Hello Piraja and all
Congratulations, a great feat!.. I also am looking forward to a edge to edge QSO with PA1TNO in JO22li from CN87wk. If ever successful it would be 7837km. The allotted time is around 25 seconds I think though to be successful I might have to increase the height of my satellite array to 50 feet. This is divorce height, so efforts will be made at the 18 foot level. 73 Bob W7LRD Seattle. Wa.

We keep the QSO with a small window that the AO-7 has provided us. The window was only about 34 sec, this time interval we could not match any commit error. The distance between the two stations is 4085 miles or 7669 Km. Andre wrote via email: " "My Doppler calc was also gratefully spot on. For example I calculated that I should call so that my downlink is on 145.944.2 mhz I worked out that our Doppler difference would be 3.8 khz and amazing that was spot-on. There is really no time to tune !" Andre is right the time was too little for adjustments. Taking also into account that I manually worked the rotor and control of my rig.
