To All from PA0SE Dave, G3YMC wrote 3. On the subject of receive notes. I also noted that Harry optimises his filter for 1kHz. Many operators including myself prefer a lower note, 600-800Hz or even lower. I suspect it is the optimisation of the frequency relative to background noise, and with a narrow audio filter may be less noticeable> The Swedish thesis shows that around 500Hz the ear/brain is at its best in copying wek signals in noise. 73, Dick, PA0SE |
