[Elecraft] K3S SSB TX monitor - feature request

[Edward R Cole]

Mel,

Guess you are unaware, but I am on 6m-eme, 2m-eme, and 23cm-eme.  The 
RTLT is approx 2.5 seconds.  But voice is rarely used and eme 
stations rarely operate in Duplex.  Of course one can receive your 
own reflected signal for a short duration; that is called receiving your echo.
