Orbitron Prediction Output - More than three lines?
by John Brier 08 May '15

08 May '15

You can select Brief or 3 lines (AOS, MET, LOS) but what I would like is a line for every minute or two during the pass, maybe selectable. Also, can I get directions instead of AZM? I haven't gotten used to that yet. All this would be very helpful to me instead of having to bring my laptop, which will be hard to see outside anyway. Something I can just print out, and look at my watch to know where it is, and where to point, would be more convenient, I think. PS, I got into SO-50 this morning and this evening, meaning I could hear myself clearly on the downlink. someone in a Delta grid square came back to me this morning, but I didn't have the bird well enough to receive very well and had to apologize for that. This evening I heard myself multiple times but everyone was trying to work W4T. I got a good audio recording of the evening pass too. If someone wants it, let me know. My next attempt at SO-50 will be the Thursday morning pass and the evening pass too perhaps if I don't get anything in the morning. I must say, working this bird is very hard with such a low power signal. It is still very fun, but I am definitely thinking about a preamp! Hah! 73, KG4AKV, Raleigh, NC, FM05

Probably FO-29 world distance record; QSO between US and UK
by Hector W5CBF/CO6CBF 08 May '15

08 May '15

Hello to all I am pleased to report that Peter G4DOL and I had another extreme QSO on FO-29. It is my furthest contact on the birds! Back on October 2013, Peter and I had a very nice contact between EL92sd, Cienfuegos, Cuba and IO80so, Weymouth area, UK. It was a 7286 km contact and probably the first contact between UK and Cuba on FO-29! Peter and I desired to try again on FO-29, this time between EM21hs, Texas, US and his habitual spot in IO80so. We were able to complete a very nice CW contact on the 92319 orbit of FO-29. Peter had just 0.1 degree as maxim elevation while I had 0.8 during the 80 seconds mutual window. As before, Peter did all the hard work by driving until his habitual spot at a cliff-top and setting up his "portable satellite station" (19 elements Yagi for 435MHz and 10 elements Yagi for 2m both with horizontal polarization). FO-29 was sounding really good on these orbits. It was a solid 559 satellite contact, we were very impressed. We made the calculations using our 10 digit grid squares at http://no.nonsense.ee/qth/map.html The distance between the stations was 7537.799 km (4683.77 mi). To my knowledge, the longest distance archived on FO-29 until now had been 7,533.685 km between Frank, K4FEG and Erich, DK1TB. http://www.qrz.com/db/k4feg It appears that an even longer distance is achievable. It has been reported that FO-29 has a "theoretical maximum range" of 7502 km, but I guess that at least 7600km is doable. We will try to break our own record! This contact was possible thanks to the great feature implemented on SatPC32 V12.8b. There is an option of seeing the frequency you are at the satellite receiver at any time during a pass. It allows the operators to tune the right frequencies and attempt a contact without having to search for each other. We have some pictures, recording and GPS screen shoots. I will try to post everything online. I will be happy to email everything, also. Thanks very much to Peter for his persistence, effort and all the fun! 73! Hector, W5CBF/CO6CBF

Probably FO-29 world distance record; QSO between US and UK ---follow-up
by Hector W5CBF/CO6CBF 08 May '15

08 May '15

Hi to all Just a quick follow-up on my earlier message about my QSO with Peter, G4DOL on FO-29. I received an email from Frank, K4FEG; He let me know He misprinted the distance of his contact in his QRZ web page. The correct distance of his contact is 7,538.685 km. He already fixed it in his web page. My contact with Peter is 886 m down their mark. You can see a couple of pictures and listen to the recording at http://amsat-uk.org/2015/05/06/uk-texas-extreme-dx-contact/ 73!

Satellite Demonstration Passes for Dayton Hamvention
by Keith Pugh 07 May '15

07 May '15

An Amateur Radio Satellite Demonstration Station will again be active at Dayton Hamvention this year on 15-17 May. I have included the planned schedule of passes below. Times are in UTC - you can convert it to your own time zone. I have also included this as a text file in case there are formatting problems. We plan to work as many of these passes as possible. Our station is outdoors so weather can give us problems and we only have a limited number of operators so - we will work as many as possible. I might also note that we do have obstructions due to vehicles in the parking lot and parts of the Hara Arena buildings from about 300 deg. through North and on around to about 70 deg. The plan only includes passes with peak elevations above 10 deg. Lower elevations of any of the passes may be obstructed - be patient. 73 - Keith, W5IU AMSAT DAYTON HAMVENTION DEMOS - 2015 TZ = UTC N 39.820328 W 84.255224 ELEV. 296 M MIN PEAK ELEV. = 10 DEG GRID = EM79ut * = Listen Only Pass - Telemetry, Doppler, Ant.
