got another image

blueblur121 · July 11, 2014, 05:07:13 PM

Great. So where are those images supposed to go?

this is actually really cool, keep it up

Build a more relieable antenna, those images are all half corrupted

he said that his current antenna is just a placeholder until he can build one with better gain or w/e

the reason they're corrupted is because I have to remember to correct for the doppler effect and turn the antenna manually

the antenna I'm going to be building next is a QHF and it's omnidirectional so I won't have to run outside and turn it to correct the signal loss.

also NOAA-15 just passed above

also a really crap picture of the east coast woo

The doppler effect really causes all that distortion? I would think it wouldn't affect these kind of radio signals..

No it's just I have to do two things at once
Change the frequency and move the antenna for the highest gain

more pics pls

Legodude77 · July 13, 2014, 10:31:21 AM

That's really cool. Maybe you could post instructions/parts list on how to build one?

Twerky · July 13, 2014, 12:48:13 PM

I don't know what any of this means but it looks pretty cool.

all you need to know about software defined radio(that rimes wot)
http://rtlsdr.org/
I have a micro R820T: http://www.adafruit.com/products/1497
the rest of the things are pretty straightforward: wood, copper wire(can be steel or iron), some rg6 coaxial cable, an rg6 to mcx adapter and a 75 ohms coax transformer.

more pics pls

it's been rainy, I'm getting bad reception

but, I will try more satellites soon
