[VHFcontesting] Any one use an FT-991A with a mast mounted pre amp?

[John Young via VHFcontesting <vhfcontesting@contesting.com>]

I would like to add a 2M mast mounted pre amp to my station.  The FT-991A has a 
rear jack for tuner and RF power amplifier control.  The manual describes each 
pins purpose (ex: TX INH, TX GND, GND) but it gives no information on the 
function of each pin or more importantly timing information.  I would like to 
think that I can use these pins with a set of relays to prevent transmission 
until the pre amp is taken out of the RF transmit line.


I can not find anything on line after several google search sessions describing 
these pins, their affect on the transmitter  or showing how anyone else has 
used a mast mounted pre amp with the FT-991A (or the FT-991 for that matter).


Any advice on how to proceed would be appreciated.
