Pedro,
This is great, muchas gracias! One question, however - are the "past
passes" historical values "locked in time", or are they "back calculated"
from current keps?

I bought a set of egg beaters recently and they seem ok for anything higher
than 20 degrees. I'm looking to build a moxon variation

some free time.

Hi Roy,
THANKS! for nice & rewarding comment on new calendar facility on
http://amsat.org.ar/pass
The past & future passes where a date can be selected are calculated
on the fly using as you wisely said from current keps. However if a
much further/previous date (over three months) is selected calculation
will have a minor difference with actual, given keps changes over
time.
Have a good time and enjoy the birds.

>>> 7 DEGREES RX via EggBeater <<<
N6DAN-1 gets APRS packets on 145.825 MHz as low as 7 degrees via the EBB144.
See Tweet of report:
https://twitter.com/MachaleRobert/status/1124763800865873920
I asked him to leave the EBB on the N6DAN-1 iGate for the entire month of
May to get performance metrics. He also has a directional antenna for
N6DAN-2.
For the pSat, you can monitor the TX and RX angles here:

Not disputing the utility of egg beaters, but fwiw the ISS is the most
powerful ham transponder we have. The Ericsson is speced at 4 or 5 watts.
