  Jim - The HT-40 came out before zeners and leds unless I'm really out 
in left field.

Bill Breshears', WC3K, modification used those components to give an 
over modulation "indicator" to adjust the mic gain with, and allow the 
operator to run with a clean signal.  Circa 1999 - 2002.

Bob - N0DGN
