I support the request for a fixed level line out for the TX audio very much.

Does anyone have a design for a FET preamplifier for a
D-104 that will work off the K3 mic bias (rather than the
separate +8V line) and the typical 3.3V mic bias in the
current crop of laptops?
Joe,
I would try the circuit shown in the link below.

I'm using a TGE (N8XJK designed) boost regulator on my battery-powered setup.
By the K3 meter (when I get time I'll verify this) the supply voltage on

If you aren't married to the original element you could change it out to an
electret element wired directly to the K3 input with the bias turned on. I

Unless I'm mistaken, always a possibility, the Line Out doesn't have the

Anyone know of a serial port sharing software similar to LP-Bridge,

If one is going to float this across a battery, need to take notice of
the normal float voltage for the cell. This is a nominal 13.8 which
is just a characteristic of an automotive six cell lead acid battery.
There are other kinds, and this 13.8 may change to something else.
If you can actually
It sure would be nice if somebody came out with a hardware dongle that
did this splitting into 3 or 4 ports.
While I use LP-Bridge here, I'd rather do with a hardware solution.
Of course the P3 already shares and passes through one port.
