In this day and age, any "picture" you get to see, should be considered "art
work" unless you were there to see the event. Reality is only a moment, not
something you can experience in the future.

It can but, in the days of all the satellites having analogue/linear
transponders, where one excessively strong signal would hit the transponder
AGC and knock out the weaker stations, we had one day a week (I believe
Wednesdays) where all but genuine QRP startions (did we say 10W ERP?)
were asked to keep off the birds.

There was a problem changing to FM operation on the L uplink to the second
repeater on AO-51 last night.
That problem was corrected on the 1345Z pass this morning and the second
repeater is in mode L/U FM and is now working fine.
Enjoy this mode the rest of the week.

Hi all,
AO-51 is working very well in mode-L/U FM.
On the two last passes here over Copenhagen [Denmark :-)]
The signals on the uplink went through the "transponder"
with nice downlink signal.
There is some slow fading, QSB, on the uplink when the satellite
turns. That can not be avoided - but if you keep talking
your signal will come up again.
Remember that the downlink on 435.150 MHz is left hand circular.
I use an IC-910H with 10 W on 23 cm.
Antennas are two 19 turn helixes - gain about 18 dBi, right hand
circular.
Cable loss like 4 dB to the antennas from the transceiver.
Another observation is that it helped to use the compressor
in the IC-910.
Managed to get a resonable downlink signal when the distance
was about 3200 km.
Have fun.
