[TenTec] Orion 2 Firmware 2.044A Released

[Dr. Gerald N. Johnson]

The best monitor for output and modulation is an oscilloscope. With it, 
you can see carrier level changes and overmodulation, both upward and 
downward. The 100 watt linear will start to clip upward modulation peaks 
a bit above 100 watts (possibly set by ALC driven by output power peaks. 
If downgoing modulation cuts off the carrier, that also makes splatter 
and when detected in the AM receiver sounds just like clipping because 
the audio envelope IS clipped.
