They are actually forward biased, so that path is "on". By activating PA
disable on the accessory jack you also disables the T/R relay, thereby
setting +13.6R on all the time, (and also the mute signal on the
accessory jack is unmuted.)  An interesting setup indeed :-)

Thanks for adding the note about the wire inside the cabinet connecting
EXT ANT and EXT RX. Forgot to mention that...
