Www modes sxicom
Looks like you have to drop below 0.4V for the relay to turn off.
Any chance your circuit is holding the coil voltage above that? What I was trying to ask (before I ran into technical difficulties) was if the load on the relay switch is inductive (not the relay coil), and if so, does that have a flyback diode?
I am in agreement with @Bruce Abbott's comment, above.
RF VOX functions correctly in CW, SSB modes, off delay is nearly 300 ms though it is not desirable to use RF VOX with SSB and CW.
Relay will switch over under HF power in the time of every pause in transmission (TX).
LNA protection from random transmitter power feed to their output based on RF VOX functioning.
LNA without energizing is every time in bypass mode.
