Hello Mike,

Happy New Year to you, and I hope that Father Christmas was good to you!

Forgive my ignorance, but what is the K3 H Mode mixer, and which type of
switches does it use?

I have been using H Mode mixers in my homebrewed receivers since 1994 with
useful results.  For example my most recent effort (2008) yields a IMDDR3 of
120 db at 1 kHz spacing, and 112 db inside the passband, when using a 500 Hz
Quadrature roofing filter followed by a "strong" IF/ audio system.

I left Scotland in July 2011, and am now living in Luxembourg.

73,

Geoff
