Another great design, I am using the BITX20 transceiver.

Are you going to build the minima? I like the concept: arduino plus SI570, I might give it a try!

Hello Joop

I'm on the Minima mailing list and awaiting  the first test results.
It looks promising !

Have fun

It looks a whole lot like a Bitx with a FET first mixer and DDS VFO.  I built a Bitx with a DDS VFO and a 10 MHz IF.  The best thing about a 10MHz IF is that I didn't need a clock to know what time to put in the log.

I give up!! I'm impressed but getting way too old for this sort of thing.

Spark transmitters are beginning to look good!!  ;D
