- METERING A modulation
scale (for use on AM only) has been added to the
signal meter. Markings have been added to the
signal, power output and SWR scales to make them
easier to use. Also, positioning of the two
meters has been reversed for ease of use -- the
SWR/POWER meter is now on the left, and the
SIGNAL/MODULATION meter is on the right, closer
to the frequency display.
- RX/TX INDICATOR
The LED above the power switch
is green during receive and red during
transmit.
- TALK BACK CIRCUIT
The new Talk Back circuit has a
volume control with an "on/off" switch so that
it can be used at any time. This is convenient
when testing new microphones. The audio signal
available on the main PC board is not very
strong, so the Talk Back is not very loud even
at maximum. However, it is sufficient for most
applications.
