My K3, on receive, with the KAT500 in-line, the P3, and my massive 70A Astron
p.s. powering the K3, drew about 20A DC. Putting the K3 in transmit mode,
with just under 12W drive (so as not to kick in the 100w amp) required about
30A DC. Boosting the output to 50W drew about 70A DC.

The complexity may involve sorting out the headphone connection from the

I believe I need to order the y cable as well but I'm not sure.
I've down loaded the manual and I can't find the wiring diagram between
the P3 and K3, specifically the nice picture of the back of the units

Hi
No you do not need a Y cable to connect the P3. You connect to a serial cable
between them and the p3 then connects to the MicroHam.

The answer is NO.
Even with speakers set to 1, one channel of the speaker jack is still
connected to the output of the audio amplifier. The menu only activates
one channel, it does not change the physical connection.
Replace the plug with a stereo plug wired only to the tip and
An RS-232 Y cable is needed for a device like a SteppIR antenna, which
receives but does not transmit data on the RS-232. The Y goes in the
connection between the P3 and the computer.

There is no advantage to grounding the negative power lead,

It looks like you are ignoring the fact that your power supply is less
than 100% efficient.
Power into the supply does not equal power out of it.
The readings from your Astron current meter are more realistic for the
DC Current requirement.

NaP3 has a mirror image rejection algorithm. Tune to an S-9 or greater
signal and wait a bit to allow it to work The stronger the signal, the
faster it will be corrected. An XG3 set to -33 dBm will work quite nicely.

Here is how I'd do it, your mileage may vary.
I'd measure the power draw at 100 watts key-down, and the power draw for
receive.
I'd assume 50% duty cycle. You can skip a lot of math by either
ignoring the receive power draw (if it's low enough) and dividing by
two, or adding them together

Jed,
If shorting the RCA plug that goes into the WinKeyer 'fixes' the
problem, I would suggest that the problem is in the WinKeyer. The
optoisolator (U1 or U3) that 'closes' the key contact may have enough
resistance to keep the K3 from keying reliably. It would be informative
to hang a DC
