Richard -
Depending upon your mic and voice characteristics, '8 - 8:30' is VERY
low. Most mics need more like 10 - 10:30 GAIN settings. IF your mic
has in internal preamp, such as the D-104 with preamp in the base, set
the XMTR GAIN to about 10:00 and then increase the mic's gain control
until the meter kicks up to 100 - 150 mA _on voice peaks_. You will
only see the 'loaded' current if you whistle steadily into the mic.
A scope is the BEST way to monitor modulation, since it has an
instantaneous response, while the meter is too slow and reads more like
the average response.
The ALC is good enough in the Drakes that it's just about impossible to
drive them into distortion, BUT if you are using an external amp you can
easily overdrive it.

Per the manual my Xmtr gain setting is at about 8-8:30. But I have no
meter movement when I transmit SSB. If I increase the setting to 12:00
I get deflection while transmitting.
So How should I set my Xmtr gain control?
