Just a note that AO-7 has been reliably in Mode B for the past several days. For the past several months, AO-7 has had a tendency to flip from Mode B to Mode A even in the presence of only modest uplink signals, likely due to poor illumination on the solar panels. As the seasons have progressed, it appears that the illumination situation has improved. Get on and make some QSOs! This would be a particularly good time to set up skeds for extreme range QSOs.
According to DK3WN's illum software, from October 15th through November 21st, AO-7 will be in constant sunlight. During this period, the 24 hour timer will function and the satellite will spend 24 hours in Mode B then 24 hours in Mode A. Get those 10 meter antennas ready!

Sounds good! I've got the radios for possible CW QSO on Mode A. If anyone has done CW on AO-7 Mode A, do you have any pointers? Any particular part of the bandwidth where CW ops hangout?

Hi Steve,
Hope to hear you on Mode A CW. I have made some CW QSOs on Mode A. Most stations seem to hang out around the middle of the passband. That is 29.450 on the downlink. I think it is 145.900 on the up link but I might be wrong. Also remember than in Mode A, AO7 is NON-INVERTING, so increasing your uplink frequency will also increase the frequency you come back to earth on.
