Re: Analog Vs Digital Radio



I'm not using a DSP-10, but I have the same problem with front panels. I've
been using computer-controlled transceivers since 1994 and the panel full of
buttons and knobs on the IC-821 now seems much harder to use. The
orientation and size of the keys on the computer keyboard and the
orientation of the knob on the tuning knob accessory make the
computer-controlled radio much easier to use. The computer display is also
much easier to read.

However, the IC-706 is probably not a fair comparison of digital and analog
radios. It is the worst radio that I've ever used in its ability to detect
weak signals. I could hear better with a Hallicrafters S-38C.
