My Excitement goes from up and up
andrew....@googlemail.com
With Ted Cline’s amazing help, I have truly gone from zero to hero in 4 months!!!
Last night, we spent 4 hours on a Zoom call in which he gave me a run down of the science on creating galactic rotation curves and then we used my data to produce plots to show that galactic rotation (I can’t believe I could see this in my own data!!!) does NOT follow Keplarian rotation!.......The smoking gun evidence for dark matter – demonstrated on my own tiny radio telescope in my backyard! Wow! Wow! Wow!
When I started this exercise, I was hoping to pick up some galactic hydrogen – and was not certain I would ever achieved this – but now I have already mapped some of the arms of the Milky Way (my dream) and demonstrated dark matter (beyond any possible expectations I had)!!!
How did I do it:
(i) SARA’s Scope in a Box project.
(ii) Ted Cline’s wonderful ezRA software suite – why is everybody not using this? Perhaps everyone else wants to do it the hard way?!
(iii) Ted Cline himself. What a guy!
Now I am filling in gaps on my map and seeing how far I can stretch it across additional galactic longitudes.
Radio Astronomy is truly an amazing hobby!

My own software has focused on collection and preliminary analysis, and allowing a real-time display of "stuff". It is based on
Gnu Radio, which has historically been off-putting for Windows users. But I understand that Radioconda makes that a LOT
easier these days. The Radioconda installer -- designed by Ryan Volz at MIT Haystack really makes it a lot easier. I don't know
whether my most recent software--baa_seminar "just works" under Radio Conda, but maybe I'll poke Ryan to see if he can get
it working...
But I haven't focused much on "packaging" post-facto analysis, since there are so very many generic data-analysis packages
"out there". Granted, they each have their own learning curve.
I started "evangelizing" SDR applications for small-scale radio astronomy nearly 20 years ago, and TBH, it has only been in the
last 5-8 years that this community has started to think of this as anything other than "kooky". So, I'm heartened that folks
now actually have *choices* in the software they use for amateur and small-scale radio astronomy, including ezRA, my own
software, Virgo, etc, etc.

My apologies if my comments in any way appeared to criticise folks for doing things a different way - I did not mean that - they were only meant to emphasise just how amazing I think ezRA is!Andy

The fact that there are options is exciting, and I think that can be a big help in keeping people interested longer and encourage them to go deeper. I know Ted's Software has really kept me interested because I can "see" the results and shapes and some analysis relatively quickly. RA has a steep curve.
With the options now you can see the fruits of your efforts quicker, and get encouraged to dig deeper into the science. I know I'm already thinking about how to get better data to test the various theories on the amount of material in the Milky Way, as well as life after H1. Have a great group to talk with, and share knowledge with, makes a huge difference as well.
BTW, I was reading the rtl_sdr wiki to figure out how to do some specific testing on Linux and I ran across modules written by Marcus. Real street cred.
Gnu Radio applications in small-scale radio astronomy. I set it up a bit like a classroom exercise, and we built the application
together, sort of. Both of the videos are available on YouTube.

I'll note that the "baa_seminar" application is called that because it grew out of a two-part seminar I did for the BAA on

Thanks, Marcus.Please give us a link for the "baa_seminar" .GRC files ?

The "baa_seminar" software is at:

I need to write more documentation for folks who didn't "attend" the seminar. But I also need there to be two of me...
I think the 2 videos were posted as,
