“Copy All” - A single click copy of the entire contents of the Incoming Message Window to the

Windows Clipboard for pasting its contents into another application. This saves the right click

menu selections or manual high lighting steps to copy from the message window.

“Grab Last” - Grabs the last message received and clears and replaces the outgoing message

window contents. The grabbed message can then be edited for relay or highlighted for sending

fills using "Send HL" as needed as rapidly as possible over other copying and pasting methods.

Should there be no message to grab a message box is displayed to the user. The last received

message is always available until another message is received no matter how many times "Grab

Last" is used.

Status

“MODE” - Displays the Data Rate and Interleaver settings of the incoming data while data is

being received and NO DCD when incoming data stops.

“STATE” - This is a work in progress, it displays the various states while awaiting detection of

preamble sync, decoding data probes and payload data and completely decoding the payload

through to the completion of the End Of Message (EOM) indicator. The current STATES that are

displayed and there meaning are:

 IDLE: The modem receiver is hunting for a legitimate signal and PREAMBLE data to

decode.

 DATA: The PREAMBLE has been found and is decoding as seen by the ERROR window

values still changing, when frequency error values lock, the KNOWN/PROBE data and

PAYLOAD data (consisting of the message) decoding starts taking place and the message

(payload data if any) is then available.

 NO EOM: The message has been decoded through the EOM. This is displayed so fast and

immediately switches back to IDLE that it will often not be caught by the naked eye.

However, if it remains displayed then DCD has likely been lost and gibberish displayed to

the Incoming Message Window if Display on EOM is not checked and the RESET button

should be pressed for a hard reset to place the modem back into a known IDLE state.
