    pqsoOrig->pcallTx		originator's call	**ORIGCALL**
    pqsoOrig->pstrTxName	name orig sent		**ORIGNAME**

    if qsoOrig and qsoPrev are paired/matched, then orig wkd me ...

	pqsoOrig->pqsoTrPair	points to my qsoPrev
	pqsoOrig->pcallRx	my call			**NEXTCALL**
	pqsoPrev->pcallRx	orig's call		**PREVCALL**
	pqsoPrev->pqsoTrPair	points to his qsoOrig

    ... else qsoOrig was with a non-log-submitting intermediary, and
    qsoPrev was also with an inter.  likely that both inters are the same,
    and if qsoOrig was inter's #N, then qsoPrev was inter's #N+1.

	pqsoOrig->pqsoTxSkip	points to my qsoPrev
	pqsoOrig->pcallRx	inter's call		**NEXTCALL**
	pqsoPrev->pcallRx	inter's call		**PREVCALL**
	pqsoPrev->pqsoRxSkip	points to his qsoOrig

    pqsoPrev->pcallTx		my call
    pqsoPrev->pstrRxName	name I copied		**PREVNAME**
    pqsoPrev->pqsoTxNext	points to my qsoThis

    pqsoThis->pcallTx		my call
    pqsoThis->pstrTxName	name I sent		**THISNAME**
    pqsoThis->pqsoTxPrev	points to my qsoPrev
    pqsoThis->pcallRx		call I sent name to

    NOTE: the "=" trace char means "received by a log-submitter",
	and "-" means "received by a non-submitter".  note "received by"
	instead of "sent to" -- the tx stn can't print = or - because
	the next rx stn may want to print the tx stn's call first.
