HF preamplifier RX/TX block diagram, UPDATE

I decided to update the previous block diagram adding:

- More "simple" description of the TX/RX relay from Ramsey.
- A few LED's that will be helpful when switching ON/OFF such or such block.
- updated DPDT block diagram...

Blue color wires are HF signals.
Red color wires are for power supply signals.

Have fun !
