Re: [Elecraft] KX3: transverter schematic?

[Edward R Cole]

If anyone did not guess I made a typo, below (apparently fingers had 
see too many posts about the KX2).


==snip
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.
==

Of course I meant that ..."the KX3-2M is very different 
architecture.  It converts

144-148 to 50-54 MHz unlike other Elecraft transverters that convert
to 28-30 MHz."

Re: [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.

Re: [Elecraft] KX3: transverter schematic? I have it!

[David Anderson via Elecraft]

Thanks to a kind person on this list, I have a copy of the schematic for the 
KX3 2m transverter. It is the one I recall, but have no idea where I saw it 
before. 

Please don't ask me for a copy as I don't know the status of this and don't 
want to get into any trouble with party.

I am not thinking of copying it by the way! -  I just ordered the 4m version 
and am arming myself with as much info as I can before it arrives.

Re: [Elecraft] KX3: transverter schematic?

[David Anderson via Elecraft]

Sorry Ken,

It is a completely different design, I know that much. For a start it is credit 
card sized and it takes the LO from the KX3 not a built in Xtal Osc. 

I may have imagined seeing the schematic or detailed block diagram in some 
presentation, but there appears to be nothing on the Elecraft site, and no 
schematic in the downloadable manual for the transverter, though it does give a 
brief written explanation of the transverter.

I am surprised that a schematic isn't included with the transverter actually.

[Elecraft] KX3: transverter schematic?

Is there a schematic diagram for the KX3 internal transverter series available? 

I was sure I had seen one at some point in the past, perhaps it was in some 
slide show by Elecraft when they introduced it, but I can't locate it now.
