GAP 20m Monogap Vertical Dipole Review

I’ve been setting up a small trailer for use as a mobile, independently powered radio station for use at HF and VHF. To that end, it has its own deployable solar panels, internal power storage, and dedicated power conversion electronics. There are quite a few 12.6 VDC VHF and HF radios out there, and I own several, so the radios are less of a problem than a situation where I have to make some kind of fun decision between multiple good options.

VHF antennas are no problem. But the HF antenna… There’s the rub. If it’s to be truly portable, that means it cannot be large, and it will not be high in the air. Those are very significant drawbacks for most antenna systems; they directly impact both receive and transmit performace. So I went hunting. Eventually, I happened upon the Monogap 20 meter antenna, which is a vertical dipole; easily portable within the frame of reference of what can be safely transported in the bed of my pickup, light, easily mounted and unmounted, inexpensive, and — as it turns out — a surprisingly good performer.

ICOM IC 7300 Transceiver Review

The

IC-7300

IC-7300

ICOM IC 7300 marks an important inflection point for the “big three” amateur radio manufacturers: The beginning of true software-defined RF processing from one end to the other.

As the first full SDR transceiver from “the big guys”, it is interesting to consider the price point, feature set, and performance both in light of the legacy analog designs, and as compared to what SDRs are known to be capable of.

aa_counter.py — pre- and post-increment and decrement in python

Screen shot 2015-05-24 at 3.36.42 PMI like Python. A lot. But it has its limits, and short of forking a new version of Python for myself, sometimes it is just best to implement some kind of work-around. In this case, for pre- and post increment and decrement operations on counters, which Python regrettably lacks.

aa_bargraph.py — Bar graphing using text and image-free HTML

Need to graph something? Happens to me all the time. And I need some very particular functionality. But that doesn’t mean I want to code it up every time I need it, nor should you have to. Python’s import library mechanism makes “canning” nearly any functionality you can imagine easy to do, and once canned… well, you know the drill. Import libraries are wonderful.

Console (text) mode bar graph in XTerm shell

So in this case, it was bar graphs I needed. Sometimes at the console, sometimes on web pages. aa_bargraph.py puts that together and makes it usable at several different levels of sophistication, at both the console (in text mode) and within the context of an HTML web page.

Amazon Echo really, really needs this feature

What if it was easy to make Amazon’s Echo do anything your computer knows about, or you can make it know about? That’s what I’m going to talk about here.

It’ll be worth your time, I promise.

The Echo is a nice device to have around the house; you can ask it some things that Amazon has set up, you can even launch a few (very few) things via the IFTTT website. But there is a huge, untapped area there, those things that are unique to you and your family.

What if you could leverage the Echo to do… anything!?!?

A Theory of Mind

Consciousness and the mechanism of thinking in general have remained an opaque block to science overall and specifically to researchers in the area. Here I attempt to lay out the fundamental underpinnings that support consciousness, as well as other related mental activity, and then place consciousness and related function into the context so established. I make a concerted effort not to lapse into jargon.

About the Title

As it turns out, “Theory of Mind” has some previous associations, so please note it was only intended as a description of the content here, not a declaration of association with these ideas.

I will present a description of how the brain operates. Not a metaphor — metaphors tell you what things are like, not what they are — but my conclusion as to how the brain, and therefore the mind, actually works.

I’m working backwards on this, as are we all — but after almost forty years of examining the problem I have come up with a model that has turned out to satisfy every question that I have about thought and consciousness in what I can only describe as a manner satisfactory to myself. Which is, I think, in itself notable. If for no other reason than everything I have ever come up with previously, or read about, has utterly failed to do so. So, dear reader, please come along as I try to explain myself. Literally.

SdrDx breaks 10,000 users

I’m happy — kind of delirious, actually — to announce that the number of SdrDx installations has broken ten thousand as of Friday, June 6th, 2014. This number comes from counting the number of different IP’s of actually running SdrDx instances. The break down as of this evening is 6186 OSX installations, and 3865 Windows installations.

Now, this is not the same as a count of active SdrDx users, but it is a vey good estimate of the number who have actually tried out the program.

Thanks to everyone for surprising me with an unprecedented level of interest in this project. I appreciate it a great deal!
