 |
|
The wood/fiberglass aircraft I bought has a single NAV-COM (KX-155A) and a single embedded comm antenna. It also has an 2002-vintage PS Engineering PMA-7000B audio panel. I would like to add another comm radio to the aircraft and was considering something like the Yaesu FTA-550. This radio has provision for a headset connector and for 10±0.5V power input.
I was wondering if it is possible to splice the headset connections from the portable into the audio panel as COM2, and get “normal” comm radio functionality, specifically
<![if !supportLists]>1. <![endif]>Can the mike output from the audio panel drive the portable?
<![if !supportLists]>2. <![endif]>Can the stick mounted PTT, through the audio panel, key the portable?
<![if !supportLists]>3. <![endif]>Can the portable headset output be used as input to the audio panel?
<![if !supportLists]>4. <![endif]>What might be a recommended way to get the 10V feed for the portable?
And if it is possible, what kind of special connections/modifications might need to be made?
Thanks,
Andy
