questions or skeds: Jaap PA0T (firstname.lastname@example.org) or Jan, PA3FXB (email@example.com).

Dwingeloo managed to receive both Rob and I at ~ 500kms on 70cms.

I switched on 70cm with 25W 125Ks DVB-S and they saw me pretty much straight away.
I tried 23cm but nothing was seen of me which was strange although the wind was VERY strong so i could have been off heading a few deg, it was hard to line up accurately.
The 23cm system was working fine as i was accessing GB3NV a bit later on.
That's what ~37dB gain / 25m antenna does for you
Problem with such big dish is openingsangle.
On 3 degrees on 23 cm1 degree and on 13 cm less than 0,5 decrees plus an offset bedause de feeder on 13 cm is aside the box in the focus.
We tried long on 23 cm but no signal from you.
We noticed that once de ant direction is ok whe had steady b3 to b5 signals.
It was a nice experiment; maybe repetition and longer qrv.
