Re: Receiver sensitivity parameter

Confusion may also arise from the use of u for µ
when the latter is not readily available on the keyboard.

Hi Bruce,
Sorry to confuse.

I used dBu-dBµV/m to try to show that they are the same thing.
Should have stated dBu (equivalent to dBµV/m).
Corrected paragraph:

The modern DSP receivers like the Tecsun PL-380, 310, etc. which employ the Silicon Labs chips,
measure and display dBµV as received at the tuned front end across a load, not dBu (equivalent to
dBµV/m). They call it the RSSI indicator, and erroneously mark it as dBµ on the display [Greek 'mu'
again]). It is not the same measurement as dBu, which is derived from volts or millivolts/meter.
73s,
Bill
