Video of my Barebones Superhet







I literally blew the dust off this thing last week.  I posted the schematic a few days ago (scroll down).   This morning I finished re-building the CW transmitter that went with it.   I am running out of rigs to re-build, so I suppose I will now have to start building some new ones.  Maybe a BITX-20?  Or a BITX-75/20?

    Bill - why not a G6LBQ multiband Bitx derivative?

    This will the winter 2013-2014 project for me!

    Nice receiver Bill! I like your coffee can tuning indicator. That is a great idea. I hope you have a safe and joyous Easter weekend.

    A nice simple superhet. For the beginner, as you show. If you build it in blocks it's easier to get working and make modifications.

    Do you have problems with using 3.579 MHz as an IF? Either the harmonics 14.318 MHz from the bfo. Or a stong signal on the IF frequency.

    All the very best
