Hi everyone,

On the picture above you can see the best part of my setup. As you can see it is oriented to SAT QSOs.

On the left there is 2x9el. TONNA cross-yagi RHCP with gain 13.1 dBi. On the right there is Cushcraft 719B 19el. Yagi with gain 15.5 dBi. Both are mounted on AlfaSpid azimuth and elevation RAS rotator, computer controlled. There are also 2m and 70cm preamplifiers (70cm preamp not visible on this picture).

Mast is of a special kind, it is standing on the roof by means of gravity. Calculations show it can withstand 175 km/h wind and sooner will slide than fall. Mast is connected to steel grounding 8mm diameter wire.

Then there is 40m coax cable (RF-10 cable, similar to H-1000) and my radio shack.Before cables enter the house, there is grounding plate with antenna feeder lighting protection devices. I can disconnect all cables if storm is coming (which is quite often a case during spring and summer in SP).

My radio shack is the smallest room in the whole house, and inside there is quite modest equipment.

My main rigs are classical old-timers: Kenwood TR-751A (2m All Band 25W) and TR-851A (70cm All Band 25W). There is also small handy and YAESU FT-817ND. Nice additions are external DSP (BHI NEIM1031) and 2m VLA-200 amplifier. Not shown on the picture is a rotator controller.

My station is sometimes used by me in remote mode (in that case FT-817ND is used), which configuration I am using mainly to receive FUNcube-1 satellite telemetry. You may find me on the ranking list: http://warehouse.funcube.org.uk/ranking.html (look to the top, HI) - (see CQ Amateur Radio Magazine, December 2014)


My activities 

My main activity are SAT QSOs. So far I worked on: RS10, RS12, RS13, F0-29, SO-50, VO-52, AO-7, AO-73, LituanicaSAT-1, Ukube-1, XW-2F (CAS-3F), XW-2E (CAS-3E).

►Quite often I receive telemetry and pictures from HAB (High Altitude Balloons): http://spacenear.us/tracker/

►I managed to receive some SSTV pictures from space, long time ago from MIR Space Station, recently from ISS (examples below).


► Reception of a telemetry from deep space probes:

- reception of a telemetry from the space probe 4M (Manfred Memorial Moon Mission, http://moon.luxspace.lu/). Amateur transmitter was attached to the last stage of a Chinese rocket probe Chang'e-5 flying on the trajectory leading to the Moon and back to Earth. I was among 29 (officially registered) stations on the Earth which received and decoded these signals. The maximum distance for my station to receive data from 4M was 267,000 kilometers. 

- reception of two probes launched with Japanese Hayabusa2 mission: Shin-en2 and ARTSAT2. In a team of Piotr SP5MG, Lukasz SQ5RWU and Michal SQ5KTM and few other friends we managed to receive Shin-en2 from 1.9 million km and ARTSAT2 from 2.7 million km (see CQ Amateur Radio Magazine, June 2015). We were using 4.5m mesh dish antenna, and a lot of additional equipmemt, software and computers. Our ground station was designed and integrated by our team. Some parts of hardware and software were of our original design. That was a great experience!



►From time to time I am active on HF with JT9 and JT65 modes. Especially I like to play with digital modes as QRP station during my travels. 

►EME for my little station is challenging task, but so far I managed to have a number of SWL and I also have a first EME QSO done (with great support form SP4K):

►With SP5MG I was among the very first users of FUNcube-1 linear transponder on 23-11-2013 at 20:44.


►Another recording: EVA-33 on ISS, recorded 2013/06/24 19:35 -19:42 UTC
Sound - LIVE reception with use of my amateur radio equipment, vision from NASA TV:




My other hobby is astronomy. I have built my own observatory where I take astrophotography pictures of a deep space. Here are some examples of my photos:





Please do not hesitate to e-mail me if you need a sked.

See you on SAT, JT9 or JT65 on HF, Meteor Scatter or even (one day) on EME,

Vy 73,

Peter SP5ULN
