Europa-List: Navaid Autopilot.

[Michael Parkin <Mikenjulie.Parkin@btopenworld.com>]

To prevent interference with the Navaid system during radio transmission, the 
installation
diagram calls for an earth on pin 7 ( through the PTT button) for
the duration of the radio call.  The circuit also calls for a diode in the 
radio/intercom
line.  This diode prevents correct operation of the PWR/XMT led on
my PS intercom system.
Does anyone know the purpose of the diode, and is it OK to leave it out???
