Put a t/r relay in the antenna, and switch the speaker.  Remember to switch
in a resistor load in place of the speaker.   I think the SX-99 has 500 ohm
and 8 ohm outputs, you might bridge a 680 ohm resistor across the receiver's
high impedance terminals.

You should be feeding the receiver's 300 ohm balanced antenna input with a
balun.  You will enjoy a noticeable reduction in noise and increase in
spurious signal rejection.
