Baby steps here, coping with my first-ever amplifier... First question:
A phono cable must run from the amplifier's "Relay 1" jack to ...
something on the O2. Is it TX OUT 1, TX EN 1, or AMP KEY 1?
The SPE Expert 2K-FL manual states: "RELAY This essential link allows
the amplifier to be put in the transmit state. To do that it is
necessary that the inner pin of the phono connector is connected to
signal ground. This is normally done at the transceiver with either a
'close-on-ground' relay, or with a switching transistor. It is important
that the voltages at that terminal do not exceed 12 Vdc. On the
transceiver this link is often called SEND or TX GND. Refer to your
transceiver manual for more details."
This seems to come first, before dealing with ALC and CAT.
