HELP!

Trying to get on for a few mins in RTTY RU to give out a few Q's but not 
much experience with RTTY. If someone isn't playing seriously maybe could 
help me with what looks like a setup problem. I can't make any sense out of 
the manuals and troubleshooting.

Computer/software: Pentium/Soundblaster/Windows XP with N1MM calling up 
MTTY.

Radio: Orion II
Audio gets to sound card OK from AUX out of Orion. When radio set to LSB no 
copy but plenty of stuff on the waterfall.  Can't make any peaks get between 
the "telegraph poles." However, when I set the Orion mode to FSK, I get 
perfect rx copy. However, I don't have TNC and TNC connection to radio so 
can't use true FSK. (On TX in FSK mode it just transmits a continuous 
carrier with no frequency shift, so obviously need to use sound card mode on 
LSB.

How do I get an offset, or whatever it is so sound card/N1MM reads the RTTY 
on LSB as it does on FSK mode? And if it transmits, will the shift be 
correct?

If there's a quick answer someone please email. If someone knows the answer 
and will talk me through it, I can  call. Just give me a phone number.

Many thanks, 73
