When building the K2, one installs a couple of back-to-back diodes across the input of the IF amplifier to clamp the input voltage. However, if there is a large signal on the antenna during receive, what protection is there for the RF preamp transistor and the first mixer? Does the micro controller monitor the V_RFDET line on the antenna during receive, and switch out the preamp/switch in the attenuator when a large signal is detected?
