Okay...so I am dbm challenged.
Please translate these into uv or S units (9 = 50uv).
Thanks,

Doug: at 50 ohms,
-28 dBm = 8900 uV (8.9 mV)
-15 dBm = 39,800 uV (39.8 mV)
0 dBm = 223,600 uV (223.6 mV)
Your reference, s9 = 50 uV = -73 dBm

Should have added the appropriate S-unit readings as well, I guess.
Assuming S9 = 50 uv @ 50 ohms, -73 dBm:
-28 dBm = 8900 uV (8.9 mV) = S9+45dB
-15 dBm = 39,800 uV (39.8 mV) = S9+65dB
0 dBm = 223,600 uV (223.6 mV) = S9+73dB

Correction to -15dBm signal to S9+58dB sri, too tired for math
