Hello André, I believe S/N reports are realistic in any BW if you are telling the BW at which the SNR has been measured. Unfortunately in many S/N reports the associated BW is missing. and therefore
Hello Clemens, E.g., if your FFT is set to a bin width of say 5Hz and a carrier lies 20dB over the DANL (displayed average noise level) it will have a SNR of zero dB in a 500Hz "IF"-bandwidth and the
Hi Roeloff, while 0dB SNR referenced to the RX BW is commonly defined as the "minimum discernible signal" I agree with you that with the listening skills of an experienced operator and low cw speed 1
