Hi Dave, Nader,
A CubeSat Converter is certainly an interesting thought.? In addition to
the challenges (that's the hip cop-out from saying "problem" these days)
that you noted, I'm thinking that the ConverterSat would also:
Have to be in the footprint of Es'hail
So as a converter even only in the footprint for stations in the
footprint but w/o the S and X equipment, it would only offer a 10-20
minute window to Es'hail the usual 3-6 times per day
In trying to extend the footprint, it would need to be of a pretty high
altitude itself in order to extend the footprint by much
Being on the edge of the Es'hail footprint in order to extend it,
requires more power/gain/pointing to connect with Es'hail
But I guess these are more "usefulness" challenges than the RF
challenges of acting as the converter you have listed.
It gave me thoughts about GOLF-TEE trying to bridge the gap, but would
have design implications as you noted that at least wouldn't be possible
in our current timeline.

I would make more sense to me, in my humble unbiased opinion,
to have someone in the footprint of Es'hail to put together
a ground station that that is also an EchoLink node. That
way, anyone in the world could potentially access Es'hail
via EchoLink.? It would be an interesting exercise, anyway.

Hey Mac,
I like that very much! Let's do a SatNogs reverse. One or more station
within the footprint that folks around the world can use to connect to
Eshail.

Not that experienced with satellite operation, so I?m hoping someone can
fill me in. What would be the advantage of the Arrow 437 X 14 antenna be
over their standard antenna with 7 elements on 437?
I?m considering it for fixed station use?not portable.

What would it cost to put together a ground station?
Perhaps a little crowd sourcing (cash/hardware) could
get one built and dedicated to the task.

Hi,
Our new warehouse can now capture and store data for:
funcube1
nayif-1
jy1sat
eseo
I'm currently working on the user interface to give it all the features of
the existing warehouse but our priority
is for LEOPS (realtime data) support for JY1Sat and ESEO.
If you can spare a few packets from funcube1 and nayif-1 it should be
appreciated.
As part of the transition the URL for the FUNcube dashboard and viewing the

Please make a note of your existing URL when you switch back.
As always, many thanks for your support.

*WATCH LIVE: ES'HAIL-2 MISSION*
SpaceX is targeting launch of the Es?hail-2 satellite on Thursday, November
15 from Launch Complex 39A (LC-39A) at NASA?s Kennedy Space Center in
Florida. The primary launch window opens at 3:46 p.m. EST, or 20:46 UTC,
and closes at 5:29 p.m. EST, or 22:29 UTC. The satellite will be deployed
to a geostationary transfer orbit (GTO) approximately 32 minutes after
liftoff. A backup launch window opens on Friday, November 16 at 3:48 p.m.
EST, or 20:48 UTC, and closes at 5:29 p.m. EST, or 22:29 UTC.
Falcon 9?s first stage for the Es?hail-2 mission previously supported the
Telstar 19 VANTAGE mission in July 2018. Following stage separation, SpaceX
will attempt to land Falcon 9?s first stage on the ?Of Course I Still Love
You? droneship, which will be stationed in the Atlantic Ocean. To watch the
launch live or learn more about the mission, visit www.spacex.com/webcast.

Les,
Advantage:
Lower transmit power (because it has more gain), but the birds require such
low power as it is with a yagi, that it is not important in the lower USA
Disadvantage:
Harder to stay on bird (tracking), because its pattern is narrower (that's
where the gain comes from)
If you have a clear view of the sky and no obstructions:
I'd stay with the standard size if you have 2.5 or 5 w output from your
radio.
If you have obstructions, then more gain might help on rx, and certainly
will help "some" on tx, but once you hit foliage or the house...your 70cm
uplink signal will be greatly attenuated and there is little you can do
about it.
I run eggbeaters (omni antenna with very little gain) and am being heard
quite easily when the house doesn't get in the way, or there isn't thick
foliage .
All these comments are predicated on 70 cm uplink and 2m downlink. The
obstruction losses are MUCH less on the 2m downlink than on the 70 cm
uplink.

Great launch so far with a successful 1st stage recovery and the 2nd
stage in a coast orbit until the second firing.
