[ICOM] ICOM marine/ham radios

Hi Dave,

Guess I should have expressed more explicitly why I "tossed my penny into
the ring."
I am tired of discussions centered on how to calculate the proper R-value
or relay
necessary to key some boat anchor KW Amplifier; let alone the chorus of
amens to
Icoms latest product rumors.

The FCC Rules & Regulations for all services are still based on the state
of radio art 
which existed from mid- to late- 20th. century standards of construction
and signalling
methods.  From primitive spark generators, through vacuum tube circuits,
solid state, 
from land, sea, air and aerospace  Radio Amateurs have pioneered and
matured the art.

Few hams today actually build their equipment.  Face it: The modern HT
for example
is made of the same stuff the professional services use. The modern need
is for police, fire,
gov'mt, military, and yes hams (FEMA) to intercommunicate.  And don't
forget the
merchant ships, aircraft, satellites, etc.  What will make all this
possible? Digital radios!
My New Icom IC-V82 was purchased last January.  Add some $$ and a drop-in
module
converts it to a digital voice/data communicator. Its not yet ready for
prime time but is
an example of what is to come.

The FCC came into being in 1937,  It has three principal purposes:
1) Allocate the radio spectrum. Shared between all license classes and
services.
2) Set standards for equipment, construction, operation, and maintenance.
3) Define, test, and certify the Operator needed to control and station
equipment. 

My premise is that the very nature if digital equipment and methods (i.e.
determinism,
stability, operational performance, self test, closed-loop operational
limits) will negate the
future need for Operator skills.

Commercial Amateur Radio are being built to the same standards as Public
Safety radios,
and as are most military radios.  They come off the same production
lines. Cheaper too!

I have owned two Kachina KC505's and now have a TenTec Orion. I've sold
all my
long loved Collins's in favor of the new DSP rigs.  I have a DSP-10 also.

Have some fun.  Google DSP-10.  Google HP-3801A.  Try something new.
Even the FCC has approved the use of Software Defined Radios.

Thats enough,                              Think 21St Century Radio
