Re: Receiver sensitivity parameter


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.
