4m QRP transverter

It is some years since I was active on 4m.  Several years ago now, I designed and built this transverter as I had no gear for this band. I worked a few stations in a 4m contest with it and just a wire dipole.

Of course, these days the IC7300 from ICOM covers 4m.  These days there are lots of EU countries on the band, so it can be good in the Es season.

Years before I recall working ZB2VHF with 4W of AM in my university days by Es.

At some point I intend to get on 4m again.
