[ICOM] 756 PRO + AH-4??

[Ynkedragon at aol.com]

Question to anyone using the 756 PRO with the AH-4 external tuner:

When you change bands does the transceiver automatically switch briefly to 
XMIT to provide RF for Tuner adjustment?  Or, do you have to take a specific 
action, such as depressing the "Transmit" button on the front of the rig?

WHY I ASK.  A company called Quicksilver Radio offers a gizmo (see April 2005 
QST, p.146) called a TuneRite™ designed to make the "PRO believe that it is 
connected to an AH-4."  The transceiver will provide about 8 watts RF for about 
10 seconds for antenna tuner adjustment.    This interests me cause I use a 
Johnson Matchbox tuner on several bands.  The device would allow me to make 
more rapid band change tune-ups.  

I'm trying to determine if the activation of the transmitter [for tuning] 
would require my action (preferred) or if it would be automatic with each band 
change?
