I am pleased to report that on Wednesday, April 3 I had my first contact on satellites with Ireland.  Joe, EI5EV and I completed it successfully on FO-29. We had just a 66 seconds window but there was enough time to exchange reports and greetings. I believe that it is the first contact between Ireland and Cuba on FO-29! It is a 4321.7 mi (6955.1 km) contact!

Our first attempt was yesterday but Joe couldn’t find me on the passband. We made a schedule again and we tried to be more accurate on frequencies calculation. Doppler is always in play!

We did the calculations based on the great feature implemented on SatPC32 V12.8b. There is an  option of seeing the frequency you are at the satellite receiver.  This was our common reference point. I was very satisfied when I heard Joe exactly on the frequency I was expecting!

I was operating portable from a tall building `s roof which allows me a great horizon visibility forwarding Europe. I was running my new FT-817nd, a 30W power amplifier and a homebrew ARROW antenna with a homebrew mast mounted preamplifier. Everything was supplied by two 12V 7A Gel batteries.

Right Now, FO-29 has a big footprint. Please, if you are into the footprint and want to try a long distance contact, just drop me an email. I will try until complete a contact with you.

Thanks very much to Joe for this great contact!

73!

Flight Refueling Amateur Radio Society (FRARS) were active on the amateur radio satellites on Thursday, April 4 using the special event callsign G100RSGB .

On one pass of the satellite FO-29 club member Clive Lambert-Hutchinson G7SVI had arranged a schedule with Hector Martinez CO6CBF in Cuba. This was on the extremes of range for the satellite and there was only a brief window of about 1 minute when the two stations could make contact. A signal believed to be Hector was heard but wasn’t strong enough for a contact.

FRARS hosted the RSGB Centenary Call G100RSGB from their club house at Merley, Wimborne, Dorset, BH21 3DA and were active on all bands from 1.8 – 440 MHz. The day was a great success with the club members operating three separate stations continuously during the day.

FRARS are a friendly club that welcomes newcomers. They are holding another Foundation training course on the weekend of April 13-14.

PicoDragon is a 1U CubeSat project intended to take low resolution Earth images and to test on-board systems.

It is planning to use two amateur radio downlinks and frequencies for these have been coordinated by the IARU. The 100mW CW beacon will be on 437.250 MHz and a 1k2 bps AFSK 800mW AX.25 telemetry downlink on 437.365 MHz. Commands will be uplinked on VHF.

The Vietnam National Satellite Center VNSC say that Pico-satellite Dragon is expected to launch in mid-2013 on a Japanese rocket.

NASA Seeks Academic Partners for Smallsat Technology Collaboration

NASA is seeking small spacecraft technology project proposals from U.S. colleges and universities that would like to collaborate with agency researchers.

Small spacecraft, or smallsats, represent a growing field of space research and operations in which universities often have led the way in technology development. Smallsats, some of which are as small as a four-inch cube, are not expected to replace conventional spacecraft, but sometimes can provide an alternative to larger, more costly spacecraft. Smallsats can serve as platforms for rapid technology testing or specialized scientific research and exploration not otherwise possible. Smallsats also can be developed relatively quickly and inexpensively, and can share a ride to orbit with larger spacecraft.
