[Elecraft] XV144 Transverter and K2

[richard hubbard]

Hello Don,

Sorry for the late reply. Thanks for the guidance I found that I had one of the jumpers in the wrong position, my eye sight is not what it used to be. 

I have now run int an info 80 error which only occurs when the transverter control cable is connected. When I disconnect the transverter the error clears after I cycle the power, however the K2 does not see the KPA100 which is in a separate EC2 enclosure with the ATU.  Within the K2 menu whilst I can select PORT ON;  PA and ATU are blank (three dashes). When I power up the K2 the relays can be herd to click in, as per appendix E in the K2 manual.  Do you think that this points to an issue with the Aux bus, I have tried a had reset however the PA and ATU are still not seen?

Thank you.

Best regards,

Richard Hubbard.

>> I have recently bought a XV144 transverter, which was used on another non Elecraft Rig. I followed the setup for use wit a KS however did not notice that thee was a soldered jumper on J7. Looking further into the manual I see that using the K2 wit the Transverter J7 shorted can cause damage. I currently have no output from the transverter. Does anyon know what to look for.
