Proposed new message types have 77-bit payload: 74 information bits
|
||||
and 3 bits for "message type". Note that Type 0 (as defined by i3)
|
||||
uses only 71 information bits, so it allows another 3 bits (here
|
||||
called n3) to be used for 8 sub-types.

Notes:
|
||||
NB: three 74-bit message types and two 71-bit message subtypes are still TBD.
|
||||
----------------------------------------------------------------------------------
|
||||
|
||||
0. Free text message.
|
||||
Further details:
|
||||
|
||||
1. 74-bit standard message: two 28-bit callsigns, each with an extra
|
||||
bit to indicate "/R" Rover status; one bit for "R" preceding the grid
|
||||
or report; 15 bits for grid or report.
|
||||
0.0 Free text, up to 13 characters.
|
||||
|
||||
2. Type 2 is for the annual ARRL RTTY Roundup. Optional "TU;" uses
|
||||
1 bit; then two 28-bit callsigns, optional "R" (1 bit), a 3-bit
|
||||
report, and finally 13 bits for US state, Canadian province, or DX
|
||||
serial number.
|
||||
0.1 DXpedition mode as developed for KH1/KH7Z.
|
||||
|
||||
3. For European VHF+ contests. Like Type 1, but /P instead of /R.
|
||||
0.2 Report, QSO serial number, 6-digit grid, and Roger for EU VHF contests.
|
||||
|
||||
0.3 ARRL Field Day exchange for up to 16 transmitters.
|
||||
|
||||
0.4 ARRL Field Day exchange for up to 17-32 transmitters.
|
||||
|
||||
1. Two standard callsigns, Roger, and grid or report. Each callsign
|
||||
may have an appended "/R" to indicate Rover status for NA VHF
|
||||
contests.
|
||||
|
||||
2. Standard message for ARRL RTTY Roundup. Optional "TU;" at
|
||||
beginning to finish a previous QSO; then two standard callsigns,
|
||||
optional "R", a 3-bit report (529 to 599), and 13 bits to indicate
|
||||
US state, Canadian province/territory, or DX serial number.
|
||||
|
||||
3. Same as Type 1, but uses /P instead of /R. For European VHF contests.
|
||||
|
||||
4. One nonstandard call with up to 10 characters, one hashed call, Roger,
|
||||
and signal report.
|
||||
|
||||
4. For European VHF+ contests. Transfers serial QSO number (12 bits)
|
||||
and 6-digit grid locator (25 bits).
