Brain Surgery with a Rusty Spoon!

The English language is very rich in words, even just a few words, that convey a whole life story. That phrase in the title says just that. It represents a conundrum of views -- brain surgery highly delicate and done under a microscope and the tool of choice a rusty spoon, which is anything but high tech and borders on really crude.



That phrase translates very nicely to ham radio. Yesterday's and today's ARRL DX contest when approached with a boat anchor of the 1960's is no match for an SDR radio even one using I/Q versus DDC. The DSP is amazing in its ability to winnow the wheat from the chaff. Signals pop out from nowhere and that is the leverage needed to be a participant. 

I could surely hear them but with only 3 Watts PEP no match on 20M with the KW+ stations here in the US. But unlike the old analog rigs it is an easy fix to add a 100-watt amp to a rig that hears them. Getting on frequency is not that onerous.




I keep beating the drum but that is just the way the cow ate the cabbage. I know of some work being done by a radio club who is undertaking a group build SDR receiver project, and I heard the prototype -- all done with a really cheap MCU interfacing with a laptop running QUISK. Impressive and that likely will be leading to a companion transmitter to form a transceiver. Another factor all SMD and low-cost parts. Bottom line it is not just me beating the drum and the crew is moving forward.

Them that know can make it go.
