[RTTY] Help for FT-1000-MP Mark V

[Gary AL9A]

Looking for some insight into RTTY settings for the Mark V.  I am trying to 
help Corliss AL1G upgrade her RTTY setup, but am unfamiliar with her radio. 
She is in Anchorage and I am about 45 road miles away from her QTH so we are 
doing this via email and phone calls.

She currently has a Rig Expert Standard as her interface, but is going to 
upgrade to a microHAM MKII.  She has MMTTY stand alone running and we are 
trying to get her new upgraded version of WriteLog to use either the MMTTY 
plug in or the XMMT.ocx.  She has been following the tips on AA5AU's web 
site, but she still is having problems getting the radio to key up in 
WriteLog.  At this point I am unsure if she is transmitting AFSK or FSK.

I downloaded the manual for the Mark V and scanned through it looking for 
subjects that included RTTY, AFSK and FSK.  I've discovered that the Mark V 
has two jacks on the back of the radio related to RTTY.  A 5 pin DIN labeled 
PACKET is for AFSK, PSK and other digital modes.  A 4 pin DIN is for FSK. 
My problem is understanding how you tell if her radio is set to AFSK or FSK? 
The manual says to push the RTTY button on the radio to select either RTTY 
LSB  or RTTY USB.  That's it.  So is this AFSK or FSK?  Because of the 
LSB/USB choices it sounds like the radio is going to transmit AFSK with 
either of these settings through the PACKET jack.  I can't find anything in 
the manual that specifically says how to set it to do FSK.  Is there a menu 
item buried somewhere that has to be tweaked in order to get it to transmit 
FSK?  Any guidance appreciated.
