Auto-Sequencing algorithm for DXpedition station:

Start:
    CQMsg = "CQ KH1DX"   (or "CQ UP KH1DX", "CQ 116 KH1DX", etc.)
    TxMsg = CQMsg
    Ntry = 0

Receive:

Auto-Sequencing algorithm for those calling the DXpedition:

Start:
    TxMsg = "KH1DX MyCall"
    InQSO = false

Transmit:
    TX                                                # (... takes 13.6 s)
    go to Receive

Receive:
    RX                                                # (... takes ~14 s)
    if(RxMsg[i] contains "MyCall <rpt>")
        InQSO = true
        TxMsg = "KH1DX MyCall R<rpt>"
	go to Transmit

    if(RxMsg[i] contains "<rpt>")
        TxEnable = false
	go to Receive

    if(RxMsg[i] contains "CQ KH1DX")
        TxEnable = true
