John described RFI from the wall wart switching supply and such supplies
are both notorious RFI generators and are ubiquitous. Our DirecTV
receiver/DVR is completely quiet on HF and as far as I can test, on VHF
and UHF as well. I've never interfered with it on any band, even when I
was running 1200 watts.
Regarding satellite internet, the unmanned spaceship is about 38,600 km
away in the southern sky, so there is a significant LOS delay on top of
all the usual processing and routing delays. This can make most forms of
remote control problematic. We had a neighbor who worked for HP, often
at home via a VPN, and the satellite internet did not work for him.
You might see if there is a local wireless provider. I hosted a couple
of RAP's for the local provider when we lived in rural NorCal and got
free, 50 Mbps both ways in return. Unfortunately, such service is
usually unavailable in more densely populated areas where cable and DSL
is available.
Really heavy rain will kill the satellite signal [Ku-band, I think] as
will snow on the feed horns and in the dish. I can get to our dish from
the ground with a broom. If you live in an area with significant snow,
you might want to make sure the dish is accessible. I've wondered about
some heating tape on the back of the dish but haven't done anything yet.

Hi Reed
YES ! DirecTV receivers are horrible racket makers.
#1 I built a new power cord for the receivers wired into a 12V ASTRON regulated
12v supply. No More Switcher Wall Warts allowed at my QTH.
#2 The HDMI cable from the Rcvr to the TV set has 12 turns through a stack of
TWO of the 2.4" diameter Ferrite #31 mix cores.
Several other 12v devices are also connected to that same Astron supply.
Modem, Router etc. Now that rcvr is quiet.

Has anyone had trouble with RFI, receive or transmit, with Dish or
Direct TV. I have cable through Comcast & tired of their rate increases
so thought I give satellite a try since looks like more bang for the buck.
Thanks,
Reed W4JZ
