There's an awful lot of gain between Q90 and the IRF510's.
If that trace between the relays for rx is not grounded during transmit, it will carry enough RF energy
to create a really impressive oscillator.
Unfortunately, it won't necessarily be at the operating frequency.

In transmit, the trace between K3 pin 14 and K1 pin 12 is disconnected from the antenna at K3 and connected to ground at K1.? What is the designer's intention for doing that?? Wouldn't disconnecting the trace from the antenna be enough?
