The sun orbiting the earth, spectrum analyzers and the uBITX

Hi,

I was reading something on the history of astronomy and an amusing thought came to mind. 

If it weren't for early astronomers banging their heads against the wall trying to explain the complex cyclic paths of the planets orbiting around the earth we may have not been gifted some amazing math. This provided to foundation for developing fourier analysis and likely the calculus. (and a way to discover/prove the original assumption was wrong.)

And because of the birthing issues of the uBITX and so many people interested in finding ways to improve it, so many of us are vastly improving our working knowledge of various parts of RF, radios, software and electronics.

Indeed its a nice enough assemble a radio experience for hams around the world. Its issues are sufficiently addressable. Here I was struggling in installing Gordon's external relay board,  only because I didn't understand its interfaces. Finally it's working,  to address the harmonic spurious. I have the simple v5 version of the 45 MHz filter installed in the transmit path. I may not have it measured for a while, but these should be improved. Moving back to evaluating simple agc solutions,  and supporting those in my local club build.

Ours may be more called 'Learning by Tinkering' :), which involves some but not that much thinking, luckily enough!

My take on the Sun orbiting system (Ptolemaic) is ya gotta give the guy credit.  Based on this concept and some magic algorithms the ancients managed to predict , so they say,  eclipses, rising times of planets and all sorts of cosmic ephemera.  I suspect that they predictions would get well out of wack after a year or two as they must have been the equivalent of binomial expansions ... sort of vaguely linearising stuff to theories that were flawed. ...

.Now is the Ubitx the Ptolemaic system and the  xiegu 108g the  uBitx after a modern day Issac Newton has fooled with it.?. perhaps that is the question that will get me zip tied and run out of town :-) .. backwards on a hoss..

Yes, it is amazing how far they got with the wrong planetary system.

I guess what I'm saying is, the struggle our forefathers were having to work out the kinks in (for example) the planetary model of the time, led to amazing increases in knowledge as they worked things out.  

If the uBITX had been perfect from the start we might be happily talking away and our knowledge advanced to just where the knobs are and how to connect the antenna coax connector. But, because there are things about the uBITX that beg to be improved, we started working on solutions and are increasing our knowledge in the process; either by our own experiments or reading what the others on the group try and either succeed or not. 

So (within limits) working with things with imperfections or kinks can lead to an adventure of learning that something that goes really smoothly may not provide. Because of the happenstance of buying the uBITX with it's current kinks, I've been launched into learning more than if the uBITX had just been a hook up a microphone and talk situation. Certainly nowhere, anywhere near a Newton or Kepler, but I'm happy for the modest level learning the uBITX has brought about.

Absolutely, I am very happy with these solvable imperfections. At the beginning I thought it was like solving a partial differential solution without solution at all. I was wrong, the beauty of the uBitx resides in its multiple solutions.

Ahh Tom, I definitely felt this way when joining this group. I’ve learning so much from tinkering with the uBitx and this group, it’s effected how I now see things around me. It’s like someone turned the lights on. 

Thanks uBitx!!
