[RTTY] Some basic RTTY radio questions

[Michael Rapp]

Hi all,

Was going over my NAQP notes this weekend.  I have two basic RTTY
radio configuration questions.

My Yaesu FT-950 has two pre-amp settings.  On phone I typically only
engage these on the quieter bands.  I'd use preamp 1 occasionally on
20 meters, and nearly always on 15 and preamp 2 (which amplified more)
always on 10.  On RTTY is this useful or is there something
detrimental to a RTTY decode from using a preamp?

My FT-950 also has three roofing filters settings: 3, 6, and 15 kHz.
I must confess that I really don't understand what a roofing filter
does.  My radio defaults to 3 kHz for RTTY.  Is this okay?

73,
