[Elecraft] KAT500

[Dick Dievendorff]

For a K-line, you'll want a 15-pin cable from K3 (after the Y) to the KAT500
and another from the KAT500 to the KPA500.  The KAT500 interrupts the KPA500
key line in that cable during tune, and both the KAT500 and KPA500 observe
the K3's BAND0 thru BAND3 lines. 

If you aren't using a K3, then the KAT500, like the KPA500, can sense band
changes by counting the Tx frequency.  

But it's very convenient to band switch the K3 and have the ATU and amp
follow without requiring a transmission. The ATU switches to the last-used
antenna on band switch (or to a fixed antenna you configure).  It's nice not
to have to send a "dit" to make that antenna switch happen.

The manual is in progress.

I have currently have a y-cable at the rig for the MH MKII and the KPA-500.
How will the KAT-500 play into that? A Y-Cable on the KPA-500? 
I see no manual for the KAT-500 yet!
