Confusion still reins about the front panel mic. jack. The manual says pin 6
has 8v. This post says "5v when BIAS is on". So I measured it.
Front Panel Mic. Jack:
Pin 2 (PTT) has 5V no matter if BIAS is on or off.
Pin 6 has 8 V always on.

1. How many volts is the mic bias?
Rear Panel: 8V when BIAS is on.
Front Panel: 5V when BIAS is on.
Front Panel Mic Jack pin 6: 8V always on.
2. Why does the filter selection always end in 5 (2.65, 2.75, 2.85 &
etc)?
The filter system is currently handled in 50 Hz steps. Might change in a
future firmware rev.
3. Can the Absolute S Meter function be set to ignore the RF Gain
setting?
It always takes the IF AGC control voltage into account. Since that
voltage
could be generated by a signal or the RF Gain control, the S Meter assumes
it
is a signal and applies it to the calculation.
