Richard,
The components that could be damaged with J7 in place are a few in the
automatic power on circuits. Move the jumper to J8 and with the power
switch in the non-activated position and the K2 to XV control cable in
place, see if it turns on when you select the 144 MHz band. If so, no
harm done.
The failure to transmit is an entirely different problem. Check all the
jumpers that relate to your IF interface (single cable or split RX/TX)
and the jumpers for you chosen power level - then try it.
If you still do not get any power output, tell us how you have the TX/RX
cables configured, you drive power level, and what you are using to
determine power output level (into a good VHF dummy load).
Do you have an oscilloscope with a 10X probe that can work well at 28
MHz or an RF Probe? You will need one or the other to do much
troubleshooting.

Hello,
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.
