Robert, NH7WN: Shortly thereafter I heard CW at a speed similar to COMPASS on frequency 437.305 MHz. For a short time I tracked Celestrak's OBJECT A2010:020A at 17 deg. maximum elevation AOS from the west tracking slightly to the SE. The signal was fading severely and I was unable to make any reasonable copy. Characters I did hear appeared to be:
1... (numbers) DDEFE0 EG CO/710

Very difficult with D700 (FM/Fades and 5 KHz steps in Doppler!!!): BUT something was there where Celestrak said OBJ. A would be !! No packets heard: Only CW. Time 2051Z; azimuth 224 deg at 17 degs elevation

On May 29, 2010 I made an exciting experiment together with my friend Tetsu san JA0CAW. Since we can not hear NEGAI* in Central Europe we established a live link between our stations. Tetsu gave me access to his PC via remote control (VNC) and I could control his transceiver. We established a second connection via skype for audio.

The audio quality was excellent and I could hear NEGAI at a 10 deg pass over the Pacific Ocean. Thank you Tetsu san.
