well to start with the outside signal is garbled up until i switch to low then the user clears up, when switching back to hi he gets garbled up again and when the user unkeys i here 2 seconds of robotic noise, and the robotic noise does not happen on low.
i think that clear enough desense, with the tracking gen i have 86db of isolation in the 4 pack cans not perfect, but really not bad i also use a 10'' 3foot high band pass cavity set to 1 db of loss and it gives me aprox 20db at 500khz window on my rx freqency honestly i don't think you could ask for any better then that, but the desense sounds like i have no duplexer's and I'm starting to point at the poor construction of this over sized empty box and shielding mobile radios give you Tony NN1D
