Ahh, if that's the file I sent Peter earlier in the week, then you may want
to update to this version: http://rfhead.net/horus/RS41HUP.hex
(The source for which is here: https://github.com/darksidelemm/RS41HUP )

I've removed the gap between transmissions - it now sends MFSK symbols
continuously, which makes the demodulator a little bit happier.

Those changes won't be the cause of the errors you have been seeing however.

Cheers,
Mark
