Ron, You are doing it right - even if the BFOs for LSB and USB are severly misaligned, the voice should still be 'similar' in that the pitch should not change, although it may sound a bit muffled on one or both sidebands because the lows (or highs) may not be at the proper amplitude for a good voice response because they are not inside the passband.
The only caution that I can offer on your CW method is that some folks have trouble matching the pitch, and also during the times WWV is transmitting a tone (either 500 or 600 Hz), it is easy to zero on the tone instead of the carrier - if you find yourself off by 500 or 600 Hz, that may be the explaination - double check during the minutes when no tone is transmitted. Since my hearing is shot too, and I don't possess the gift of perfect pitch, I prefer to use LSB only and look for the tones at the proper pitch with Spectrogram - you can get within 10 Hz (limit of the K2 dial steps) or closer with ease - to me that is the easiest and the most accurate, and you don't have to monkey with calculating the CW offset stuff. 73, Don W3FPR > -----Original Message----- > Greetings. > Several times on this Reflector we see posts telling people > to "tune into WWV exactly".
