Jupiter emissions are MHz. Ku band is GHz.

Good morning Brooke,
Sorry, don't know the answer to that question. Interesting question
though.
I am aware of the Radio Rove project and have played around at
"listening" for Jupiter on HF and LO VHF but not in a very serious way.
cheers, Graham ve3gtc

Hi Graham:
Do you know if anyone has used a Ku-band receiver, like described in
the paper, to look at Jupiter?
The Radio Jove project is looking between 18 and 40 MHz.

Exactly geosyncs have sun outages as the sun aligns with the sat
and your
dish.
GPS because the sats are distributed do not suffer from the effect.

I do not believe it has any effect. The DirecTV satellites are
geostationary at about 22K miles. I used to experience the same
phenomenon
in the late 70's with my TVRO receiver at C band. GPS has some 36
or so
satellites in a Medium Earth Orbit (MEO). Blockage, if it can even
occur
due to the nature of the receiving antenna, of a single one for a few
minutes will have no discernible effect in my opinion. 73 - Mike

Subject: [time-nuts] Sun Outage
Two days this week, there was a 3 or 4 minute outage on DirecTV as
the sun
aligned with the satellite and my dish. So I was wondering what
kind of
effect this has on the GPS system and especially timing receivers.
