[Elecraft] Another KPA500 question

[bob finger]

I too am considering purchase, but before I do an interface question or two.

I will NOT be giving up the big amp...assuming I hook it up to Antenna 2 
on the K3 and use the PTT line can I
1. put the kpa500 on ant 1 and use the accy interface, and keep the big 
amp on ant 2 with the ptt line?  I assume yes....
2. If the kpa500 is in standby mode will the accy connection to the k3 
be transparant ie  can I set power out on ant 2 independently and key 
the big amp via the ptt line as usual?

The point being I don't want to have to physically reconfigure the 
cabling etc. when I want to use the big amp.....and no way  will I daisy 
chain the amps.   Thanks in advance.  73 bob de w9ge
