Hi Wes, thanks for your note.
Yes, it is the second mixer that needs improvement. I have the mods on paper and we are waiting for a volunteer to lend us a K3 for some time ... this will need soldering work...hi I will keep you posted once tested 73 Gian I7SWX >________________________________ > Da: Wes Stewart <[email protected]> >A: "[email protected]" <[email protected]>; "[email protected]" ><[email protected]>; Giancarlo Moda <[email protected]> >Inviato: Venerdì 1 Marzo 2013 19:02 >Oggetto: Re: [Elecraft] K3 mods by I7SWX > > >It's the second mixer that needs improvement. > >Wes N7WS > >--- On Fri, 3/1/13, Giancarlo Moda <[email protected]> wrote: > > >>From: Giancarlo Moda <[email protected]> >>Subject: Re: [Elecraft] K3 mods by I7SWX >>To: "[email protected]" <[email protected]>, "[email protected]" >><[email protected]> >>Date: Friday, March 1, 2013, 10:18 AM >> >> >>Hi Milverton, >> >>I am not sure about your question, sorry. >> >>It is not a pitch to Elecraft, if I understand what you are asking for.

That pushed me to do a trial and I went ahead with my friend Sergio, IK8TNG. From what we thought interesting results we designed a swappable H-Mode Mixer and made it available assembled and tested to operators without the need to use a soldering iron.
