[Elecraft] KX3: transverter schematic?

[Edward R Cole]

the 2m transverter is different than the K3 - yeah, since the K3 does 
not operate on 2m.  I suppose you meant the K144XV transverter 
installed internal to the K3.

Answer is the KX2-2M is very different architecture.  It converts 
144-148 to 50-54 MHz unlike other Elecraft transverters that convert 
to 28-30 MHz.

I found that I have the KX3 schematic but not the 2M transverter 
schematic.  I have the block diagram somewhere (I think).  It was up 
on the Elecraft website when the transverter was introduced but don't 
think you will find it now.

But really I can't see why one would need to have the schematic as 
the density of component on the pc board is not reparable by most 
hams.  This is one thing one should just send back to 
Elecraft.  David has his own reasons and I will not ask.

I once considered whether an ext. LO synth could be used and found 
out from Wayne how different the design was.  Temp compensation plus 
heat sink mostly took care of frequency stability issues for 
HF/6m.  I've not tested 2m for drift; running under 3w probably does 
not produce much heat.

I'm betting the 2 m XVRTER for the KX3 is different circuit than the 
internal one for the K3. It's also a very different form factor.
