Hi all, It works great.
Thanks to Nigel for the new keps for Object A:
XW-1 1 36121U 09072A 09349.53641119 -.00000045 00000-0 00000+0 0 31 2 36121 100.5050 046.6267 0007989 035.4736 324.6735 13.16391085 50
I changed the name from Object A to XW-1 :-)
It works on SatPC32 and NOVA for Windows.
On the pass with AOS at 16:45:50 UTC here in Copenhagen the tone did not change (to my old ears) over the whole pass.
Used 435.789400 MHz as the center frequency on the IC-910 in USB. The usual ICOM offset in USB.
Nice 20 minute passes and long range. Looking forward to the transponders. 73 OZ1MY Ib
Hi All,
To day December 15 signals from the satellite XW-1 CW beacon during Rev 9 changing into Rev 10 over Europe were very strong and clear with only a beacon power of 65 mW into a satellite TX antenna RHCP with gain of 3.0 dBic
The satellite from AOS at 20:12 UTC and LOS at 20:34 UTC was into the eclipse (ECL) all the time.
My receiving condition was a 12 dBic RHCP 10 turns Helix antenna with a low noise preamplifier antenna mounted NF=0.45 dB and Gain G = 20 dB
I was using a 434-436 / 28-30 MHz downconverter in the shack connected to a HF Drake receiver R4-C tuned to the 10 meters IF interposing in between a 20 dB attenuator with 1 dB steps
The XW-1 beacon was very constant in signal strenght fading very slowly changing between 20 dB to 15 dB over the noise floor in about 30 seconds as measured with the 1 dB step attenuator connected into the 28-30 MHz IF of my receiving system.
The same was experienced during the following Rev 10 changing into Rev 11 over Europe with AOS at 22:06 UTC and LOS at 22:18 UTC with the satellite in Eclipse (ECL) all the time.
During the above orbit the Elevation from my QTH in JN70ES was only 8 degrees maximum over the free horizon with no obstructions in direction of the see.
The following keplerian elements as given by Nigel G8IFF for object A are extremely correct because I losted the signal over the free horizon just at elevation of - 0.2 degrees as computed by InstantTrack
XW-1 1 36121U 09072A 09349.53641119 -.00000045 00000-0 00000+0 0 31 2 36121 100.5050 046.6267 0007989 035.4736 324.6735 13.16391085 50
That's all for now
I hope that very soon the linear transponder will be open for general use and stay in SSB/CW as long as possible for the benefit of many users at the same time.
