[Elecraft] KPA500 Questions

[r miles]

Is the inter connect cable between the K3 & KPA500 not available yet? I 
read the online manual but not clear on SWR. If say the SWR is 1.5 to 1 
does the display show forward power in watts or a combination of forward 
& reflected? If the SWR is less than ideal will the 500 back the power 
down to ease the heat build up? Maybe I'm just missing it. I'll re-read 
the manual again
