30 years ago a company in Bombay, Jetking I think, brought out a printed circuit board for a general coverage radio receiver, called an L-board because of the shape of the PCB.

I couldn't find the board anymore in the market, nor can I find the design. I don't have any copies of the one I had. What is the modern equivalent if I want to hand over these boards to interested people?

I don't have a spectrum analyzer. I don't have an oscilloscope either. Hope to get one at some point. Yes, the local oscillator on my radio is based on the Si5351 chip. You could use either an analog one or digital ones (DDS chips are pretty cheap and widely available these days).

There is a used Icom 7300 available locally. It is a great radio.

But I am more inclined to to tinker with my own equipment. That is the small corner of the hobby that attracts me to amateur radio -- building simple equipment and test gear on our own and learning in the process and sharing our learning.

@neil
Yes, I agree with your sentiment. For me, the real community feeling had been in certain Free Software communities (like Debian project) and in the amateur radio community. People have come from far away to meet me in person when I travel and that is a feeling that needs to be experienced. *Goose bumps*

Trying to get back to amateur radio by building a uBitx radio. Antenna currently is a long wire.

അയ്യോ, മാപ്പൊന്നും പറയണ്ട.

പരിചയപ്പെട്ടത് വളരെ സന്തോഷം.

ഞാൻ ഒരു മലയാളി ആണ്. നാട്ടിൽ കൊച്ചി ആണ് സ്ഥലം. ഇപ്പൊൾ (കഴിഞ്ഞ ഇരുപത് കൊല്ലമായി) ജീവിക്കാൻ വേണ്ടി ബാംഗ്ലൂരിൽ താമസിക്കുന്നു. എല്ലാ മാസവും കൊച്ചിയിൽ വരാറുണ്ട്.

@akhilan
ആകാംഷയോടെ കാത്തിരിക്കുന്നു.

I think this little shell script is a game changer for getting ghc and haskell goodness into the hands of more people: github.com/haskell/ghcup

I'll be doing another #haskell live coding session soon. What language extension do you want to see me struggle with this time?

Thanks, that was a really well researched and we'll written article.

RIP Norm Hardy, brain behind much of our understanding of object capabilities.

Their website is still up, lots to learn from: cap-lore.com/ cap-lore.com/CapTheory/

@demonshreder
I think one reason is that it's implementation is non standard. Perhaps C++ raii is a better idea, however that is C++, not C. I think I am finding myself leaning towards a subset of C++ that improves on C for things I currently use C for.
