Thanks for the tips Steve. I can verify that TxFAX is set as a caller:
exten => s,n,Set(FAXFILE=/var/spool/faxoutbound/fax1.tif)
exten => s,n,TxFAX(${FAXFILE}|caller)
I have verified this too with some debug output. The lower pitched
sounds are much shorted than 2s. More like 300ms? I have captured a
sample of the tones here:

I'm not convinced, but this lower pitch sound seems to interfere with
the initial higher pitch sound which I usually hear from other fax
machines and may be causing the other end not to recognise the tone
correctly? Like I said, if I put the fax machine in 'fax only' mode the
fax goes through fine. Is this because in fax only mode the recipient
sends tones back to TxFax, but in dual fax/tel mode the fax machine
'listens' for fax tones only?
Any advice you have would be greatly appreciated.
Cheers,
Ray
