On the other hand, G3YYD has previously suggested that software using
2Tone use the RXM_Switch command to turn off Net when calling CQ (F1/F11 
in Writelog).  That could easily be complemented by turning Net
ON if the transmit frequency changes by more than 500 Hz or 1KHz.  That
would result in Net OFF when running (call CQ, Net goes off) and Net ON
when in S&P or jumping frequency to grab a multiplier.

In any case, Net ON/OFF is not a significant issue since 2Tone limits
the AFC range to not more than about 50 or 60 Hz (depending on version)
from the preset Mark (or Space).

Net is automatically OFF at all times when using FSK - the FSK tones are
fixed in Rttyrite (Hardware or Software Generated FSK).
