Hi Ed, Each of the K4's receivers has a fast-acting Carrier Operated Relay (COR) that activates between +20 and +25 dBm. When the COR triggers, it disconnects all active circuitry of the associated receiver from the antenna. COR hold time is programmable.
For signals that are below COR level but still extremely strong, the K4 can automatically (at the user's option) adjust receiver front-end gain to optimize dynamic range. 73, Wayne N6KR > On Oct 22, 2020, at 4:51 AM, E.H.
