[RTTY] MMTTY receive problems

[Jim Martin]

I was using MMTTY last weekend in CQWW and as always it performed fb.
However I have noticed that very strong signals adjacent to the one I am
decoding cause the spectrum levels to drop almost to zero and it stops
decoding the received signal.  I tried various bandpass settings and also
the 250Hz filter on the MP, narrower filter in the rig helps but the signal
levels still drop.  As no one else has reported this I assume I have messed
up the settings within MMTTY, has anyone any idea which?
I have reloaded MMTTY and reset all the defaults back to HAM with no effect.
This happens on standalone MMTTY and also when used within N1MMLogger.  I am
using a 1GHz PC with 512Mb of memory.
Any pointers appreciated
