My problem is understanding how you tell if her radio is
set to AFSK or FSK?
RTTY-L and RTTY-U are FSK. To operate AFSK with any of the Yaesu
transceivers one selects PKT mode. Prior to the FT-9000/FT-2000
PKT was restricted to LSB mode which makes in difficult to use in
some digital modes (QPSK##, JT-65, JT9, MFSK#, etc.) but correct
for AFSK RTTY and usable (with a display difference) for BPSK##.

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.
