Re-purposing old Dish TV dish for GOES ?

Has anyone re-purposed a Dish TV antenna to receive GOES satellites? I've got one (including the feed horns) left from when I cancelled my service. I searched the interwebs and wasn't able to find any reference... successful or not. Any other RF uses, (including ham radio) ?

Side story. They wanted me to remove the feeds and send them back. I told them there was no way I'm climbing on my roof to do their job. Also told them I would dispute any charge that appeared on my card if they charged me for them. Actually, I had no problems with going up and disconnecting it but was p/o'd they couldn't send out a tech to do it.

Tracking Noise Generator with a Raspberry pi?

It is well known that a Raspberry pi can be used to transmit radio signals with rpitx. Does anyone know if you could use a raspberry pi as a tracking noise generator to characterize filters and such?

Spyserver (SDR#) support for Hackrf

Is there any way to connect a remote hackrf device to SDR# through a network ? I know the spyserver solution for airspy and rtl dongles but haven't found anything similar for the Hackrf.

Raspberry Pi, Dish Slimline, RTL-SDR, and Octagon LNB for 12GHz observations

Hey everybody!

I'm trying to make a radio telescope. I've posted two videos showing the build progress.

First: https://www.youtube.com/watch?v=nBS96eeNwCI

Second: https://www.youtube.com/watch?v=l0sdw2E1jz0

I'm thinking that the first thing I'll do with it is make some drift scans of the sun and moon. I might also try to pickup beacons from geostationary satellites. Anyone know of a list of ku band satellite beacon frequencies and their locations?

Thanks,

-Hunter

More things to do with an SDR?

Hello.

Was wondering if people had some suggestions for some new things I could do with my RTL-SDR, preferably things that will work just using the dipole kit it came with. (Just started a new job so its going to be a week or two before I can get paid and can afford to build/buy some radio gear).

Things I've done already: -Listen to airband -Receive NOAA signals -Receive and decode Pager data -Listen to FM

If theres something I can build using basic parts I might be able to do it with parts from my junk bin, but thats about all I've got for the moment.

Thanks

I made an animation that shows how the vertical gain pattern of a 2m yagi changes as it is tilted upward (from 25deg down to 50deg up @ 15 feet high)

QHF or Dipole for NOAA satellites

Hi all, I’ve been lurking here for a while but never really done anything involving this stuff before. Everyone’s been posting weather satellite pictures recently and I got this sudden urge to try it out so I’ve been looking in to what I need.

My question is what kind of antenna should I use?

I know it needs to be tuned to 137MHz and there’s two main types of antennas I’ve seen - the QHF helix looking one and a dipole one that has 4 dipoles at ~30 degree angles.

I was going to go with the QHF antenna as it seemed easier to build, but watching videos online some people were saying they had difficulty using a QHF and had much better results on the dipole type.

Any help or suggestions are appreciated, Thanks!
