RX attenuated...  

Q3 and Q5 are RX switching, they only have DC and during RX.

The drain of Q3 should have near 0 volts (less than 1) during RX.
gate of Q3 should have More than 6V.

IF gate of Q6 is not at least 6V during RX check Q5 gate of
Q5 should be 0 Volts or very close to that.
If that is not true check what is wired to jack X2 (Keying) or
possible Q6 in wrong or has a shorted solder connection.
