NOAA Satellites Pt 4

The very first composite image I made of the satellite passes on 20 Feb 2017 between 6:30 and 8:30 am.

Felt like adding even more complexity to my NOAA satellite system: Composite images.

At the moment I’m just putting the following code into my render computer:

wxproj -p cylindrical /tmp/$image /tmp/$proj

And then manually aligning everything in GIMP with moderate success.

Flex 3000



So I’ve been putting off this post for a bit just because I don’t have a lot to say.

As I was looking at buying an IC-7300 or TS-590SG in the near future, getting a fully featured 100W SDR for significantly less was just too good an opportunity to give up.

Note to self: EFJohnson 5100

A helpful member of /r/amateurradio has mentioned the EFJohnson 5100 as a cheap used P25 Phase 2 radio. Well looking at costs on ebay that is certainly true. Wow.

Then looking around I found this post by user “wildcat” on about a P25 UHF ham repeater, VA7LNK/R.

There is one UHF P25 ham repeater located on Burnaby Mountain which covers the Greater Vancouver metro area. The repeater is configured in mixed mode. Not much activity on there in the last few years, many have moved to other modes like DMR.

T110.9 / NAC293

Well I’m now quite tempted to give this whole thing a try. But its December so I’m already spending $$dosh$$ on other people.

NOAA Satellites Pt 1


Mind the cable.

Haven’t made a post in a while, thought I’d do something about that.

So I’ve recently got back into dabbling with NOAA satellites, to that end I’ve setup a test antenna in my bedroom. Initially I was running a Cat5 network cable to it since I wanted to stream I/Q data to my PC and decode there, but it made having to leave my room a bit of a chore so away went that plan. The new plan is to perform everything locally on the Pi itself.
