K3 Transverter Control Cable

I'd like to make up a K3 Transverter control cable.

Which pins of the Elecraft Transverter J6 DB-9 connector
are connected to which pins of the K3 AUX I/O?

Bud,

The transverter cable needs only 3 signal lines plus ground.
AUXBUS K3 ACC pin 2 to KXVxx pin 6
KEYING K3 ACC pin 10 to KXVxx pin 9
+12 VDC K3 +12 volts output to KXVxx pin 8 (other methods can be used.
but the KXVxx uses this input to sense when the K3 has been turned on).
Ground K3 ACC pin 5 or 12 to KXVxx pin 1.

That should provide you with a transverter that works with the K3. If
it does not work properly, plese let me know.

Ian,

Based on information I received from Wayne, I do believe that K3 ACC pin
7 is now dedicated to TX INH. There were complication in sharing it.
If the change is not in the firmware version you are using, it will be
with a forthcoming update. In other words, it cannot be used for XVTR
ON. The +12 volt output from the back of the K3 should do nicely even
though it means "Y"ing out one of the cable wires.

Hi Don,
Thanks for the update. I am running 2.02 and the rest of the latest
firmware. I have been merrily using my transverter but not for a few
weeks as I moved the shack around and need to make up another power
cable. If this is the case, can we have a heads up from Elecraft please?

It appears that one can use pin 7 for "XVTR ON" if it is not being
used for INH (at least that's the case with FW 2.02).

If CONFIG:TX INH is OFF, pin 7 will be 5.0 V when the K3 is on and
will work for XVTR power control. If CONFIG:TX INH is set to either
LO = INH or HI = INH, pin 7 can not be used (reliably) for XVTR
power control.

Re: K3 Transverter Control Cable

In reply to this post by Don Wilhelm-4

I've just installed the KXV3, which seems to be workingas I can receive
signals through the alternate rx antenna socket.

On Config I get NOR and Test. I don't get 'ON' as the manual indicates.

I have the XV144 with a lead to run from the basic K2 without the
transverter interface. It works perfectly well on the K3.

Am I incorrect in thinking that this cable will run from the K3 when put
into the RS232 connector on the K3?

It would appear, on re-reading the manual this morning, and what has
been said below, that I need a seperate lead from the K3 ACC connector
as the RS232 lead did not work. If that is the case, what do I need to
do with the XV144 settings? Should the jumper settings till be set to
the K2 settings?

I can't find anything on the Elecraft website about this.

Any assistance much appreciated.

Yes, John, you do need a separate ACC lead wired as quoted by Gary as
follows....
--- --- --- --- --- --- --- --- --- --- 8< --- --- --- --- --- ---
You need to use the DE-15 AUX I/O connector to interface with the XV144.
The auxbus line is needed for addressing and control of the transverter
(using its ADR setting and the XV's DIP switches). And the KEYOUT-LP
line is needed to place the XV into transmit mode, in the same way as
the 8R line does for the K2. So you'll need to make a cable like this:

XV DB9 K3 DB15

Pin Pin

1 ground 5
6 auxbus 2
8 XVTR ON 7
9 PTT 10
--- --- --- --- --- --- --- --- --- --- 8< --- --- --- --- --- ---

My K3 settings for the XV144 are as follows...

KXV3 nor
XV1 ON yES
XV1 RF 144
XV1 IF 28
XV1 PWR L1.50
XV1 OFS -0.89 (Yours may need to differ)
XV1 ADR trn1

I hope that helps.

Thanks David & Roger for the advice. I should be able to sort it out now.
