[Elecraft] K3 Amtor receiver recovery times

[Dave G4AON]

I've been trying my K3 on Amtor with mixed results, the TX delay time is 
not an issue (around 12 mS from earlier measurements), however the 
receiver recovery time is appalling. Has anyone else checked their K3? 
Mine appears to need 200mS to fully recover receive audio... It can't be 
this bad surely as it's supposed to receive on CW QSK at 50 wpm.

Any thoughts?
