[RTTY] Disturbance from station on adjoining freq

[K C Selvadurai]

During a RTTY contest last month, I had spells of difficulty copying the
number given to me in response to my cq call. This was because another
station was transmitting on a frequency close by. 

That station was an overseas station, there is only one other active RTTY
contestor in my home country.

 

I use a FT 1000MP transceiver. What should I be doing to address that
disturbance:

-           Use a narrower filter? 

-           Acquire the 'roofing filter' from Inrad?

-           Some other solution?

 

Many thanks for advice
