     The reviews are interesting. Some say its the best and 
they use it all the time, some have the typical reaction to 
anything old, "This used to be good but isn't any more. It 
won't do...etc, etc."  Well, the laws of physics have not 
changed and if it was good in the past its still good. You 
just have to learn to use it correctly. We live in a world 
of equipment that does not require any technical skill to 
use; it does everything automatically (maybe). Of course, 
hams are supposed to be able to set up and maintain 
communications with very simple equipment in emergencies. 
Having a corps of those with technical knowledge and skill 
to establish communication in an emergency is the whole 
justification for amateur radio to exist and be allocated 
band space. I think some of the rice-box radios are very 
good but they don't teach the owners much other than that 
one can have too many settings in a computer menu.
    I also think the above is a good justification to know 
Morse. Even if you are slow it provides a method of 
communication that works with the simplest possible 
equipment.
    Pardon my soap box, sometimes I just can't help it.
