Mak, You're absolutely right ... the satellite *DID* start in mode-C but changed to mode-B when it came further into the sunlight ... the satellite has been running along the grey line at certain times on certain passes ... not really in eclipse and not completely in sunlight.

This of course affects the transponder.

I *PURPOSELY* made my own entries as mode-B yesterday so as not to completely confuse the newcomer in case he or she has been reading some of the comments on the various pages regarding AO-7 eclipse and modes information.

To understand what is going on with AO-7 one has to read the *ENTIRE* history ... and most people don't do that ... they just assume that if "Joe Bloggs" says it's so and so ... it *MUST* be true ... (which it more often than not isn't!).

John, forget it. I have already corrected it to Mode-B.

It should be very big puzzle if we starting Mode-B & C.

BTW Mika he didn't entry me on Log, I don't know why, the QSO was completed... I deleted also him !

However also the next pass was very weak. Difficult to copy myself on CW.

Hi John,

today afternoon during the usual AO-7's "good" pass for me, over W.Asia - E.Europe, I was wondering where is the Satellite! Nothing till 25 deg. Elevation, but after a carefully listening on Downlink I heard my CQ-CQ signal, very-very weak. After 2-3 mins, Mika OH8MBN he answered me. For first time it was difficult to copy both signals (Mika's and mine). A very strange ECHO also took place, it was also very difficult the Zero-Beat. BTW I didn't hear any other on this pass.

If my receiver and my antenna are both in good shape, I wonder: was it "Mode-C" ?

My entry in Emily's LOg is as Mode-C. If I am wrong, please correct it.

73, Mak
