I estimate that my receiving loops are 20 or 30 dB down from a full
sized antenna such as a 1/2 wave dipole at 50 or 60 feet, an antenna
that a lot of casual operators use (often to their detriment) on 160
m. Sometimes I'll just add 30 dB to the S meter reading.
Alternatively, I'll tell the guy I'm working that I am either using a
speaker or headphones to hear him and with the latter, what % of his
transmission I copied.
