[AMPS] SB-220: Operate/Standby Switch

[i4jmy@iol.it]

If you can adjust driving power to obtain the desired out, the CW 
position becomes basically meaningless, expecially if considering that 
tubes work better at 3Kv plate voltage.
Anyway, to realize a ST-by position without drilling anything and 
leaving unmodified the SSB/CW switch, or you place an external switch 
along the PTT line, or you replace the meter switch with one having 4 
positions and two sections, using the second section to switch on and 
off the PTT line.
