Why can't Icom do this?


I've been critical of my IC-7610 and the lack of audio spectrum display centred around the CW pitch frequency - the Kenwood 890 has it.

I recently came accross a design in Practical Electronics for a simple audio spectrum analyser and decided to build one as an experiment. The DSP chip cost less than 3 GBP.

I wonder why Icom can't do this?

The old and the new


Whilst rummaging in the attic looking for something, I stumbled accross this old Direct Conversion receiver I built when I was a young whipper snapper. This is a design by Drew Diamond, VK3XU and is published a the G-QRP club book called "Radio projects Vol 1".

I did a video for my YouTube channel having a look back at my construction capabilities from all those years ago:

I hope you enjoy!

Funny old World


I've been having an e-mail exchange with a Radio Amateur in New Zealand - he has been trying to get one of my YouTube projects based on the STM32 blue pill boards to work.

Following a few emails back and forth, he sent me this:

which is nice :-)

My latest ramblings on YouTube are all about the classic Sudden HF receiver, you should check it out!

Fun, don't you think?
