I would guess I am running maybe 5mW into a modified CB ground plane
antenna.
Serious mismatch, but my "beacon" was only intended to reach about 1
mile.
For an S2 reading I had to back the power down ~50% from max legal. So
assume I am running 2.5mW with no attenuation, so for extra credit,
what is my
power level at -63dB?

Your question makes no sense. What is the reference level? 1 watt, 1 mW, 5
mW, 2.5 mW?

..5 microwatts is 63 dB below a Watt.
..5 nanowatts is 63 dB below a milliwatt.
2.5 nanowatts is 63 dB below 5 milliwatts.
1.25 nanowatts is 63 dB below 2.5 milliwatts. (Is this the one you want?)

2.5 milliwatts is 3 dB below 5 milliwatts.

See a pattern in any of this?
