... The manual says pin 6
has 8v. This post says "5v when BIAS is on".
You may have misread my post, or I may not have been sufficiently clear.
Front panel Mic Jack Pin 1 (Mic Audio) has 5V if and only if BIAS is set on,
such as you might need for electret microphones. Otherwise it has none, as
required for dynamic microphones.
Front Panel Mic. Jack:
Pin 2 (PTT) has 5V no matter if BIAS is on or off.
Yes, PTT has nothing to do with MIC BIAS. This voltage is present so the
radio can tell when you ground the pin to signal that you wish to transmit.
Pin 6 has 8 V always on.
Rear Panel: 8V when BIAS is on.
Front Panel: 5V when BIAS is on.
Front Panel Mic Jack pin 6: 8V always on.
We are in complete agreement.
