Running it all together

• Now that we have the radio hooked up to the
  computer, lets get it working with the software
• Install MixW on your computer and make sure it
  all works like advertised.
• Next well show how you set it up for remote
  control.

The Eye Of A Needle

  called The Eye Of A Needle or TEOAN
• This allows the USB connection between the
  computer and the RigExpert to be extended by a
  computer network (locally) or through the Internet

Then Run MixW on Your Laptop

• To date, I check into the India net weekly from
  my hotel room in Fairfax County, VA
• Olivia and MT63 modes
• I have checked into the India net from the
  Atlanta Airport between flights
• Using the airport 802.11 wireless internet access
• I am able to change frequency and modes (USB/LSB)
  on the radio, tune, etc.

15
What is Possible?

• Anything.
• MARS deployed to remote sites accessing the
  internet via cell phones connecting to the HF
  station in Ocala
• MARS deployed to local EOCs with no HF but with
  Internet (typical hurricane scenario) using an HF
  station outside the emergency area (Ft. Huachuca,
  etc)
• MARS members without HF equipment checking in to
  nets using MARS club equipment

16
Two Limitations

• Two Major (??) limitations to this
• You cant hear the signals you can only see
  them on the falling raster display (or spectrum
  analyzer mode)
• But that doesnt seem to affect operations
• You have to use the RigExpert Interface
• I dont KNOW IF THIS TRUE OR NOT,It is just what
  we have experimented with so far and determined
• It IS expensive but, it is NICE!!

17
DEMONSTRATION

• We will check in with the Charlie net using
  MT63
