[ICOM] Computer Control Interface

Have used virtually every Rig interface on the market when I was testing
digital interfaces for EMCOMM use.

I did not test CW only "digital modes"

Homebrew, Rascal, Buxcomm, MFJ  & RigBlaster... Serial COMM Port.. Internal
Computer Sound Card

MicroHam Keyer... USB Port ... Internal Computer Sound Card

RigExpert... USB Port.. External Sound Card in RigExpert

For Modern Computers... buy a USB device.. MicroHam or RigExpert...

For DX ... buy an External Sound Card Device... RigExpert..

In parallel testing RigExpert always was able to decode digital signals
about 6  - 10db better than the devices that used the internal computer
sound card.. as it did not live in the high noise environment inside the
computer..

Most times I would still get 100% copy on the RigExpert when the other
devices on a parallel computer attached to the same radio failed to copy at
all...

I do not have any financial other other interests in any ham product
company...

Ok I give up on this little project, it is quickly
becoming not worth my time.

Is someone using an interface with an Icom PRO or II or
III that does all the soundcard modes and FSK modes along
with keying CW from A SINGLE COMM PORT that actually
works?

I would like to know what your using so I can look into
getting one.

What is recommended by you guys with the experience?

Code may be taking a back seat for now,
but the pioneering spirit that put the code
there in the first place is out front of it all.
